Token based authentication with Fastify, JWT and Prisma

This is a repository for a JWT authentication service using Fastify, Prisma, sqlite db and TypeScript. It allows users to register, login, logout, and get a list of users from a sqlite database. It uses bcrypt for hashing passwords, zod for validating schemas, and fastify-jwt for generating and verifying tokens.

Usage

The project exposes four endpoints for user authentication:

• GET /: returns a list of users with their name, id, and email. Requires an access token in the cookie or the authorization header.
• POST /register: creates a new user with the given name, email, and password. Returns the user data and an access token.
• POST /login: logs in an existing user with the given email and password. Returns the user data and an access token.
• DELETE /logout: logs out the current user by clearing the access token cookie.

You can use a tool like Postman Here are some examples:

• GET /: returns a list of users with their name, id, and email. Requires an access token in the cookie or the authorization header.
• POST /register: creates a new user with the given name, email, and password. Returns the user data and an access token.
• POST /login: logs in an existing user with the given email and password. Returns the user data and an access token.
• DELETE /logout: logs out the current user by clearing the access token cookie.
