Discover how the event loop, the heart of node.js, schedules callbacks in a single-threaded environment. Learn how setTimeout, setInterval, and setImmediate interact with loop, and why blocking code blocks it.

Explore how Node.js uses a single thread with an event loop and offloads heavy tasks to a four-thread thread pool to prevent blocking, with file systems and compression as examples.

Explore event driven architecture in Node.js by building a simple example with event emitters, listeners, and callbacks that respond to a connection event.

Install express with npm, create app.js, and require express to build your first express app. Define routes for home, contact, and about using app.get and res.send.

Explore template engines for node.js, focusing on EJS, its embedded JavaScript approach, and why beginners should prefer it over Pug; and learn to install it with npm.

Create an Express app with the ejs template engine, define a /demo route, render a view from the views directory, and pass id and username to the template.

Learn how to order express routes, set a default 404 page for non matching urls, and guide users home with a proper fallback route.

Define dynamic routes in Express using route parameters like /questions/:id/:title and /users/:id/:username, and access them via req.params for rendering content.

Organize your Node.js app with a views directory for templates and a public directory for assets, and configure Express to serve public files and set the view engine.

Learn to render dynamic data with ejs loops in an express app by creating a questions array and displaying titles, users, and votes via a for each loop.

Learn to implement conditional statements in EJS with if and else to display only questions asked by John (case-insensitive) and show others using else blocks.

Implement post requests with Express by reading data from the request body using body-parser. Submit login forms to /login, validate credentials, and redirect to the dashboard.

Build a movie search app with Express and Node.js, fetching results from an API at localhost 3000/search. Explore searching titles like Avengers and viewing API-driven movie details.

Build a movie app by fetching data from a movie api, register for an api key, handle json with node.js and express, and implement a bootstrap search interface.

Design a movie results page UI in a Node.js Express app using Bootstrap cards, displaying title, summary, publish date, votes, and rating, with a results route and future API integration.

Build a dynamic movie app by fetching API data with the request package, parsing JSON, and rendering movie results with title, overview, release date, votes, rating, and posters.

Explore callbacks, promises, and async/await in Node.js to avoid callback hell. Learn simple examples before diving into MongoDB and your next Express projects.

Learn what callback hell is in Node.js, explore nested callbacks and the pyramid of doom, and see why readability and debugging improve with promises and async/await.

Convert callback hell into clean code by using promises in Node.js; create read file promises, chain then and catch, and replace nested callbacks with promise-based requests.

Master async/await in node.js to replace callbacks, keep the event loop unblocked, and manage promises with try-catch for robust, non-blocking requests and file reads.

Learn MongoDB, a cross-platform document-oriented database known for high performance and scalability. Understand collections and documents with dynamic schemas, bson, and its role in Node.js and MEAN/MERN stacks.
