@hon2a/less-vars-loader

@hon2a/less-vars-loader is a Webpack loader providing a seamless bridge from Less variable sheets to JS files.

Use

Use the loader to extract variables from Less variable sheets (including imports, transitively) and bring them into a JS file as an object. Use inline loader syntax to set this up:

import theme from '!@hon2a/less-vars-loader!./path/to/vars.less'

Note: Use a leading ! to prevent use of other loaders.

If you're not using the file also in regular imports, you may also set up the loader in webpack.config.js and take advantage of the transform option:

module.exports = {
  module: {
    rules: [
      {
        test: /\.vars\.less$/,
        use: '@hon2a/less-vars-loader',
        options: {
          transform: ([key, value]) => [camelCase(key), /^\d+px$/.test(value) ? parseInt(value, 10) : value],
          lessOptions: { javascriptEnabled: true }
        }
      }
    ]
  }
}

Note: This loader needs to go before other loaders matching the test if there are any (e.g. when also using less-loader to load other .less files).

Development

Install

Install dependencies using:

npm install

Develop

After you modify sources, run the following (or set up your IDE to do it for you):

• format the code using npm run format
• lint it using npm run lint
• test it using npm test

and fix the errors, if there are any.

Publish

Publishing is done in two steps:

1. Create a new version tag and push it to the repository:

   npm version <patch|minor|major>
   git push --follow-tags

2. Build and publish the new version as a npm package:

   npm publish --access public
