Config

Name Type Default Description
path {String} loader.resourcePath PostHTML Config Path
ctx {Object} {} PostHTML Config Context

If you want to use are shareable config file instead of inline options in your webpack.config.js create a posthtml.config.js file and place it somewhere down the file tree in your project. The nearest config relative to dirname(file) currently processed by the loader applies. This enables Config Cascading. Despite some edge cases the config file will be loaded automatically and no additional setup is required. If you don't intend to use Config Cascading, it's recommended to place posthtml.config.js in the root ./ of your project

src
├── components
│   ├──  component.html
│   ├──  posthtml.config.js (components)
├── index.html
├── posthtml.config.js (index)
└── webpack.config.js

Path

If you normally place all your config files in a separate folder e.g ./config it is necessary to explicitly set the config path in webpack.config.js

webpack.config.js

{
  loader: 'posthtml-loader',
  options: {
    config: {
      path: 'path/to/.config/'
    }
  }
}

Context

Name Type Default Description
env {String} 'development' process.env.NODE_ENV
file {Object} { dirname, basename, extname } File
options {Object} {} Plugin Options (Context)

posthtml.config.js

module.exports = ({ file, options, env }) => ({
  parser: 'posthtml-sugarml',
  plugins: {
    'posthtml-include': options.include,
    'posthtml-content': options.content,
    'htmlnano': env === 'production' ? {} : false
  }
})

webpack.config.js

{
  loader: 'posthtml-loader',
  options: {
    config: {
      ctx: {
        include: {...options},
        content: {...options}
      }
    }
  }
}

  options: {
    parser: 'posthtml-sugarml'
  }
}

{Function}

webpack.config.js

{
  loader: 'posthtml-loader',
  options: {
    parser: require('posthtml-sugarml')()
  }
}

{Boolean}

webpack.config.js

{
  loader: 'posthtml-loader',
  options: {
    skipParse: false
  }
}

Render

{String}

webpack.config.js

{
  loader: 'posthtml-loader',
  options: {

  }
}

{Function}

webpack.config.js

{
  loader: 'posthtml-loader',
  options: {
    parser: require('posthtml-you-render')()
  }
}

webpack.config.js

{

  options: {
    plugins (loader) {
      return [
        require('posthtml-plugin')()
      ]
    }
  }
}
