vite-plugin-vue-layouts
Router based layout for Vue 3 applications using Vite
Overview
This works best along with the vite-plugin-pages.
Layouts are stored in the /src/layouts
folder by default and are standard Vue components with a <router-view></router-view>
in the template.
Pages without a layout specified use default.vue
for their layout.
You can use route blocks to allow each page to determine its layout. The block below in a page will look for /src/layouts/users.vue
for its layout.
See the Vitesse starter template for a working example.
<route lang="yaml">
meta:
layout: users
</route>
Getting Started
Install Layouts:
$ npm install -D vite-plugin-vue-layouts
Add to your vite.config.js
:
import Vue from '@vitejs/plugin-vue';
import Pages from 'vite-plugin-pages';
import Layouts from 'vite-plugin-vue-layouts';
export default {
plugins: [Vue(), Pages(), Layouts()],
};
In main.ts, you need to add a few lines to import the generated code and setup the layouts.
import { createRouter } from 'vue-router'
import { setupLayouts } from 'virtual:generated-layouts'
import generatedRoutes from 'virtual:generated-pages'
const routes = setupLayouts(generatedRoutes)
const router = createRouter({
// ...
routes,
});
Client Types
If you want type definition of virtual:generated-layouts
, add vite-plugin-vue-layouts/client
to compilerOptions.types
of your tsconfig
:
{
"compilerOptions": {
"types": ["vite-plugin-vue-layouts/client"]
}
}
Configuration
interface UserOptions {
layoutsDirs?: string | string[]
exclude: string[]
defaultLayout?: string
}
Using configuration
To use custom configuration, pass your options to Layouts when instantiating the plugin:
// vite.config.js
import Layouts from 'vite-plugin-vue-layouts';
export default {
plugins: [
Layouts({
layoutsDirs: 'src/mylayouts',
defaultLayout: 'myDefault'
}),
],
};
layoutsDirs
Relative path to the layouts directory. Supports globs. All .vue files in this folder are imported async into the generated code.
Can also be an array of layout dirs
Any files named __*__.vue
will be excluded, and you can specify any additional exclusions with the exclude
option
Default: 'src/layouts'
How it works
setupLayouts
transforms the original router
by
- Replacing every page with its specified layout
- Appending the original page in the
children
property.
Simply put, layouts are nested routes with the same path.
Before:
router: [ page1, page2, page3 ]
After setupLayouts()
:
router: [
layoutA: page1,
layoutB: page2,
layoutA: page3,
]
That means you have the full flexibility of the vue-router API at your disposal.
Common patterns
Transitions
Layouts and Transitions work as expected and explained in the vue-router docs only as long as Component
changes on each route. So if you want a transition between pages with the same layout and a different layout, you have to mutate :key
on <component>
(for a detailed example, see the vue docs about transitions between elements).
App.vue
<template>
<router-view v-slot="{ Component, route }">
<transition name="slide">
<component :is="Component" :key="route" />
</transition>
</router-view>
</template>
Now Vue will always trigger a transition if you change the route.
Data from layout to page
If you want to send data down from the layout to the page, use props
<router-view foo="bar" />
Set static data at the page
If you want to set state in your page and do something with it in your layout, add additional properties to a route's meta
property. Doing so only works if you know the state at build-time.
You can use the <route>
block if you work with vite-plugin-pages.
In page.vue
:
<template><div>Content</div></template>
<route lang="yaml">
meta:
layout: default
bgColor: yellow
</route>
Now you can read bgColor
in layout.vue
:
<script setup>
import { useRouter } from 'vue-router'
</script>
<template>
<div :style="`background: ${useRouter().currentRoute.value.meta.bgColor};`">
<router-view />
</div>
</template>
Data dynamically from page to layout
If you need to set bgColor
dynamically at run-time, you can use custom events.
Emit the event in page.vue
:
<script setup>
import { defineEmit } from 'vue'
const emit = defineEmit(['setColor'])
if (2 + 2 === 4)
emit('setColor', 'green')
else
emit('setColor', 'red')
</script>
Listen for setColor
custom-event in layout.vue
:
<script setup>
import { ref } from 'vue'
const bgColor = ref('yellow')
const setBg = (color) => {
bgColor.value = color
}
</script>
<template>
<main :style="`background: ${bgColor};`">
<router-view @set-color="setBg" />
</main>
</template>
ClientSideLayout
The clientSideLayout uses a simpler virtual file + glob import scheme, This means that its hmr is faster and more accurate, but also more limited
Usage
// vite.config.js
import { ClientSideLayout } from 'vite-plugin-vue-layouts'
export default {
plugins: [
ClientSideLayout({
layoutsDir: 'src/mylayouts', // default to 'src/layout'
defaultLayout: 'myDefault', // default to 'default', no need '.vue'
importMode: 'sync' // The default will automatically detect -> ssg is sync,other is async
}),
],
};
