#Node JS server hosting

[lazar-codes]

12/10/2023 || Day 96

I spent 4 hours today building a small program that's essentially a set of flashcards for the words I'm learning in my ASL class. I wanted to simply create a set of flashcards with Quizlet, but apparently the ability to add an image to a card is behind a paywall and I don't want to pay for that, so I decided I'll just create my own little flashcard system. The teacher writes words on the board during the class, and after class we're allowed to take pictures. The thing is, I'm remembering the sign for the corresponding word mostly by where it's written on the board and what other words it's grouped with, rather than remembering the sign for the word directly.

So, I built a little program that'll let me input words into an array, and I can ask the program to give me a random word in that array, and it worked! But then came the harder part; where do I store the data? I learned that you cannot write to a file from the frontend, so having a frontend json file will be no good, and I didn't want to store it in local storage because what if I accidentally delete my local storage? It would be a huge pain to write 100+ words and links to their signs over and over, so after some googling I learned that I'd need a backend so I can write to and append to a json file using Node js. Honestly, that's a little annoying because now I have to have a server running, but that's the only way I can think of to store data. I'm also planning on adding a feature where I can search for a specific word in my little database and it will give me the link to a video or gif of someone signing that word. But first, I gotta find those gifs/videos/pages and add them to the database.

This is also a really private project, and will only be used for personal use to remember ASL, so this won't be posted or hosted anywhere other than my local computer. The most obvious reason is because there are resources made by Deaf people that should be sought out for first. I'm personally just using this program so I don't have to google "ASL sign for XYZ" every time I forget how to sign something

JavaScript Frameworks

Step 1) Polyfill

Most JS frameworks started from a need to create polyfills. A Polyfill is a js script that add features to JavaScript that you expect to be standard across all web browsers. Before the modern era; browsers lacked standardization for many different features between HTML/JS/and CSS (and still do a bit if you're on the bleeding edge of the W3 standards)

Polyfill was how you ensured certain functions were available AND worked the same between browsers.

JQuery is an early Polyfill tool with a lot of extra features added that makes JS quicker and easier to type, and is still in use in most every website to date. This is the core standard of frameworks these days, but many are unhappy with it due to performance reasons AND because plain JS has incorporated many features that were once unique to JQuery.

JQuery still edges out, because of the very small amount of typing used to write a JQuery app vs plain JS; which saves on time and bandwidth for small-scale applications.

Many other frameworks even use JQuery as a base library.

Step 2) Encapsulated DOM

Storing data on an element Node starts becoming an issue when you're dealing with multiple elements simultaneously, and need to store data as close as possible to the DOMNode you just grabbed from your HTML, and probably don't want to have to search for it again.

Encapsulation allows you to store your data in an object right next to your element so they're not so far apart.

HTML added the "data-attributes" feature, but that's more of "loading off the hard drive instead of the Memory" situation, where it's convenient, but slow if you need to do it multiple times.

Encapsulation also allows for promise style coding, and functional coding. I forgot the exact terminology used,but it's where your scripting is designed around calling many different functions back-to-back instead of manipulating variables and doing loops manually.

Step 3) Optimization

Many frameworks do a lot of heavy lifting when it comes to caching frequently used DOM calls, among other data tools, DOM traversal, and provides standardization for commonly used programming patterns so that you don't have to learn a new one Everytime you join a new project. (you will still have to learn a new one if you join a new project.)

These optimizations are to reduce reflowing/redrawing the page, and to reduce the plain JS calls that are performance reductive. A lot of these optimatizations done, however, I would suspect should just be built into the core JS engine.

(Yes I know it's vanilla JS, I don't know why plain is synonymous with Vanilla, but it feels weird to use vanilla instead of plain.)

Step 4) Custom Element and component development

This was a tool to put XML tags or custom HTML tags on Page that used specific rules to create controls that weren't inherent to the HTML standard. It also helped linked multiple input and other data components together so that the data is centrally located and easy to send from page to page or page to server.

Step 5) Back-end development

This actually started with frameworks like PHP, ASP, JSP, and eventually resulted in Node.JS. these were ways to dynamically generate a webpage on the server in order to host it to the user. (I have not seen a truly dynamic webpage to this day, however, and I suspect a lot of the optimization work is actually being lost simply by programmers being over reliant on frameworks doing the work for them. I have made this mistake. That's how I know.)

