Working with js loaders

[dainyl]

Hey I'm trying to use your loader in a project that is using babel-loader on the js. However, it seems that the way javascript is required through this module doesn't respect such loaders.

I've investigated using webpackContext.exec as a replacement for require, but ran into this issue https://github.com/webpack/webpack/issues/667. That issue thread seems to imply that the functionality can be achieved using a child compiler.

Hi! I don't exactly understand the issue you found. Check the demo in the project, I used babel-loader there, and there is not such kind of issue. Could you give some example of your module usage?

So I modified the demo to highlight the issue I'm having https://github.com/dainyl/js-to-styles-var-loader/blob/changed-demo/demo/colors.js

This is the error I'm getting:

ERROR in ./~/css-loader!./~/sass-loader/lib/loader.js!..!./style.scss

For the moment the loader cannot understand es6, so temporarily you can solve the issue by using the node module system:

// fancy-red.js
module.exports = '#db0f3b';

// colors.js
var fancyRed = require('./fancy-red');

module.exports = {
    'fancy-red': fancyRed,
    'fancy-blue': '#0f9adb',
    'fancy-yellow': '#e5c63b',
    'fancy-green': '#4fdd59',
    'fancy-white': '#fcfff7',
    'fancy-black': '#1f2120',
    'fancy-pink': '#d326c8',
    'fancy-lilac': '#941ece'
};

Or rather it cannot use the es6 module api, but node api (so you can use es6 features providing by node)

[dainyl]

Yep node understands most of es6 besides the module api. I've managed to work around that by running webpack with babel via http://stackoverflow.com/a/31906902.

However, it would still be nice if this module could use the js loaders provided in the webpack.config.
