Web Development : Mastering MERN Stack

Jsx demonstrates embedding variables with curly braces, using constants for headings, and structuring details for efficient user interface in React.

Learn to implement CSS in React using both traditional CSS and CSS modules, importing App.css or App.module.css and using imported styles as objects like styles.apple and styles.meme.

Explore conditional rendering in react using if/else and the ternary operator to output adult or child. Apply the approach to inline styles and colors with object syntax and curly braces.

Learn to render lists in React using the map function, handle keys and objects, and build reusable components (like user) with props to display names and ages efficiently.

Master React Router, a full-featured library for client- and server-side routing that enables navigation between views in single-page apps, dynamic updates, and defining routes, parameters, and authentication in React apps.

Learn to configure routes with React Router by wrapping the app with BrowserRouter, and define home and contact routes using Route and Routes to create a single-page app.

Learn how to configure routes with React Router, mapping URLs to specific pages in a MERN stack app.

Learn to programmatically navigate in React using the useNavigate hook, moving to a new page on button click and returning to the previous page with ease.

The lecture demonstrates programmatic navigation with the use navigate hook to route from an order button to the order details page and back with navigate(-1).

Build a product page with a search bar, configure nested routes for popular and new products under /product, and render child components via an outlet.

Learn to use the useSearchParams hook to filter users via the url, showing only active users or all users when you reset the filter.

Explore authentication and authorization in a React app. Implement login with a username, protect routes like profile, and redirect unauthenticated users to the login page.

Create a profile page linked in the nav and protect it with an auth context. Implement login/logout and a require-auth wrapper to guard the profile route.

Demonstrate using process.argv to read command line arguments in a node script, showing the node and script paths and provided parameters, then parse with minimist to print the value only.

Master printing outputs in node.js with console.log, format strings with %s and %d, and use console.count, console.trace, console.time, and a progress bar.

Learn Node.js error handling by creating and throwing error objects, building custom errors, and using try-catch, uncaught exception handling, and promise rejection to manage API fetch failures.

Explore manipulating files in node.js using the path module to obtain the directory name, base name, and extension, then join paths for file references (e.g., sample.txt).

Explore node fs file system operations, including reading and writing files asynchronously and synchronously, using promises, path join, encoding, appending data, and renaming files.

Explore Express.js, a Node.js web framework that handles HTTP requests, routing, and middleware to simplify building web apps and APIs with flexible, high-performance back-end architecture.

Learn to build Express middleware—application, router, third-party (Morgan), and built-in (JSON, URL encoded, static)—with error handling, a fake auth flow, and routes for users, plus Multer file uploads.

Implement express with MongoDB CRUD operations by wrapping routes in express-async-handler for automatic error handling, connect via mongoose, define a contact model, and perform create and read operations.

Master user authentication and route protection by building a Mern stack workflow: register, login, current user, and secure endpoints with express routes, mongoose models, and bcrypt-powered password hashing.

Explore implementing jwt-based user authentication in a mern stack, generating access tokens on login, and protecting routes with a token validation middleware tied to mongodb user data.

Build a React-based frontend for a MERN app by scaffolding folders, configuring routing with react-router-dom, and implementing a dynamic users table with create and update forms using Bootstrap.
