How to Create Your Own DeFi Wallet?

The rapid evolution of decentralized finance (DeFi) is transforming how users manage their digital assets. One of the core tools powering this transformation is the DeFi wallet, a secure, non-custodial application that enables seamless interaction with decentralized services. Unlike traditional wallets provided by centralized exchanges, DeFi wallets offer complete ownership, enhanced privacy, and direct access to a wide range of DApps. If you're exploring custom DeFi wallet development services for your business or personal project, this comprehensive guide walks you through the essential steps to create a secure, scalable, and user-friendly wallet tailored to your needs.

What is a DeFi Wallet?

DeFi wallet refers to the digital wallet that enables users to send, receive, store and manage cryptocurrencies without using third parties. This type of wallet is non-custodial, so holders keep the keys of their cryptocurrency and, consequently, their money.

In contrast to centralized wallets where the data about the user and its assets is stored on their backend, DeFi wallets are purely on balance. That is why they are perfectly usable when it comes to DeFi services that allow lending, borrowing, staking, and trading using the integrated DApps.

Examples of Popular DeFi Wallets

Some widely recognized decentralized finance (DeFi) wallets include MetaMask, Trust Wallet, and Argent, each offering unique features for managing digital assets securely. These wallets have turned out to be the norms of working with decentralized environments and are being used as yardsticks to upcoming wallet projects.

Essential Features of a DeFi Wallet

In order to create a DeFi wallet that can stand out, you have to add the necessary features which have to satisfy the users in security, functionalities, and user experience.

Non-Custodial Design

The wallet should be fully non-custodial, whereby customers can create and keep their own private keys. Backup and recovery should be by means of a 12/24-word seed phrase.

Multi-Chain and Token Support

The possibility of utilizing several blockchains such as Ethereum, BNB Chain, and Polygon is necessary. The wallet must also support different token standards like ERC 20, BEP and others.

DApp Integration

Allow the users to connect with decentralized apps by WalletConnect or an in-app DApp browser. This improves usability and forms a frictionless DeFi.

Intuitive User Interface

The wallet interface should be clean, intuitive, and easy to navigate for users of all experience levels. New users must be able to onboard in a fast way and not get confused performing simple actions such as sending and receiving tokens.

Advanced Security Measures

Introduce biometric identification, Personal identification Number (PIN) locks, and Local encryption. Ensure that the keys never stay on the central server.

Step-by-Step Guide to Creating a DeFi Wallet

Step 1: Choose Your Blockchain

Choose the blockchain networks, which your wallet is going to work with. Ethereum has a rich ecosystem but it is costly because of the high gas prices. Alternative networks like BNB Chain and Polygon offer lower transaction fees and faster processing times compared to Ethereum.

Step 2: Decide on Wallet Type

Decide to develop a mobile application (iOS / Android), an extension in the browser (such as MetaMask), a web-based wallet, or a desktop application. You should choose it in terms of your users and use case.

Step 3: Set Up Your Development Tools

Front-end development frameworks can be used, including React Native on mobile wallets or Flutter where compatibility is required. To communicate with blockchain networks, one can use Web3.js or Ethers.js libraries or view. To the project of establishing contacts with blockchain nodes, you may think of Infura, Alchemy, or Moralis providers.

Step 4: Design a User-Friendly Interface

Concentrate on providing an intuitive user interface that streamlines operations of the wallet. Moreover add is clear navigation for creating wallet, token balance, send and receive token and for use in DApps. Responsiveness and accessibility should always be in the prioritized list.

Step 5: Implement Core Wallet Functions

Integrate core features such as:

Private key and seed phrase generation

Token transfers

Transaction history display

Token import by contract address

Real-time balance updates

Make sure all private key operations happen locally on the user’s device.

Step 6: Integrate DApp Connectivity

Allow connecting the users to decentralized applications with WalletConnect or integrating a Web3-compatible browser. This will enable your users to engage in DeFi environments such as Uniswap, Aave and Compound without visiting a third-party environment.

Step 7: Apply Security Best Practices

The wallet should be locked with encryption of sensitive data, the device secure keystore and the use of biometrics or PIN. Review the code to both find and patch vulnerabilities prior to release.

Step 8: Conduct Thorough Testing

Test the wallet in blockchain testnets to ensure they are all functioning well before it is launched. Recreate application use case scenarios including transactions, DApp connectivity and wallet recovery. It should test through manual user testing and automated testing on devices and platform operating systems.

