An API Developer focuses on designing, developing, and maintaining RESTful or GraphQL APIs for applications. Responsibilities include handling CRUD operations, validating requests, and managing data exchange between servers and clients. API Developers implement authentication, authorization, and performance optimization for APIs. Their work allows applications to communicate efficiently and securely with external services or front-end applications.
- Node.js Developer :
A Node.js Developer leverages Express JS to build fast, event-driven, and scalable server-side applications. Tasks include developing server logic, managing routes, and integrating databases with Mongoose or other ORMs. Node.js Developers also implement asynchronous programming and error handling to ensure application reliability. They focus on creating backend systems that support high-performance web applications.
- MEAN Stack Developer :
A MEAN Stack Developer works with MongoDB, Express JS, Angular, and Node.js to develop full-stack JavaScript applications. Responsibilities include designing backend APIs, integrating front-end frameworks, and managing data flow between server and client. MEAN Stack Developers optimize server performance and maintain application security. They ensure cohesive and fully functional web applications across both backend and frontend.
Popular Tools Taught in Express JS Certification Training
- Node.js :
Node.js is the runtime environment that allows Express JS to run on the server. It uses JavaScript for backend development, making it easier for developers to write both client-side and server-side code. Node.js is lightweight, fast, and supports asynchronous programming, which helps in handling multiple tasks at the same time. It forms the foundation for building scalable Express JS applications.
- MongoDB :
MongoDB is a popular NoSQL database used with Express JS for storing and managing data. It allows developers to save information in flexible, JSON-like documents rather than tables. MongoDB works well with Node.js and Express JS, making it easy to retrieve and update data. It is suitable for applications that require high performance and large-scale data handling.
- Postman :
Postman is a tool used for testing APIs created with Express JS. Developers can send HTTP requests like GET, POST, PUT, and DELETE to check if the backend is working correctly. Postman also helps in testing authentication, error handling, and data responses without needing a front-end application. It simplifies debugging and ensures the APIs work as expected.
- Nodemon :
Nodemon is a utility that automatically restarts the Express JS server whenever changes are made in the code. This saves time by avoiding manual restarts during development. It helps developers test and debug applications more efficiently. Nodemon is simple to use and makes the coding workflow smoother and faster.
- Mongoose :
Mongoose is an Object Data Modeling (ODM) library used with MongoDB and Express JS. It helps define schemas for database collections and makes it easy to interact with MongoDB using JavaScript. Mongoose handles data validation, querying, and relationships between collections. This simplifies database management and improves backend development efficiency.
- EJS (Embedded JavaScript Templates) :
EJS is a template engine used with Express JS to create dynamic HTML pages. It allows developers to embed JavaScript code into HTML for rendering data on web pages. EJS makes it easy to generate views based on server-side data, like user profiles or product listings. It helps build interactive and responsive web applications efficiently.
Essential Skills You’ll Learn in a Express JS Course
- Backend Development with Express JS :
This skill teaches how to build server-side applications using Express JS. It includes handling requests, managing routes, and creating APIs that allow front-end and back-end communication.
