NodeJS Express MongoDB Course With Real World Projects 2022

Install node.js from the official site across windows, mac, and linux, selecting 16.16.0 LTS or 18.7.x for latest features, then install visual studio code and add node to the path.

Create your first Node.js application by writing a simple app.js, running it in the Node environment, and using console.log to print greetings and dynamic names.

Explore core, local, and export modules in Node.js, and learn to use the file system and path modules to read and write files with exported functions.

Create a Node.js API server with Express, install Express via npm, configure routes and middleware, and run on port 5000 to support a user management app with MongoDB.

Set up the development environment by creating a project folder, initializing npm, creating package.json, installing express and mongoose, and configuring a cloud MongoDB deployment with a start script.

Connect your Node.js Express app to a MongoDB cloud database using mongoose, replacing the URL and password, establishing a connection, starting the server on port 5000, and handling errors.

Follow mvc to build a user model. Define a mongoose user schema with name, email, and password, enforce required fields and email uniqueness, and export user model for users collection.

Create a get all users API using express router and a controller that queries the user model with mongoose find. Return the users in JSON and handle errors.

Create a post route to save a user in the database by parsing JSON body, validating name, email, and password, then save with Mongoose and respond 201 or 422.

Learn to implement update operations in a node.js express app with mongodb by routing put requests, extracting ids from url parameters, validating input, and updating records with mongoose.

Create a delete endpoint in node.js express to remove a user by id from MongoDB using mongoose, returning 200 on success or 500 on error.

Add a route to fetch a user by id using mongoose in a node express app; the async controller retrieves the user by id and returns it.

Build Node.js applications from scratch, work with the file systems and modules, and create simple APIs. Develop a user management tool with create, delete, update, and get-by-id functionality.

Explore MongoDB, a NoSQL database storing documents in collections, mapping to records and SQL tables, and learn Node.js with V8 engine outside the browser plus Express framework for tasks.

Explore the relations between MongoDB collections by linking users and blogs. Each user can have multiple blogs, while each blog belongs to a single user, illustrating the database schema.

Create a backend and frontend folder, initialize npm, install nodemon and express, enable es modules, and build a blog app with users and blogs, including sign up, login, and CRUD.

Set up a MongoDB Atlas project and free cluster, connect with Mongoose, and define collections, then organize the backend into routes, controllers, and models to enable API operations.

Create a mongoose user model with name, email, password, and blocks, enforcing required fields, unique email, and password length. Build routes and a controller to fetch users, mounted at /api/user.

Create a signup POST route that reads name, email, and password from the request body, validates uniqueness, saves the user with mongoose, and returns the created user with status 201.

Hash user passwords before storing them in MongoDB using a hashing library installed via npm, then sign up stores the hash and can be tested with postman.

Create a post login route and controller to extract email and password, validate the user, compare the hashed password, and return 400 or 200 with a login message.

Create a block model with mongoose by defining a block schema including title, description, image, and user fields required, and expose routes to get blocks and create blocks under api/block.

Create a post request at /add to add a blog block to the database, wiring the block controller and saving title, description, image, and user.

Build a put route to update a blog block, sourcing the id from route params and updating the title and description in MongoDB, with error handling.

Create a get by id route that extracts the id from request.params.id, fetches the block by that id, returns a 404 if not found, and returns the block as JSON.

Create a delete blog endpoint that reads the id from the url, finds by id and removes it, and returns 200 on success with 400/500 error handling.

Relate users and blocks with mongoose objectId references and a user blocks array, and implement a transactional post flow to attach a new blog to its user.

Modify delete requests by removing a blog block from its id, populate the related user, update references, and save changes to keep blocks in sync with user data.

Create a get route to fetch a user's blogs by id, populate the user's blocks, handle errors, and return the blocks with a 200 response.

Explore the application workflow where users sign up and log in to create travel posts. Learn how MongoDB structures two collections, users and posts, with IDs linking posts to users.

Build the backend for the Modern Travel Diaries project by cloning the repository, installing dependencies, and running npm run dev to expose a basic Express API with MongoDB via mongoose.

Connects a Node.js travel diaries app to MongoDB using mongoose, secures credentials with dotenv env vars, and starts a server on port 5000 with a successful connection log.

Design and implement a user module using mvc architecture with mongoose models, controllers, and routes, defining a user schema with name, email, password, and posts, and a get users endpoint.

Create a signup post route in Node.js with Express and MongoDB, validate name, email, and password, hash the password before saving, and return 201 on success.

Implement a user login flow by adding a login route, controller, and database lookup to verify email and password, returning user id and a login successful message.

Build a complete travel post feature with a Mongoose post model, schema, and routes using Express; create, validate, and fetch posts by implementing controllers and testing with Postman.

Fetch a post by ID in a Node.js Express app by reading the ID from req.params, querying the post model, and returning the post or a 404.

Implement a put request to update a post in a node.js express MongoDB app, updating title, description, image, date, and location by id with error handling.

Learn to create a delete post endpoint in a Node.js Express MongoDB app, using the post ID from the URL to remove the post and return success or error messages.

Relate posts and users by turning fields into ObjectId references with refs, and update controllers to create, link, and delete posts inside a session and transaction.