Step 9: Deploy and Maintain

After your wallet is tested, you can then deploy it on the platforms. For mobile wallets, ensure your application is submitted to the Apple App Store and Google Play Store. If you're developing a browser extension, publish it on the Chrome Web Store for wider accessibility. Once launched, track performance, user feedback and security to update and refine it on a regular basis.

Final Thoughts

Creating a DeFi wallet yourself should be considered a strategic management project, as it may help you become an important participant in the emerging decentralized economy. Whether it comes to choosing proper blockchain and wallet type or add powerful functionality and tight security, all these steps must be carefully thought out. As the Web3 industry grows, the possibility to provide its users with more control over their finances by offering them a secure and user-friendly DeFi wallet is not the opportunity anymore but the necessity. As a startup in the blockchain industry or a developer seeking to innovate, it would be the right time to make a wallet that would give power to the future of decentralized finance.

EMR Studio Features Requirements and Limits AWS

Amazon EMR Studio features, specs, and limitations:

Amazon EMR Studio describes an IDE for data preparation and visualisation, departmental collaboration, and application debugging. When utilising EMR Studio, consider tool usage, cluster demands, known issues, feature constraints, service limits, and regional availability.

Features of Amazon EMR Studio

Service Catalogue lets administrators connect EMR Studio to cluster templates. This lets users create Amazon EC2 EMR clusters for workspaces. Administrators can grant or deny Studio users access to cluster templates.

The Amazon EMR service role is needed to define access permissions to Amazon S3 notebook files or AWS Secrets Manager secrets because session policies do not allow them.

Multiple EMR Studios can control access to EMR clusters in different VPCs.

Use the AWS CLI to configure Amazon EMR on EKS clusters. Connect these clusters to Workspaces via a controlled API in Studio to run notebook jobs.

Amazon EMR and EMR Studio use trusted identity propagation, which has extra considerations. IAM Identity Centre and trusted identity propagation are required for EMR Studio to connect to EMR clusters that use it.

To secure Amazon EMR off-console applications, application hosting domains list their apps in the Public Suffix List (PSL). Examples are emrappui-prod.us-east-1.amazonaws.com, emrnotebooks-prod.us-east-1.amazonaws.com, and emrstudio-prod.us-east-1.amazonaws.com. For sensitive cookies in the default domain name, a __Host- prefix can prevent CSRF and add security.

EMR Studio Workspaces and Persistent UI endpoints use FIPS 140-certified cryptographic modules for encryption-in-transit, making the service suitable for regulated workloads.

Amazon EMR Studio requirements and compatibility

EMR Studio supports Amazon EMR Software versions 5.32.0 and 6.2.0.

EMR clusters using IAM Identity Centre with trusted identity propagation must use it.

Before setting up a Studio, disable browser proxy control applications like FoxyProxy or SwitchyOmega. Active proxies can cause Studio creation network failures.

Amazon EMR Studio restrictions and issues

EMR Studio does not support Python magic commands %alias, %alias_magic, %automagic, %macro, %%js, and %%javascript. Changing KERNEL_USERNAME or proxy_user using %env or %set_env or %configure is not supported.

Amazon EMR on EKS clusters does not support SparkMagic commands in EMR Studio.

All multi-line Scala statements in notebook cells must end with a period except the last.

Amazon EMR kernels on EKS clusters may timeout and fail to start. Should this happen, restart the kernel and close and reopen the notebook file. The Restart kernel operation requires restarting the Workspace, and EMR on EKS clusters may not work.

If a workspace is not connected to a cluster, starting a notebook and choosing a kernel fails. Choose a kernel and attach the workspace to run code, but ignore this error.

With Amazon EMR 6.2.0 security, the Workspace interface may be blank. For security-configured EMRFS S3 authorisation or data encryption, choose a different supported version. Troubleshooting EMR on EC2 tasks may disable on-cluster Spark UI connectivity. Run %%info in a new cell to regenerate these links.

5.32.0, 5.33.0, 6.2.0, and 6.3.0 Amazon EMR primary nodes do not have idle kernels cleaned away by Jupyter Enterprise Gateway. This may drain resources and crash long-running clusters. A script in the sources configures idle kernel cleanup for certain versions.

If the auto-termination policy is enabled on Amazon EMR versions 5.32.0, 5.33.0, 6.2.0, or 6.3.0, a cluster with an active Python3 kernel may be designated as inactive and terminated since it does not submit a Spark task. Amazon EMR 6.4.0 or later is recommended for Python3 kernel auto-termination.

