NestJS with Drizzle ORM

This is an example/starter using the following stack:

• NestJS
  • Fastity
  • Custom logger (pino with pino-pretty)
    • Custom logger with possibility to add request id to the logs
  • Loading and processing environment variables with Configuration
  • Tests with Vitest
• Drizzle ORM
  • Multiple schemas
  • Custom logger (with interpolated queries)
  • Example with reusable DAO
    • abstract.dao shows a way to abstract some reusable Drizzle ORM queries, e.g.,
      • getAll - get all entries for a specific entity
      • getById - get entries with specific id
      • getBySingleKey - get all entries with a specific value for the given key
• PostgresSQL

It's an attempt (simple and concise) to show how to create multiple schemas using Drizzle ORM. Currently, Drizzle doesn't provide an easy way to do so.

Why do we want multiple schemas?

Sometimes for testing purposes we want to have the following schemas

• test1 - Schema for test1
• test2 - Schema for test2
• ...
• testN - Schema for testN

This way, we can run each test against a specific schema, so that, the tests are contained.

This might also be useful for a multi-tenant approach.
