Horoscope Generator - Log #3

Y'all, this project's hard. Ran into multiple problems with it but I'm slowly solving them.

Problem 1: How to send information from the backend to the frontend, and get React to display that information once it's received without refreshing the page. I did this using a bunch of useEffect hooks. The first main one is to monitor the status and changes of my userSign variable, which is set once the use clicks on a button corresponding to their zodiac sign.

Doing this sends the sign to the backend, which will then do some magic to get that specific sign's daily horoscope (right now, it's just sending a basic testing message). Now we need to actually tackle the problem where now the backend has data I want to send to the frontend, and again we're gonna use the useEffect hook in React. First thing's first though, we need to send that data, and we do that using Node JS and Express JS. I check to see if there are actual values for both the sign and the resulting horoscope, and if so send it forward.

On the frontend side React will GET the data if both conditions listed below are met, ensuring that I'm only making an API call when I have all the information I need to get a proper answer.

Lastly, the easy part; displaying the message: the App component will check the conditions and if they're met will display the message from the api call.

The other problems I'm running into are more trivial but still super annoying.

Problem 2: Find an api that will give me the daily horoscope for a specific/given sign. All the ones I've found are either paid, or that specific service doesn't work. I actually managed to find a free api that does exactly what I want, but it's only available in Portuguese. Now, I don't speak Portuguese, so this leads into problem 3...

Problem 3: Find a free api that'll translate from a given language to English. I spent a lot of time looking for one and dear god are they hard to find. I managed to find a random one that isn't always 100% accurate, but I'm ok with that. The problem now is that it has a 5,000 character/day limit, so I'll need to come up with a method to simply get all the sign's horoscope for the day and translate it at once, then send it to the frontend to sort through that...

Anyways, those have been my struggles with this project, but here's a small video showing that the information is being sent from the frontend to the backend, and then to the frontend again. In a few days it'll actually have the proper messages, trust me.

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.

What is Express.js? A Comprehensive Guide to Beginners

Let’s start with web development.

When we talk about web development, we are basically essentially talking about the front-end and back-end (also referred to as server-side). Express is a backend development Nodejs framework.

What is a Nodejs Framework?

This section is for those who are not familiar with frameworks. If you already know what a framework is, please feel free to skip ahead.

Writing an application from scratch is time-consuming and tedious, especially in today’s fast-paced world, and initial setup may involve a lot of boilerplate code, such as setting up ports and defining route handlers; frameworks help to save time and effort by providing a pre-built set of tools and libraries that can be used to quickly and easily create a web application. This can free up developers to focus on the things that matter most — writing logic and advanced functionalities.

What is Express js?

The image shows how a tech stack contributes to complete web development. For instance, when it comes to data storage, a Database (e.g., MongoDB) is required, and for writing the front end, various frameworks exist today, such as Angular.js.(in MEAN stack).

Similarly, you need to use a backend-specific language or framework for the backend. Some popular backend languages include Python, Java, JavaScript (Node.js), and PHP, while Django, Express.js, and Flask are some of the popular backend frameworks.

If you want to use JavaScript in the backend, you typically need to use the Node.js runtime environment. Node.js allows you to run JavaScript code outside of a web browser, which makes it possible to use JavaScript for both the front end and back end of a web application.

On top of Nodejs, several frameworks have been created, among which is Express. More precisely, it is a layer built around Node.js that significantly simplifies the process of working within the Node.js environment and reduces development complexity.

Express is an open-source web application framework for Node.js. It provides a robust set of features for building web and mobile applications, including routing, middleware, template engines, seamless database integration, and a wealth of features for developing advanced features and functions.

Note: In this article, when we refer to web applications with Express, we are explicitly referring to the development of “back-end services or APIs.”

Features of Express

1. An array of pre-built tools

The framework includes an array of tools for web applications, routing, and middleware for building and deploying large-scale, enterprise-ready applications.

