Unlocking the Power of Microservices Architecture with CloudKodeForm.

In today’s quick-changing digital world, businesses must find ways to innovate fast without risking system stability. That’s where microservices architecture is useful. At CloudKodeForm, we focus on creating, building, and launching microservices architecture that are scalable, strong, and independent, helping modern apps run smoothly.

What Are Microservices?

Microservices are a style of building applications as small, self-contained services. Each service focuses on one business task. Unlike large, monolithic apps where everything is connected, microservices offer more flexibility, easier updates, and better scaling.

Each microservice works on its own, communicates through simple protocols like HTTP, REST, or messaging queues, and can be added or expanded without disrupting the whole system.

Why Use Microservices?

Microservices give many advantages:

Scalability: You can grow each service separately when needed.

Faster Launches: Teams can develop, test, and release each service independently.

Reliability: If one service fails, the rest keep working.

Technology Choices: Teams can pick the best tools or programming languages for each service.

At CloudKodeForm, we help clients switch from old systems into microservices or create new systems that are custom-built for their needs.

Java Microservices with Spring Boot

Using Spring Boot is one of the best ways to build java microservices. Spring Boot is lightweight and ready to use. It makes setting up services quick and simple. It has built-in features like embedded servers, health checks, monitoring, and security that speed up development.

We use Spring Boot to help companies modernize their systems. With tools like Spring Cloud, Eureka, and Zuul, we easily add service discovery, load balancing, and shared settings.

From making APIs to connecting databases, our Java team makes sure your services are strong, safe, and easy to update.

Node.js Microservices for Fast Applications

For apps that handle many requests at once or need real-time updates, Node.js microservices work well. Node.js handles multiple tasks at the same time without slowing down.

At CloudKodeForm, we use Node.js to build efficient microservices for chat apps, live streams, and IoT projects. We make sure they run well and connect easily with other services and data sources.

Why Choose CloudKodeForm?

Specialists in Many Technologies: Whether it’s Spring Boot or Node.js, our team has deep experience. Full Services Offerings: We handle everything—from design to deployment and ongoing support. Built for the Cloud: We create services that work well with cloud platforms and containers like Docker and Kubernetes.

Still struggling with insomnia so I did more research for PierMesh. I want to keep the code base simple and consistent so I'm looking at using python for the one board/transceiver only setup for mobile users. The main issue here is that unless something changes we cannot use the serial connection without modifying the code significantly on a mobile device running ios/android.

I was gonna say oh well that means we use bluetooth because the http api has no authentication mechanism but since this research is about single user mode I think that's okay because you still have to login to the wifi the board provides with a key you can set via the meshtastic provided bluetooth interface.

That all said here's the plan: write a small adapter js lib to interact with the http endpoint and connect that into the existing architecture so that with some flags it will run in browser with Pyodide/web workers. I should be able to serve this right off the transceiver itself by making some firmware modifications.

So for some use cases I've figured out the single board setup but for people serving public infrastructure to multiple people they will need to wait a bit as I'll have to devise something clever for multi-user setup authentication. I have some ideas to this end but nothing elegant yet. Maybe certain nodes can provide cryptography operations hmm.

React JS

Component-Based Architecture:

React applications are built using components, which are reusable, self-contained pieces of the UI. Components can be nested, managed, and handled independently, leading to better maintainability and scalability.

JSX (JavaScript XML):

React uses JSX, a syntax extension that allows HTML to be written within JavaScript. This makes the code more readable and easier to write.

Virtual DOM:

React maintains a virtual DOM, an in-memory representation of the actual DOM. When the state of an object changes, React updates the virtual DOM and efficiently determines the minimal set of changes needed to update the real DOM, leading to performance improvements.

One-Way Data Binding:

Data flows in one direction, from parent to child components, which makes the data flow and logic easier to understand and debug.

State Management:

React components can maintain internal state, making it easy to build dynamic and interactive UIs. For more complex state management, libraries like Redux or Context API can be used.

Advantages of Using React

Performance:

Due to the virtual DOM, React minimizes direct manipulation of the DOM, resulting in better performance for dynamic applications.

Reusable Components:

Components can be reused across different parts of an application, reducing the amount of code and enhancing consistency.

