RESTful API Masterclass with Express and Node.js

Explore Node.js, an open-source cross-platform environment built on the V8 engine for server-side, non-blocking applications. Learn how npm, Express, and asynchronous programming enable scalable API-based services.

Master event driven architecture by emitting events, registering listeners, and handling event callbacks to synchronize multiple events in node-based programs. This approach offers flexibility and programming simplicity through inter-object communication.

Explore what restful APIs are and how they enable stateless, client–server communication with scalable, decoupled services using URIs, caching, and standard web protocols.

Explore how Express, a flexible Node.js framework, simplifies API development with routing, middleware, and modular requests, and how to install it via npm and integrate template engines.

Set up a first web server using Express in a Node.js environment, create routes with get methods, define request and response handlers, and run the server on port 3000.

Learn how nodemon automatically restarts a node server when code changes, install node, run node index, and verify the server update with a browser refresh.

Explore environment variables for configuring an Express app at runtime, using process.env to set port dynamically and provide defaults, with macOS export and Windows set commands.

define route parameters in express using colon syntax, and access them via request.params to retrieve specific data from the URL, tested by entering a parameterized URL in the browser.

Learn to handle http get requests to fetch all students or a specific student, and post data to the server using JavaScript with Express and Node.js.

Handle http post requests by creating new student objects, manage IDs manually, and validate inputs with middleware before posting and testing APIs using Postman.

Master input validation with the joy library in a Node.js and Express REST API, define a validation schema, enforce required fields and minimum rules, and inspect errors in Postman.

Learn to handle http put requests to update a student by id, validate with a schema, return a 400 on invalid input, and update the student while sending the response.

Master handling http delete requests by deleting a specific id, locating its index, and removing it from the data store. Practice with postman by building crud endpoints for employees.