The backend then becomes disjointed from front-end development because of the multitude of different languages, hence Node.JS. which creates a way to do server-side scripting in the same JavaScript that front-end developers were more familiar with.

React.JS and Angular 2.0 are more of back end frameworks used to generate dynamic web-page without relying on the User environment to perform secure transactions.

Step 6) use "Framework" as a catch-all while meaning none of these;

Polyfill isn't really needed as much anymore unless your target demographic is an impoverished nation using hack-ware and windows 95 PCs. (And even then, they could possible install Linux which can use modern lightweight browsers...)

Encapsulation is still needed, as well as libraries that perform commonly used calculations and tasks, I would argue that libraries aren't going anywhere. I would also argue that some frameworks are just bloat ware.

One Framework I was researching ( I won't name names here) was simply a remapping of commands from a Canvas Context to an encapsulated element, and nothing more. There was literally more comments than code. And by more comments, I mean several pages of documentation per 3 lines of code.

Custom Components go hand in hand with encapsulation, but I suspect that there's a bit more than is necessary with these pieces of frameworks, especially on the front end. Tho... If it saves a lot of repetition, who am I to complain?

Back-end development is where things get hairy, everything communicates through HTTP and on the front end the AJAX interface. On the back end? There's two ways data is given, either through a non-html returning web call, *or* through functions that do a lot of heavy lifting for you already.

Which obfuscates how the data is used.

But I haven't really found a bad use of either method. But again; I suspect many things about performance impacts that I can't prove. Specifically because the tools in use are already widely accepted and used.

But since I'm a lightweight reductionist when it comes to coding. (Except when I'm not because use-cases exist) I can't help but think most every framework work, both front-end and Back-end suffers from a lot of bloat.

And that bloat makes it hard to select which framework would be the match for the project you're working on. And because of that; you could find yourself at the tail end of a development cycle realizing; You're going to have to maintain this as is, in the exact wrong solution that does not fit the scope of the project in anyway.

Well. That's what junior developers are for anyway...

The Scaling with Node js

In this article, we will discuss the effective scaling practices of developing Node.js web applications. Most Developers are familiar with the Node.js implementation and we will focus on some advanced tactics to scale per the number of users.

Node.js

Node.js is a JavaScript run-time environment built on Chrome’s V8 JavaScript engine; it implements the reactor pattern, a non-blocking, event-driven I/O paradigm. Node.js is well good for building fast, scalable network applications, as it’s capable of handling a huge number of simultaneous requests with high throughput.

The way to improve the scalability

Before entering into the concept, let’s know what is Scalable? A word Scalable refers to expandable, which means the number of users will access the application from anywhere at the same time. Ensure your application is highly scalable; it can handle a large increase in users, workload or transactions without undue strain.

Regarding increasing the scalable, we are going to explain the options for concurrent users.

1. Localhost

Any application that runs on a developer machine for development purpose is hosting application locally. Generally, it is for the use of only one user, so there is no need to worry about scaling factor.

2. Single server

A single server system can accommodate around 1 to 9 concurrent users. Assume, your application will be used locally then the deployment will be carried out locally. It’s fine to do in a single server. For hosting the node.js application one can use Nginx as the webserver.

If you are using a single server application for few users well enough. It is simple to implement the single server and very much efficient for a few users. The requirements consist of only one CPU and 1 GB RAM, which is equivalent to web server AWS t2.micro / t2.nano.

3. Vertical scaling

The term “vertical” states that to manage by adding extra capability or power to a single component. When the server begins to start slower or longer time to execute at the level we will transform to the vertical scaling. In vertical scaling the requirements consist of 4 GB RAM, which is equivalent to web service t2. medium.

The above diagram explains the workflow in the vertical scaling.

a. It consists of two instances of Node.js which runs to deploy/update within zero downtime.

b. The function of Nginx handles the load balance.

c. If server 1 works to upgrade, then the other server keeps serving the requests. Continue this process until the buffer will get empty.

d. The purpose in Nginx takes into account of all the user requests, It consists of two functions such as a static file server and reverses proxy.

