Plugin API

version

Type: string

The version string for the @vue/cli-service version that is loading the plugin.

assertVersion(range)

• Arguments

  • {integer | string} range - a semver range that @vue/cli-service needs to satisfy

• Usage

  While api.version can be useful in general, it's sometimes nice to just declare your version. This API exposes a simple way to do that.

  Nothing happens if the provided version is satified. Otherwise, an error will be thrown.

getCwd

• Usage: Returns a current working directory

resolve

• Arguments

  • {string} path - relative path from project root

• Returns

  • {string}- the resolved absolute path

• Usage: Resolve a path for the current project

hasPlugin

• Arguments

  • {string} id - plugin id, can omit the (@vue/|vue-|@scope/vue)-cli-plugin- prefix

• Returns

  • {boolean}

• Usage: Check if the project has a plugin with given id

registerCommand

• Arguments

  • {string} name
  • {object} [opts]

  {
    description: string,

    options: { [string]: string }
  }
  

  • {function} fn

  (args: { [string]: string }, rawArgs: string[]) => ?Promise
  

• Usage: Register a command that will become available as vue-cli-service [name].

chainWebpack

• Arguments

  • {function} fn

configureWebpack

• Arguments

  • {object | function} fn

• Usage: Register a webpack configuration object that will be merged into the config OR a function that will receive the raw webpack config. The function can either mutate the config directly or return an object that will be merged into the webpack config.

configureDevServer

• Arguments

  • {object | function} fn

• Usage: Register a dev serve config function. It will receive the express app instance of the dev server.

resolveWebpackConfig

• Arguments

  • {ChainableWebpackConfig} [chainableConfig]

• Returns

  • {object} - raw webpack config

• Usage: Resolve the final raw webpack config, that will be passed to webpack.

resolveChainableWebpackConfig

• Returns

  • {ChainableWebpackConfig}

• Usage: Resolve an intermediate chainable webpack config instance, which can be further tweaked before generating the final raw webpack config. You can call this multiple times to generate different branches of the base webpack config.