2. Node package manager

It comes up with a Node package manager and a command-line interface(CLI), allowing you to create project structures, generate routes, controllers, and other components, as well as manage dependencies and configuration settings.

3. Middleware

Middleware in Express is used as snippets of code that intercept requests and responses, manage errors, and perform various other tasks, helping you to perform actions like validation, logging, and authentication in a reusable and modular way.

4. Routing

ExpressJS offers developers a straightforward routing system that simplifies the handling of HTTP requests. In addition, it allows you to define your own special paths and rules for these requests.

Applications of Expressjs

It is termed as a versatile framework that developers employ for constructing APIs, single page and real-time applications, microservices, proxy servers, CMSs, backend for mobile applications, authentication, authorization mechanisms, and many more services. Below is a list of the application you can build using Express js.

1. APIs for Single Page Application

Single-page applications (SPAs) are a popular type of web application that loads all of the content for the page in one go. This means that the user does not have to wait for the page to reload when they interact with it, which can provide a smoother and more responsive experience.

Some popular examples of SPAs include Gmail, Google Maps, and Spotify. These apps are able to provide a great user experience because they only need to load the content once, and then they can dynamically update the content based on the user’s actions. This makes for a very fluid and interactive experience. Express is used for developing back-end services, or APIs, for single-page applications to fetch data.

2. Real-time applications

Real-time applications are increasingly popular as they allow users to interact with each other in real time. Some popular examples of real-time applications include multiplayer games, chat apps, and collaboration tools. Express is used in developing real-time applications.

It helps you build the basic structure, like handling web pages and buttons, and when you want your website to instantly update without needing to refresh the page, Express.js and socket.io can work together.

Express.js can take care of the regular stuff your website needs, like showing pages and handling regular requests. While WebSockets enables real-time data exchange between the server and clients.

3. Streaming applications

Streaming applications are becoming increasingly popular as they allow users to watch movies, TV shows, and other content on demand. Some popular examples of streaming applications include Netflix, Hulu, and Disney+.

You can leverage Express in streaming applications for a variety of tasks, including handling requests, serving media files, developing authentication and authorization modules, implementing search and recommendations, and many more functionalities.

4. Fintech application

Some popular fintech applications that are built with Express.js include Robinhood, Coinbase, and PayPal. Leveraging the robust functionalities of Express.js, these applications efficiently manage intricate financial transactions.

5. APIs

APIs are software intermediaries that allow different systems to communicate with each other. They are widely utilized by different systems for integrating payment gateways, social media integrations, and e-commerce integrations. Brillworks has developed a suite of APIs and applications for the business consulting and media preservation industries, which includes critical functions such as company setup, visa services, corporate services, file management, customer portal, CMS portal, bulk upload, etc.

আজকে কথা বলতে যাচ্ছি জাভাস্ক্রিপ্টে কীভাবে স্কিলড হওয়া যায় এবং কীভাবে শুরু করতে পারি? বা একজন জাভাস্ক্রিপ্ট ডেভেলপারের কী কী জানা প্রয়োজন হতে পারে?

প্রথমে জেনে নেয়া যাক কাভাস্ক্রিপ্ট কি?

জাভাস্ক্রিপ্ট হলো একটি লাইট ওয়েট, ইন্টারপ্রিটেড অথবা জাস্ট-ইন-টাইম কম্পাইল্ড প্রোগ্রামিং ল্যাঙ্গুয়েজ। এটা স্ক্রিপ্টিং ল্যাঙ্গুয়েজ হিসেবেও পরিচিত। ব্রাউজারের মাতৃভাষা বলা যেতে পারে এই জাভাস্ক্রিপ্ট কে। আরেকভাবে বলতে গেলে বলা যায়, HTML যদি ওয়েবসাইটের হাড্ডি-গুড্ডি হয় আর CSS যদি ওয়েবসাইটের সাঁজ-সজ্জার সরঞ্জাম হয় তাহলে ওয়েবসাইটের ব্রেইন বলা হবে জাভাস্ক্রিপ্ট কে।

এবার আসি কীভাবে শুরু করতে পারি?

