Generate documentation markdown files from VueJs components using the vue-docgen-api.
Install the module directly from npm:
yarn add -D vue-docgen-cli
In a terminal window, navigate to the root of your project, then type the following command.
yarn vue-docgen src/components/**/*.vue docs/components
If your components are in the src/components
folder, this will generate one .md
file per component.
vue-docgen
can take two nameless arguments. The components
glob to locate components and the destination
directory.
Should vue-docgen watch for modifications of your components and update generated markdown files accordingly?
Specify the path of your configuration file. By default, docgen
will look for docgen.config.js
in the current folder.
yarn vue-docgen -c config/docgen.config.js
Should vue-docgen output more information?
same as --logLevel debug
Specify the log level. Can be error
, warn
, info
, debug
, trace
.
yarn vue-docgen --logLevel debug
default is error
Create a docgen.config.js
at the root of your project to avoid having to specify command-line arguments everytime.
All of the command-line arguments, except for the --config
, can be replaced by lines in the docgen.config.js
file.
In a config file you can even be more specific. Each of the following configurations is optional.
const path = require('path') module.exports = { componentsRoot: 'src/components', // the folder where CLI will start searching for components. components: '**/[A-Z]*.vue', // the glob to define what files should be documented as components (relative to componentRoot) ignore: '*.test.ts', // optional glob to ignore files outDir: 'docs', // folder to save components docs in (relative to the current working directry) apiOptions: { ...require('./webpack.config').resolve, // inform vue-docgen-api of your webpack aliases jsx: true // tell vue-docgen-api that your components are using JSX to avoid conflicts with TypeScript <type> syntax }, getDocFileName: (componentPath: string) => componentPath.replace(/\.vue$/, '.md'), // specify the name of the input md file getDestFile: (file: string, config: DocgenCLIConfig) => path.join(config.outDir, file).replace(/\.vue$/, '.doc.md'), // specify the name of the output md file templates: { // global component template wrapping all others see #templates component: require('templates/component'), events: require('templates/events'), methods: require('templates/methods'), props: require('templates/props'), slots: require('templates/slots'), // static template to display as a tag if component is functional functionalTag: '**functional**' }, docsRepo: 'profile/repo', docsBranch: 'master', docsFolder: '', editLinkLabel: 'Edit on github' }
type:
string | string[]
, default:"src/components/**/[a-zA-Z]*.{vue,js,jsx,ts,tsx}"
Glob string used to get all the components to parse and document.
type:
string
, default:"docs"
The root directory for the generation of the markdown files
type:
string
, optional
If you specify this, all documentation will be generated in one single page. The path of this file is relative to the outDir.
The following configuration will generate one single file: myDocs/components.md
module.exports = { outDir: 'myDocs', outFile: 'components.md' }
type:
string
, default:path.dirname(configFilePath)
The folder where CLI will start searching for components. Since the folder structure will be kept from source to destination, it avoids having uselessly deep scaffoldings.
src
ââââcomponents
ââââButton.vue
ââââCounterButton.vue
ââââFunctional.vue
ââââInput.vue
If you simply use src/components/**/[A-Z]*.vue
as source glob and docs
as outDir, you will get this.
src
ââââcomponents
ââââButton.vue
ââââCounterButton.vue
ââââFunctional.vue
ââââInput.vue
docs
ââââsrc
ââââcomponents
ââââButton.vue
ââââCounterButton.vue
ââââFunctional.vue
ââââInput.vue
Specifying componentsRoot: 'src/components'
and using **/[A-Z].vue
will skip the two useless levels of hierarchy.
type:
DocGenOptions
, optional
Allows you to give vue-docgen-api some config. Most notably, you can specify wether your components contain JSX code and the alias configured in your webpack.
type:
(componentPath: string) => string
, default:(componentPath) => path.resolve(path.dirname(componentPath), 'Readme.md')
By default it will find the Readme.md
sibling to the component files. Use this to point docgen to the files that contain documentation specific to a component.
type:
(file: string, config: DocgenCLIConfig) => string
, default:(file, config) => path.resolve(config.outDir, file).replace(/\.\w+\$/, '.md')
Function returning the absolute path of the documentation markdown files. If outFile is used, this config will be ignored.
type:
boolean
, default:false
Should vue-docgen keep on watching your files for changes once the first files are generated?
type:
Templates
, optional
An object specifying the functions to be used to render the components.
For example:
file: component.ts
export default function component( renderedUsage: RenderedUsage, // props, events, methods and slots documentation rendered doc: ComponentDoc, // the object returned by vue-docgen-api config: DocgenCLIConfig, // the local config, useful to know the context fileName: string, // the name of the current file in the doc (to explain how to import it) requiresMd: ContentAndDependencies[], // a list of all the documentation files // attached to the component documented. It includes documentation of subcomponents { isSubComponent, hasSubComponents }: SubTemplateOptions // are we documenting ): // a sub-component or does the current component have subcomponents string { const { displayName, description, docsBlocks } = doc return ` # ${displayName} ${description ? '> ' + description : ''} ${renderedUsage.props} ${renderedUsage.methods} ${renderedUsage.events} ${renderedUsage.slots} ${docsBlocks ? '---\n' + docsBlocks.join('\n---\n') : ''} ` }
And the partial for slots
import { SlotDescriptor } from 'vue-docgen-api' import { cleanReturn } from './utils' export default ( slots: { [slotName: string]: SlotDescriptor }, opt?: { isSubComponent: boolean hasSubComponents: boolean } ): string => { const slotNames = Object.keys(slots) if (!slotNames.length) { return '' // if no slots avoid creating the section } return ` ## Slots | Name | Description | Bindings | | ------------- | ------------ | -------- | ${slotNames .map(slotName => { const { description, bindings } = slots[slotName] const readableBindings = // serialize bindings to display them ina readable manner bindings && Object.keys(bindings).length ? JSON.stringify(bindings, null, 2) : '' return cleanReturn( `| ${slotName} | ${description} | ${readableBindings} |` ) // remplace returns by <br> to allow them in a table cell }) .join('\n')} ` }
type:
Array<DocgenCLIConfig>
, optional
Allows to group components into pages. Each page will inherit its parent properties.
const path = require('path') module.exports = { componentsRoot: 'src/components', // the folder where CLI will start searching for components. outDir: 'docs', pages: [ { components: 'atoms/**/[A-Z]*.vue', // the glob to define what files should be documented as components (relative to componentRoot) outFile: 'atoms.md' // saved as `docs/atoms.md` }, { components: 'molecules/**/[A-Z]*.vue', // the glob to define what files should be documented as components (relative to componentRoot) outFile: 'molecules.md' // saved as `docs/molecules.md` } ] }
type:
boolean
, default:false
Generate an example for components that have neither <docs>
block nor a markdown file to provide examples of usage.
type:
string
, optional
Force the Current Working Directory. Useful in monorepos.
type:
(relativePath: string) => string
, default:p => `https://github.com/${config.docsRepo}/edit/${branch}/${dir}/${p}`
Gets the link to the documentation edition from
type:
string
, optional
If you specify the docsRepo, and you do not want to specify getRepoEditUrl
you will get links to edit the docs near each readme files.
type:
string
, default:master
The branch you want the edit links to send you to
type:
string
, default: ``
If the root folder is not at the root of your repo, use this parameter
type:
string
, default:Edit on github
