ExpressJS Course in Jalandhar - Itronix Solutions
ExpressJS is a popular web application framework for NodeJS. It simplifies the process of building web applications and APIs by providing a robust set of features and utilities. ExpressJS allows developers to create web servers, define routes, handle HTTP requests and responses, manage middleware, and much more, with a minimalist and flexible approach. One of its key strengths is its middleware system, which enables the integration of various plugins to handle different aspects of web applications, such as logging, authentication, parsing request bodies, and serving static files. ExpressJS doesn’t impose strict rules, allowing developers to structure their applications according to their preferences. Its simplicity, flexibility, and vast ecosystem of middleware and extensions make it a popular choice for building web applications and APIs using NodeJS. Express uses middleware functions to process incoming requests. These functions have access to the request and response objects and can modify them, execute code, or pass control to the next middleware in the stack. It simplifies handling HTTP methods and status codes, making it easier to send responses, redirect users, or handle errors. Here’s outline for an ExpressJS course:
