vuedoc vuefile vue doc parser

The Vuedoc Parser

Generate a JSON documentation for a Vue file component.

Install

This package is ESM only : Node 16+ is needed to use it and it must be imported instead of required.

npm install --save @vuedoc/parser

Extract the component name (from the name field or from the filename)
Extract the component description
Keywords support
Extract component model, props, data, computed properties, events, slots and methods
Vue 3 support with Composition API
JSX support
Class Component support
Vue Property Decorator support
Prop Types support
JSDoc support (@type, @param, @returns, @version, @since, @deprecated, @see, @kind, @author and @ignore tags)
TypeDoc tags support (@param <param name>, @return(s), @hidden, @category)

Options

| Name | Description | | --------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | filename | The filename to parse. Required unless filecontent is passed | | filecontent | The file content to parse. Required unless filename is passed | | encoding | The file encoding. Default is 'utf8' | | features | The component features to parse and extract.Default features: ['name', 'description', 'slots', 'props', 'data', 'computed', 'events', 'methods'] | | loaders | Use this option to define custom loaders for specific languages | | ignoredVisibilities | List of ignored visibilities.

Programmatic usage

Given the folowing SFC file test/examples/circle-drawer/circle-drawer-composition.vue, the parsing usage would be:

import { parseComponent } from '@vuedoc/parser';

const options = {
  filename: 'test/examples/circle-drawer/circle-drawer-composition.vue',
};

parseComponent(options)
  .then((component) => console.log(component))
  .catch((err) => console.error(err));

This will print this JSON output:

{
  "name": "CircleDrawer",
  "description": "Circle Drawer’s goal is, among other things, to test how good the common\nchallenge of implementing an undo/redo functionality for a GUI application\ncan be solved.",
  "see": "https://eugenkiss.github.io/7guis/tasks/#circle",
  "inheritAttrs": true,
  "errors": [],
  "warnings": [],
  "keywords": [
    {
      "name": "usage",
      "description": "Click on the canvas to draw a circle. Click on a circle to select it.\nRight-click on the canvas to adjust the radius of the selected circle."
    }
  ],
  "props": [ /* ... */ ],
  "data": [ /* ... */ ],
  "computed": [ /* ... */ ],
  "slots": [ /* ... */ ],
  "events": [ /* ... */ ],
  "methods": [ /* ... */ ]
}

Syntax

Add component name

By default, Vuedoc Parser uses the component's filename to generate the component name.

To set a custom name, use the name option:

<!-- CheckboxInput.vue -->
<script>
  export default {
    name: 'my-checkbox',
  };
</script>

You can also use the @name tag:

<!-- CheckboxInput.vue -->
<script>
  /**
   * @name my-checkbox
   */
  export default {
    // ...
  };
</script>

Composition usage

When using <script setup>, you need to define a comment block as a first node of your script.

<!-- CheckboxInput.vue -->
<script setup>
  /**
   * @name my-checkbox
   */

  import { ref } from 'vue';

  const checked = ref(false);
</script>

Add component description

To add a component description, just add a comment before the export default statement like:

<!-- CheckboxInput.vue -->
<script>
  /**
   * My awesome custom checkbox component
   */
  export default {
    // ...
  };
</script>

When using <script setup>, you need to define a comment block as a first node of your script.

<!-- CheckboxInput.vue -->
<script setup>
  /**
   * My awesome custom checkbox component
   * @name my-checkbox
   */

  import { ref } from 'vue';

  const checked = ref(false);
</script>

Annotate props

To document props, annotate your code like:

Legacy usage

<!-- CustomInput.vue -->
<script>
  export default {
    props: {
      /**
       * Element ID
       */
      id: {
        type: String,
        required: true,
      },
      /**
       * Element initial value
       */
      value: {
        type: String,
        default: '',
      },
    },
  };
</script>

Vuedoc Parser will automatically extract type, required and default values for properties.

