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",

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>
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>
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.
v-model propLegacy 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>
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>
@type {typeName}@default {value}@kind 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>
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;
};
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}@initialValue {value}<!-- 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;
};
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;
};
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;
};
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;
};
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;
};
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.
You can attach keywords (or tags) to any comment and then extract them using the parser.
Usage
<script>
/**
* Component description
*
* @license MIT
*/
export default { /* ... */ };
</script>
Note that the description must always appear before keywords definition.
Parsing result:
{
"name": "my-checkbox",
"description": "Component description",
"keywords": [
{
"name": "license",
"description": "MIT"
}
]

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.
options.featuresoptions.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' ]
Vuedoc can be extended using plugins.
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,
],
// ...
});
| 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 |
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

Please see TypeScript definition file for the Loader class.
| Language | Load by default? | Module |
|---|---|---|
| HTML | Yes | @vuedoc/parser/loaders/html |
| JavaScript | Yes | @vuedoc/parser/loaders/javascript |

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',

slots: [
{
kind: 'slot',
visibility: 'public',