Displaying a Spark DataFrame using %%display may truncate wide tables. Create a scrollable view by right-clicking the output and selecting Create New View for Output.

If you interrupt a running cell in a Spark-based kernel (PySpark, Spark, SparkR), the Spark task stays running. The on-cluster Spark UI is needed to end the job.

EMR Studio Workspaces as the root user in an AWS account causes a 403: Forbidden error because Jupyter Enterprise Gateway settings disallow root user access. Instead of root, employ alternate authentication methods for normal activities.

EMR Studio does not support Amazon EMR features:

connecting to and running tasks on Kerberos-secured clusters.

multi-node clusters.

AWS Graviton2-based EC2 clusters for EMR 6.x releases below 6.9.0 and 5.x releases below 5.36.1.

A studio utilising trusted identity propagation cannot provide these features:

Building EMR clusters without templates using serverless applications.

Amazon EMR launches on EKS clusters.

Use a runtime role.

Supporting SQL Explorer or Workspace collaboration.

Limited Amazon EMR Studio Service

Service Restriction The sources list EMR Studio service limits:

EMR Studios:

Each AWS account can have 100 max.

Maximum five subnets per EMR Studio.

IAM Identity Centre Groups are limited to five per EMR Studio.

EMR Studios can have 100 IAM Identity Centre users.

Exploring Node.js 23 and What’s Next for Node.js?

Node.js keeps getting better, and Node.js 23 is a solid step forward. This version brings some important changes. It trims down some complexity and helps developers write cleaner, more modern JavaScript. If you're working in Node.js web development, these updates can help your team work faster and more efficiently.

Let’s go deeper into what Node.js 23 brings, how it affects real projects, and where Node.js is headed.

Simpler Module Imports with Native ES Modules

Before Node.js 23, using ES modules wasn’t very smooth. You had to name files with .mjs, or add special settings in package.json. Now, Node.js 23 enables native ES module support by default.

This means:

You can use import and export in your .js files with fewer roadblocks.

No need to fiddle with extensions or file naming conventions.

The transition from browser JavaScript to server-side JavaScript gets easier.

This update helps Node.js development services write code that’s modern, consistent, and easier to maintain.

New node --run Feature Goes Stable

There’s a small new feature in this release — but it’s powerful. The node --run command is now stable. That means you can run small scripts straight from the terminal, without needing a full file setup.

For example:

bashCopy

Edit

node --run "console.log('Hello, Node.js 23')"

This is a game-changer for developers who test snippets or debug issues daily. You can try ideas fast, and move on without cluttering your project folder with test files.

If your team uses Node.js development services professionally, this makes development and QA faster.

Test Runner Upgrades

Node.js comes with a built-in test runner now, and it’s getting better. In v23, you can pass glob patterns to select specific files for test coverage. That gives you more control when running tests — which matters for larger apps.

Example:

bashCopy

Edit

node --test --coverage "tests/**/*.spec.js"

This lets teams run targeted tests without unnecessary overhead. It makes things neat, which is what good Node.js web development should be about.

Better Performance for Buffers and Files

Performance in Node.js has always been one of its selling points. With v23, the internal workings of buffer handling and file system modules are faster.

What this means for you:

Faster read/write operations.

Better performance under heavy I/O loads.

More efficiency when building apps like file managers, stream processors, or media servers.

If you're planning to hire Node.js developers, performance tuning like this makes the platform more reliable for production-scale apps.

Experimental Additions: Try Carefully

Node.js 23 also introduces a few experimental features. These aren’t ready for production, but they give us a glimpse into the future.

1. TypeScript Transforms

You can now experiment with built-in TypeScript transformations using a new CLI flag. This might let devs skip extra tools like Babel or ts-node in the future.

Why it matters:

Fewer external dependencies.

Faster build times.

Simpler setup for TypeScript-based Node.js web development.

2. SQLite Built-In Support

SQLite is popular for small apps and embedded systems. Node.js 23 introduces experimental support for SQLite with no third-party library needed.

If this becomes stable in future releases, teams could build local-first apps using just Node and SQLite.

A huge win for bootstrapped teams that want to hire dedicated Node.js developers for quick MVPs or embedded applications.

Removed: 32-Bit Windows Support

This release drops support for 32-bit Windows systems. For most people, that’s no problem. But it’s good to know if you’re supporting older hardware.

This move helps the Node.js core team reduce overhead and optimize performance for modern machines.

What’s Next for Node.js?

The updates in Node.js 23 are useful, but they also hint at where Node.js is going next. Let’s talk about what’s likely to come in the next few versions.