Composition usage

<!-- CustomInput.vue -->
<script setup>
  const props = defineProps({
    /**
     * Element ID
     */
    id: {
      type: String,
      required: true,
    },
    /**
     * Element initial value
     */
    value: {
      type: String,
      default: '',
    },
  });
</script>

Vuedoc Parser will automatically extract type, required and default values for properties.

Composition usage with TypeScript

<!-- CustomInput.vue -->
<script lang="ts" setup>
  type Props = {
    /**
     * Element ID
     */
    id: string;
    /**
     * Element initial value
     */
    value?: string;
  };

  const props = withDefaults(defineProps<Props>(), {
    value: '',
  });
</script>

Vuedoc Parser will automatically extract type, required and default values from the type definition.

Annotate a `v-model` prop

Legacy usage

<!-- CustomInput.vue -->
<script>
  export default {
    props: [
      /**
      * The input model value
      */
      'modelValue',
    ],
    emits: ['update:modelValue'],
  };
</script>

Composition usage

To document a v-model prop using Composition API, use defineProps() macro.

<!-- CustomInput.vue -->
<script setup>
  const props = defineProps([
    /**
    * The input model value
    */
    'modelValue',
  ]);

  const emit = defineEmits(['update:modelValue']);
</script>

Vue 2 usage

To document a v-model prop legacy Vue, use the Vue's model field.

<!-- CustomInput.vue -->
<script>
  export default {
    /**
    * Use `v-model` to define a reactive value of the checkbox
    */
    model: {
      prop: 'checked',
      event: 'change',
    },
    props: {
      checked: Boolean,
    },
  };
</script>

Annotate Vue Array String Props

To document Vue array string props, just attach a Vuedoc comment to each prop:

Legacy usage

<!-- CustomInput.vue -->
<script>
  export default {
    props: [
      /**
       * ELement ID
       */
      'id',

      /**
       * The element model value
       */
      'value',
    ],
  };
</script>

Composition usage

<script setup>
  const props = defineProps([
    /**
     * ELement ID
     */
    'id',

    /**
     * The element model value
     */
    'value',
  ]);
</script>

Special tags for props

@type {typeName} Commented prop will use provided type name as type instead of type in source code. This option may be helpful in case the prop type is a complex object or a function
@default {value} Commented prop will use the provided value as default prop value. This option may be helpful in case the prop type is a complex object or function
@kind function Force parsing of a prop as a function

<!-- NumberInput.vue -->
<script>
  export default {
    props: {
      /**
       * Custom default value
       * @type Complex.Object
       * @default { anything: 'custom default value' }
       */
      custom: {
        type: Object,
        default: () => {
          // complex code
          return anythingExpression();
        },
      },
      /**
       * The input validation function
       * @kind function
       * @param {any} value - User input value to validate
       * @returns {boolean} - `true` if validation succeeds; `false` otherwise.
       */
      validator: {
        type: Function,
        default: (value) => !Number.isNaN(value),
      },
    },
  };
</script>

Prop Entry Interface

interface PropEntry {
  kind: 'prop';
  name: string;
  type: string | string[];
  default: string;
  required: boolean;
  description?: string;
  describeModel: boolean;
  keywords: Keyword[];
  category?: string;
  version?: string;
  since?: string;
  visibility: 'public' | 'protected' | 'private';
}

type Keyword = {
  name: string;
  description?: string;
};

Annotate data

To document data, annotate your code like:

Legacy usage

<!-- CheckboxInput.vue -->
<script>
  export default {
    data() {
      return {
        /**
         * Indicates that the control is checked
         */
        checked: false,
      };
    },
  };
</script>

Composition usage

<!-- CheckboxInput.vue -->
<script>
  import { ref } from 'vue';

  export default {
    setup() {
      return {
        /**
         * Indicates that the control is checked
         */
        checked: ref(false),
      };
    },
  };
</script>

Vuedoc Parser will automatically detect type for each defined data field and catch their initial value.

