it's hard for developer to write a common component with vue-demi

【description】: I want to try create the same component for Vue2 & Vue3 in the same source code, so I find vue-demi. But… I have seen some projects likes json-editor-vue. For compact Vue2 & Vue3, I found its source code write render options for 2 & 3. But i think it’s hard for developer to code.

I prefer to code in template in a sfc file. So i have some idea(We can smooth the difference with Vue2 & Vue3 when we compile components). Can we write a component with setup & composition-api in a sfc. And then when we compile the component, we can use a series of plugins for Vue2: unplugin-auto-import, unplugin-vue2-script-setup, vite-plugin-vue2, vue-template-compiler@2.6.x, and plugins for Vue3: @vitejs/plugin-vue.

@antfu Maybe u have thought some idea before create this repo. So can u give me some advice or info?

@Hisioni can you share your vue-demi repo? If it possible

Of course, in this repository, still have question, i don’t know how to config to generate d.ts on every vue version

Use unbuild for shipping the component directly