1. Serverless Workloads Are Growing

Serverless is a hot area. And Node.js fits well into this model because of its non-blocking nature. Whether it’s AWS Lambda or Vercel functions, Node.js powers many backend functions in modern web stacks.

More frameworks will be built around serverless. That means developers will need to hire Node.js developers who understand event-driven design deeply.

2. WebAssembly (WASM) Will Be Key

WebAssembly support in Node.js keeps improving. WASM runs low-level code fast, almost like native apps.

Soon, Node.js web development won’t be limited to JavaScript. Developers will use Rust, C++, or Go to build modules and run them in Node.

This expands what’s possible. Heavy-duty processing, ML models, or video encoding? Node + WASM makes it possible.

3. Edge Computing Needs Lightweight Runtimes

CDNs are turning into compute platforms. Tools like Cloudflare Workers or Vercel Edge Functions are already doing this. Node.js has to keep up.

Expect the next versions to focus more on small memory footprints, fast cold starts, and edge-optimized features. Lightweight and modular Node.js development services will become even more valuable.

Why It All Matters

Each new Node.js version adds something small but meaningful. It’s not about flash — it’s about control, speed, and developer comfort.

If you want to hire dedicated Node.js developers or build a strong team, look for people who know what’s under the hood — who follow releases, understand what’s stable vs. experimental, and use features like ES modules the right way.

Node.js development services are maturing. The ecosystem is better tested, faster, and easier to work with than it was five years ago.

Final Thoughts

Node.js 23 doesn’t flip the table — but it clears the table. It gets rid of some mess. It lines things up. It makes future releases easier to build upon.

For companies relying on Node.js web development, that’s the kind of progress you want — not hype, but confidence. You want a stack that gets better without breaking everything.

If you’re planning to hire Node.js developers, now is a good time to focus on building apps that are clean, lean, and built to scale. With each new release, Node.js is giving teams the tools to do just that.

Introduction

When an Ethereum wallet is built from the bottom up, companies have total control over security, customisation, and compliance. By understanding the fundamental principles of Ethereum architecture, developers can design an Ethereum wallet that satisfies specific business needs. This guide will show users the primary steps to create Ethereum wallet like metamask solutions.

What is Ethereum wallet?

An Ethereum wallet is only a hardware or software interface designed especially for Ethereum-based token management and storage (ETH). Unlike most of the conventional wallets which used to keep physical cash, Ethereum wallets save the secret keys to switch access for the assets or applications that existed on the Blockchain. Ethereum assets are not stored directly in the wallet; instead, they are stored on the blockchain itself. The keys to access, move, and work with those assets are only stored in the wallet.

Why Build an Ethereum Wallet?

The company has complete control over user access, transaction flows, and private key management by creating an Ethereum wallet specifically for it. Unlike a third-party wallet, a bespoke solution allows for interaction with internal systems, custom security protocols, and compliance elements tailored to the internal requirements, such as KYC/AML.

It enables businesses to support various asset kinds, provide on-brand blockchain experiences, and communicate directly with smart contracts. Building a dedicated Ethereum wallet is a strategic benefit as blockchain use increases, as it reduces reliance on other providers and offers scalability, flexibility, and long-term cost savings in the Web3 and decentralized applications ecosystem.

Steps to Build a Ethereum Wallet

The steps in building an Ethereum Wallet are strategic and technical at the same time, especially when it is meant for business use.

Define Business Requirements

Choose the Right Tech Stack

Design the Architecture

Develop the Frontend & Backend

Implement Security Measures

Test & Deploy

Define Business Requirements

The first step in creating Ethereum wallets is defining your business needs. Identify where the wallet will be used: for asset management, employee transactions, or perhaps for integration into decentralized finance (DeFi). What are the features needed? Regulatory compliance (KYC/AML), support for multiple users, and adaptability to your business procedures are all factors to take into account. 

Choose the Right Tech Stack

For the Ethereum wallet development process to be as efficient as possible, the appropriate tech stack must be used. Web3.js and Ethers.js are two examples of libraries used to perform interactions on the Ethereum network. Use infrastructure tools such as Infura or Alchemy for scalable Ethereum network access. 

Design the Architecture

The architecture design of the wallet ought to consider security, scalability, and user experience. Secure key storage should be planned, hardware wallets, or through encrypted vaults. It should include a clear backend infrastructure regarding the creation of wallets, transaction signing, and interaction with the blockchain. There should be efficient communication with the nodes of Ethereum via API without compromising the more user-friendly frontend that interacts with the wallet.