Special tags for data

@type {typeName} Commented data will use provided type name as type instead of type in source code. This option may be helpful in case the data type is a complex object or a function
@initialValue {value} Commented data will use the provided value as initial data value. This option may be helpful in case the data type is a complex object or function

<!-- CheckboxInput.vue -->
<script>
  export default {
    data() {
      return {
        /**
         * A data with a complex expression
         * @type boolean
         * @initialValue false
         */
        checked: ExternalHelper.getDefaultValue(),
      };
    },
  };
</script>

Data Entry Interface

interface DataEntry {
  kind: 'data';
  name: string;
  type: string;
  initialValue: string;
  description?: string;
  keywords: Keyword[];
  category?: string;
  version?: string;
  since?: string;
  visibility: 'public' | 'protected' | 'private';
}

type Keyword = {
  name: string;
  description?: string;
};

Annotate computed properties

To document computed properties, annotate your code like:

Legacy usage

<!-- CheckboxInput.vue -->
<script>
  export default {
    props: {
      checked: Boolean,
    },
    computed: {
      /**
       * Indicates that the control is selected
       */
      selected () {
        return this.checked;
      },
    },
  };
</script>

Vuedoc Parser will automatically extract computed properties dependencies.

Composition usage

<!-- CheckboxInput.vue -->
<script>
  import { computed } from 'vue';

  export default {
    props: {
      checked: Boolean,
    },
    setup(props) {
      return {
        /**
         * Indicates that the control is selected
         */
        selected: computed(() => props.checked),
      };
    },
  };
</script>

Usage with <script setup>

<!-- CheckboxInput.vue -->
<script setup>
  import { computed } from 'vue';

  const props = defineProps({
    checked: Boolean,
  });

  /**
   * Indicates that the control is selected
   */
  const selected = computed(() => props.checked);
</script>

Computed Property Entry Interface

interface ComputedEntry {
  kind: 'computed';
  name: string;
  type: string;
  dependencies: string[];
  description?: string;
  keywords: Keyword[];
  category?: string;
  version?: string;
  since?: string;
  visibility: 'public' | 'protected' | 'private';
}

type Keyword = {
  name: string;
  description?: string;
};

Annotate methods

To document methods, simply use JSDoc tags @param and @returns:

Legacy usage

<!-- CheckboxInput.vue -->
<script>
  export default {
    methods: {
      /**
       * Submit form
       *
       * @param {object} data - Data to submit
       * @returns {boolean} true on success; otherwise, false
       */
      submit(data) {
        return true;
      },
    },
  };
</script>

Composition usage

<!-- CheckboxInput.vue -->
<script setup>
  /**
   * Submit form
   *
   * @param {object} data - Data to submit
   * @returns {boolean} true on success; otherwise, false
   */
  function submit(data) {
    return true;
  }
</script>

Special tags for methods

@method <method name> You can use special tag @method for non primitive name:

<script>
  const METHODS = {
    CLOSE: 'closeModal',
  };
  
  export default {
    methods: {
      /**
        * Close modal
        * @method closeModal
        */
      [METHODS.CLOSE] () {},
    },
  };
</script>

@syntax <custom method syntax> By default, Vuedoc Parser automatically generates method syntax with typing. For example, the previous example will generate:

{
  kind: 'method',
  name: 'closeModal',
  params: [],
  returns: { type: 'void', description: undefined },
  syntax: [
    'closeModal(): void'
  ],
  category: undefined,
  version: undefined,
  description: undefined,
  keywords: [],
  visibility: 'public'
}

You can overwrite syntax generation by using tag @syntax. You can also define multiple syntax examples:

<script>
  export default {
    methods: {
      /**
       * @syntax target.addEventListener(type, listener [, options]);
      * @syntax target.addEventListener(type, listener [, useCapture]);
      * @syntax target.addEventListener(type, listener [, useCapture, wantsUntrusted  ]); // Gecko/Mozilla only
      */
      addEventListener(type, listener, options, useCapture) {},
    },
  };
</script>

