No output on Node.js

Today I tried to use logdown v3.2.2 but when running my script I don’t see log output from logdown. Am I doing something wrong?

const logdown = require('logdown');

const logger = logdown('MyLoggerPrefix', {
  logger: console,
  prefixColor: '#FF0000'
});

logger.log('My log message with logdown.');
console.log('My log message with console.log');

The behavior was changed to mimic debuglog which is the NodeJS debugger utility. debug.js mimics it.

As a pattern, we usually set the env before a script, e.g.: https://github.com/reactjs/redux/blob/master/package.json#L26

Hi, @bennyn. This is because you haven’t set DEBUG or NODE_DEBUG env var (e.g. $ DEBUG=* node ./index.js). As I know this currently expected behavior.

You can try the following snippet to see the difference:

const logdown = require('logdown');

process.env.DEBUG='*';
logdown._setPrefixRegExps(); // this is a hack to force logdown re-parse env vars at runtime

const logger = logdown('MyLoggerPrefix', {
  logger: console,
  prefixColor: '#FF0000'
});

logger.log('My log message with logdown.');
console.log('My log message with console.log');

I think, we can discuss this behavior if it seems to be not that clear or expected
