How to change nestjs log level in selfhosted

[danez]

I managed to setup affine with docker successfully but it keeps spamming DEBUG and VERBOSE messages.

Is there a way to change the log level?

After spending far too much time digging through AFFiNE logging, looks like there isn't any great option for supressing logs. The customary environment variables incl LOG_LEVEL, NESTJS_LOG_LEVEL, NODE_ENV=production, LOGGER_LEVEL, etc did not work on my end.

My rather unsatisfactory solution was to create a silence-console.js script containing:

const ANSI_RE = /\x1b\[[0-9;]*m/g;

const shouldSuppress = (chunk) => {
  const raw = typeof chunk === 'string' ? chunk : chunk.toString('utf8');
  // NestJS text format: strip ANSI codes first, then match level keyword
  const line = raw.replace(ANSI_RE, '');
  return / (LOG|DEBUG|VERBOSE) /.test(line);
};

const _stdout = process.stdout.write.bind(process.stdout);
process.stdout.write = (chunk, ...args) =>
  shouldSuppress(chunk) ? true : _stdout(chunk, ...args);

const _stderr = process.stderr.write.bind(process.stderr);
process.stderr.write = (chunk, ...args) =>
  shouldSuppress(chunk) ? true : _stderr(chunk, ...args);

and then including it in the node command. Examples:

Native/bare-metal: node -r silence-console.js ./dist/main.js

Docker: add NODE_OPTIONS: -r /scripts/silence-console.js to your environment config