Develop the Frontend & Backend

The front-end of your Ether wallet should create a simple experience with interface elements for user interaction with the wallet; wallet network for creating wallets initiating transactions and checking balances. On the other hand, the logic will be created towards safely managing the privacy of keys, transacting with these keys, as well as interaction with the Ethereum Blockchain.

Implement Security Measures

End-to-end encryption must be implemented for the storage of private keys and data. Multi-factor authentication (MFA) and biometrics can be enforced for authorized access. Add multi-signature support and role-based access controls to protect high-value assets for additional levels of security. 

Test & Deploy

Carry out unit and integration testing to ensure functionality and smooth performance across different scenarios. Test edge cases, security flaws, and high traffic scenarios to make sure that your wallet is scalable. Then, use a secure cloud or on-premise infrastructure for deploying your wallet. 

Types of Ethereum Wallet

When storing private keys, one can choose from various options, the safest being the first one moving down the line to the easiest access. Consider the importance of your private keys and choose a wallet which is the best for you. Here are the types of wallets: 

Software wallets

Hardware wallets

Paper wallets

Software wallets

A software wallet which is also known as a wallet application is basically an application that allows a user to HODL, send, and receive cryptocurrencies. Holders provide easy interfaces to work with blockchains through the graphical user interface where cryptocurrencies are technically stored on-chain.

Hardware wallets

A hardware wallet is a standalone physical device, usually shaped like a USB drive that holds cryptocurrencies securely without being connected to any network. Such types of wallets come under the segment of cold wallets-these have a physical entity not connected to any network, making it all the more secure from all types of threats software vulnerabilities and web viruses.

Paper wallets

The wallet made of paper refers to a file of paper that carries out your private and public keys in written form. That is a technique to keep and take access to the cryptocurrency offline. Printing out the keys brings them off from the cryptocurrency network, although the tokens still stay there out of reach without the keys.

Advanced Features for Ethereum Wallet

Ethereum wallets should offer more than just handling standard transactions in order to fulfill contemporary business requirements. They must also present advanced features for increasing security, usability, and flexibility:

Multisignature Support

Role-Based Access Control

Gas Fee Optimization

Hardware Wallet Integration

Decentralized Exchange Integrations

Multisignature Support

An advanced type of cryptocurrency wallet with an extra set of security settings is called a multi-signature wallet. Generally, these require two or more persons to approve the sending of an outgoing transaction. Multi-sig is another name for this concept and is mainly useful when the cryptocurrency or any digital assets are co-owned by several individuals or are held in custody by some company.

Role-Based Access Control

Role-Based Access Control is a security mechanism that offers users access to systems, applications, and data depending on the organizational roles they hold. RBAC focuses on assigning permissions to roles instead of users; it is the assignment of these roles to users that is put into effect. This user-friendly approach allows for access management to be greatly simplified, ensuring users are granted only the necessary access for their job functions.

Gas Fee Optimization

Gas fees optimization within a blockchain-technology- and DeFi-oriented environment, therefore, encompasses a suite of strategies, methods, and mechanisms to reduce transaction costs in the blockchain domain. This is highly relevant on certain networks like Ethereum, where gas fees can be high.

Hardware Wallet Integration

It means that hardware wallet integration refers to linking a real device hardware wallet to any software wallet or platform so that it can be used as protection for private keys and enable an offline signing mechanism for transaction signatures. It could be simply defined as a way to enhance security against online attacks and allow more secure public storage of the cryptocurrency assets.

Decentralized Exchange Integrations

Integrations of Decentralized Exchange (DEXs) include connecting or incorporating DEX services with other platforms. This will expand the accessible asset classes to include more trade strategies for users and may enhance liquidity across exchanges.

Conclusion

Creating Ethereum wallets allows organizations to take total control over safety, extent, and compliance. Designing your own wallet features around needs like multisig, role-based access, and DeFi integration would allow companies to cleanly manage internal blockchain operations and provide a competitive advantage in the digital economy. Custom wallets are solutions for tomorrow.

Social Network Analysis Programming

Social Network Analysis (SNA) is a powerful technique used to explore and analyze the relationships between individuals, groups, or entities. With programming, we can visualize and calculate complex network structures, which is useful in fields like sociology, marketing, cybersecurity, and even epidemiology.

What is Social Network Analysis?

Social Network Analysis is the process of mapping and measuring relationships and flows between people, groups, organizations, computers, or other information/knowledge processing entities. It reveals the structure of networks and helps identify influential nodes, communities, and patterns.

