Websites currently have come a long way from decade ago when they were framed simply using HTML or CSS. Then next came JavaScript that was able to revolutionize web works. There on, web technologies have seen huge changes, owing to JavaScript frameworks, that made single-page applications .Currently, we’re able to make websites that can retrieve code files from the server once and never, even when visiting other pages.
Chances are if you had thought of becoming a full-stack web developer, you have heard of the term MERN Stack. Maybe you also have considered a MERN stack coding bootcamp.
What is MERN Stack?
MERN stack is web development tech stack similar to MEAN with change of Angular.js that is replaced with React.js. It is beneficial for creating feature-rich single page web applications using JavaScript. Some developers make use it for the popularity and usage of single language for managing both front and back-end of web application.
MongoDB-
It is a NoSQL database for storing data in documents comprising key-value pairs, resemblance to JavaScript Object Notation. It is excellent for :
- Dynamic schemas for models
- High performance through indexing
- Ability to store geospatial data through GeoJSON
- Auto replication
- High scalability via distributing data on multiple servers
In case you are planning to undergo MERN stack bootcamp training you would be learning:
- Setting up MongoDB or cloud MongoDB Atlas database
- Creating models and schemas
- Linking two related models using refs
- Understanding mongoose pre and post hooks
- Perform CRUD operations on database
- Mongoose data validation
ExpressJS- It is the most well-known web application framework that uses NodeJS. In MERN applications, its role is to manage backend API servers, that aids in fetching data from database through React backend.
Areas you would be discovering in this stack through MERN stack coding platform, SynergisticIT are:
- Reading JSON form data sent through front-end via express.json() middleware
- Setting up an ODM such as mongoose with Express
- Setting up express server and listening on desired port
- Separating the logic in different files like controllers,models, and routes.
- Creating custom middlewares for handling errors
- Create endpoints for data CRUD operations
ReactJS- In case you wish to be frontend or ful stack web developer, then you might have heard JavaScript frameworks like Vue, Angular or React. React among these is the most popular JavaScript front-end library. You could create single page applications using React, even for routing it is beneficial. So one can load once and access full website without reloading.
At the best MERN stack bootcamp, SynergisticIT you are in for learning:
- Creating appropriate components and using props
- Creating form inputs controlled and handling form submits
- Deadling with global state via Context API
- Learning use cases of less common React hooks
- Using styled-components in JS methods
- Writing functional React-code
- Managing props in a component through useState hook
- Conditional rendering and using API calls from the useEffect hook to get data from the backend
NodeJS- It is a cross- platform JavaScript runtime environment making use of Google’s V8 engine for running code outside browser. It is made for running on browsers. It allows for writing JavaScript, that could run on backend servers. It V8 engine and libuv for the same.
Here are few concepts you must explore at MERN stack bootcamp:
- Understanding the package.json file
- Initialising a npm package
- Installing npm packages through npm or yarn
- Importing and exports modules using commonJS
- Setting a server with an inbuilt http package
- Accessing the filesystem using inbuilt fs package
Currently, websites make use of MERN for authentication, authorization, restricting access, and state management.
By considering the best MERN stack bootcamp such as SynergisticIT one has chances of improving their career chances.