Static — The static files like CSS, JS, Images, this will not disturb the web app.

Reverse Proxy — It will access the request for the needs the application to resolve which redirects it.

4. Horizontal scaling

The Scaling horizontally, which means adding more machines to scale up your pool of resources. This concept will work out in the enterprise from the level of 100 to 1000 employees. Whenever the app responses get slowdown from the database you have to upgrade to 16 GB RAM. Cassandra, MongoDB is suitable for horizontal scaling. It provides for implementing a scale from smaller to a bigger machine.

Companies like Google, Facebook, eBay and Amazon are using horizontal scaling.

Differences

In horizontal scaling, you can add more machines to scale dynamically. If any system fails, then another system will handle the process. No worry about the process failing. It will bring high I/O concurrency, reducing the load on existing nodes and improve disk capacity.

In vertical scaling, the data resides on a single node, it gets easy to slow down when the load increases. If the system fails to process, then the whole system may get a collapse. Horizontal scaling is little bit cost-effective than the vertical scaling.

5. Multi-servers

As the business grows, it’s time to add more servers to host the node.js application. The capacity of multi-servers can accommodate above 1000’s of concurrent users. Are you like to transform the previous server to the multi-servers? If Yes, continue with the following steps

1. First, add a load balancer and app units.

2. Set up multiple availability zones (AZ) in a region which one is connected through low latency links.

3. By splitting up the static files for easier maintenance.

4. CDN is one of the servers, which is used to manage files like images, videos, CSS, JS etc.,

Amazon provides load balancing through Elastic Load Balancer (ELB). It is available for the entire availability zone. This service routes to the active host only and can able to manage 1000 instances. By this set up you can use horizontally either vertically.

6. Microservices

Most of the giant companies like Netflix, Uber, Amazon are using microservices. The goals of microservice are to separate the services like search, build, configure and other management functionalities from database instances and deploy them as a separate microservices. Each of these services will take care of their tasks and can communicate with other services via API.

Traditionally we use the monolithic database. In monolithic, we can’t extend our application for several users. All modules are composed together in a single piece. As your business growing up, you have to move on the microservices. This will take to the next level in your production.

Conclusion

Hope this article helped you with scalability issues and helped you understand a bit better of how you can use the available services perfectly.

A Modern Approach to Web Application Development Using MERN Stack

Technology is advancing tremendously quickly right now. With the upgradation of hardware and devices, software technologies are also progressing and replacing outdated ones. Performance is important since a growing number of electronic devices employ real-time features and the Internet. Traditionally, the web development process is supported by technologies with good features but with some limitations that can impact performance. The MERN stack was introduced as a solution to this performance issue and to implement simplicity and uniformity in the development process.

The use of server-rendering technology for web application development was quite popular among developers. While businesses proffered the use of CMS (content management systems) like Drupal and WordPress to build simple websites. The primary advantage of using those CMS was the building speed with minimal coding which was provided by a lot of pre-built templates, themes, and plugins. While it is still preferred by many SMEs, the same properties become a major drawback when enterprises grow and require upgrades or more complex web applications. The pre-built templates proved to be insufficient and as a solution and professionals in the industry begin utilizing the stack of various technologies in web development. Discover more about the MERN stack by reading on or hire the best talent to leverage the MERN stack for your enterprise at WEBSTEP.

What is MERN Stack?

MERN stands for MongoDB, Express, React, and Node. In the stack, MongoDB is the document database, Express(.js) is — Node.js web framework, React(.js) — is a JavaScript library and Node(.js) provides a JS Runtime Environment.

MongoDB: MongoDB is a NoSQL document-oriented database that stores data in a flexible document for scalable high-volume data applications. It has a comparatively faster response and JavaScript interface for testing queries and performing operations with the database.

Express.js: Express is making the development process both simpler and easier. The Node.js framework helps in designing robust APIs with a set of helpful HTTP methods and middleware. It is completely minimalist and has Node features like simplicity, flexibility, scalability and performance.

React: It is a front-end JavaScript library for building user interfaces. One of its major advantages is its capability of handling data-driven interfaces with minimal code.

Node.js: Node is a free open-source web server environment that facilitates the creation of scalable network applications and the execution of JavaScript code outside the browser, on the server.

