Vue2

The bad news is that for jsx syntax support, you can't use it with jsx-vue2 because it doesn't support props that start with _. Click issues to learn more. The good news is that there are no problems with using babel-plugin-transform-vue-jsx.

jsx example

// main.ts
import Vue from 'vue';
import VueSource from 'unplugin-vue-source/vue';
import App from './App.vue';

Vue.use(VueSource);

new Vue({
  el: '#app',
  render: (h) => h(App),
});

Vue3

// main.ts
import { createApp } from 'vue';
import VueSource from 'unplugin-vue-source/vue';
import App from './App.vue';

const app = createApp(App);
app.use(VueSource);
app.mount('#app');

Plugins

You need to make sure that VueSource is executed before vue compiles the plugin for execution.

Vite

// vite.config.ts
import VueSource from 'unplugin-vue-source/vite';

export default defineConfig({
  plugins: [
    VueSource({
      /* options */
    }),
    // other plugins
  ],
});

Rollup

// rollup.config.js
import VueSource from 'unplugin-vue-source/rollup';

export default {
  plugins: [
    VueSource({
      /* options */
    }),
    // other plugins
  ],
};

Webpack

// webpack.config.js
module.exports = {
  plugins: [
    require('unplugin-vue-source/webpack')({
      /* options */
    }),
    // other plugins
  ],
};

Rspack

// rspack.config.js
module.exports = {
  plugins: [
    require('unplugin-vue-source/rspack')({
      /* options */
    }),
    // other plugins
  ],
};

Vue CLI

// vue.config.js
module.exports = {
  configureWebpack: {
    plugins: [
      require('unplugin-vue-source/webpack')({
        /* options */
      }),
      // other plugins
    ],
  },
};

esbuild

// esbuild.config.js
import { build } from 'esbuild';
import VueSource from 'unplugin-vue-source/esbuild';

build({
  plugins: [
    VueSource({
      /* options */
    }),
    // other plugins
  ],
});
