Clear documentation to setup non-TS project

[feryardiant]

Hi!

Firstly, thank you for your works for creating such a great extension. Secondly, I am not sure if it was an issue of this extension or is it just lack of documentation how to setup a non-TS project. as stated in the readme:

It's based on @vue/reactivity to calculate TypeScript on-demand to optimize performance similar to the native TypeScript language service.

I assume that this extension is mainly focus to bring great TypeScript support, but not really for non-TS one. Why?

Type hover

Here I just created 2 projects using npm init @vitejs/app command, one with --template vue and another one with --template vue-ts flag. Since it requires to have tsconfig.json or jsconfig.json in the root project, so I just copy the tsconfig.json from vite-app-ts project to vite-app and rename it to jsconfig.json. Then install the dependencies using pnpm

$> npm init @vitejs/app vite-app --template vue && cd vite-app && pnpm install
$> cd ..
$> npm init @vitejs/app vite-app-ts --template vue-ts && cd vite-app && pnpm install
$> cd ..
$> cp vite-app-ts/tsconfig.json vite-app/jsconfig.json

Take a look at src/components/HelloWorld.vue file from either projects and hover over the {{ msg }} on line 2. Notice that one on the vite-app shows Cannot find name 'msg'.ts(2304) and one on the vite-app-ts can show the correct property type.

Monorepo

Another issue I had is, for some reason it keep showing this message every time I opened a (monorepo) project where the vue app placed on website directory.

The issue still remain even after I add @vue/runtime-dom as devDependencies and in fact it is Vue 3 project, not Vue 2.

So

• Could you please explain why is it possible?
• For non-TS project, is it expected behaviour?
• Is it possible to make it behave exactly the same way as for TS?

Hi @feryardiant, regarding the goals of this project, you can see #168. You can understand it as close to the native TS development experience (capability and performance).

This 2 problems is also regressions, fixed in f17c4d9 (#319) and 8d24250.