How to Install Node.js on Linux Using Different Methods?

Node JS is an open-source, back-end Javascript code outside a web browser. Here are the steps on how to install Node.js on Linux using various methods. hire node js develoepr

Node.js is a cross-platform that runs on the V8 engine and executes Javascript code outside a web browser. It also allows developers to use Javascript to write command-line tools and run scripts server-side to produce dynamic web page content before the page is sent to the user’s web browser. 

.js is a standard filename extension for Javascript code, but Node.js doesn’t refer to a file in this context.

Overview of Node.js

Node.js allows the creation of web servers and networking tools using Javascript and modules that handle various core functionalities. Javascript is the only language that Node.js supports natively. As a result, Node.js applications can be written in Clojure script, Dart, and others. It is officially supported on macOS, Linux, and Microsoft Windows 8.1. 

Node.js brings event-driven programming to web servers and allows the development of fast web servers in JavaScript. It connects the ease of a scripting language with the power of Unix network programming. It was built on top of Google’s V8 Javascript engine since it was open-sourced under the BSD license. The Node.js developer community has developed web frameworks to accelerate the development of applications. The frameworks include Socket.IO, Derby, Express.js, Feathers.js, and others. 

Modern desktop IEDs provide debugging features for Node.js applications. These IDEs include JetBrains, Microsoft Visual Studio, or TypeScript with Node definitions. It is supported across several cloud hosting programs like Google Cloud Platform, Joyent, and others.

Install NodeJS on Linux Using NVM

This is the best way to install Node.js. NVM is a bash script used to manage multiple Node.js versions. It allows us to install and uninstall Node.js and switch from one version to another. The best thing is we can install any available Node.js version of our choice using NVM.

Install Node.js on Linux using your distribution’s package manager

It is available in the default repositories of most Linux distributions. If you want to have a stable Node.js on your Linux, you can install it using the distribution package manager.

On Arch Linux and its derivatives like Antergos, Manjaro Linux, run the “$ sudo pacman -S nodejs npm” command to install it. 

On RHEL, CentOS, you need to enable the EPEL repository first. $ sudo yum install epel-release and then install Node.js using $ sudo yum install nodejs npm command.

Exploring the Fundamentals of Node.js

Backend technology and backend languages were covered in our earlier post. We now explore Node.js, the most widely used backend language. We'll walk you through using Node.js to create a basic web server in this post.

 Node.js is an effective runtime environment for server-side JavaScript execution. We will explore the fundamentals of Node.js in this beginner-friendly post. We'll go over its installation procedure, essential features, and architecture.

 Targeted Audience:

 Anybody interested in learning about Node.js, from novices to ambitious developers, should read this article. It requires no prior expertise of server-side coding and only a basic understanding of JavaScript.

 Use Cases:

 Node.js is a flexible framework that is frequently used to create web servers, scalable network applications, real-time programmes like chat rooms, and more. Web developers can benefit from learning Node.js, especially if they want to expand their knowledge of server-side programming.

 Article Composition:

We studied backend technology and backend programming languages in our earlier essay. We will now talk about Node.js, which is the most widely used backend language. This tutorial will walk you through using Node.js to create a basic web server.

Getting Started:

You must have Node.js installed before you can begin constructing a Node.js web server. It should already be operational if you followed our earlier article. If not, you can get it from https://nodejs.org/, the official Node.js website.

Building a Basic Web Server:

 Building a web server is quite simple using Node.js. An exemplary Node.js web server is shown here:

 const http = require('http');

// Define the hostname and port

const hostname = '127.0.0.1';

const port = 3000;

// Create an HTTP server

const server = http.createServer((req, res) => {

  res.statusCode = 200;

  res.setHeader('Content-Type', 'text/plain');

  res.end('Hello, World!\n');

});

// Listen on the specified hostname and port

server.listen(port, hostname, () => {

  console.log(`Server running at http://${hostname}:${port}/`);

});

This code creates an HTTP server that is ready to receive requests, defines a hostname and port, and imports the http module. It says "Hello, World!" in response to a request.

Running Your Server:

Use the node command to launch the code after saving it to a file (such as server.js):

'node server.js'

The IP address of your server is currently http://127.0.0.1:3000/. It is available through your web browser.

