uncaughtException: Cannot find module '...\\server_fastify\\lib\\worker.js'

[Brandon Largeau]

Hello,

I wanted to use pino-pretty on my Fastify SSR server on my Angular project, but it seems that it's not finding a module.
I think it's related to how Angular compiles the project.

I'm getting this error:

The dist folder looks as follow for a compiled Angular project (dev mode):

I'm following the doc from https://www.fastify.io/docs/latest/Reference/Logging/#enable-logging

const fastify = Fastify({
    logger: {
      transport: {
        target: 'pino-pretty',
        options: {
          translateTime: 'HH:MM:ss Z',
          ignore: 'pid,hostname',
        }
      }
    },
    connectionTimeout: options.connectionTimeout
  });

Is there an alternative to format the logs (removing fields, adding new ones)?

NodeJS 18.13.0
Fastify 4.12.0
pino-pretty 9.1.1
Typescript 4.8.4
Angular 14.2.x (not using esbuild)

Thanks for the answer.

I checked the plugin and how I could integrate that in our Angular project. I think it would add too much "overhead" and maintenance steps.

I will try to configure formatting using formatters, base, etc (without pino-pretty)