Key Concepts in SNA

Nodes (Vertices): Represent entities (e.g., people, computers).

Edges (Links): Represent connections or relationships between nodes.

Degree Centrality: Number of direct connections a node has.

Betweenness Centrality: How often a node appears on shortest paths.

Clustering: Grouping of nodes based on similarity or proximity.

Tools & Libraries for SNA Programming

Python: Powerful language with strong libraries like NetworkX and Pandas.

NetworkX: Used to create, manipulate, and visualize complex networks.

Gephi: GUI-based open-source software for large network visualization.

Graph-tool (Python): Fast and efficient network analysis for large graphs.

D3.js: JavaScript library for dynamic and interactive network visualizations.

Example: Basic Network Analysis with Python & NetworkX

import networkx as nx import matplotlib.pyplot as plt # Create a graph G = nx.Graph() # Add nodes and edges G.add_edges_from([ ('Alice', 'Bob'), ('Alice', 'Carol'), ('Bob', 'David'), ('Carol', 'David'), ('Eve', 'Alice') ]) # Draw the network nx.draw(G, with_labels=True, node_color='lightblue', edge_color='gray') plt.show() # Analyze print("Degree Centrality:", nx.degree_centrality(G)) print("Betweenness Centrality:", nx.betweenness_centrality(G))

Applications of Social Network Analysis

Marketing: Identify key influencers and optimize content spread.

Security: Detect suspicious communication patterns or malware spread.

Epidemiology: Track the spread of diseases across populations.

Sociology: Understand community structures and social behavior.

Recommendation Systems: Suggest friends, content, or connections.

Tips for Effective SNA Programming

Start with clean and structured data (CSV, JSON, etc.).

Visualize early and often to detect patterns.

Use metrics like centrality and clustering coefficients for deeper insights.

Leverage real-world datasets like Twitter or Facebook data via APIs.

Scale with performance-optimized libraries for large datasets.

Conclusion

Social Network Analysis Programming unlocks a new dimension in data analysis by focusing on relationships rather than isolated entities. With the right tools and mindset, you can uncover hidden structures, detect influence patterns, and make data-driven decisions in a connected world.

Node js V12 – What are the new features in Node js V12

Node.js has been committed about their yearly updates the new features. This year their new version — V12 named Erbium is out. Here is an honest, unbiased review. Before jumping straight into the new features of Node js V12, what Node.js is let me paint what it is and what it does. Node.js is an open source framework that runs on Chrome’s V8 JavaScript engine.  It supports every OS on the market — MAC, Linux and Windows and easy on your budget.

What is Node.js?

Node.js is a platform, that supports building secure, fast and scalable network applications. Node.js is an event-driven model that doesn’t drag and is efficient for data-intensive real-time application that runs across distributed devices. Now, lets see briefly about the features in Node js V12

TLS 1.3 is now used by default Max protocol

TLS stands for Transport Layer Security, that secures communication between servers and browsers. Another notable thing about this feature is that this is the default Max protocol that offers to switch off in the CLI/NODE_OPTIONS. It is comparatively faster than TLS1.2.

Async Stack traces

Another noteworthy feature is to trace the errors of Async Stack. Previously, we won’t trace the errors in the Async await functions. Now, developers can easily do so using the asynchronous call frames of the error.stack property

Let me show you an example,

async function wait_1(x) { await wait_2(x) } async function wait_2(x) { await wait_3(x); } async function wait_3(x) { await x; throw new Error(“Oh boi”) } wait_1(1).catch(e => console.log(e.stack));

This output terminal instantly shows additional details. In this version, we can easily debug the async/wait functions.

Parser

The Node.js v12 switches default http parser to ||http that improves the llhttp-based implementation drastically.

Purpose of heap dumps

Another notable update in the Node.js V12 is the integrated heap dump capability an out of the box experience to examine the memory issues.

Heap size configuration

In V8, the max heap size was limited to 700MB and 1400MB on 32-bit and 64-bit platforms, respectively. The updated version of Node.js V12 supports automation, that ensures the heap size helps to process the large data sets.

Startup time establishment

According to the new release of Node.js V12, improves startup speed approximately 30 % for the main thread. It developed the build time for code cache in built-in libraries and embedded it as a binary. Also it improves the performance in JavaScript parsing

N-API performance in Node.js V 12

Node.js V12 supports enhanced N-API in combination with worker threads. The concept of N-API brings stable and enabled native node modules that can prevent ABI-compatibility come across various Node.js versions.