We'll look at some of Node.js's more sophisticated features in our upcoming article, such as routing, responding to various kinds of requests, and database interaction. If you build upon this basis, using Node.js to create reliable online applications will come easily to you.

Advantages of Node js:

1)High Performance: JavaScript is natively compiled into native machine code using Google's V8 JavaScript engine, upon which Node.js is based. It is therefore perfect for high-traffic websites and real-time applications because to its remarkable speed and performance.

2)Non-blocking I/O: Node.js employs a non-blocking, event-driven I/O paradigm. This implies that it can manage several connections at once and proceed from one task to the next without waiting for the previous one to complete. This non-blocking feature is essential for applications that need real-time data and high concurrency.

3)Scalability: Developing scalable apps is a good fit for Node.js. Because of its event-driven architecture, which effectively manages many concurrent connections, it's a good option for microservices and applications with demanding scaling requirements.

4)The package manager NPM (Node Package Manager) is included with Node.js and is responsible for hosting a large collection of open-source libraries and modules. This vast network of easily accessible packages streamlines development, saving time and energy.

5)JavaScript All Over: By using Node.js for both the client-side and server-side (front-end) programming languages, programmers may leverage JavaScript across the application stack. Code reusability can be increased and the development process streamlined by unifying the language used.

Limitations of Node js :

1)Single-threaded: Node.js's event-driven, single-threaded approach is useful for effectively managing multiple connections at once, but it isn't appropriate for CPU-bound jobs. CPU-intensive tasks might cause performance bottlenecks by blocking the event loop.

2)Callback Hell: When writing asynchronous code in Node.js, it's common to encounter callback hell, which makes it difficult to read and manage several nested callbacks. This can make it difficult to maintain the code.

3)Absence of Mature Libraries: Although Node.js has a robust library ecosystem, certain sectors, particularly those conventionally linked with alternative programming languages (e.g., scientific computing), might possess a smaller number of well-established libraries.

4)Restricted Support for Multi-core Processing: Due to its single-threaded architecture, Node.js is unable to fully utilise multi-core CPUs. In order to take advantage of multi-core capabilities, developers frequently need to employ extra tools and strategies.

5)Less Safe for Tasks Requiring a CPU: CPU-bound operations are not well suited for Node.js. A CPU-intensive task may cause the event loop to become blocked, which could pose a serious security risk by rendering the server unavailable to incoming requests.

We are grateful that you are interested in learning more about Node.js. Do not hesitate to contact us with any queries or recommendations.

With Node.js, you can do much more than just build a basic web server. As we work through these tutorials, you'll learn more about Node.js and develop your skills in creating server-side apps. Watch this space for more informative insights and fascinating Node.js lessons.

How to Hire the Right node js Developer on Contract: Key Points to Consider

Hiring a skilled, Node.js Developer might be challenging, but it's possible with the correct approach and some planning. We have covered all the bases in this post to ensure a smooth and productive recruiting process for Node JS engineers. So, let us figure out how to round out your team with competent programmers who are a good fit for your project.

For What Reasons Is Investing In A Node.Js Developer The Right Move For Your Company?

Developers skilled in Node.js are essential to the improvement of web apps in terms of both performance and responsiveness. Experienced Node.js developers are in very high demand as organisations strive to expand their online presence. Some outstanding arguments in favour of hire node js developer for your next project are as follows. In-Depth Knowledge Your project is safe in their hands because of their extensive understanding of the ecology. By utilising their abilities, firms may anticipate receiving first-rate web apps crafted to meet the needs of their company and its customers. Incorporating Minimalism Node.js's elegance comes from its ease of use. Hiring experts in this field guarantees a trouble-free development experience. Node.js is an intriguing option for businesses searching for robust but cost-effective online solutions because of its low price and high performance. Web Application Development in Real Time Building real-time online applications like chat programs, gaming servers, or dynamic news feeds is where Node.js excels. These applications are lightweight, practical, and able to handle several simultaneous connections with excellent throughput because of their non-blocking I/O operations. You can leverage this capacity to build dynamic, real-time apps that improve user engagement and provide a contemporary online experience if you have a Node.js developer on staff. Outsource Your Search For A Node.Js Developer In terms of recruiting strategies, outsourcing to an agency may save you both money and time. You may outsource your Node.js development tasks to a proven company using this method. These organisations have teams that have previously collaborated on projects. This saves you time and money by giving you access to a group of highly skilled experts who can do a variety of tasks (design, project management, engineering, etc.).

