Ionic-app-scripts: Error in ionic cordova build android --prod

[AnkitMaheshwariIn]

FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

Error when running command: ionic cordova build android --prod

Note: that ionic build android, ionic run android and ionic serve all works fine.

I've read many topics that says once the project gets bigger, it stops working.

_It was working the day before issue arrive. It stopped working as we added more files and JSON for translation of app in multi-language._

Is it a known issue? Is there any solution?

It's been more than a month, does anyone have an answer to at least those 2 questions?

• Is it a known issue?
• Is there any solution?

Happens for me too

A guy posted this in another issue and it works for now, but it should probably be documented as a limitation.

1. add this to the package.json scripts
   "ionic:build": "node --max-old-space-size=8192 ./node_modules/@ionic/app-scripts/bin/ionic-app-scripts.js build",

2. run the command:
   npm run ionic:build --prod

3. run the commands:

cordova build android --release
cordova build ios --release

There seems to be a memory leak in webpack when using the module concatination plugin and source maps. I got rid of the memory issues by setting ionic_source_map_type to cheap-source-map

in package.json worked for me:

  "config": {
    "ionic_source_map_type": "cheap-source-map"
  }

Please keep in mind that this will skip source maps for dev builds as well. We can make a custom webpack config file as workaround.

I still need a solution for this. I'm able to run it locally following the steps provided, but on my CI I can´t change from ionic cordova build ... --prod to npm run ionic:build

[nandyx]

Update the dev dependency @ionic/app-scriptsto 3.1.9 and build correctly.

refer to this link if you are using firebase https://forum.ionicframework.com/t/memory-leak-when-generate-a-production-version-of-small-app/129077/5?u=michaele

@nandyx it is not building even if i give him 8 Gb of ram it consume it and no build is released.... why we we separate everywhere

ionic cordova build --release

and

ionic cordova build --release --prod --aot

I think this is the command we are looking for my build was becoming 1.4 from 9 before something crashes and i cannot rebuild...

I try to install 8.9.0 8.9.4 10.0.0 node and reinstall all ionic and cordova packages nothing works....

You can try:
For iOS:

"node --max-old-space-size=8192 /usr/local/bin/ionic cordova build ios --prod"

Similar for Android:

"node --max-old-space-size=8192 /usr/local/bin/ionic cordova build android --prod"

[Stradivario]

@raghav-khunger this solution is not working everywhere.And the bundler isn't suppose to use 8 + GB of ram :)

[raghav-axero]

@Stradivario Well, for me adding that 8GB indicator worked and I was able to build it.
