Complete Node.js Developer 2026: APIs, Projects & Deployment

Explore the global object, process, and buffers in node.js to manage environment variables, input/output, and binary data. Learn to use __dirname, __filename, and process.argv for paths and command line arguments.

Explore handling asynchronous operations in Node.js with callbacks, including setTimeout and fs.readFile examples, and understand callback hell and how promises offer a cleaner alternative.

Explains CommonJS and ES modules in Node.js, showing how to export and import, and compares synchronous loading and performance, including mjs extensions and package.json type module.

Explore built-in Node.js modules such as fs for reading and writing files, path for cross-platform paths, and http to create a simple web server without extra installation.

Learn how to convert callback based functions to promises with util.promisify, then use async/await to cleanly read files and handle errors.

Build a simple http server in Node.js using the built-in http module and http.createServer, handling requests and responses on port 3000 and running locally.

Learn how middleware functions in Express process requests before routing, enabling logging, authentication, and error handling; implement a global logger with app.use and run a Node.js server on port 3000.

Set up an ExpressJS server, install Express, create app.js, define routes with app.get for homepage, bot page, and contact page, and start listening on port 3000.

Learn to handle get, post, put, and delete requests with express.js by setting up routes, parsing json bodies, and performing create, read, update, and delete operations on an item list.

Learn to implement json web token based authentication in node.js using express, generating a token on login, and protecting routes with a verification middleware to secure access.

Hash passwords before storing them to protect user data, using bcrypt to hash and verify passwords with a salt round, and compare input to the stored hash during login.

Implement google oauth in a node.js app using express and passport.js. Enable social login, sign in with google, retrieve basic profile information, and securely manage sessions.

Learn to handle file uploads in an Express.js app using multer, configuring storage, file naming with timestamps, single file routes, and basic error handling.

Learn to handle large file uploads efficiently in Node.js with maltr and streams to process files in chunks. Maintain a responsive server by avoiding loading the entire file into memory.
