Source code for Kaizen's backend. Kaizen is a web-native collaborative task management software for humans™. Provides a web API that the client uses to function and perform various tasks. Developed as a NitHub final project submission.

• Supports creating tasks with priorities, and due dates.
• Supports teams for collaborative task management.
• User management system and access controls.
• Secure authentication and authorization via JWT access tokens.

• Sensitive endpoints require authorization via access tokens.
• Passwords are hashed before storing in the database.
• User verification is required before accessing protected endpoints, users are verified via email.
• Adheres to industry best practices with abstraction and encapsulation via OOP.
• Rate limiting to minimize / prevent API abuse.
• Deployment via Docker images.

• NodeJS (Typescript & ExpressJS): asynchronous server-side js runtime engine.
• PostgreSQL: for primary persistent application data.
• Prisma: ORM for working with PostgreSQL.
• Redis: for fast key-value caching.
• MailerSend: for sending emails securely.
• Docker: for containerization & deployments.

An overview of API endpoints that are available. The core API features are accessible through the /v1 prefix.

   1. [POST] /auth/signup - Validates credentials and attempts to create a new Kaizen user.

   2. [POST] /auth/signin - Validates credentials and attempts to login authorized users. Will generate a verification link if the user is not verified.

   3. [POST] /auth/generate - This endpoint generates verification links for successfully created users. The link is only valid for 24 hours.

3. Email:

   1. [GET] /email/verify - This endpoint attempts to verify users based on a previously generated code.

   4. [DELETE] /task/personal/:username?id=ID - Deletes a singular task with the provided id for the authorized user, rejects request otherwise.

After cloning the repository, you can setup a local instance by following these steps:

1. install npm packages using yarn install.
2. Configure environment variables using the .env.example template, see the configuration options here.
3. Perform database migrations using ./scripts/db.sh --migrate, after generating a Prisma client via npx prisma generate.
4. Start the development server using ./scripts/dev.sh.

These scripts need execution permission which you can grant using chmod +x <path-to-script>
