TypeORM - Hvordan opretter man en ny tabel og kører migrering automatisk i produktionstilstand?

For folk, der ønsker at køre migreringer med det formål at teste:IKKE i produktionsmiljø.

import {
  createConnection,
  ConnectionOptions,
  Connection,
} from 'typeorm';

import { YourEntity } from 'path/to/your/entity.ts';

const testConfig: ConnectionOptions = {
  type: 'mongodb',
  url: 'mongodb://localhost:27017',
  database: 'test',
  useUnifiedTopology: true,
  entities: [YourEntity],
  synchronize: true,
  migrations: ['migrations/*YourMigrations.ts'],
};

let connection: Connection;

connection = await createConnection({ ...testConfig });
await connection.synchronize(true);

await connection.runMigrations({
 transaction: 'all',
});

Kør med:

node -r ts-node/register ./path/to/migrations.ts

eller

node ./path/to/compiled/migrations.js
