React Next.js Rest API Backend Typescript Course 2025

Open a project folder, install a specific Next.js version (15.2.1) with npx create dash next app, and verify the setup by running npm run dev inside the project folder.

Install Prisma at version 6.4.1 to avoid incompatibilities with different Next.js versions. Run npm i prisma@6.4.1 @prisma/client@6.4.1 and verify the Prisma client and Prisma versions.

Learn to create route groups in Next.js by organizing api folders into auth and app, which don't appear in the URL, and access endpoints like get all.

Learn how to create a get request endpoint in Next.js, handle it asynchronously, and return a JSON response with NextResponse.json.

Explore creating a post request alongside get requests, wiring a saving data endpoint in route.ts, and testing with Thunder Client to observe a 405 method not allowed error.

Register a free MongoDB account, create a project and a cluster, choose a free deployment near Cape Town, and connect MongoDB to Prisma using VS Code.

Define a Prisma user type enum with values seeker and employer, assign default seeker for new users, and align the type field with the API and UI constraints.

Create a category enum for a prism post in a React Next.js TypeScript backend, with a general default and languages like JavaScript, PHP, React, Next.js, React Native, and Python.

Push Prisma models to MongoDB and sync schemas with Prisma db push, updating Shopify and Post models and refreshing the job B5 project to reflect the new schema.

Discover how to implement a prisma client singleton in a Next.js app by creating a lib singleton prisma module that exports one prisma instance to power a sign-up endpoint.

Learn how to receive signup data from the frontend in a Next.js app, extract JSON from the incoming request, await the data, and return it as a JSON response.

Validate signup data against the schema to ensure correct structure and data types. Check for an existing user with Prisma find unique on email, and store only if unique.

Learn to generate a JSON web token for signup, sign it with a secret key, set expiration, and return it to secure the API.

Create a sign in route in a Next.js api under auth, validate email and password with Zod, infer client data types, and handle bad requests and user checks with Prisma.

Sign in flow continues by validating the user with bcrypt, generating a jwt token from minimal user data, and returning an unauthorized message for invalid credentials.

Use a singleton Prisma to create a post, return the created item when success is true, and verify it in MongoDB while sending API errors for failure.

Create a get all posts route using a route.ts file, exporting a sync handler with try/catch, returning API data via prisma find many and testing the get request.

Learn to extract pagination query parameters from the URL using Next.js style search params, convert them to integers, apply defaults for page and limit, and pass them to data fetching.

Develop pagination logic in REST API using page and limit, compute total pages from total posts, and return metadata with next and previous URLs built from the request base URL.

Create a delete account route in Next.js using a dynamic slug to receive the user id, and use Prisma to perform a multi-transaction to delete posts and the user.

Learn to implement a delete post by ID API route in a Next.js TypeScript app using Prisma, with dynamic routing, existence checks, and proper error handling.

Create a dynamic Next.js post route to update user data by id, validate the request body, fetch the user with Prisma, and update fields, hashing the password when it changes.

Validate and refine the user update password logic by testing the endpoint, confirming passwords are hashed, and ensuring name updates apply when a password is provided.

Create a post update api route with a dynamic post id, validate input against the post schema, and enable optional updates to title, description, salary, location, closing date, and category.

Learn to align frontend types with the backend schema using Zod validation, fix type mismatches, and implement and test the update post endpoint in a TypeScript React Next.js API project.

Learn how middleware in Next.js acts as an interceptor between requests and responses, validating JWT tokens before protected endpoints and allowing public routes like sign in and sign up.

Learn how middleware receives the authorization token from the client via the request header in Next.js server functions and uses a bearer token to secure API endpoints.

Learn to extract and validate tokens in middleware: detect bearer tokens, split and obtain the jwt, support raw tokens, and apply authorization checks to protect api routes.

Verify a JWT token in an async middleware using a secret key to validate the payload. Inject user data into the request for endpoint access control and guard against tampering.
