NodeJs API for Beginners (Marketplace with AWS & MongoDB)

Set up a fresh node project, install express, create a server, define a get route for the home path, respond with a message, and run with nodemon for auto-restart.

Separate routes from your Node.js API by organizing post handlers in a dedicated routes file, exporting and importing them, and using object destructuring for clarity and scalability.

Discover how middleware controls request flow using the use method, log details with Morgan, and create custom middleware that calls next to proceed. Apply authentication and validation to protect routes.

Create a controllers folder and move post request handling from routes to a dedicated post controller, wiring it with Express to act as middleware.

Build an API in Node.js that returns JSON objects for get and post requests, uses Postman for testing, and demonstrates composing posts arrays with titles.

Learn to scaffold a node API with MongoDB using mlab, create and retrieve posts, and connect via Mongoose with dotenv-managed credentials, handling deployments and basic error handling.

Install mongoose and connect to mongodb with mongoose.connect, log success, and handle errors by logging the connection error message; resolve authentication issues by creating a database user.

Define a post schema with required title and body, min and max lengths, and validation messages, then export a Mongoose model for use in the post controller.

build a create post endpoint in nodejs, reading json from the request body, saving the post with mongoose, and returning the created post.

Learn to validate post creation using Express Validator, implement user-friendly error messages, and apply a validator middleware to enforce title and body constraints before saving to the database.

Learn to fetch all posts from the database using the Post model, return a clean json response, and customize fields with select to show id, title, and body.

Refactor the route controllers to reduce repetition and prepare the app for authentication. Restrict post creation to authenticated users and plan for login, registration, password reset, and social login.

Build a robust node.js api for a two-type buyer-seller real estate marketplace using MongoDB and jwt authentication, with aws for images and emails, and endpoints for ads, login, and search.

Create and configure a Node.js api project using express, Morgan, cors, and nodemon, with a modular entry point at index.js and a /api route returning the current time.

Connect to MongoDB using a local or Atlas connection string, configure with environment variables, install mongoose and dotenv, and verify a successful database connection before routing requests.

Organize routes by creating a server folder and an auth router for login, handling post /login and returning JSON from the request body. Prefix with /api and test with postman.

Organize a Node.js API by moving route callbacks into an auth controller (auth.js), exporting api and login handlers, and importing them in routes to run after a successful mongoose connection.

Explore a login system that hashes and compares passwords using bcrypt. Then switch to Node.js's crypto pbkdf2 with salt and iterations, and use JWT-based authentication.

Learn a unified login and register workflow in a Node.js API using bcrypt, on-the-fly user creation, email validation via welcome emails, and token-based authentication with AWS SES and S3.

Set up a root AWS account, then create an IAM user and dev group with S3 and SES full access, and generate an access key and secret for development.

Learn how to verify email addresses in AWS SES within a sandbox environment, manage production access, and test email delivery for a Node.js marketplace app.

Set up AWS environment variables for a node.js API, including access key, secret, region, and API version, and configure verified from emails and app-related env vars for sending emails.

Build a Node.js helper to send welcome emails via AWS SES, configuring an SES client, environment-driven params, and an HTML message in a send email function for routing.

Send a welcome email from the login endpoint by importing a mail helper, destructuring the request email, and handling success or error responses, with SES debugging and AWS region notes.

Build a mongoose user model for a real estate app, detailing username, email, password, name, address, and role with validation, then enable on the fly login and registration.

Implement login validation in a Node.js API, validating email using an email validator library and enforcing password rules, and return clear json error responses.

Register new users by checking email existence, sending a welcome email, hashing passwords, and generating a six-character nano id username; issue a seven-day JWT and return user data without password.

The login flow validates input, creates or finds a user by email, compares the plain password with the stored hash, and issues a signed token while omitting the password.

Add a forgot password route that generates a temporary password, hashes it, and saves it. Send the password via email, then log in and change it on the profile.

Learn to implement a password reset flow by composing email params from environment variables, sending an HTML message with a temporary password, and integrating it into the forgot password function.

Create a require sign in middleware that validates the jwt from the authorization header, decodes it with the secret, and attaches the user to the request for protected routes.

Create a get route for the currently logged in user with require sign in middleware, fetch the user by id from request.user, omit the password, and return the user data.

Add a put route to update password for authenticated users, validate and trim input, enforce minimum length, hash the new password, and save or update the user record.

Updating the username requires sign-in and uniqueness. Validate input, check for an existing username, and return an error if taken; update by id and omit the password from the response.

Learn to implement image uploads for a real estate marketplace using AWS S3, including bucket setup, policy creation, and resizing with Multer before uploading, then prepare ad creation routes.

Learn how to implement an authenticated image upload route in Node.js, including setting up Multer storage, handling single and multiple uploads, validating files, resizing images, and preparing for S3 upload.

Resize multiple images with sharp, upload to AWS S3 using a modular flow that records mime type and uploaded by the current user, then return image URLs in JSON.

Create a post route to upload multiple images to AWS S3 using token auth and form-data. Learn region configuration, avoid ACL conflicts, and resize images with Serp.

Implement a secure remove image endpoint in a node.js api, validating the uploader with the uploaded by field, and delete the image from aws s3 using a delete object command.
