Uncaught ReferenceError: setImmediate is not defined

[sneko]

Hi,

I get errors as soon as I try to write logs with winston inside my Vue.js project. Here is the code:

// Create a logger to adjust logs
const logger = winston.createLogger({
  level: "debug",
  transports: [
    new winston.transports.Console(),
  ]
});

console.log(1111);
logger.debug("dqsqsdqsd");
console.log(2222);

And the "2222" is never showed, it fails before with the following error:

logger.js?e7af:237 Uncaught ReferenceError: setImmediate is not defined
    at Console.log (console.js?bc48:43)
    at Console._write (index.js?d13f:81)
    at doWrite (_stream_writable.js?dc14:428)
    at writeOrBuffer (_stream_writable.js?dc14:417)
    at Console.Writable.write (_stream_writable.js?dc14:334)
    at DerivedLogger.ondata (_stream_readable.js?ad71:619)
    at DerivedLogger.EventEmitter.emit (events.js?faa1:81)
    at addChunk (_stream_readable.js?ad71:291)
    at readableAddChunk (_stream_readable.js?ad71:278)
    at DerivedLogger.Readable.push (_stream_readable.js?ad71:245)

I don't understand what's the problem. There is not that much information about that kind of error :/

I'm using Winston 3.1.0 inside a TypeScript project.

Do you have any idea that could help please?

Thank you,

May it could help?

That's funny, I read a post (browserify/timers-browserify#25 (comment)) that advises to inject these variables globally to make it working, so in my Vue settings I custom webpack with:

    config
      .plugin('provide')
      .use(webpack.ProvidePlugin, [{
        setImmediate: ['setimmediate', 'setImmedate'],
        clearImmediate: ['setimmediate', 'clearImmedate']
      }]);

Now I'm able to reach "setImmediate" in my Chrome console, but Winston is still showing me the error... when looking at sourceMap the error is here:

  log(info, callback) {
    setImmediate(() => this.emit('logged', info));

Any idea @indexzero ?

EDIT: I also removed my lock file and the node_modules directory but it doesn't change anything 😢

EDIT2: Maybe winston plugin could use setImmediate from a package that suppports browser compatibility? (https://github.com/YuzuJS/setImmediate)

I'm using a workaround thanks to @jpsear (#1354 (comment)). I'm leaving this issue opened until having a feedback from one of the maintainer 🔨

Yeah, that workaround is a good way to go I think. Perhaps we can bake that workaround into winston itself, or make a "browser faq" like I suggested in #1354. Let's keep #1354 open for further discussion, would be good to do something there. Thanks!
