Node.js – Build Fast and Scalable Backend Applications

Explore built-in, local, and third-party modules in node.js, including using the fs module to write files, exporting and importing custom utilities, and installing third-party packages with npm.

Explore how the Node.js event loop handles asynchronous operations in a single thread, including setTimeout, fs.readFile non-blocking I/O, and microtasks like promise.then and process.nextTick.

Explore how to work with the file system in Node.js using the built-in fs module, reading, writing, updating, and deleting files with asynchronous examples, error handling, and console output.

Explore how node.js exposes global objects, and use __dirname and __filename for file paths. Access runtime and environment details with the process object, including node version, platform, and memory usage.

Learn to implement non-blocking, event-driven operations in Node.js using callbacks. See practical examples with setTimeout and nested callbacks, and compare to promise-based approaches for cleaner asynchronous code.

Explore es6+ features relevant to node.js, including let and const, arrow functions, template literals, and destructuring to write cleaner, faster code.

Learn to write cleaner, modern JavaScript with arrow functions, let/const, and destructuring in Node.js. See practical examples that show shorter syntax, no unnecessary return, and safer code by avoiding reassignments.

Explore the differences between ES6 modules and common.js, showing export and import patterns, default and named exports, and how to use .mjs and require in Node.js.

Explore npm and package.json to manage dependencies and scripts in a Node.js app. Install axios, configure dependencies and dev dependencies, and run npm start and lint with eslint.

Learn to install and manage nodejs packages with npm, initialize a project, install local and global dependencies like express and nodeman, check outdated packages, and uninstall unused ones.

learn how to manage a node.js project with package.json by installing dependencies like express, adding dev dependencies such as nodemon, and defining start and test scripts to automate tasks.

Install and set up express to build a fast node.js web server with routing, middleware, and modular routes, plus static file serving.

Learn to protect Node.js API routes with middleware, implementing basic authentication and JWT verification to guard dashboards and profile routes.

Define REST as a resource-based, stateless architecture for web applications using HTTP. Represent resources by URL and expose them via standard HTTP methods in JSON, XML, or HTML.

Discover mongodb in node.js as a document-oriented, json-like no sql database with flexible schemas, and features like sharding, replica sets, and fast read and write performance.

Learn to use mongoose, a powerful odm for MongoDB, to connect to a local MongoDB database named user, with new url parser and unified topology, and define schemas and modules.
