Structured objects in the loader list

[James Ide]

Currently to specify a loader you can write:

loaders: [
  { test: /\.js$/, loader: 'babel', query: {stage: 0, optional: ['runtime']} }
]

but this does not support multiple loaders. For that, only the string syntax is supported: react-hot!babel?stage=0&optional[]=runtime. I would like to be able to use the object literal syntax to specify multiple loaders with query parameters:

loaders: [
  {
    test: /\.js$/,
    loaders: [
      { loader: 'react-hot' },  // or just 'react-hot', using the string syntax as shorthand
      { loader: 'babel',  query: {stage: 0, optional: ['runtime'] }
    ]
  }
]

Looks like a good idea. Do you want to send a PR?

[James Ide]

I probably won't get around to this for awhile but it is a good PR for the community to contribute.

[Andrew Hite]

I just issued a pull request earlier today that addresses this.

Oh thanks, could you "move" this PR to the webpack repo, as webpack/core is obsolute with webpack 2. The code has been moved into:

• webpack/webpack-sources
• webpack/loader-runner
• webpack/webpack

[Tobias Koppers]

Or better wait, the loader stuff will change anyway with webpack 2, so maybe the LoadersList become obsolete too...

Just to let you know, you can use Node querystring module to accomplish this:

var queryObject = {presets: ['es2015', 'runtime'], otherQueryParam: 'foobar'};
var query = require('querystring').stringify(queryObject);
config.loaders = [{
    test: /\.js$/,
    loaders: ['ng-annotate', 'babel?' + query]
}];