The contracted firm will tailor a solution based on the details of your project. Each member of the team will sign a separate NDA. Outsourcing organisations may need to learn the ins and outs of their business, which is a drawback. They might be located in a different time zone, adding another factor to consider.

Professional Node JS Developers Make Hosting Easy and Convenient In order to reduce wait times for users of PaaS (platform-as-a-service), this platform regularly adds new features and functionality. This is one of the main draws of Node JS for web development among open-source software development organizations. Effortless Sharing Many web development firms like this Node JS framework over others due in large part to the NPM's (Node Package Manager) ease of sharing. Node JS makes it easy to swiftly distribute data, which speeds up the whole development process. As an example, many Node JS developers use NPM to collaborate on projects by exchanging code and other assets. Additionally, NPM enables simple code management and deployment.

Cost-Effective Node JS reduces the amount of processing power needed to host websites. The multitasking capabilities of Node JS-based programs are well documented. Due to its event-driven and single-threaded architecture, it can handle several requests at once without taxing RAM.

Conclusion

Location, project complexity, developer experience and skill level, and the development firm's approach to hiring all play a role in determining the compensation range for Node.js developers.

ASPX, PHP, Node, CGI-BIN, server side HTML

A quick overview for the novices: server-side scripting isn't new, and there's plenty of ways to avoid browser side scripting, and plenty of solutions that "complete" HTML as a dynamic script.

These scripts do work on the server, however, the browser has to wait for every transaction between whatever you create dynamically. It makes a new http call every transaction.

They don't really help the device do what browser side js can do, because it has to download the exchange every time. Plus, the cost to the host to support it is increased exponentially for every user that you need to support simultaneously.

What they are bad at: doing things on the user side like animations, interactions, or anything that doesn't explicitly require talking to the server about.

What they are good at: anything that requires server side interactions: storing information that needs to be secure, talking with other users, buying things.

If you play a lot switch games, the differences between online play between super smash Bros and Mario kart Best demonstrate the differences.

Mario Kart network interactions are more reliant on user side tweening, which is why there's a lot less frame interruption and why it feels *smoother*.

Super Smash Bros however, needs frame specific interactions on the server (or host side) gameplay. This uses server validation to ensure the player's frames are more or less lined up. And that's why if your connection is unstable, it can feel and look very choppy.

One relys more on user side scripting, one relys more on server side scripting.

This actually happens quite a bit in mobile gaming too. The menus rely heavily on server-side scripting, and it makes them feel heavy, and it's why you wait 3-minutes before the game will let you do anything.

Mobile gaming relies on the RESTful API, which is the standard HTTP API.

They do this mostly as a security protocol to prohibit hacking and cheating (it's heavier the more micro-transactions that they include)

But since they rely so heavily on server-side scripting, the user-experience is heavily impacted.

It's why balancing between browser and server is incredibly important.

One last thing, many coding standards that have been developed over the years have thumped the importance of server-side scripting, this is kind of an outdated policy.

The reason they do that is so you don't have to guess at what kind of device the user is using. So if you just make all the *hard work* server side, then the user won't be impacted.

However, when you see this used in games created in Unity or Godot, and played on Android and Apple devices, you're forgetting that you're already using the user-side scripting to just... play the game.

Both stores includes a version and device check for certain games (which is funny when you have a device that should support the app but the appstore says you can't)

If a user is using a device incapable of using CSS or JS, for whatever reason, that's one thing, you can make a simple page to cover that need. But most everybody else has a smartphone that's been updated in the last decade or so.

Web Scraping Using Node Js

Web scraping using node js is an automated technique for gathering huge amounts of data from websites. The majority of this data is unstructured in HTML format and is transformed into structured data in a spreadsheet or database so that it can be used in a variety of applications in JSON format.

