generate

What it does

Reads all migration files, applies them to an in-memory database, produces:

Output	Purpose
`./damian/.generated/tables.ts`	TypeScript table definitions for queries
`./damian/.generated/typings.ts`	Wraps custom typings from `./damian/typings.ts`
`./damian/db.sql`	SQL dump of current schema (for version control)

Run

npx damian generate

pnpm damian generate

yarn damian generate

Skip migrations from dump

Use devDumpIgnore in damian.config.ts to exclude specific files from db.sql while including them in type generation. Useful for cleaning up schema dumps by omitting seed data:

damian.config.ts

import { config } from 'damian'

export default config({
    driver: 'postgres',
    url: process.env.DATABASE_URL,
    devDumpIgnore: ['20240101000000_seed_dev_data.sql']
})
