Uncaught ReferenceError: regeneratorRuntime is not defined about babelify HOT 22 CLOSED

As documented in the caveats, generators use require the 6to5 polyfill or the regenerator runtime.

from babelify.

My apologies, and thanks for the quick response. I didn't spot that tab.

from babelify.

Generators a supported by default by chrome ( 45.0.2454.93 (64-bit)). It still doesn't work.

from babelify.

@tusharmath That's because if you compile it to ES5 it's not using the browser's native features, so it depends on the regenerator library for the ES5 code to work (the ES5 code doesn't actually use generators). Babel isn't planning to support feature detection.

from babelify.

@sebmck What's your recommended way of making the regenerator runtime available? Without also loading the core-js stuff from the polyfill?

@sebmck It's hard to keep track of discussion on Slack, and SO has too much other stuff. Have you considered Discourse (discourse.org)?

@trusktr Not much has been done with it yet, and there may be some issues with sign up, but there's https://discuss.babeljs.io/.

@jmm That looks great!! Any plans to put that on the front page?

from babelify.

@trusktr Yeah, I, or whomever, just has to do it sometime. babel/website#535

I'm also getting issues using require("babel-core/register") with co.

Trace: ReferenceError: regeneratorRuntime is not defined

I'm not running this in the browser, but I want JSX support via babel without having to transpile beforehand. Any ideas?

from babelify.

@adamkdean I fixed the regeneratorRuntime error by adding the babel-plugin-transform-runtime plugin.

from babelify.

Thanks, I decided to solve it another way but I'll keep this in mind in case I run into this again.

@xpepermint babel-plugin-transform-runtime works fine for me !

from babelify.

I also had to install babel-polyfill and include require('babel-polyfill') at the top of my source file to fix this issue.

I found this issue, and the solution for it here (google cache linked).

babel-plugin-transform-runtime not works.
have an error

Module not found: Error: Cannot resolve module 'babel-runtime/core-js/promise'

@SerkanSipahi @xpepermint

    module: {
      loaders: [
        {
          test: /\.js$/,
          exclude: /node_modules/,
          loader: "babel-loader",
          query: {
            presets: ['es2015', 'stage-3'],

          }
        }
      ]
    },

Do you have the babel-runtime module installed? npm install babel-runtime should do the trick.

from babelify.

@jonesnc thanks, but after install babel-runtime, have a new error in browser. 😂

Uncaught TypeError: (0 , _typeof3.default) is not a function

The source file is

export default () => {
  'ngInject';

  const f = () => {
    return new Promise((resolve, reject) => {
      setTimeout(() => {
        resolve(123);
      }, 2000);
    });
  };

  const testAsync = async () => {
    const t = await f();
    console.log(t);
  };

  testAsync();
};

from babelify.

I am seeing a similar error in the browser: Uncaught TypeError: (0 , _typeof3.default) is not a function

from babelify.

same here !!

from babelify.

same here :)

"Same here" without any info, makes it impossible to figure out what's going on. Please open a new issue with details like (1) what's the exact transform you're running? (2) what versions of babel & friends (3) what code you're running it on. Preferably with a repro case.
