MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 bundled listeners added to [Bundler]. Use emitter.setMaxListeners() to increase limit

🐛 bug report

MaxListenersExceededWarning warning when running app built with Parcel.

MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 bundled listeners added to [Bundler]. Use emitter.setMaxListeners() to increase limit

🎛 Configuration (.babelrc, package.json, cli command)

package.json

{
  "scripts": {
    "react-start": "export NODE_OPTIONS=--trace-warnings; parcel -p 3000 index.html --out-dir build",
    "start": "concurrently \"cross-env BROWSER=none yarn react-start\" \"wait-on http://localhost:3000 && electron . \"",
    ...
}

🤔 Expected Behavior

No such warnings should be raised.

😯 Current Behavior

After running yarn start, which includes running the React app with --trace-warnings, the Electron+React app starts up without any problems. However, we see the MaxListenersExceededWarning in the terminal:

(node:62770) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 bundled listeners added to [Bundler]. Use emitter.setMaxListeners() to increase limit

💁 Possible Solution

Might be a problem with the file watcher chokidar for hot reloading?

Same here with vue app, seems to be new, didn't get the error before this week.

I have the same issue . It can be reproduced at https://github.com/moctrash/parcel2-react-refresh

@mischnic is this related to #2277 ?

[aminya]

I get this as well. Happens when I run parcel build (always). It does not happen with parcel serve.

console: (node:16716) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 17 error listeners added to [Writ
eStream]. Use emitter.setMaxListeners() to increase limit
(Use `node --trace-warnings ...` to show where the warning was created)
console: (node:16716) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 17 close listeners added to [Writ
eStream]. Use emitter.setMaxListeners() to increase limit

[mischnic]

At least in @vazra's case, this seems to be triggered by wait-on, which pings the dev server before bundling has finished:

parcel/packages/reporters/dev-server/src/Server.js

Line 355 in 473e579

this.once('bundled', response);

If someone else also gets this warning, please set the environment variable NODE_OPTIONS to show a stack trace for the warning, e.g.

NODE_OPTIONS=--trace-warnings yarn start
cross-env NODE_OPTIONS=--trace-warnings npm run start

Does the console output look like this? (containing @parcel/reporter-dev-server/lib/Server.js and connect)

Strange, that line is only called once on startup.

parcel/packages/reporters/cli/src/render.js

Line 33 in 473e579

let spinner = ora({

[mischnic]

@aminya Will the last warning be fixed when upgrading ora?

[aminya]

@mischnic I don't think so, but it will have some performance benefits.

Using bl (#163) changes the error. This may mean that this error is not related to ora.
