Problem is with pipe NODE_PATH=. node dist/index.js | ./node_modules/.bin/bunyan -o short

I have tried to use tini + modify start.sh to:

#!/bin/bash
handle_signal() {
  echo "Caught signal: $1"
  # Przesyłanie sygnału do procesu Node.js
  kill -$1 $child_pid # or directly first node
}

# Zarejestrowanie obsługi sygnałów
trap 'handle_signal SIGTERM' SIGTERM
trap 'handle_signal SIGINT' SIGINT

NODE_PATH=. node dist/index.js | ./node_modules/.bin/bunyan -o short &
child_pid=$!

wait

but without success - wait does not work and script is killed before node app - only adding sleep x helps - but it is ugly...

So I've decided to remove short formating and run application without it.

Adding a short format without a separate application is more complicated: https://stackoverflow.com/questions/20880062/how-to-set-short-output-mode-in-bunyan-by-default

Additionally, the format configuration would have to be via environment variables, because the logger is used already when extracting the configuration.

If anyone needs this format please add an issue.