Method Entry Interface

interface MethodEntry {
  kind: 'method';
  name: string;
  params: MethodParam[];
  returns: MethodReturn;
  syntax: string[];
  description?: string;
  keywords: Keyword[];
  category?: string;
  version?: string;
  since?: string;
  visibility: 'public' | 'protected' | 'private';
}

type Keyword = {
  name: string;
  description?: string;
};

type MethodParam = {
  name: string;
  type: NativeTypeEnum | string;
  description?: string;
  defaultValue?: string;
  rest: boolean;
};

type MethodReturn = {
  type: string;
  description?: string;
};

Annotate events

Legacy usage

To document events using the legacy syntax, use the emits field and tags @arg or @argument to define arguments:

Array syntax:

<script>
  export default {
    emits: [
      /**
       * Emit the `loading` event on submit
       *
       * @arg {boolean} status - The loading status
       */
      'loading',
      /**
       * Emit the `input` event on submit
       */
      'input',
    ],
  };
</script>

Object syntax with validation:

<script>
  export default {
    emits: {
      /**
       * Emit the `loading` event on submit
       *
       * @arg {boolean} status - The loading status
       */
      loading: null, // no validation

      /**
       * Emit the `input` event on submit
       */
      input: (payload) => {
        if (payload.email && payload.password) {
          return true
        } else {
          console.warn(`Invalid submit event payload!`)
          return false
        }
      },
    },
  };
</script>

Composition usage

Array syntax:

<script setup>
  const emit = defineEmits([
    /**
     * Emit the `loading` event on submit
     *
     * @arg {boolean} status - The loading status
     */
    'loading',
    /**
     * Emit the `input` event on submit
     */
    'input',
  ]);
</script>

Object syntax with validation:

<script setup>
  const emit = defineEmits({
    /**
     * Emit the `loading` event on submit
     *
     * @arg {boolean} status - The loading status
     */
    loading: null, // no validation

    /**
     * Emit the `input` event on submit
     */
    input: (payload) => {
      if (payload.email && payload.password) {
        return true
      } else {
        console.warn(`Invalid submit event payload!`)
        return false
      }
    },
  });
</script>

Composition usage with TypeScript

<script setup>
  const emit = defineEmits<{
    /**
     * Emit the `loading` event on submit
     *
     * @arg {boolean} status - The loading status
     */
    (e: 'loading', value: boolean): void

    /**
     * Emit the `input` event on submit
     */
    (e: 'input', value: boolean): void
  }>()
</script>

Vue 2 usage

Vuedoc Parser automatically extracts events from component template, hooks and methods when using Vue 2:

<script>
  export default {
    created() {
      /**
       * Emit the `loading` event on submit
       * @arg {boolean} status - The loading status
       */
      this.$emit('loading', true);
    },
    methods: {
      submit() {
        /**
        * Emit the `input` event on submit
        */
        this.$emit('input', true);
      },
    },
  };
</script>

<template>
  <div>
    <!-- Emit the `click` event on submit -->
    <button @click="$emit('click', $event)">Submit</button>
  </div>
</template>

You can use special keyword @event for non primitive name:

<script>
  const EVENTS = {
    CLOSE: 'close',
  };

  export default {
    methods: {
      closeModal() {
        /**
          * Emit the `close` event on click
          * @event close
          */
        this.$emit(EVENTS.CLOSE, true);
      },
    },
  };
</script>

Event Entry Interface

interface EventEntry {
  kind: 'event';
  name: string;
  description?: string;
  arguments: EventArgument[];
  keywords: Keyword[];
  category?: string;
  version?: string;
  since?: string;
  visibility: 'public' | 'protected' | 'private';
}

type Keyword = {
  name: string;
  description?: string;
};

type EventArgument = {
  name: string;
  type: NativeTypeEnum | string;
  description?: string;
  rest: boolean;
};

Annotate slots

Vuedoc Parser automatically extracts slots from template. You must use @prop tag to define properties of a slot:

<template>
  <div>
    <!-- Default slot -->
    <slot></slot>
    <!-- Use this slot to set the checkbox label -->
    <slot name="label">Unnamed checkbox</slot>
    <!--
      Slot with keywords and
      multiline description