Web scraping is a method for gathering data from web pages in a variety of ways. These include using online tools, certain APIs, or even creating your own web scraping programmes from scratch. You can use APIs to access the structured data on numerous sizable websites, including Google, Twitter, Facebook, StackOverflow, etc.

The scraper and the crawler are the two tools needed for web scraping.

The crawler is an artificially intelligent machine that searches the internet for the required data by clicking on links.

A scraper is a particular tool created to extract data from a website. Depending on the scale and difficulty of the project, the scraper's architecture may change dramatically to extract data precisely and effectively.

Different types of web scrapers

There are several types of web scrapers, each with its own approach to extracting data from websites. Here are some of the most common types:

Self-built web scrapers: Self-built web scrapers are customized tools created by developers using programming languages such as Python or JavaScript to extract specific data from websites. They can handle complex web scraping tasks and save data in a structured format. They are used for applications like market research, data mining, lead generation, and price monitoring.

Browser extensions web scrapers: These are web scrapers that are installed as browser extensions and can extract data from websites directly from within the browser.

Cloud web scrapers: Cloud web scrapers are web scraping tools that are hosted on cloud servers, allowing users to access and run them from anywhere. They can handle large-scale web scraping tasks and provide scalable computing resources for data processing. Cloud web scrapers can be configured to run automatically and continuously, making them ideal for real-time data monitoring and analysis.

Local web scrapers: Local web scrapers are web scraping tools that are installed and run on a user's local machine. They are ideal for smaller-scale web scraping tasks and provide greater control over the scraping process. Local web scrapers can be programmed to handle more complex scraping tasks and can be customized to suit the user's specific needs.

Why are scrapers mainly used?

Scrapers are mainly used for automated data collection and extraction from websites or other online sources. There are several reasons why scrapers are mainly used for:

Price monitoring:Price monitoring is the practice of regularly tracking and analyzing the prices of products or services offered by competitors or in the market, with the aim of making informed pricing decisions. It involves collecting data on pricing trends and patterns, as well as identifying opportunities for optimization and price adjustments. Price monitoring can help businesses stay competitive, increase sales, and improve profitability.

Market research:Market research is the process of gathering and analyzing data on consumers, competitors, and market trends to inform business decisions. It involves collecting and interpreting data on customer preferences, behavior, and buying patterns, as well as assessing the market size, growth potential, and trends. Market research can help businesses identify opportunities, make informed decisions, and stay competitive.

News Monitoring:News monitoring is the process of tracking news sources for relevant and timely information. It involves collecting, analyzing, and disseminating news and media content to provide insights for decision-making, risk management, and strategic planning. News monitoring can be done manually or with the help of technology and software tools.

Email marketing:Email marketing is a digital marketing strategy that involves sending promotional messages to a group of people via email. Its goal is to build brand awareness, increase sales, and maintain customer loyalty. It can be an effective way to communicate with customers and build relationships with them.

Sentiment analysis:Sentiment analysis is the process of using natural language processing and machine learning techniques to identify and extract subjective information from text. It aims to determine the overall emotional tone of a piece of text, whether positive, negative, or neutral. It is commonly used in social media monitoring, customer service, and market research.

How to scrape the web

Web scraping is the process of extracting data from websites automatically using software tools. The process involves sending a web request to the website and then parsing the HTML response to extract the data.

There are several ways to scrape the web, but here are some general steps to follow:

Identify the target website.

Gather the URLs of the pages from which you wish to pull data.

Send a request to these URLs to obtain the page's HTML.

To locate the data in the HTML, use locators.

Save the data in a structured format, such as a JSON or CSV file.

Examples:-

SEO marketers are the group most likely to be interested in Google searches. They scrape Google search results to compile keyword lists and gather TDK (short for Title, Description, and Keywords: metadata of a web page that shows in the result list and greatly influences the click-through rate) information for SEO optimization strategies.

Another example:- The customer is an eBay seller and diligently scraps data from eBay and other e-commerce marketplaces regularly, building up his own database across time for in-depth market research.

It is not a surprise that Amazon is the most scraped website. Given its vast market position in the e-commerce industry, Amazon's data is the most representative of all market research. It has the largest database.

Two best tools for eCommerce Scraping Without Coding

Octoparse:Octoparse is a web scraping tool that allows users to extract data from websites using a user-friendly graphical interface without the need for coding or programming skills.

