Preserve Licenses

[jzacharuk]

Is there an option to preserve licenses of node_modules while using npm run build?

It's my understanding that even permissive licenses such as MIT require a copy of the license/copyright notice. By using the react-scripts build and deploying the output to a server it seems that requirement is being missed.

Are people meeting these requirements another way?

I would greatly appreciate some clarity on this.

We're just using Uglify which preserves JSDoc-style comments that contain @preserve or @license in them. You can submit PRs to the libraries you're using to keep those in the compiled bundle if you'd like. I'm not sure if legally your distributed bundle counts as redistribution of the source code, or as compiled code, and I can't give you legal advice on this.

How do we tell create-react-app to preserve @preserve or @license? When I use react-scripts build, even though I have a @license in my index.js file, it still doesn’t include that license in the minified version.

Sounds like a bug then, @heymartinadams -- can you please file a new issue for this?

Done. Thanks, @Timer!
