How to remove source maps?

[lavrton]

Are there any ways to disable/remove them?
It will be nice if I can just set source_map_enabled: false in static.json.

What's your motivation to make this change? Curious if this is a build time issue, a bandwidth concern, or something else.

Your specific suggestion would not apply here, because static.json is config for the web server, not javascript/create-react-app concerns.

Found a pertinent discussion about making such a customization through create-react-app.
As mentioned there, you may eject & modify webpack config to avoid generating source maps at all.

Otherwise, the inner & main buildpack could be forked and modified to delete that file after build. See architecture for how these pieces fit together.

@mars I just don't want to show full source code in production mode.

In other projects where I use create-react-app I manually remove *.map files as build step. This is suggested solution (facebook/create-react-app#2742 (comment)).

I think create-react-app-buildpack can do this too. Just need to delete *.map files.

That's not a convincing reason for why I should add such a feature. You're welcome to eject or fork the buildpack to do this.

I just found that create-react-app-buildpack use npm run build. So to remove sources maps I can simply update build script to:

"build": "react-scripts build && rm build/static/js/*.map",

Thanks for following-up @lavrton. Glad to see the fix ended up being so simple.

Is there a way to just skip/avoid some files to the sourcemap?

@hugomosh
There is a simple one I found in other place.
We can now disable sourcemap with putting below setting in a .env file (at the root of the project):
GENERATE_SOURCEMAP=false

SET GENERATE_SOURCEMAP=false
npm run build
