Complete Node.js Bootcamp: From Basics to Advanced

Discover how the V8 JavaScript engine powers Node.js by executing JavaScript with just-in-time compilation, optimizing heavy computations, and managing memory through garbage collection.

Learn how Node.js uses an event-driven, non-blocking I/O model to handle many tasks, with non-blocking file reads via callbacks and an event emitter powering a simple HTTP server.

Explore how the Node.js event loop enables non-blocking asynchronous tasks, demonstrating timers with setTimeout and setImmediate, and non-blocking file I/O with fs.readFile and callbacks, including nextTick behavior.

Explore the Node.js fs module for reading and writing files, demonstrating synchronous and asynchronous methods, error handling, and creating output files like example.txt and download.js.

Explore how the path module joins segments, resolves absolute paths, and extracts file information with basename, extname, and dirname for cross‑platform file operations.

Learn to build a basic web server with node's http module, handling requests and responses. Serve json data on localhost port 3000 with an api endpoint.

Learn to parse and format URLs in Node.js using the URL module, extracting protocol, host, hostname, path, and query parameters with URL objects.

Discover how to install and manage npm packages, including globally with npm install -g nodemon and locally within a project, update package.json, and verify installations.

Learn to use npx to run packages from the npm registry without global installation, including creating a react app and running specific package versions directly from the command line.

Explore asynchronous patterns in node.js by implementing callbacks, promises, and async/await with the fs module to read files, handle errors, and compare code readability across approaches.

Explore the asynchronous, non-blocking, event-driven architecture of Node.js using setTimeout to illustrate how callbacks defer to the event loop, enabling multiple tasks without blocking.

Learn to handle errors in asynchronous Node.js code using callbacks with the fs module, including error checks, and contrast with synchronous try-catch and promises.

Explore the event emitter in node.js by importing the events module, creating and emitting custom events, registering multiple listeners with on, and observing event-driven behavior.

Explore how to create and use readable and writable streams in Node.js, including custom streams, the push method, and handling data events for efficient data processing.

Build efficient data pipelines with node streams, transforming data along the way using a transform stream, piping from input text to output text and handling uppercase conversion.

Create a basic HTTP server with Node.js, responding with hello world using the HTTP module and listening on port 3000.

Handle routes and requests in Node.js by building a simple server with the http module, defining the home page and about us page, and returning a 404 for other paths.

Learn to build a simple Node.js HTTP server, send responses and manage headers, including 200 status and 404 not found, set content types, and return text or JSON.

Connect to a local MongoDB instance using the Node.js MongoDB native driver, establish an asynchronous connect flow, handle errors, log success, and close the connection.

Learn how to connect a Node.js application to MySQL and PostgreSQL databases using mysql2 and the PostgreSQL client, with step-by-step setup, configuration, and connection handling.

Learn to efficiently read and write large files in Node.js using streams and the fs module, processing data in chunks with read and write streams.

Create a simple Node.js API with Express, set up a server, and expose a GET endpoint returning a JSON list of items: apple, banana, cherry.

Explore asynchronous patterns in node by implementing file reads with callbacks, promises, and async/await, compare readability and error handling, and learn to avoid callback hell.

Learn to test rest APIs with Postman, create and run collections, write automated tests with pm, export json collections, and use Newman for command line interface execution and CI workflows.
