Does not honor .babelrc

babel-watch does not seem to honor my .babelrc

Currently:

{
  "presets": ["latest", "react", "stage-0"],
  "plugins": ["transform-decorators-legacy"]
}

Running my code with babel-watch and this error is thrown: regeneratorRuntime is not defined While babel-node I am good to go

@larron Thanks to your example code I managed to get that issue reproed.

It appears that babel-node automatically imports babel-polyfill for every process it runs. In my opinion this may lead to confusion as whenever you run your code with babel-node it will work fine, but when you want to run it in production it is recommended to build it first and then run with regular node. In which case you’ll end up getting the same error as you have here.

Now I believe that the proper solution is what @jadsonlourenco suggested and I no longer consider it to be a workaround. I’ve also found an alternative solution which makes babel add babel-polyfill in the transpilation step and you don’t need to add it manually:

npm install --save-dev babel-plugin-transform-runtime babel-runtime

Then add this to your .babelrc plugin section:

{
  "plugins": [
    ["transform-runtime", {
      "polyfill": false,
      "regenerator": true
    }]
  ]
}

I’m closing this issue, and will update troubleshooting section on the main page with information about this issue.

Thanks everyone for participating in the discussion

Try: npm i babel-polyfill --save-dev, then add import 'babel-polyfill' to your main.js file.
