IE11 and other old browsers (how to make it work) about observable-hooks

[crimx]

Both esm and es2015 support tree-shaking, excpet the esm is transpiled to es5. The es2015 runs better in modern browsers and should have samller minification result.

Glad it works. Happily closing this.

Sorry for the inconvenience. I will look into this and see what I can do.

No problem, we found the issue eventually. Code-wise I don't think anything needs to be changed, just a heads up to people having similar issues.

[crimx]

Would you checkout the observable-hooks@alpha and see if it solve your issue? Should works without transpilation.

[SweVictor]

It does, very nice and quick fix! IE11 happy again without any special webpack configuration!

A quick double-check by hacking observable-hooks@alpha to always point to the es2015 version makes IE11 crash again validating the fix on your side actually has effect and that webpack by default chooses the "module" entry in package.json.

All this makes one wonder if tree-shaking and minification results in webpack could be improved by transpiling ALL node_modules... That's an investigation for another day though!

Thanks again

(hacked package.json that makes IE11 error out again, actual observablehooks@alpha works well

  "main": "dist/cjs/index.js",
  "module": "dist/esm2015/index.js",
  "es2015": "dist/esm2015/index.js",