Strong Community and Ecosystem:

A large community and a rich ecosystem of tools and libraries support React, making it easier to find solutions, get support, and integrate with other technologies.

SEO Friendly:

React can be rendered on the server using Node.js, making web pages more SEO-friendly compared to traditional client-side rendering.

Getting Started with React

To start building applications with React, you need to have Node.js and npm (Node Package Manager) installed. Here’s a basic setup to create a new React application:

Install Node.js and npm:

Download and install from Node.js website.

Create a New React Application:

You can use Create React App, an officially supported way to create single-page React applications with no configuration required:

npx create-react-app my-app cd my-app npm start

import React from 'react';

function Welcome(props) { return

Hello, {props.name}

; }

export default Welcome;

Scaling Secrets: The Architecture That Made 1 Million Users Possible.

Picture this: you launch an app, thinking it'll be a cool side project. But then, something unexpected happens—boom, a viral post, a feature takes off, and suddenly, you're not just handling a few hundred users… you're scrambling to manage 1 million.

It’s every startup’s dream, right? But when reality hits, it's more like a nightmare.

How do you keep your app running smoothly as it rockets to 1 million users? Is there a magic formula, or are you just riding on sheer luck? Spoiler: It’s the architecture—the unsung hero of scaling that most people never talk about.

Let’s dive into the secret sauce that makes all that user growth possible without your app crumbling into oblivion. Trust us, it’s not as simple as throwing money at servers. This is how the pros do it.

Choosing the Right Tech Stack: Building a House with Strong Foundations Okay, first things first: Tech stack matters. Like, a lot. You wouldn't try to build a skyscraper on sand, right? So why would you choose a tech stack that can't handle the weight of millions of users?

The magic happens when you combine the right tools, like a killer backend framework and a database that grows with you.

Backend Frameworks like Node js or Go are the go-to for handling tons of requests. They’re built for speed and efficiency—perfect for a fast-growing app.

For databases, you’ve got to pick wisely. NoSQL (think MongoDB or Cassandra) can handle huge amounts of unstructured data, while SQL (like PostgreSQL or MySQL) is your best friend if you need relationships and transactions in your data.

Caching with tools like Redis or Memcached? A must. Speeding things up by storing frequently accessed data right where it’s needed is a game changer.

Pro Tip: Always choose a tech stack that can scale horizontally, meaning you can add more servers as you grow, rather than upgrading a single, overworked one. (That’s vertical scaling—it's not ideal.)

Horizontal Scaling: More Servers, More Power, No Drama When your app starts attracting millions of users, you’ll quickly discover that vertical scaling—just adding more juice to a single server—doesn’t cut it. It’s like trying to get 10,000 people into a restaurant that only has 10 tables.

Horizontal scaling is where the magic happens. You add more servers to handle the load. It’s like spreading out your resources instead of cramming them into one spot.

Here’s how it works:

A load balancer (like HAProxy or Nginx) distributes the traffic evenly across servers, so no single server crashes from a flood of traffic.

With auto-scaling, your system can automatically add or remove servers based on demand. Got a huge spike in traffic? The system scales up. A quieter day? It scales down. Simple, smart, and flexible.

Outcome: Your app keeps running fast, even when things get crazy.

Sharding: Breaking Up Your Database So It Doesn’t Break You As your app grows, your database grows with it. But here’s the thing: Databases can’t just keep growing forever. At some point, they get too big to handle efficiently. So, how do you keep things running smoothly?

Enter sharding. Think of it like slicing a giant cake into manageable pieces. Instead of storing everything on one massive database, you break it down into smaller, more manageable chunks (called shards).

This way, no one shard gets overloaded. Requests are distributed across multiple database instances, which dramatically speeds things up.

Pro Tip: You can shard your database by horizontal partitioning (e.g., splitting it based on user regions or data types). This reduces database bottlenecks and keeps everything running smoothly.

Microservices: Because One Big App Is a Disaster Waiting to Happen Remember when apps used to be monolithic? Everything was packed into one giant codebase, and you couldn’t change anything without breaking the whole thing. It was a developer's nightmare, and it didn’t scale.

Instead of trying to make one giant app work for everyone, microservices break your app down into smaller, independent pieces. Each microservice does one thing really well, and you can scale those individual pieces separately.

