wazzup test task: backend

Simple Notes application with user registration and notes sharing.

Requirements

• Node.js >=14 (LTS)
• PostgreSQL
• Redis

Installation and Running

Create Postgres db. Create .env file in project's root. See .env.sample for details.

1. npm run initdb - Initialize DB migrations and seeds.
2. npm start - starting backend in dev mode.

Pros and Cons

• no framework in use (like Nest), only 'low-level' express
• no passportjs auth, low-level token manipulation (use of JWT)
• no high-level ORM and no low-level API's to DB calling raw queries. Instead, used query builder
• so created kind of 'models' in services for dealing with DB
• MVC-simplified pattern
• no email confirmation, user delete, password change for simplicity (and not mandatory as of task description)
• typescript
• express middleware and route handlers use promises instead callbacks
• No SSL
• Redis connection is unprotected
• Postgres connection is unprotected
• JWT claims are not used for simplicity; redis is for blacklisted tokens
• Redis is not used for saving shared link info
