seam-pgm v1.3.2

seam-pgm (Seam node-pg-migrate)

Seam uses node-pg-migrate to run database migrations.

node-pg-migrate requires some custom commands/setup to be compatible with the typical seam configuration. Namely...

• Use Typescript
• Put migrations in src/db/migrations
• "Standard Shorthands" for uuids and created_at timestamps
• Code to automatically run migrations in tests
• Automatic zapatos/kysely type generation
• Reset database and migrate scripts
• Automatic src/db/zapatos which dumps the database structure
• Automatic src/db/structure which dumps the database structure

This module encapsulates all that functionality into one, easy-to-use module.

Usage

Scripts

Note: seam-node-pg-migrate is abbreviated to seam-pgm, either is valid as an executable

• seam-pgm init - Set up a project to use seam-pgm
• seam-pgm create-migration - create new migration
• seam-pgm reset - drop database and recreate, then migrate
• seam-pgm migrate - migrate database
• seam-pgm generate - migrate database and generate new types and structure

  // Directory to store migrations, structure and database utility files
  dbDir: "./src/db", // optional
}