For example, you can have separate services for:

User authentication

Payments

Notifications

Search

These can all run independently, and you can scale them up or down based on specific needs. No more overloading the entire app when just one piece needs more power.

Pro Tip: Use API gateways to handle communication between your microservices and route traffic where it needs to go. This keeps things organized and efficient.

CDNs: Because Speed Kills (In a Good Way) Speed is everything when you’ve got millions of users. Think about it: If your app’s taking more than a few seconds to load, users will bounce faster than you can say “goodbye.” So, how do you speed things up? The answer is simple: CDNs (Content Delivery Networks).

A CDN caches static content (like images, CSS files, and scripts) on multiple servers around the world. So, no matter where your users are, they’re always getting content from the closest server to them. Faster load times = happy users.

Pro Tip: Use Cloudflare or AWS CloudFront to distribute your static assets. This also reduces the load on your primary servers, leaving more resources for dynamic content.

Asynchronous Processing: Don’t Make Your Users Wait Nobody likes waiting. So when your app has background tasks (like sending emails, processing payments, or generating reports), don’t make your users wait around for them to finish.

Instead of handling these tasks synchronously (i.e., right during the user’s request), you process them asynchronously in the background.

This keeps your app responsive, letting users go about their business while those tasks run in the background.

How it works:

Use message queues (like RabbitMQ or Kafka) to send tasks to a queue.

Then, set up worker processes to pull tasks from the queue and process them at their own pace.

Outcome: Your app is faster and more responsive, which means a better experience for your users.

Proactive Monitoring: Because You Don’t Want to Be Caught Off Guard Here’s a brutal truth: things will break. It’s not if—it’s when. The key is to catch issues early before they cause a domino effect of failures.

Proactive monitoring with tools like Prometheus, Datadog, or New Relic keeps an eye on your app’s health in real-time. You’ll get alerts for anything that seems off—like a spike in response times or a server that’s about to crash—so you can fix it before it affects users.

Pro Tip: Set up alerting systems that notify you about potential issues (e.g., high traffic, slow queries). This lets you scale or fix things on the fly.

Failover and Redundancy: Plan for the Worst, Hope for the Best A million users means that even a single point of failure can cause major issues. That’s why you need redundancy and failover built into your architecture. Think of it like a safety net.

Have multiple data centers in different locations.

Replicate your databases and services to ensure that if one fails, the others can pick up the slack.

Use health checks to automatically route traffic to healthy servers.

Outcome: Your app stays up and running 24/7—even if something goes wrong. Users stay happy, and you sleep easy.

The Million-User Blueprint: Scale Smart, Scale Right Getting to 1 million users isn’t magic. It’s a combination of smart design, the right tech stack, and the architecture that lets you scale gracefully. Horizontal scaling, microservices, sharding, CDNs, and asynchronous processing are just a few of the building blocks that power apps with massive user bases.

So, the next time your app goes viral, don’t panic. Instead, focus on scaling smart with these strategies. Because handling 1 million users doesn’t just require hard work—it requires building the right foundation from the start.

Ready to scale? Let’s get building! 🚀

my-first-react-app

Then start the app:

Your first React application will launch in your browser at http://localhost:3000.

Understanding the Basics of React

Now that you have your environment set up, let’s understand key React concepts:

1. Components

React apps are made up of components. Each component is a JavaScript function or class that returns HTML (JSX).

function Welcome() { return <h1>Hello, React Beginner!</h1>; }

2. JSX (JavaScript XML)

JSX lets you write HTML inside JavaScript. It’s not mandatory, but it makes code easier to write and understand.

const element = <h1>Hello, World!</h1>;

3. Props

Props (short for properties) allow you to pass data from one component to another.

function Welcome(props) { return <h1>Hello, {props.name}</h1>; }

4. State

State lets you track and manage data within a component.

import React, { useState } from 'react'; function Counter() { const [count, setCount] = useState(0); return ( <div> <p>You clicked {count} times.</p> <button onClick={() => setCount(count + 1)}>Click me</button> </div> ); }

Building Your First React App

Let’s create a simple React app — a counter.

Open the App.js file.

