Configuration
Config File
The essential file for configuring a VuePress site is .vuepress/config.js, while TypeScript config file is also supported. You can use .vuepress/config.ts instead to get better types hint for VuePress config.
To be more specific, we have a convention for config file paths (in order of precedence):
- In current working directory 
cwd:vuepress.config.tsvuepress.config.jsvuepress.config.mjs
 - In source directory 
sourceDir:.vuepress/config.ts.vuepress/config.js.vuepress/config.mjs
 
You can also specify the config file via --config option of CLI:
vuepress dev docs --config my-config.tsA basic config file looks like this:
import { viteBundler } from '@vuepress/bundler-vite'
import { defaultTheme } from '@vuepress/theme-default'
import { defineUserConfig } from 'vuepress'
export default defineUserConfig({
  bundler: viteBundler(),
  theme: defaultTheme(),
  lang: 'en-US',
  title: 'Hello VuePress',
  description: 'Just playing around',
})Tips

Client Config File
In most cases, the config file is sufficient to configure your VuePress site. However, sometimes users may want to add some client-side code directly. To help with this, VuePress also supports a client config file:
├─ docs
│  ├─ .vuepress
│  │  ├─ client.js   <--- client config file
│  │  └─ config.js   <--- config file
│  └─ README.md
├─ .gitignore
└─ package.jsonSimilarly, we also have a convention for client config file paths (in order of precedence):
- In current working directory 
cwd:vuepress.client.tsvuepress.client.jsvuepress.client.mjs
 - In source directory 
sourceDir:.vuepress/client.ts.vuepress/client.js.vuepress/client.mjs
 
A basic client config file looks like this:
import { defineClientConfig } from 'vuepress/client'
export default defineClientConfig({
  enhance({ app, router, siteData }) {},
  setup() {},
  rootComponents: [],
})Tips
Unlike config file, client config file could not be specified via CLI options.
