Creating Plugins

Plugins give you the ability to modify Docz processes, default configurations and create hooks for build and render. This is a perfect place to integrate Docz with other tools.

To create a plugin you just need to use the createPlugin method from docz-core

import { createPlugin } from 'docz-core'

const myPlugin = () => createPlugin({
  setConfig: (config) => /* ... */,
  onCreateBabelConfig: (args) => /* ... */,
  onCreateDevServer: (args) => /* ... */,
  onCreateWebpackConfig: (args) => /* ... */,
  modifyFiles: (files, args) => /* ... */,
  onPreBuild: () => /* ... */,
  onPostBuild: () => /* ... */,
})