⦿ Understand the basic:

সর্বপ্রথম যে স্টেপ সেটি হলো জাভাস্ক্রিপ্ট এর বেসিক এবং ফান্ডামেন্টালস সম্পর্কে জানা, যেমনঃ ভেরিয়েবল, ডাটা টাইপ, অপারেটর, লুপ, ফাংশন, অ্যারে অবজেক্ট ইত্যাদি। এসব বিষয়গুলোর উপড়ে স্পষ্ট ধারনা থাকা আবশ্যক। বেসিক স্ট্রং না থাকলে খুব একটা সুবিধা করে উঠা সম্ভব না।

⦿ Dive deeper into JavaScript:

বেসিক শেষ করার পড় এবার গভীরে ঢোকার পালা। এই স্টেপ এ জাভাস্ক্রিপ্ট-এর অ্যাডভান্স কিছু বিষয় নিয়ে ঘাটাঘাটি করার সময়। এর মধ্যে আছে clouser, scope, hoisting, prototype-based inheritance। আরও কিছু বিষয় এই স্টেপ এ শিখা উচিত। এগুলোর মধ্যে callbacks, promises, async/await অন্যতম। এছাড়াও ইরোর হ্যান্ডেলিং এবং ডিবাগিং টেকনিক গুলো তো শিখতেই হবে।

⦿ Practice with Hands-on Exercise:

এসকল টপিক ক্লিয়ার করে নিয়ে এবার প্রবলেম সল্ভিং এ প্রবেশ করতে হবে। বিভিন্ন কোডিং চ্যালেঞ্জ এবং এক্সারসাইজ তোমাকে একজন জাভাস্ক্রিপ্ট এর কনসেপ্টগুলোকে পাকাপোক্ত ভাবে বুঝতে সহায়তা করবে।এছাড়াও বিভিন্ন অনলাইন প্ল্যাটফর্ম যেমন FreeCodeCamp বিভিন্ন প্র্যাকটিস প্রবলেম এবং প্রজেক্ট অফার করে। এসকল প্র্যাকটিস প্রবেল্যাম্ব আর প্রজেক্টগুলো করা জ্যাতে পারে। এতে করে জাভাস্ক্রিপ্ট এর ভিত ম��বুত হবে।

⦿ Build Projects:

এবার প্রজেক্ট করার পালা। এতদিন এ যা যা শিখেছো সেসব কে কাজে লাগিয়ে ��ানিয়ে ফেলো ছোট ছোট প্রজেক্ট। এটা হতে পারে ফর্ম ভ্যালিডেশন বা ক্যালকুলেটর। আবার হতে পারে To-Do List অ্যাপ্লিকেশন। তোমার প্রগ্রেস অনুযায়ী আরও কমপ্লেক্স প্রজেক্ট করার চেষ্টা করা উচিত। যে প্রজেক্ট এ API থাকতে পারে, বা হতে পারে ডাটাবেস এর সাথে ইন্টিগ্রেশন। আবার হতে পারে একটি ইন্টার‍্যাক্টিভ ওয়েব অ্যাপ্লিকেশন। প্রজেক্ট না করলে এসবের আসল প্রয়োগ শেখা সম্ভব না। তাই বেশী বেশী প্রজেক্ট করা উচিত।

⦿ Learn DOM Manipulation:

এবার DOM অর্থাৎ Document Object Model নিয়ে খেলা দেখানোর সময়। এই স্টেপ এ JavaScript কীভাবে HTML, CSS এর সাথে ইন্টার‍্যাক্ট করে DOM কী? এটা কীভাবে কাজ করে এই বিষয়গুলো বুঝতে হবে, জানতে হবে। কীভাবে HTML, CSS আর JavaScript মিলে একটা ইন্টার‌্যাক্টিভ ওয়েব অ্যাপ্লিকেশন তৈরি হয় এই বিষয়গুলো বুঝতে হবে। কীভাবে HTML এলিমেন্ট গুলোকে ম্যানিপুলেট করতে হয়, কীভাবে স্টাইল চেইঞ্জ করতে হয়, কীভাবে ইভেন্টস গুলোকে হ্যান্ডেল করতে হয় এই বিষয়গুলো জানতে হবে এবং সব মিলে একটা ইন্টার‍্যাক্টিভ ওয়েবসাইট বানিয়ে ফেলতে হবে।

⦿ Study JavaScript Libraries and Frameworks:

বিভিন্ন জনপ্রিয় জাভাস্কিপ্ট লাইব্রেরিগুলোকে এক্সপ্লোর করতে হবে। এরমধ্যে রয়েছে React, Angular, Veu ইত্যাদি। এগুলোর কোর কনসেপ্ট গুলো বুঝতে হবে। এগুলো ব্যবহার করে কীভাবে আর শক্তিশালী ওয়েব অ্যাপ্লিকেশন বানানো যায় সেই সম্পর্কে জানতে হবে।

⦿ Learn Backend Development with Node Js:

Node Js সম্পর্কে কোর কনসেপ্টগুলো জানতে হবে। এটি একটি জাভাস্ক্রিপ্ট রানটাইম এনভায়রনমেন্ট যা সার্ভার সাইড ডেভেলপমেন্ট এ সহায়তা করে। এরপর Node Js এর পপুলার ফ্রেমওয়ার্ক Express Js দিয়ে কীভাবে ওয়েব সার্ভার, API সমূহ তৈরি করা যায় সেই সব বিষয় শিখতে হবে। ওয়েব সার্ভার শিখতে গেলে ডাটাবেস সম্পর্কে ধারনা থাকা আবশ্যক। এগুলোকে কীভাবে ব্যাকেন্ড এর সাথে ইন্টার‍্যাক্ট করতে হয় সেই সম্পর্কে জানতে হবে। এর জন্য কিছু লাইব্রেরিও রয়েছে যেমন Mongoose, Sequelize ইত্যাদি। এগুলো সম্পর্কে ধারনা রাখতে হবে।

⦿ Keep learning and stay updated:

জাভাস্ক্রিপ্ট এ প্রায়ই নিত্যনতুন আপডেট এর দেখা পাওয়া যায়। তাই সময়ের সাথে নিজেকে আপডেট রাখা খুব জরুরি। নতুন নতুন ফিচার গুলো ফাংশনালিটি গুলো যতদ্রুত আয়ত্ব করে ফেলা সম্ভব ততোই ভালো। এর জন্য ডিকুমেন্টেশন, ইউটিউব টিউটোরিয়াল, ব্লগ ইত্যাদির সাহায্য নেয়া যেতে পারে। জাভাস্ক্রিপ্ট এর বিভিন্ন কমিউনিটি-এর সাথে যুক্ত হওয়া যেতে পারে যেখান থেকে প্রতিনিয়ত আপডেটেড বিষয়গুলো সম্পর্কে জানা সম্ভব।

⦿ Collaborate and Contribute:

ডেভেলপার কমিউনিটি-এর সঙ্গে যুক্ত হয়ে বিভিন্ন ওপেন-সোর্স প্রজেক্ট-এ অংশগ্রহণ করা, বিভিন্ন ডেভেলপারদের সাথে কোলাবরেট করা, বিভিন্ন প্ল্যাটফর্ম এ কন্ট্রিবিউট করা যেমন, GitHub। গিটহাব তোমাকে প্র্যাক্টিক্যাল অভিজ্ঞতা এবং কোডিং স্কিল কে বৃদ্ধি করতে অনেকটাই সাহায্য করবে।

⦿ Build a Portfolio:

শেখার পালা তো শেষ। এবার নিজের স্বপ্নকে ছোঁয়ার সময়। এর জন্য প্রয়োজন হবে একটি স্ট্রং পোর্টফলিও, যেখানে তোমার করা প্রজেক্ট এবং স্কিলসগুলোকে প্রদর্শন করা যায়। সেখানে তোমার গিটহাব পোফাইল / রিপোজিটরি, ডিপ্লয় করা প্রজেক্টসমূহ এবং প্রজেক্টগুলোর বিষদ বর্ণনা থাকতে পারে। তোমার একটি স্ট্রং পোর্টফোলিও তোমার স্বপ্নকে ছুতে অনেক সাহায্য করবে।

সবশেষে, এটাই মনে রাখবে প্র্যাকটিস, প্র্যাকটিস, প্র্যাকটিস। প্র্যাকটিসের বিকল্প কিছুই নেই। প্রতিনিয়ত বিভিন্ন প্রজেক্ট, প্রবলেম সল্ভিং ইত্যাদির মাধ্যমে তোমার প্র্যাকটিস করে যেতে হবে।

Learning JavaScript is an ongoing process, so stay committed, be patient, and enjoy the journey!

Reactjs: document is not defined

I have a pretty simple react project setup:

├── app.js├── components│   ├── MainWrapper.js│   └── html.js├── package.json└── server.js

The application is started by:

node server.js

Which uses the express server and renders markup for an HtmlComponent in html.js:

import React from 'react';import MainWrapper from './MainWrapper.js'class HtmlComponent extends React.Component { render() { return ( <html> <head> <meta charSet="utf-8" /> <title>My Awesome Site</title> <meta name="viewport" content="width=device-width, user-scalable=no" /> <link rel="stylesheet" href="awesome.css" /> </head> <body> <div id="root"></div> </body> </html> ) }}export default HtmlComponent;

The goal is to create a Wrapper that will fill the 'root' div. It's very simple right now:

MainWrapper.js:

import React from 'react';import ReactDOM from 'react-dom';var MainWrapper = React.createClass ({ render: function() { return ( <button>go</button> ) }});React.render(<MainWrapper />, document.getElementById("root"));

When I run node server.js there's an exception:

/Users/me/Desktop/Simple/components/MainWrapper.js:36_react2['default'].render(_react2['default'].createElement(MainWrapper, null), document.getElementById("root")); ^ReferenceError: document is not defined at Object.<anonymous> (/Users/me/Desktop/Simple/components/MainWrapper.js:27:31) at Module._compile (module.js:425:26) at normalLoader (/Users/me/Desktop/Simple/node_modules/babel-core/lib/api/register/node.js:199:5) at Object.require.extensions.(anonymous function) [as .js] (/Users/me/Desktop/Simple/node_modules/babel-core/lib/api/register/node.js:216:7) at Module.load (module.js:356:32) at Function.Module._load (module.js:311:12) at Module.require (module.js:366:17) at require (module.js:385:17) at Object.<anonymous> (/Users/me/Desktop/Simple/components/Html.js:5:26) at Module._compile (module.js:425:26)

I do not understand why document is not defined. It seems it's simple javascript.

MEAN Stack: What and Why

What is MEAN?

MEAN represents MongoDB, Express.js, AngularJS, and Node.js. It is an end-to-end JavaScript used in cloud-ready web applications. It is built to ease the development of web applications and handle JSON.

MEAN stacks have flexibility, and scalability, and their ability to handle concurrent users makes them ideal for cloud hosting. It has its web server that can be deployed quickly and the database can be scaled to accommodate temporary usage spikes.

The MEAN stack comprises four technologies-

MongoDB -An open-source NoSQL database

Express - Forms the backend of MEAN and handles all interactions between the front end and database.

AngularJS - Used to develop the user-facing side of the application. 

Node.js - The open-source JavaScript framework uses asynchronous events to process multiple connections concurrently.