Replace the existing code with the following:

import React, { useState } from 'react'; function App() { const [count, setCount] = useState(0); return ( <div style={{ textAlign: 'center', marginTop: '50px' }}> <h1>Simple Counter App</h1> <p>You clicked {count} times</p> <button onClick={() => setCount(count + 1)}>Click Me</button> </div> ); } export default App;

Save the file, and see your app live on the browser.

Congratulations—you’ve just built your first interactive React app!

Where to Go Next?

After mastering the basics, explore the following:

React Router: For navigation between pages

useEffect Hook: For side effects like API calls

Forms and Input Handling

API Integration using fetch or axios

Styling (CSS Modules, Styled Components, Tailwind CSS)

Context API or Redux for state management

Deploying your app on platforms like Netlify or Vercel

Practice Projects for Beginners

Here are some simple projects to strengthen your skills:

Todo App

Weather App using an API

Digital Clock

Calculator

Random Quote Generator

These will help you apply the concepts you've learned and build your portfolio.

Final Thoughts

This “Start Coding Today: Learn React JS for Beginners” guide is your entry point into the world of modern web development. React is beginner-friendly yet powerful enough to build complex applications. With practice, patience, and curiosity, you'll move from writing your first “Hello, World!” to deploying full-featured web apps.

Dev Log Apr 25 - Spring Cleaning

New modes means new menus. And that means I get to talk about some programming and architectural stuff again. Quick recap - Crescent Roll is written in Javascript, pretty much 'from scratch' at this point. We used Phaser3 there for a bit, but then I recently tore that out to just do WebGL directly, so the only third-party piece is the wall collision through MatterJS. The 'engine' of the game is actually a series of specific libraries that we wrote for specific pieces, each with their own little codename and interactions. The root part of our system is something we call Plinth - it's a data contract declaration library that adds a little bit of spice to standard JSON and lets you do things like link to other files, copy and re-use declarations of objects, unpack arrays into vectors, specify equations for values, and, most importantly, blend overlapping data from multiple sources to support modding. It's extremely powerful and highly flexible, but also built to my personal preferences. So, you know - it probably doesn't make sense to anyone else. But it makes coding quite the breeze for me. The graphics system is known as Plaster. It's built around the idea of being able to toss one of the Plinth contracts for different objects, and then the display scene can be built from it. Here's a sample snippet from the Level Select on the Main Menu:

(I do want to note that these menu layouts will eventually be made public for editing via the modding kit, but not quite yet, so some of this is probably going to change). This whole thing is very similar to Godot's system, except instead of the nodes driving the program, the program pulls the nodes for data. You can't use Crescent Roll as a general-purpose game engine. So, I guess the closest analog is kind of like a more matured version of the Data Packs in Minecraft. This current system does have a bit of a weakness when it comes to dealing with User Interface stuff. (Which, looking at the most popular JS frameworks, I would say is also probably the biggest issue in the industry, period.) Making the button that moves when you mouse over it is no problem - it's whenever you click on it and now the text for showing the current clear times needs to switch for the next world that we start to hit issues. Our idea for handling the interactions was the concept of 'binding' to specific tags on the objects defined in the JSON, and then whenever those objects were defined or interacted with or an action was to be executed on a particular binding type, code would automatically run to handle whatever the binding was. However, our current implementation for that is a little, we'll say lopsided? I suppose. Bindings all have to be defined before the objects are loaded in to avoid having to re-search everything single sprite every time. Changing hierarchy at runtime would trigger a re-calculation of the binds, which was usually extra wasted work. The different types had to be pre-defined to a code type, so you couldn't decide to just inject an extra description text into one particular type of button with a special binding without doing it to all of them. I wouldn't call it an outright mess, but compared to the other systems, it's not quite up to par. After a bit of pondering, we've decided that the reason it wasn't so great was that it was trying to solve two problems at once. The first being, of course, triggering things to happen to other things in code. However, the second thing was injecting data from higher up into lower below (like setting icons and text when trying to re-use a button). Which that second issue, we realized that it was already accidentally solvable a different way - Plinth already had re-usable object prototyping. Why not just make those work for things other than objects? Plinth has several special fields that you can declare to do specific things. "*" lets you inject whole files as if they were inline, which is the basis for re-using multiple buttons and other controls in other spots. The At Symbol (don't want to accidentally tag somebody here) lets you define sub-objects, and you can inject those values by referring to the tag in a string value. So, we just made it so that you can just define strings and numbers for those, and then made them work cross-file, and presto:

