I just publish actionscable-esm.
Look at https://github.com/yuki-torii/actioncable-esm

Feel free to open a PR.

BTW, does actioncable@5.1.0-beta1 work?

@rafaelfranca it was working on actionvable@5.0.1, it does not work on actioncable@5.1.0-beta1

Weird. The way it was released was the same and the code seems to be the same. I'm not a webpack user, could you investigate why those version doesn't work?

Thanks reply 😃 .

@rafaelfranca In fact, it's not same :D

@smarquez1 @rafaelfranca actionvable@5.0.1 actioncable@5.1.0-beta1 not work, just get undefinded.

I think you should improve js module build way. Because more and more people use webpack2 to build app.

About javascript module

• UMD: UMD builds can be used directly in the browser via a <script> tag.

• CommonJS: CommonJS builds are intended for use with older bundlers like browserify or webpack 1.

• ES Module: ES module builds are intended for use with modern bundlers like webpack 2 or rollup.

Yeah. What I could get is that sprockets-export doesn't Es modules yet. https://github.com/javan/sprockets-export/blob/master/lib/sprockets/export/template.js.erb

@javan is that correct?

Found the issue. Fix in progress here #28385

FWIW, I tested actioncable@5.0.1 and actioncable@5.0.2, and both work fine with webpack using require or import statements. actioncable@5.1.0-beta1 does not.

@javan Thx. You are a great help.
