Full-Stack Web Development with Angular and Express.js

Explore Express.js, the fast Node.js framework for building web apps and RESTful APIs, with routing, middleware, template engines like Ejs or pug, and robust error handling.

Discover why Express.js offers lightweight, unopinionated web development with a minimalistic approach, an intuitive API, strong middleware capabilities, active community, and non-blocking I/O for scalable performance.

Install Node.js and verify the version, then set up an Express.js project with npm init, install express, create index.js, and run with node one to auto restart on changes.

Understand HTTP methods and their purposes: get reads data, post creates, put updates, and delete removes. See how frontend, API endpoints, and database execute CRUD actions in the request cycle.

Configure express in index.js by requiring express, creating an app, and starting a server on port 5000; learn npm scripts and optional import syntax.

Configure an express server in index.js, install express and nodemon, and implement route handlers for get, post, put, and delete on http://localhost:5000 to handle HTTP requests.

Configure express.js routers to handle get, put, post, and delete requests on the home base, then run the server on port 3000 and test responses.

Mount a router at the root route to handle all get, post, put, and delete requests, then test each route on localhost:3000.

Create multiple files to organize routes by domain, separating user routes and post routes in a routes folder, using Express.js routers and an index.js to mount them.

Learn to organize routes by using app.use, separate user and post routes, define base URLs like /users and /posts, handle get and post methods, and export default router.

Learn to extract dynamic route parameters in Express.js by defining routes with a colon, capturing the id from req.params, and returning it.

Explore handling optional and dynamic route parameters in express.js by defining get, post, put, and delete endpoints, using optional ids with req.params.id, and returning dynamic student details.

Learn to handle get, post, put, and delete requests on the home route, log request details in the console, and test endpoints with Thunder Client while the server runs.

Build simple Express endpoints to manage an array with Thunder Client, including get all, get by id, insert, update, and delete, using body parser to access request bodies.

Learn to send http requests using post get and put methods, handle json bodies with body-parser, and update and fetch student data on localhost 3000 via Thunder client.

Practice sending http requests with put, get, and delete methods to update a first index element, fetch all students, and remove the last element using Thunder Client for CRUD.

Send put, get, and delete requests to manage a student list with Thunder client, performing create, read, update, and delete operations on the data.

Explore how Express.js middleware pre-processes requests, validates users, and protects routes, while handling errors and enabling data parsing and modification between client and server.

Master post-processing of responses with a middleware chain, where route handlers generate a response and the next function passes control to subsequent validation and endpoint logic.

Explore error handling middleware with the four-parameter pattern to centralize errors, then enforce route protection via JWT and implement custom middleware, such as a Rahul-name check, for security and modularity.

Write custom middleware in express to gate access for authenticated users by checking req.body.is_auth with next, and protect routes using app.use and body-parser.

Implement route-specific middleware in Express by creating a user route with a router, applying an auth check that uses next to grant access or deny it.

Differentiate built-in and custom middleware in express.js; built-in handles standard tasks like body-parser JSON and URL-encoded data, while custom middleware controls next calls based on headers or body data.

Explore common Express.js error types—syntax, runtime, routing, middleware, and database errors—and master robust error handling with try-catch, error middleware, and custom responses to improve application stability and user experience.

Implement an error middleware in Express to catch errors via the error parameter, log them, set a status code (default 500), and respond with a meaningful message.

Learn to handle errors with try catch blocks in Express.js, using a try block and a catch block, passing errors to next and a middleware to send responses.

Create a root middlewares/errorMiddleware.js to centralize error handling, log errors, and respond with a 500 status. Wire it with app.use in Express so one middleware handles route errors.

Learn to classify and handle common http status codes and errors, from 1xx informational to 2xx success and 3xx redirection, including 200, 400, 404, 500, and craft graceful user messages.

Explore 4xx client-side errors such as 401 unauthorized and 404 not found, and 5xx server errors like 500 internal server error, with error handling using try-catch and rest dot status.

Explore how to integrate a database with Express.js using MongoDB for permanent data storage, CRUD operations, and NoSQL JSON-like storage to optimize data handling.

Connect Express.js to MongoDB using Mongoose, install mongoose, and call mongoose.connect with localhost:27017 and the books db, using URL parser and unified topology to support crud API requests.

Create a books model with a mongoose schema to define fields like book name, issue date, and optional author. Build an Express API endpoint to perform CRUD operations on MongoDB.

Implement a post route at /books/add to create a new book from the request body (name, issue date, author), save it to the books database, and return a success message.

Implement get endpoints to retrieve all books and a specific book by id using Express and Mongoose, with routes /get books and /get books/:id, async/await, and book.find or findById.

Implement a put request to update a specific book by id using a put route, find by id, and replace data with the request body in a Mongoose-based API.

Implement a delete API for books using Express and MongoDB by targeting a book id, performing find by id and delete, and returning a success or error response.

Learn how user authentication verifies valid users to access blog content, using sign up and login flows, database checks, and password hashing to protect credentials.

Learn how JWT enables secure authentication by issuing a unique token per user with a secret key, storing it in the database, and validating it with cookies or local storage.

Create a signup route in Express that registers a user, saves a user document, generates a JWT token with jsonwebtoken, stores the token on the user, and confirms success.

Protects the get books route with a JWT authentication middleware in Express.js that reads a bearer token from the authorization header, verifies it using a secret, and sets the user.

Learn how to store and manage JWT tokens on the client and server, generate tokens on signup, and persist them with local storage or redux for authorized requests.
