Verified usage

Verified import paths — ran on the pinned version, not inferred.

MigrationRegistrar

✓ import { MigrationRegistrar } from 'migration-registrar'

✗ const MigrationRegistrar = require('migration-registrar')

ESM-only; CommonJS require() is not supported.

runMigrations

✓ import { runMigrations } from 'migration-registrar'

✗ import runMigrations from 'migration-registrar'

runMigrations is a named export, not default.

MigrationConfig

✓ import type { MigrationConfig } from 'migration-registrar'

✗ import { MigrationConfig } from 'migration-registrar'

MigrationConfig is a TypeScript type; use `import type` to avoid runtime bundle.

Shows how to import MigrationRegistrar and runMigrations, connect to MongoDB, execute migrations, and handle errors.

import { MigrationRegistrar, runMigrations } from 'migration-registrar'; const config = { dbUrl: process.env.DB_URL ?? 'mongodb://localhost:27017/registrar', migrationsDir: './migrations', collection: 'migrations' }; const registrar = new MigrationRegistrar(config); async function main() { try { await registrar.connect(); const results = await runMigrations(registrar); console.log('Migrations executed:', results); } catch (err) { console.error('Migration failed:', err); } finally { await registrar.close(); } } main();