Parsehub:Parsehub is a web scraping tool that allows users to extract data from websites using a user-friendly interface and provides various features such as scheduling and integration with other tools. It also offers advanced features such as JavaScript rendering and pagination handling.

Web scraping best practices that you should be aware of are:

1. Continuously parse & verify extracted data

Data conversion, also known as data parsing, is the process of converting data from one format to another, such as from HTML to JSON, CSV, or any other format required. Data extraction from web sources must be followed by parsing. This makes it simpler for developers and data scientists to process and use the gathered data.

To make sure the crawler and parser are operating properly, manually check parsed data at regular intervals.

2. Make the appropriate tool selection for your web scraping project

Select the website from which you wish to get data.

Check the source code of the webpage to see the page elements and look for the data you wish to extract.

Write the programme.

The code must be executed to send a connection request to the destination website.

Keep the extracted data in the format you want for further analysis.

Using a pre-built web scraper

There are many open-source and low/no-code pre-built web scrapers available.

3. Check out the website to see if it supports an API

To check if a website supports an API, you can follow these steps:

Look for a section on the website labeled "API" or "Developers". This section may be located in the footer or header of the website.

If you cannot find a dedicated section for the API, try searching for keywords such as "API documentation" or "API integration" in the website's search bar.

If you still cannot find information about the API, you can contact the website's support team or customer service to inquire about API availability.

If the website offers an API, look for information on how to access it, such as authentication requirements, API endpoints, and data formats.

Review any API terms of use or documentation to ensure that your intended use of the API complies with their policies and guidelines.

4. Use a headless browser

For example- puppeteer

Web crawling (also known as web scraping or screen scraping) is broadly applied in many fields today. Before a web crawler tool becomes public, it is the magic word for people with no programming skills.

People are continually unable to enter the big data door due to its high threshold. An automated device called a web scraping tool acts as a link between people everywhere and the big enigmatic data.

It stops repetitive tasks like copying and pasting.t

It organizes the retrieved data into well-structured formats, such as Excel, HTML, and CSV, among others.

It saves you time and money because you don’t have to get a professional data analyst.

It is the solution for many people who lack technological abilities, including marketers, dealers, journalists, YouTubers, academics, and many more.

Puppeteer

A Node.js library called Puppeteer offers a high-level API for managing Chrome/Chromium via the DevTools Protocol.

Puppeteer operates in headless mode by default, but it may be set up to run in full (non-headless) Chrome/Chromium.

Note: Headless means a browser without a user interface or “head.” Therefore, the GUI is concealed when the browser is headless. However, the programme will be executed at the backend.

Puppeteer is a Node.js package or module that gives you the ability to perform a variety of web operations automatically, including opening pages, surfing across websites, analyzing javascript, and much more. Chrome and Node.js make it function flawlessly.

A puppeteer can perform the majority of tasks that you may perform manually in the browser!

Here are a few examples to get you started:

Create PDFs and screenshots of the pages.

Crawl a SPA (Single-Page Application) and generate pre-rendered content (i.e. "SSR" (Server-Side Rendering)).

Automate form submission, UI testing, keyboard input, etc.

Develop an automated testing environment utilizing the most recent JavaScript and browser capabilities.

Capture a timeline trace of your website to help diagnose performance issues.

Test Chrome Extensions.

Cheerio

Cheerio is a tool (node package) that is widely used for parsing HTML and XML in Node.

It is a quick, adaptable & lean implementation of core jQuery designed specifically for the server.

Cheerio goes considerably more quickly than Puppeteer.

Difference between Cheerio and Puppeteer

Cheerio is merely a DOM parser that helps in the exploration of unprocessed HTML and XML data. It does not execute any Javascript on the page.

Puppeteer operates a complete browser, runs all Javascript, and handles all XHR requests.

Note: XHR provides the ability to send network requests between the browser and a server.

Conclusion

In conclusion, Node.js empowers programmers in web development to create robust web scrapers for efficient data extraction. Node.js's powerful features and libraries streamline the process of building effective web scrapers. However, it is essential to prioritize legal and ethical considerations when engaging in Node.js web development for web scraping to ensure responsible data extraction practices.
