[banjankri]

Tested against webpack 4.28.x
Fixes #814

[banjankri]

Following a common approach, taken by ramda for instance: https://github.com/ramda/ramda/. They compile multiple flavors of their library to distribute. Please let me know if different path is envisioned.

@banjankri - thanks for taking on this old issue. Quite a huge PR, let me review it over the weekend 👍

[profnandaa]

You can un-stage this change, version change is done by @chriso during publishing, since many other changes will be in by then.

[profnandaa]

Since we are having to repeat all the code in the /es folder, it means changes have to be made in duplicate. Could we think of a build process where this code is generated into the folder and all the necessary transformations made? 🤔

[banjankri]

This is done already, please see "build:es" script in package.json. It is then invoked as part of the "build" script. Added also cleanup for it accordingly, following what was done for "clean:browser" and "clean:node".

[profnandaa]

Oh, got it 👍

[profnandaa]

@chriso -- could you check out this PR...

[banjankri]

hey @chriso @profnandaa , just pinging to get the PR reviewed please :)

[profnandaa]

Because it was introducing a huge diff, I thought @chriso will be best to take on this...

[banjankri]

@chriso would you maybe have some time to go through this PR please?

[chriso]

@banjankri sorry for the delay in reviewing this. I agree with the general approach and would be happy to merge – we just need it to be rebased to pull in the latest changes.

[banjankri]

Merged with upstream master. Can see there is a non-empty diff on validator.js, which I would not expect, @profnandaa @chriso could you check if that is due to merge please?

[chriso]

Looks good @banjankri. Thanks for your contribution! 😄

This is available in 12.1.0

Sorry for a stupid question. Do I understand correctly that I can do import { isBlah } from "validator" and expect all other methods to be excluded from the app bundle? Library typings don't seem to support that.
