When should I choose between Express.js and Node.js?
What is the key difference between Node.js and Express.js?
How do Node.js and Express.js work together?
So I wanted to learn Node.Js thoroughly and recently I’ve been learning Node.js from online tutorial and it seems they are focusing on Node.js with express.js and not Node.js alone. Is it okay to learn it with express? Or should I complete this course and later learn few other things, OR, skip this course and learn only Nodejs??????? (In my company I want to switch internally where they require Node.js developer with some exp.)
The comparison is not entirely correct. The difference between node.js and express.js in the level of abstraction:
- Node.js is a run-time environment for building server-side event-driven i/o application using javascript.
- Express.js is a framework based on node.js for building web-application using principles and approaches of node.js
So, if you write web-application, you can try to use Express.js. In all other cases, it does not suit for you.
Express is built on top of Node, so yes Express adds more features. Node is just a Javascript environment with libraries to make it easy to write software, where Express extends Node specifically to make webservers easy to write.
Express/Connect adds the concept of middleware, a simplified way of managing different routes, automated integration with several templating engines and a bunch more.
Node.js is a JavaScript runtime built on Chrome’s V8 JavaScript engine. It is used to run JavaScript in ways similar to how the browser runs JavaScript but on servers. Express is a library (called a package in the Node.js ecosystem) that makes it really easy to build APIs or serve files.
Node.js is a platform for creating server-side event-driven I/o application using javascript.
Express.js is a framework based on node.js for developing web-application using principles and methods of node.js.
In simpler terms, express.js makes handling API requests and server management easier than using only node.js