Runtime engine upgrade to 7.4

The Node.js V12 runs on V8 JavaScript engine which is upgraded to 7.4 and eventually will upgrade to 7.6. It brings the stability with the help of Application Binary Interface (ABI). Additionally, it provides high speed execution, supports ECMAScript syntax, secured memory management and so on.

Compiler

For code base, the minimum requirement of the compiler is GNU Compiler Collection (GCC) 6 and glibc 2.17 on platforms other than MAC OS and Windows. The Node.js is now fully facilitated with optimized compiler and high-level security. Nodejs.org released binaries that use a new tool-chain minimum and it provides efficient compile-time and upgraded security.

Diagnostic report

Last but not least, Node.js includes the additional feature is diagnostic report. It generates the report On-Demand that will be hit by any particular event. The user can ability to identify the abnormal termination in production such as performance, crashes, memory leaks, CPU usage, irrelevant output etc.

This article covers the noteworthy features of the Nodejs Erbium recent version.

 List of essential features: Identify the essential features that users need to achieve the main objectives of the application. For a project management application, basic functions may include assigning tasks, tracking deadlines, and sharing documents.

 Prioritize features for MVP: Start with a minimum viable product (MVP) to launch quickly and get feedback. Choose features that provide maximum value with minimum complexity. For example, you prefer secure login and task creation to advanced reporting features in your initial project management application.

 Plan for future expansion: Although we focus on core features first, it is useful to list additional features that you can add after launch based on user feedback, such as notifications or integration with third-party tools.

3. User interface and user experience design (UI/UX)

Effective design is about balancing aesthetics and usability, ensuring that users can navigate and use the app smoothly.

 Wireframes and prototypes: Start with simple wireframes, which are layout plans for your app that show the placement of buttons, text, and images. Then they create interactive prototypes to simulate the user journey and identify potential roadblocks.

 Focus on user-centered design (UX): User experience design considers how users interact with your app. Try to make navigation intuitive and actions like registration and checkout seamless. Prioritize ease of use by keeping flows as simple as possible.

Create a visual aesthetic (UI): Visual elements such as color schemes, typography and button styles create the app's personality and should be consistent with your brand. Consistent images build user confidence, so avoid cluttered screens or flashy graphics.

4. Technology Package Selection

The technology stack is the combination of tools, programming languages, and frameworks needed to build and run your application.

Front-end technology: The front-end is the part of the application that users interact with. HTML, CSS and JavaScript are essential, while frameworks like React. js, See. js or Angular can simplify development by providing reusable components and interactive capabilities.

Backend Development: Backend takes care of data management, server logic and storage. Choose a language and framework that fits the needs of your application, such as Node. js for complete JavaScript-based applications, Django (Python) for rapid prototyping, or Laravel (PHP) for complex applications. 

Databases and storage solutions: Store your data with SQL databases (such as MySQL, PostgreSQL) for structured data or NoSQL databases (such as MongoDB) if your data is not structured or require flexibility.

Hosting and deployment options: Choosing the right hosting provider is crucial for performance and scalability. Options like AWS, Heroku, and Google Cloud offer reliable hosting with scalability, monitoring, and built-in security features.

5. Development and testing of MVP

Creating an MVP allows you to quickly release a working version of your app and get real user feedback.

Start with core features: Focus on building the core features outlined in your MVP plan. Break each function down into smaller tasks and complete them step by step so you don't feel overwhelmed.

Application testing: Testing is necessary to identify bugs, ensure stability and verify that the application works on different devices and browsers. Manual testing helps uncover usability issues, while automated testing speeds up the process by validating repetitive tasks.

User Testing: Conduct beta testing to release the MVP to a limited set of users. Gather information about their experiences and look for patterns in their comments. This will help you prioritize future updates.

6. Refinement of the application based on feedback

User feedback is essential to understand how your app performs in real-world situations and to highlight areas for improvement.

Analyze feedback methodically: Categorize feedback into categories such as usability, performance, and features. Identify recurring issues as they represent the most urgent areas that need attention. 

Iterate to improve: Focus on the most important feedback first, starting with blockers that affect core functionality or user experience. Introduce changes gradually and focus first on impressive improvements.

Scalability improvement: As feedback drives further improvements, consider upgrades to support increased use, such as optimizing database queries, improving security measures, and ensuring that the application can handle a growing number of users.

7. Preparation for launch

The launch is the first step of your app. It is therefore essential to plan a successful exit.

