Rollup still outputting arrow functions, despite having babelrc arrow-functions transformer

[krainboltgreene]

Can't really figure out why?

node_modules/.bin/rollup --sourcemap --config rollup.config.js --input ./client/index.js --output ./tmp/client/index.js

@krainboltgreene Config should be an object. Your rollup call don't do nothing. btw it should throw as you did not add entry option.

Try this

import babel from "rollup-plugin-babel"

export default {
  format: "iife",
  plugins: [
    babel({
      exclude: "node_modules/**"
    })
  ]
};

@Rich-Harris @Victorystick I think we should throw an error if no one prop in config found.

@TrySound agreed https://github.com/rollup/rollup/pull/515

Oh, FYI I copied this rollout file from documentation.

[TrySound]

@krainboltgreene Nobody said it's cli config. It's Rollup API usage.

[krainboltgreene]

Then the documentation might be a little confusing.

[TrySound]

It's documentation of usage plugin, not cli, api, etc. For more information you should look at rollup usage here: https://github.com/rollup/rollup/wiki/JavaScript-API here https://github.com/rollup/rollup/wiki/Command-Line-Interface or here https://github.com/rollup/rollup/wiki/Build-tools

And then you just associate information of this plugin with the information from rollup wiki.
