You will also need this, to auto-import Buffer from your buffer alias wherever it finds it:

new webpack.ProvidePlugin({
  Buffer: ['buffer', 'Buffer'],
})

See: duplotech/create-react-app@d0be703

I'm building a library which creates a umd, cjs builds. I use some packages which require Buffer polyfill.
What configuration should i use so that Buffer module gets polyfilled in my outputs.?

I tried resolve alias field and it didn't work for Buffer. ( it worked for others like crypto, process etc)

[DanielRuf]

https://github.com/feross/buffer is for example a solution for the browser but it depends on the library that you use. This is not a really a problem with webpack itself imo.

[DanielRuf]

Buffer in general is not part of the browser APIs and only a NodeJS API.

Regarding the browser field, see https://webpack.js.org/configuration/resolve/#resolvealiasfields and webpack/webpack#151

If this does not work try importing directly https://unpkg.com/browse/[email protected]/dist/es/browser.js

Thanks @sebinsua
That seems to have resolved that issue. However, when i try to use libraryTarget: "module",
i get the following error:
Module external type is not implemented yet

Is the feature not yet built?
