Logging

runSeeders is silent by default (logging: false). Pass logging to opt into output:

[UserSeeder] Starting...
[UserSeeder] Done in 42ms
[UserSeeder] Failed after 3ms   ← logged at warn level

logging: true — console logger

Routes output through ConsoleLogger, which wraps the global console. Progress messages use console.log; failures use console.warn.

await runSeeders([UserSeeder], { em, logging: true })

Supply a custom logger via the logger option — any object implementing SeederLogger works:

await runSeeders([UserSeeder], {
  em,
  logging: true,
  logger: {
    log: (msg) => myLogger.info(msg),
    warn: (msg) => myLogger.warn(msg),
    info: () => {},
    error: () => {},
    debug: () => {},
  },
})