      @prop {User} user - The current user
      @prop {UserProfile} profile - The current user's profile
    -->
    <slot name="header" v-bind:user="user" v-bind:profile="profile"/>
  </div>
</template>

Annotate slots defined in Render Functions

To annotate slots defined in Render Functions, just attach the tag @slot to the component definition:

<script>
  /**
   * A functional component with slots defined in render function
   * @slot title - A title slot
   * @slot default - A default slot
   */
  export default {
    functional: true,
    render(h, { slots }) {
      return h('div', [
        h('h1', slots().title),
        h('p', slots().default),
      ]);
    },
  };
</script>

You can also use the tag @slot to define dynamic slots on template:

<template>
  <div>
    <template v-for="name in ['title', 'default']">
      <!--
        @slot title - A title slot
        @slot default - A default slot
      -->
      <slot :name="name"></slot>
    </template>
  </div>
</template>

Slot Entry Interface

interface SlotEntry {
  kind: 'slot';
  name: string;
  description?: string;
  props: SlotProp[];
  keywords: Keyword[];
  category?: string;
  version?: string;
  since?: string;
  visibility: 'public' | 'protected' | 'private';
}

type Keyword = {
  name: string;
  description?: string;
};

type SlotProp = {
  name: string;
  type: string;
  description?: string;
};

Ignore items from parsing

Use the JSDoc's tag @ignore to keeps the subsequent code from being documented.

<!-- CheckboxInput.vue -->
<script>
  export default {
    data: () => ({
      /**
       * This will be ignored on parsing
       * @ignore
       */
      checked: false,
    }),
  };
</script>

You can also use the TypeDoc's tag @hidden.

Tags Extraction

You can attach keywords (or tags) to any comment and then extract them using the parser.

Usage

<script>
  /**

Working with Mixins

Starting v4.0.0, Vuedoc Parser implements a mechanism to automatically load needed import declarations to parse and extract metadata.

With this new capability, Vuedoc Parser is now able to handle Vue mixins automatically.

Parsing control with `options.features`

options.features lets you select which Vue Features you want to parse and extract.

The default value is defined by VuedocParser.SUPPORTED_FEATURES array.

Usage

Only parse name, props, computed properties, slots and events:

import { parseComponent } from '@vuedoc/parser';

const options = {
  filename: 'test/examples/circle-drawer/circle-drawer-composition.vue',
  features: [ 'name', 'props', 'computed', 'slots', 'events' ],
};

parseComponent(options)
  .then((component) => Object.keys(component))
  .then((keys) => console.log(keys));
  // => [ 'name', 'props', 'computed', 'slots', 'events' ]

Parse all features except data:

import { parseComponent, VuedocParser } from '@vuedoc/parser';

const options = {
  filename: 'test/examples/circle-drawer/circle-drawer-composition.vue',
  features: VuedocParser.SUPPORTED_FEATURES.filter((feature) => feature !== 'data'),
};

parseComponent(options)
  .then((component) => Object.keys(component))
  .then((keys) => console.log(keys));
  // => [ 'name', 'description', 'keywords', 'model',
  //      'props', 'computed', 'events', 'methods', 'slots' ]

Using Plugins

Vuedoc can be extended using plugins.

Adding a Plugin

To use a plugin, it needs to be added to the devDependencies of the project and included in the plugins array options.plugins. For example, to provide support of Vue Router, the official @vuedoc/plugin-vue-router can be used:

$ npm add -D @vuedoc/plugin-vue-router

// main.js
import { parseComponent } from '@vuedoc/parser';
import { VueRouterPlugin } from '@vuedoc/plugin-vue-router';

const component = await parseComponent({
  plugins: [
    VueRouterPlugin,
  ],
  // ...
});

Official Plugins

| Name | Description | Documentation | | ----------------- | -------------------------------- | -------------------------------------------------------------------------- | | Vue Router Plugin | The Vue Router plugin for Vuedoc | @vuedoc/plugin-vue-router | | Vuex Plugin | The Vuex plugin for Vuedoc | @vuedoc/plugin-vuex |

Building Plugins

Plugins Overview

A Vuedoc plugin is an object with one or more of the properties, parsing hooks described below, and which follows our conventions. A plugin should be distributed as a package which exports a function that can be called with plugin specific options and returns such an object.

