How to use Ogma logger with Nest Commander in main.ts?

[tukusejssirs]

In CommandFactory.run(), I can add CommandFactoryRunOptions object, however, logger property accepts only Logger from @nestjs/logger.

Any logger that satisfies Nest's logger property is valid, however using ogma directly for that isn't always nice to have to instantiate the Ogma instance yourself, so instead with v3.7.0 you can do something like

async function bootstrap() {
  const app = await CommandFactory.createWithoutRunning(AppModule);
  app.useLogger(app.get(OgmaService)); // assuming `OgmaModule.forRoot()` has been imported
  await CommandFactory.runApplication(app);
}
bootstrap();

Docs on the createWithoutRunning

Okay, I tried this out. My app works when I add this to main.ts and when I define OgmaModule.forRoot() and OgmaModule.forFeatures() in the module file.

However, when I add constructor(@OgmaLogger(SomeCommand.name) private readonly logger: OgmaService) {} into the command file, TS errors out with TS2377: Constructors for derived classes must contain a 'super' call., so I add super() into the constructor (i.e. constructor(...) {super()}), but then the app does not work: it can be built and run, but the exit code is always 1. I have no idea how to get debug this (even when I use NODE_DEBUG='*', no error is thrown). 🤔

Got a reproduction? For sake of getting debug logs you can always do logger: new ConsoleLogger() to get Nest's default output

Here’s the reproduction.

Steps:

1. Clone.
2. Install NPM dependencies.
3. Build (pnpm build).
4. pnpm should:fail fails with exit code 1 (no log from the app itself). This is not expected.
5. pnpm should:succeed fails with exit code 1 (no log from the app itself). This is not expected.
6. In src/cli/command/plc.command.ts, comment out lines 18 and 32.
7. Re-build the app.
8. pnpm should:fail outputs 'not_an_ip_address' is not a valid IP address. and exits with 2. This is expected.
9. pnpm should:succeed outputs { inputs: [], options: { ip: '1.1.1.1' } } and exits with 0. This is expected.

Now, I have no idea why the output and exit codes of steps 4 and 5 and not the same as of steps 8 and 9 respectively (of course, the log on L32 should be the only difference).

Move PlcCommand to the providers array

Oh, such a such newbie mistake! 🤦‍♂️ Thanks! 🙏
