Express.js Node.js & MongoDB

Learn how to install Express, create a simple server, and test it in the browser on port 3000, laying the groundwork for building web apps and APIs.

Configure a Node.js server on port 3000 with Express to create your first route, handle client requests, and respond with a simple message.

Learn to serve JSON data with Express by creating a sample students dataset, building a versioned API route, and returning the array of objects to the client.

Explore implementing post, put, and delete requests in a Node.js Express server, wiring routes, and logging requests, with testing via an API client.

Learn to test your Express.js API with Postman by executing get, post, put, and delete requests against the running server, observe 200 responses, and review request handling logs.

Explore the difference between get, post, put, and delete HTTP methods in Express.js, including when to respond with data, store payloads, modify records, or remove records from a database.

Learn to create a parameterized route in express to fetch a student by id using a path param, access request.params.id, and lodash's find for array lookup, with not found handling.

Explore route handlers in Express.js, learning how to define API endpoints that handle requests and responses, chain multiple handlers with next, and ensure only one sends a final response.

Learn to segment an Express app with the Express router, refactor routes into a separate file, export and import the router, and mount it with a base path.

Learn to validate route parameters in Express with a router, extract the id, ensure it is a number, and advance with next() to the next middleware.

Explore what middleware is in Express: functions that access the request, response, and next, running inside a route handler and before sending the client response.

Learn to log client requests with the Morgan middleware in an Express app, install and configure Morgan, and view formatted request logs in the console.

Explore popular middleware for express apps, including morgan, body-parser, express-session, cors, csrf, and passport, enabling APIs, request logging, sessions, cross-origin protection, and hundreds of authentication strategies.

Learn how to use the body-parser middleware with Express to parse JSON requests, access the payload via request.body, and handle a post route to receive and log data.

Persist the request body to a json array in an Express.js app by pushing the body into a students array and returning a 200 response, using the body parser.

Learn to serve static content with express by creating a public/images folder, enabling static hosting, and adding a download route to fetch images from that directory.

Learn to use template engines with Express to render dynamic content using EJS, pass data like a students array, and loop through it to display items on a view.

Learn to secure express apps with tls by generating a self-signed certificate, configure https with a key and cert, and run on port 3000 for https localhost testing.

Switch from an in-memory fake database to MongoDB via mLab, a document store, for persistent data in Express apps, with a free 500 MB option.

Spin up a free cloud MongoDB database on Amazon Web Services using the sandbox, create a deployment, and learn how to connect to your database.

Install and import mongoose, connect your Express app to a MongoDB database using a user and password, and verify the connection with a console log.

Define a mongoose schema to shape your data and convert it into a model for MongoDB operations. Use ObjectId and follow underscore naming conventions.

Create and persist a new student from the client using Express.js and Mongoose, generating a controlled ObjectId, handling errors, and returning the saved document, with Postman testing.

Learn to fetch documents from a MongoDB database and return them as JSON via a get route, using the find method with error handling, and verify with Postman.

Fetch documents by id using the student model in a routing path, employing findById, handle 404 not found and 500 errors, and validate IDs as shown.

Master updating existing MongoDB documents with PUT in Express.js by finding by id, applying body changes, saving, and validating updates.

Implement a delete route to remove a document by id from the database using the model’s find by id and remove method, handle errors, and respond with status 200.

Explore the Mongoose API to interact with models and perform queries, including limit, sort, and where clauses, guided by the official docs.

Build an Express.js API with Node.js and MongoDB, using routes, middleware, and get, post, put, and delete operations, then connect with a React-based UI.
