Hi, did you follow our React integration guide? Could you please provide steps to reproduce your issue?

[Manimall]

faced the same problem

[ma2ciek]

@Manimall, could you share more details?

+1 here

import Editor from '@ckeditor/ckeditor5-react';
import BalloonEditor from '@ckeditor/ckeditor5-build-balloon';

const EditorComponent = () => (
    <Editor
      editor={BalloonEditor} // without this line build works just fine
      ...
    />
);

upgrading to latest react-scripts and adding --max_old_space_size=2048 fiixed my problem

[Denny966]

Got the same issue, more details:

• create a new react app
• install "@ckeditor/ckeditor5-build-classic": "^16.0.0" and "@ckeditor/ckeditor5-react": "^2.1.0"
• try to build it
• error

[ma2ciek]

Thanks @Denny966 for details.

Could you also tell what's your OS and package manager (and their versions)?

@Manimall, could you share more details?

install editor and create new app with react-create app laugn app

then trying to build it - but it gives an error - the error is like @NeerajThapliyal shown above

i tried both with the classic editor and inline editor - doesn't matter - I've got errors while trynna build a project(

[ma2ciek]

Could you also tell what's your OS, package manager and Node.js versions?

[ma2ciek]

Looking at the stack trace I guess that the problem occurs because babel has a lot of files to index, parse, transpile and generate source maps for them. Currently I'd just advice to add --max_old_space_size=4096 until we find a better solution.

Hi @ma2ciek , I tried to use --max_old_space_size=8192, but it shows me the same error, JavaScript heap out of memory.

Sadly, this does not seem to work with my app as well, even with enlarging the size. OS: Win10 Npm v6.13.4 Node v12.14.1

[nchristopherteague]

Windows: 10 npm: 6.13.2 node: 12.14.1 react scripts: 3.4.1

The steps I took is explained in https://github.com/ckeditor/ckeditor5/issues/7522

I get the javascript heap message when I copy the package from the online builder, run npm install "local folder" and then try to reference it in my component.

I have tried the --max_old_space_size=4096 but still doesn't work.

1: Am I doing this correctly or do I need to use the package differently? 2: Any other suggestions on what I can do to get it to work?

Got same Issue

FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory when try to build project with ckeditor5 build from online builder in reactjs

[mgandley]

Also getting this error. Possibly related to https://github.com/facebook/create-react-app/issues/8096. Disabling source maps per that issue worked, but not an ideal solution.

Not sure why this is happening with a custom build from the online builder but not from the standard builds.

[mgandley]

See https://github.com/ckeditor/ckeditor5/issues/6770. Pretty sure the custom builds are using the pre-monorepo-builds and are behind a few versions. Building from source using the instructions in https://github.com/ckeditor/ckeditor5/issues/7645 allowed me to make a build that did not cause any memory errors in my react application.

[jayjaydluffy]

I can't also get rid of the error. I tried doing a custom build following the instructions here but to no avail. --max_old_space_size=8192 also has no chance.

OS: Ubuntu 18.04 Node: v12.13.0 npm: 6.12.0 react-scripts: 3.3.0

@mgandley can you please share to us your build? did you base the steps laid out here?

[jayjaydluffy]

Today I was able to overcome the Heap Size Error by a combination of things:

1. Created a custom build (a balloon block type) using the online builder and then using the instructions [here].(https://github.com/ckeditor/ckeditor5/blob/72a64b941da2933d2e90ec3b1fab04d06500d3c7/docs/builds/guides/integration/advanced-setup.md), but I still got the error. I settled though with the latter version.
2. I updated react and react-scripts to latest (16.13.1 and 3.4.1, respectively). My node version is at 12.13.0.
3. Deleted node_modules and yarn.lock then ran yarn install to reinstall all dependencies.

I was surprised I've no longer got the error.

[pulkit1joshi]

Same issue. Any fixes?

1. Used online builder
2. npm add file:./ckeditor5
3. Works on dev but npm run build gives heap error

Removing the ckeditor gives no error

[vinayak25]

If you are react-app-rewired, simply increase the memory to --max-old-space-size=2048 build, it should work

[pulkit1joshi]

This didn't solve my issue. Are the steps that I used correct?

[vinayak25]

can you provide some extra details like node, react version and os details

[vinayak25]

Any update on this?

[muftisamiullah]

having same issue --max-old-space-size=8192 build, this doesnt also work, kindly provide some advise

[haseebuchiha]

Hi is there any update related to this issue? I am still facing this issue on my app. I even went as far as setting the -max-old-space-size to 16gigs. It works with utilizing 13 gigs on ram on my activity monitor. However my deployment machine does not have enough ram to run this.

For additional information "react-scripts": "4.0.1", "react": "^17.0.1", node: "15.10.0"

[imsateesh]

@haseebuchiha @vinayak25 I found the solutions using the below help -

That problem is related to large files in your project. I'm using create-react-app, and I got that error, after doing some search, it seems one solution is this.

Put in .env file: GENERATE_SOURCEMAP=false

@imsateesh THANKS ALOT. My app is finally working. However it is a bit concerning to just disable something. Is there any source where I might be able to read up on this.

[nvmnghia]

This is not related to ckeditor5-react, it's related to the custom build editor, but I think I should add it here if someone trips on like me: somehow maybe you're missing babel runtime, or the latest version of it. So do yarn add -D @babel/runtime, or npm install --save-dev @babel/runtime.