Final testing and quality assurance: Perform final testing of all app features and ensure that it is stable, secure and free of major bugs. Pay attention to compatibility between different devices and browsers. 

Integrate analytics tools: Use tools like Google Analytics, Mixpanel, or Firebase to track how users interact with your app after launch. The analysis provides insight into user behavior, identifying known characteristics and areas for improvement.

App Marketing: A successful launch requires a solid marketing strategy. Use social media, digital advertising, email marketing and industry influencers to spread the word about your app and engage your target audience. Consider creating video demos or tutorials that demonstrate the value of your app.

8. Track and schedule future updates

The app is an evolving product that grows and improves over time, based on user needs and market trends.

Continuous monitoring and feedback collection: Monitor performance indicators such as user retention, visit duration and refund rate. This data reveals how users interact with your app and highlights areas for improvement.

Regular updates and improvements: Schedule regular updates to add new features, optimize performance, and meet user expectations. Resolves security vulnerabilities and compatibility issues as needed.

User Engagement: Build a community around your app by interacting with users through in-app messaging, email newsletters, or social media. A loyal user base will give you valuable feedback and help you promote your app.

Conclusion

Building a web application from scratch requires careful planning, a clear idea of ​​the target audience, and a structured approach to development and testing.While this may sound like a complex process, breaking it down into manageable steps can make the journey easier and more efficient. From defining your idea and creating an MVP to gathering user feedback and preparing to launch, each step plays a vital role in the success of your app.Consistent improvement and patience are key to achieving success with your web application.

Node JS and Databases

Steps to Build a Blog Application

1. Project Setup

First, you create a new Node.js project on your computer.

You also install necessary tools like Express (for creating a web server) and Mongoose or MySQL (for interacting with the database).

Nodemon can be used during development to restart the server automatically when code changes.

2. Folder Structure

Organize your project files so that everything is easy to manage.

Models: This folder will store database schemas (like the blog post structure).

Routes: These handle requests to different parts of your blog (e.g., showing all posts or creating new ones).

Views: These are the templates used to render your pages (like home, post details).

Public: A place for static files (CSS stylesheets, images).

3. Setting Up the Database

You can use either MongoDB (a NoSQL database) or MySQL (a relational database) to store your blog posts.

MongoDB is easier for beginners because you don't need to define strict tables.

You create a "Blog" model, which defines the structure of each blog post (e.g., it should have a title, content, and a timestamp).

The database connection is established at the beginning so the app can interact with it throughout.

4. Handling HTTP Requests with Express

The Express framework helps manage the flow of the app:

When a user visits the home page, the server sends a list of all blog posts.

When they click on a specific post, it shows the details of that post.

There is also a form where users can create new posts by submitting titles and content.

You create routes to manage these requests. Each route corresponds to a specific URL (e.g., / for the home page, /post/:id to view a post).

5. Creating Views (Templates)

To make your pages dynamic, you use EJS (or another templating engine like Handlebars). Templates allow you to display different content based on the data from the database.

For example:

The home page lists all available blog posts with links to view them individually.

The post page shows the title, content, and date of a single post.

There can also be a form on the home page that lets users submit new posts.

6. Routing and User Interaction

When users visit the homepage, the server pulls data from the database and shows a list of posts.

Clicking on a post’s link takes them to a detailed view of that post.

Users can also add a new post by submitting a form. When they do, the app saves the new post in the database and refreshes the list.

7. Starting the App

You need to make sure both the database server and Node.js app are running.

MongoDB needs to be started separately (if using it).

The Node.js server listens for requests and responds based on the routes you’ve created.

The server is accessible via http://localhost:3000. You can open this in a browser to test the blog app.

8. Testing the Blog API (Optional)

To make sure everything works correctly, you can use tools like Postman to test your routes:

Test retrieving all posts by making a GET request.

Test creating a new post by sending a POST request with sample data.

You can also build error handling to manage invalid inputs.

9. Future Improvements

After setting up the basic blog, you can add advanced features:

User Authentication: Allow users to log in and manage their own posts.

Comments: Add a comment section for each post.

Pagination: Break long lists of posts into pages for better readability.

CSS Styling: Make the blog look more attractive with a custom stylesheet.

Summary

This blog app involves setting up a Node.js server, connecting it to a database to store posts, and using templates to render pages. When users visit the blog, they can view, create, or manage posts, all of which are stored in the database. Express routes manage the requests, and the views ensure everything is displayed neatly.

This project gives you hands-on experience with backend development using Node.js, along with frontend templates, and a solid understanding of working with databases.
