@astrojs/vue

This Astro integration enables server-side rendering and client-side hydration for your Vue 3 components.

Installation

There are two ways to add integrations to your project. Let’s try the most convenient option first!

`astro add` command

Astro includes a CLI tool for adding first party integrations: astro add. This command will:

(Optionally) Install all necessary dependencies and peer dependencies
(Also optionally) Update your astro.config.* file to apply this integration

To install @astrojs/vue, run the following from your project directory and follow the prompts:

# Using NPM
npx astro add vue
# Using Yarn
yarn astro add vue
# Using PNPM
pnpm astro add vue

If you run into any issues, feel free to report them to us on GitHub and try the manual installation steps below.

Install dependencies manually

First, install the @astrojs/vue integration like so:

npm install @astrojs/vue

Most package managers will install associated peer dependencies as well. Still, if you see a “Cannot find package ‘vue’” (or similar) warning when you start up Astro, you’ll need to install Vue:

npm install vue

Now, apply this integration to your astro.config.* file using the integrations property:

import { defineConfig } from 'astro/config';
import vue from '@astrojs/vue';

export default defineConfig({
  // ...
  integrations: [vue()],
  //             ^^^^^
});

Getting started

To use your first Vue component in Astro, head to our UI framework documentation. You’ll explore:

📦 how framework components are loaded,
💧 client-side hydration options, and
🤝 opportunities to mix and nest frameworks together

Options

This integration is powered by @vitejs/plugin-vue. To customize the Vue compiler, options can be provided to the integration. See the @vitejs/plugin-vue docs for more details.

import { defineConfig } from 'astro/config';
import vue from '@astrojs/vue';

export default defineConfig({
  // ...
  integrations: [
    vue({
      template: {
        compilerOptions: {
          // treat any tag that starts with ion- as custom elements
          isCustomElement: (tag) => tag.startsWith('ion-'),
        },
      },
      // ...
    }),
  ],
});

appEntrypoint

You can extend the Vue app instance setting the appEntrypoint option to a root-relative import specifier (for example, appEntrypoint: "/src/pages/_app").

The default export of this file should be a function that accepts a Vue App instance prior to rendering, allowing the use of custom Vue plugins, app.use, and other customizations for advanced use cases.

import { defineConfig } from 'astro/config';
import vue from '@astrojs/vue';

export default defineConfig({
  integrations: [vue({ appEntrypoint: '/src/pages/_app' })],
});

import type { App } from 'vue';
import i18nPlugin from 'my-vue-i18n-plugin';

export default (app: App) => {
  app.use(i18nPlugin);
};

jsx

You can use Vue JSX by setting jsx: true.

import { defineConfig } from 'astro/config';
import vue from '@astrojs/vue';

export default defineConfig({
  integrations: [vue({ jsx: true })],
});

This will enable rendering for both Vue and Vue JSX components. To customize the Vue JSX compiler, pass an options object instead of a boolean. See the @vitejs/plugin-vue-jsx docs for more details.

import { defineConfig } from 'astro/config';
import vue from '@astrojs/vue';

export default defineConfig({
  integrations: [
    vue({
      jsx: {
        // treat any tag that starts with ion- as custom elements
        isCustomElement: (tag) => tag.startsWith('ion-'),
      },
    }),
  ],
});