Plugins allow you to customise Vuedoc's behaviour by, for example, handling and parse parsing result object before sending the final result, or adding support of a third-party modules in your node_modules folder.

Conventions

Plugins should have a clear name with vuedoc-plugin- prefix.
Include vuedoc-plugin keyword in package.json.
Plugins should be tested.
Document your plugin in English.

Interface

type Plugin = (parser: Parser) => PluginDefinition;

interface PluginDefinition {
  /**
   * Custom import resolver
   */
  resolver?: ImportResolver;

  /**
   * List of resource files to preload before parsing
   */
  preload?: string[];

  /**
   * Additional composition tokens for advanced components
   */
  composition?: Partial<ParsingComposition>;

  /**
   * Handle parsing result
   */
  handleParsingResult?(component: ParseResult): void;
}

interface Parser extends EventTarget {
  /**
   * Resolved options
   */
  readonly options: ResolvedOptions;

  addEventListener(
    type: EventType,
    callback: EventListener<EntryEvent<EventType>>,
    options?: boolean | AddEventListenerOptions
  ): void;

  addEventListener<T extends MessageEventType>(
    type: EventType,
    callback: EventListener<MessageEvent<EventType>>,
    options?: boolean | AddEventListenerOptions
  ): void;

  addEventListener(
    type: 'end',
    callback: EventListener<EndEvent>,
    options?: boolean | AddEventListenerOptions
  ): void;
  ): void;

  addEventListener(
    type: 'fatal',
    callback: EventListener<FatalErrorEvent>,
    options?: boolean | AddEventListenerOptions
  ): void;
}

type EventType = 'computed' | 'data' | 'description' | 'event' | 'inheritAttrs' | 'keyword' | 'method' | 'model' | 'name' | 'prop';

Please see PluginInterface from types/index.d.ts from detailled types.

Language Processing

Loader API

Please see TypeScript definition file for the Loader class.

Built-in loaders

| Language | Load by default? | Module | | ---------- | ---------------- | --------------------------------------------------------------------------------------------------------- | | HTML | Yes | @vuedoc/parser/loaders/html | | JavaScript | Yes | @vuedoc/parser/loaders/javascript | | Pug | No | @vuedoc/parser/loaders/pug | | TypeScript | Yes | @vuedoc/parser/loaders/typescript | | Vue | Yes | @vuedoc/parser/loaders/vue |

Create a custom loader

The example below uses the abstract Vuedoc.Loader class to create a specialized class to handle a template with the CoffeeScript language. It uses the built-in PugLoader to load Pug template:

import { parseComponent, Loader } from '@vuedoc/parser';
import { PugLoader } from '@vuedoc/parser/loaders/pug';
import { compile } from 'coffeescript';

class CoffeeScriptLoader extends Loader {
  load (source) {
    const outputText = compile(source);

    this.emitScript(outputText);
  }
}

const options = {
  filecontent: `
    <template lang="pug">
      div.page
        h1 Vuedoc Parser with Pug
        // Use this slot to define a subtitle
        slot(name='subtitle')
    </template>

    <script lang="coffee">
      ###
      # Description of MyInput component
      ###
      export default
        name: 'MyInput'
    </script>
  `,
  loaders: [
    /**
     * Register CoffeeScriptLoader
     * Note that the name of the loader is either the extension
     * of the file or the value of the attribute `lang`
     */
    Loader.extend('coffee', CoffeeScriptLoader),

    // Register the built-in Pug loader
    Loader.extend('pug', PugLoader),
  ],
};

parseComponent(options).then((component) => {
  console.log(component);
});

Output

{
  name: 'MyInput',
  description: 'Description of MyInput component',
  slots: [
    {
      kind: 'slot',
      visibility: 'public',
      description: 'Use this slot to define a subtitle',
      keywords: [],
      name: 'subtitle',
      props: []
    }
  ],
  // ...
}
