Are you interested in a career as a MERN Stack Developer but need to see how to start preparing for it? We have you covered!
MERN (MongoDB, Express, React, and Node.js.) is one of the most widely used web development stacks today, consisting of four powerful technologies that work together to create dynamic and interactive web applications.
In this article, we discuss what MERN Stack developers need to know and learn as new or exploring programmers. Without further ado, here is a list of things that every developer should know: These are basic skills that will serve you for a long time.
- Proficiency in creating structured, semantically correct HTML and styling with CSS.
- Technically, HTML/CSS is not a programming language. It is a markup language used to present user interfaces to web users. The markup language is human-readable and uses tags to distinguish elements in a document. When these tags are included in a document, the computer interprets them and displays the content according to the tag’s instructions.
- In-depth knowledge of React components, JSX, props, state, and lifecycle methods.
- Familiarity with React Hooks for state management and side effects.
- Understanding of React Router for handling client-side routing.
- Integration of third-party libraries and components.
Redux (or Context API):
- Ability to manage complex states in React applications using Redux or the Context API.
- MERN stack developers should focus on how to use the Node Package Manager, also known as npm. This tool simplifies managing multiple versions of code and quickly resolves dependency conflicts between different code packages.
- Express.js is a backend framework that runs in Node.js. It helps MERN stack developers design and create a single page.
- Express.js allows MERN Stack developers to organize server-side web applications in a more manageable model-view-controller architecture while remaining lightweight and fast.
- Mastery of Express.js for building RESTful APIs and handling server routes.
- Knowledge of middleware and request/response handling.
- MongoDB is a document-oriented NoSQL database program known for its adaptability. It meets the foremost point-by-point prerequisites at any scale.
- Expertise in MongoDB, including data modelling, CRUD operations, indexing, and aggregation.
- ORM/ODM tools like Mongoose for MongoDB.
- MERN stack developer employs MongoDB to access and analyze tonnes of data in its indexing, ad hoc queries, and real-time aggregation.
API Design and Authentication:
- RESTful API design principles and best practices.
- User authentication and authorization using technologies like JWT or OAuth.
- Effective state management in frontend (React) and backend (Node.js) applications.
- Writing unit and integration tests for both front and back end using tools like Jest, Mocha, or Chai.
- Proficiency in Git for version control, branching, and collaboration
- Using npm or Yarn for managing project dependencies and scripts
SQL database (PostgreSQL, MySQL, etc.):
- Deploying applications to cloud platforms like AWS, Heroku, or Netlify
- Knowledge of server configuration and deployment strategies.
- Docker for containerization of applications and services.
- Techniques for optimizing application performance include lazy loading and code splitting.
