Config Reference
Basic Config
base
- Type:
string - Default:
/
The base URL to which the site will be deployed. You will need to set this if you plan to deploy your site under a sub path, for example GitHub pages. If you plan to deploy your site to https://foo.github.io/bar/, then base should be set to "/bar/". It should always start and end with a forward slash (/).
The base is automatically prepended to all the URLs that start with / in other options, so you only need to specify it once.
See also:
title
- Type:
string - Default:
undefined
Title for the site. This will be the prefix for all page titles, and displayed in the navbar in the default theme.
description
- Type:
string - Default:
undefined
Description for the site. This will be rendered as a <meta> tag in the page HTML.
head
- Type:
Array - Default:
[]
Extra tags to be injected to the page HTML <head>. Each tag can be specified in the form of [tagName, { attrName: attrValue }, innerHTML?]. For example, to add a custom favicon:
module.exports = {
head: [
['link', { rel: 'icon', href: '/logo.png' }]
]
}
host

Specify the host to use for the dev server.

TIP
Please be aware of GDPR (2018 reform of EU data protection rules) and consider setting Google Analytics to anonymize IPs where appropriate and/or needed.
serviceWorker
- Type:
boolean - Default:
false
If set to true, VuePress will automatically generate and register a service worker that caches the content for offline use (only enabled in production).
If developing a custom theme, the Layout.vue component will also be emitting the following events:
sw-readysw-cachedsw-updatedsw-offlinesw-error
PWA NOTES
The serviceWorker option only handles the service worker. To make your site fully PWA-compliant, you will need to provide the Web App Manifest and icons in .vuepress/public. For more details, see MDN docs about the Web App Manifest.
Also, only enable this if you are able to deploy your site with SSL, since service worker can only be registered under HTTPs URLs.
locales
- Type:
{ [path: string]: Object } - Default:
undefined
Specify locales for i18n support. For more details, see the guide on Internationalization.
shouldPrefetch
- Type:

() => true
A function to control what files should have <link rel="preload"> resource hints generated. See shouldPrefetch.
Theming

undefined
Specify this to use a custom theme. With the value of "foo", VuePress will attempt to load the theme component at node_modules/vuepress-theme-foo/Layout.vue.
themeConfig

{}
Provide config options to the used theme. The options will vary depending on the theme you are using.

md.set({ breaks: true })
md.use(require('markdown-it-xxx'))
}
}
}
Build Pipeline
Configuring CSS Pre-processors
VuePress comes with built-in webpack config for the CSS pre-processors listed below. For more information on installation these or pre-processors without built-in support, see Using Pre-Processors for more information.
postcss
- Type:
Object - Default:
{ plugins: [require('autoprefixer')] }
Options for postcss-loader. Note specifying this value will overwrite autoprefixer and you will need to include it yourself.
stylus

Options for stylus-loader.
scss
- Type:

less
- Type:

{}
Options for less-loader.
configureWebpack
- Type:
Object | Function - Default:
undefined
Modify the internal webpack config. If the value is an Object, it will be merged into the final config using webpack-merge; If the value is a function, it will receive the config as the 1st argument and an isServer flag as the 2nd argument. You can either mutate the config directly, or return an object to be merged:
module.exports = {
configureWebpack: (config, isServer) => {
if (!isServer) {
// mutate the config for client
}
}
}
chainWebpack
- Type:
Function - Default:
undefined
Modify the internal webpack config with webpack-chain.
module.exports = {
chainWebpack: (config, isServer) => {
// config is an instance of ChainableConfig
}
}
Browser Compatibility
evergreen
- Type:
boolean - Default:
false
Set to true if you are only targeting evergreen browsers. This will disable ES5 transpilation and polyfills for IE, and result in faster builds and smaller files.
