Package Exports

@vue/component-compiler-utils/package.json

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@vue/component-compiler-utils) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Lower level utilities for compiling Vue single file components

This package contains lower level utilities that you can use if you are writing a plugin / transform for a bundler or module system that compiles Vue single file components into JavaScript. It is used in vue-loader version 15 and above.

The API surface is intentionally minimal - the goal is to reuse as much as possible while being as flexible as possible.

API

parse(ParseOptions): SFCDescriptor

Parse raw single file component source into a descriptor with source maps.

interface ParseOptions {
  source: string
  filename?: string
  sourceRoot?: string
  needMap?: boolean
}

interface SFCDescriptor {
  template?: SFCBlock
  script?: SFCBlock
  styles: SFCBlock[]
  customBlocks: SFCCustomBlock[]
}

interface SFCCustomBlock {
  type: string
  content: string
  attrs: { [key: string]: string }
  start: number
  end: number
  map: RawSourceMap
}

interface SFCBlock extends SFCCustomBlock {
  lang?: string
  src?: string
  scoped?: boolean
  module?: string | boolean
}

compileTemplate(TemplateCompileOptions): TemplateCompileResults

Takes raw template source and compile it into JavaScript code. The actual compiler (vue-template-compiler) must be passed so that the specific version used can be determined by the end user.

It can also optionally perform pre-processing for any templating engine supported by consolidate.

interface TemplateCompileOptions {
  source: string
  filename: string

  // See https://github.com/vuejs/vue/tree/dev/packages/vue-template-compiler
  compiler: VueTemplateCompiler
  compilerOptions?: VueTemplateCompilerOptions

  // Template preprocessor
  preprocessLang?: string
  preprocessOptions?: any

  // Transform asset urls found in the template into `require()` calls
  // This is off by default. If set to true, the default value is
  // {
  //   video: ['src', 'poster'],
  //   source: 'src',
  //   img: 'src',
  //   image: 'xlink:href'
  // }
  transformAssetUrls?: AssetURLOptions | boolean

  // For vue-template-es2015-compiler, which is a fork of Buble
  transpileOptions?: any

  isProduction?: boolean  // default: false
  isFunctional?: boolean  // default: false
  optimizeSSR?: boolean   // default: false
}

interface TemplateCompileResult {
  code: string
  source: string
  tips: string[]
  errors: string[]
}

interface AssetURLOptions {
  [name: string]: string | string[]
}

Handling the Output

The resulting JavaScript code will look like this:

var render = function (h) { /* ... */}
var staticRenderFns = [function (h) { /* ... */}, function (h) { /* ... */}]

It does NOT assume any module system. It is your responsibility to handle the exports, if needed.

compileStyle(StyleCompileOptions)

Take input raw CSS and applies scoped CSS transform. It does NOT handle pre-processors. If the component doesn't use scoped CSS then this step can be skipped.

interface StyleCompileOptions {
  source: string
  filename: string
  id: string
  map?: any
  scoped?: boolean
  trim?: boolean
}

interface StyleCompileResults {
  code: string
  map: any | void
  rawResult: LazyResult | void // raw lazy result from PostCSS
  errors: string[]
}
