App
  |– client
  |– public

{
  "postcss": {
    "plugins": {
      "postcss-plugin": {}
    }
  }

    "postcss-plugin": {}
  }
}

postcss.config.js

Create a postcss.config.js file.

App
  |– client
  |– public
  |
  |- postcss.config.js
  |- package.json

module.exports = (ctx) => {
  plugins: {
    'postcss-plugin': options
  }
}

module.exports = (ctx) => {
  plugins: [
    require('postcss-plugin')(ctx.plugin)
  ]
}

Options

Plugin options can take the following values.

null: Plugin loads with defaults.

'postcss-plugin': null

[Object]: Plugin loads with given options.

'postcss-plugin': { option: '', option: '' }

false: Plugin will not be loaded.

'postcss-plugin': false

Order

Plugin order is determined by declaration in the plugins section.

{
  plugins: {
    'postcss-plugin': false, // plugins[0]
    'postcss-plugin': false, // plugins[1]
    'postcss-plugin': {}     // plugins[2]
  }
}

Context

When using a function (postcss.config.js), it is possible to pass context to postcss-load-plugins, which will be evaluated before loading your plugins. By default ctx.env (process.env.NODE_ENV) and ctx.cwd (process.cwd()) are available.

Examples

postcss.config.js

module.exports = (ctx) => {
  plugins: {
    postcss-import: null,
    postcss-bem: ctx.bem || null,
    cssnano: ctx.env === 'development' ? false : null
  }
}

API

const { readFileSync } = require('fs')

const postcss = require('postcss')
const pluginsrc = require('postcss-load-plugins')

const css = readFileSync('index.css', 'utf8')

const ctx = { bem: { style: 'bem' } }

pluginsrc(ctx).then((plugins) => {
  postcss(plugins)
    .process(css)
    .then(({ css }) => console.log(css))
}))