Components of MEAN

Components of the MEAN stack are divided into three categories: frontend, backend, and database.

Frontend

It refers to the front side or the client side of the application. It refers to anything that a user can engage, or interact with on the screen. The purpose of the front end is to create a smooth user interface, user experience, and straightforward internal structure which includes the design, format, and navigation of websites or web apps.

It uses HTML, CSS, and JavaScript languages to design the front portion of the web that includes components like design, theme, styles, functionality, etc. In the MEAN, the AngularJS framework is used.

AngularJS

AngularJS is the open-source JavaScript framework that is used to build single-phase applications and line-of-business applications. It changes static HTML to dynamic HTML and enhances its ability by inserting attributes and elements. It also provides the ability to create custom attributes using JavaScript. It has features like dynamic binding and dependency injection which eliminates the need to write code that was otherwise required to be written.

Backend

It is responsible for storing and organizing data and ensuring the smooth running of operations. If the frontend is the code that runs in the user’s browser, the backend code runs on the server. It receives requests from clients and has the logical knowledge to send appropriate data back to the user. It also includes a built-in database that stores all the information

The APIs built by backend developers can be used by frontend developers for integration of the client-side and server side. Backend can be built using many languages like PHP, Python,, or Java. MEAN stack uses Express and Node.js for the backend.

Express

ExpressJS or Express is a node js web application framework that provides various features for building web and mobile applications. It is used in single-page, multipage and hybrid web application development. Companies using Express are Netflix, uber, eBay, etc.

Node.js

It is an open source cross-platform runtime environment and library used for running web applications. It is used for server-side programming and primarily installed for non-blocking, event-driven servers, such as traditional websites and backend API services.

Node.js is a runtime environment meaning, it contains Web APIs that a developer can access to build a code and a JavaScript engine that parses that code. This makes it lightweight, flexible, and easy to install resulting in optimization and enhanced speed of the project. 

Database

Oracle defines a database as “an organized collection of structured information, or data typically stored electronically in a computer system”. It is controlled by Database Management System (DBMS). Data is typically modeled in rows and columns in a tabular format to make processing and data querying efficient.

There are many types of databases depending upon the need of the organization. Some of the popular categories are- Relational databases, Object-oriented databases, Distributed databases, Open source databases, and Cloud databases to name a few. MEAN uses the NoSQL database program MongoDB.

MongoDB

It is a cross platform, document oriented database that provides high performance, high availability, and easy scalability. It works on the concept of collection and document. Every document in MongoDB is described in BSON, a binary representation of the data. This information can be retrienved in JSON format by applications.

It is a document database, which makes it easy for developers to store structured and unstructured data. It was built on a scale-out architecture that is very popular among all kinds of developers for developing scalable applications with evolving data schemas.

It is best if you want to: enable collaboration of large number of teams, scales to high level of rean and write traffic, scale data repository to massive size, evolve the type of deployment as the business changes, store, manage and search data with text, geospatial or time-series dimensions.

Why MEAN stack is ideal for Web and Mobile Application Development?

As the MEAN stack is based on JavaScript, implementation is easy. Developers can use JS platform to implement MEAN stack application for streamlined app development using a single language across the whole application. 

It is a great support for organization as it is simpler for companies to follow a modern approach by using MEAN. It helps developers in expanding their skillsets to write modern apps.

It enables UI development which offers a user-friendly experience. It support MVC architecture to generate native-type web applications. Node.js is used for non-blocking type I/O and it removes the overload of the request proceeding to improve site speed. Angular is applied to improve code reusability. MEAN support open source frameworks using cloud repositories. mongoDB is also used to deal with cloud usage.

Conclusion

MEAN stack is highly flexible and modern technology that is very popular among developers. All the components are open source in nature, allowing a free of charge and generous opportunity for the developers. Whether you are building a high-throughput API, simple web application or a microservice, MEAN is the optimal choice.
