Node.js Vs Laravel: Choosing the Right Web Framework

Difference Between Laravel And Node.Js 

Differences Between Laravel & Node

Language

Node.js: Utilizes JavaScript, a versatile, high-level language that can be used for both client-side and server-side development. This makes the development easy. Laravel: Uses PHP, a server-side scripting language specifically designed for web development. PHP has a rich history and is widely used in traditional web applications.

Architecture

Node.js: It does not enforce a specific architecture, allowing flexibility. Middleware architecture is generally used. Laravel: Adheres to the MVC (Model-View-Controller) architecture, which promotes clear separation of demands and goals, which enhances maintainability and scalability.

Framework

Node.js: Acts as a runtime environment, enabling JavaScript to be executed on the server-side. It is commonly used with frameworks like Express.js. Laravel: A full-featured server-side framework that provides a robust structure and built-in tools for web development, including routing, authentication, and ORM (Object-Relational Mapping).

Strengths

Node.js: Node.js is lightweight and high-performance, using an efficient model to handle many tasks simultaneously, making it ideal for real-time apps and high user concurrency. Additionally, it allows developers to use JavaScript for both frontend and backend, streamlining the development process. Laravel: Laravel provides comprehensive built-in features, including Eloquent ORM, Blade templating, and powerful CLI tools to simplify tasks. It also emphasizes elegant syntax, making the codebase easy to read and maintain.

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.

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...
