Plugins usually add global-level functionality to VuePress. There is no strictly defined scope for a plugin - there are typically several types of plugins:
1. Extend the data generated at compile time. e.g. [@vuepress/plugin-last-updated](https://github.com/vuejs/vuepress/tree/next/packages/@vuepress/plugin-last-updated).
2. Generate extra files before or after compilation. e.g. [@vuepress/plugin-pwa](https://github.com/vuejs/vuepress/tree/next/packages/%40vuepress/plugin-pwa)
3. Add extra pages. e.g. [@vuepress/plugin-i18n-ui](https://github.com/vuejs/vuepress/tree/next/packages/@vuepress/plugin-i18n-ui)
4. Inject global UI. e.g. [@vuepress/plugin-back-to-top](https://github.com/vuejs/vuepress/tree/next/packages/%40vuepress/plugin-back-to-top).

A plugin should export a `plain object`(`#1`). If the plugin needs to take options, it can be a function that exports a plain object(`#2`). The function will be called with the plugin's options as the first argument, along with [context](#plugin-context) which provides some compile-time metadata.

::: tip Q & A
**Q**: Both `clientDynamicModules` and `enhanceAppFiles` can generate dynamic javascript code during build time, so what is the difference between the two?
**A**: The files generated by `clientDynamicModules` needs to be imported as `@dynamic/xxx` by the consumers themselves. But all the files generated by `enhanceAppFiles` will be loaded automatically when the APP is initialized on the client side.