The button would get the defined icon field from the one in the menu that refers to it. Previously, the iconImage would have required a "bind:icon" extra field in it, and then the buttonA in the menu would have a field "icon:ButtonAIcon.json" What about when the icon needs to change from code? Well, there's some transformation that happens when reading from the json into actual graphics objects, and the tags themselves are lost when they're resolved. Even if we did keep them, it would turn into the same kind of tracking done for the bindings to avoid needing to scan potentially hundreds of children on every click. So, in the spirit of KISS, we're currently experimenting with just having a generic "tags" field that is a string:string object that you just stick the name of the binding would have been to point to the object at the top-level menu, and so far it's kind of working surprisingly well. I anticipated needing to daisy-chain to things like button icons, but you never really need to ever touch a pre-existing button, and any created ones will just have direct access through their own tags anyway. The only real downside is that if you want to do both replacement in json and replacement in code, you need both annotations at the same time, but it actually hasn't come up once so far. But hey - adding the times to the level select button was a breeze. So I'll trade off that little bit of elegance for a lot more velocity.

Getting Started with Blockchain Application Development

Blockchain technology is transforming industries by providing a secure, transparent, and decentralized way to record transactions. As the demand for blockchain applications increases, developers are presented with new opportunities to create innovative solutions. In this post, we’ll explore the fundamentals of blockchain application development and how you can get started building your own dApps.

What is Blockchain?

Blockchain is a distributed ledger technology that records transactions across multiple computers in a way that ensures the security and transparency of data. Each block in the chain contains a list of transactions, and once a block is added to the chain, it cannot be altered without consensus from the network.

Key Features of Blockchain

Decentralization: No central authority; data is distributed across a network of nodes.

Transparency: All transactions are visible to participants, ensuring accountability.

Security: Cryptographic techniques secure data, making it difficult to tamper with.

Immutability: Once recorded, transactions cannot be changed or deleted.

Common Blockchain Platforms

Ethereum: The most popular platform for building decentralized applications (dApps) using smart contracts.

Hyperledger Fabric: A permissioned blockchain framework for enterprise solutions.

Binance Smart Chain: A blockchain network running smart contract-based applications.

Solana: Known for its high throughput and low transaction costs, suitable for scalable dApps.

Cardano: A blockchain platform focused on sustainability and scalability through a layered architecture.

Understanding Smart Contracts

Smart contracts are self-executing contracts with the terms directly written into code. They automatically execute actions when predefined conditions are met, eliminating the need for intermediaries. Smart contracts are primarily used on platforms like Ethereum.

Example of a Simple Smart Contract (Solidity)

pragma solidity ^0.8.0; contract SimpleStorage { uint public storedData; function set(uint x) public { storedData = x; } function get() public view returns (uint) { return storedData; } }

Building Your First dApp

Set Up Your Development Environment:

Install Node.js and npm.

Use frameworks like Truffle or Hardhat for development.

Install a wallet like MetaMask for interacting with the blockchain.

Write a Smart Contract: Use Solidity to define the contract's logic.

Deploy the Contract: Deploy to a test network (e.g., Rinkeby, Kovan) using tools like Remix.

Create a Frontend: Use libraries like web3.js or ethers.js to interact with the smart contract from a web application.

Test and Iterate: Test your dApp thoroughly on test networks before deploying to the mainnet.

Best Practices for Blockchain Development

Write modular, reusable, and easily understandable code for smart contracts.

Implement proper error handling and validation to prevent vulnerabilities.

Conduct thorough testing, including unit tests and integration tests.

Stay updated with the latest security practices and common vulnerabilities (e.g., reentrancy, overflow).

Utilize code audit tools to review your smart contracts before deployment.

Conclusion

Blockchain application development offers exciting opportunities to create decentralized solutions that can change the way we interact and transact online. By understanding the basics of blockchain, smart contracts, and development tools, you can begin your journey into this innovative field. Start small, experiment, and build your way up to more complex dApps!
