Incluí un componente vue3 con rollup. El componente es sencillo:

 // main.vue <template> <div> <div @click="clickDiv">{{ 1 }}</div> <div ref="divRef"></div> </div> </template> <script> import { onMounted, ref, defineComponent } from 'vue' export default defineComponent({ name: 'Vue3Component', mounted () { console.log('component mounted') // it works well }, setup() { const divRef = ref() const clickDiv = () => { console.log('divRef', divRef) // it causes some warnings } onMounted(() => { console.log('component onMounted') // it causes some warnings }) return { a: ref(1), clickDiv, divRef } }, }) </script>

y la entrada de entrada:

 // index.js import Vue3Component from './main.vue' Vue3Component.install = (app) => { app.component(Vue3Component.name, Vue3Component) } export { Vue3Component }

código de configuración acumulada:

 // rollup.config.js import resolve from '@rollup/plugin-node-resolve' import commonjs from '@rollup/plugin-commonjs' import pkg from './package.json' import external from 'rollup-plugin-peer-deps-external' import vuePlugin from 'rollup-plugin-vue' const extensions = ['.vue', '.js'] const globals = { vue: 'Vue', 'highlight.js': 'hljs', 'marked': 'marked' } export default [ { input: 'src/index.js', output: [ { name: 'VueNextMEditor', file: pkg.main, format: 'umd', globals }, { file: pkg.module, format: 'es' }, { name: 'VueNextMEditor', file: pkg.unpkg, format: 'umd', plugins: [terser()], globals } ], plugins: [ external(), vuePlugin(), resolve(), commonjs({ extensions }) ] } ]

Cuando pruebo el componente localmente con vue-cli, onMounted en la configuración no funciona. El navegador muestra un error como este:

 [Vue warn]: onMounted is called when there is no active component instance to be associated with. Lifecycle injection APIs can only be used during execution of setup(). If you are using async setup(), make sure to register lifecycle hooks before the first await statement.

 [Vue warn]: Missing ref owner context. ref cannot be used on hoisted vnodes. A vnode with ref must be created inside the render function. at <Vue3Component> at <App>

Pero mounted fuera de la función de configuración funcionará. ¿Alguien puede ayudarme a resolver este problema? Vue3Component
