Convert existing js to ts?

[goforu]

I have an existing quasar project coding in javascript. To take advantage of Typescript feature, I want to add typescript to my existing project. Unfortunately, I have tons of vue files to rewrite. Is there a better way to do that? For say like use both js and ts in project or a batch ts converter?

Qv1(Vue2) or Qv2(Vue3)?

I did find this article how to convert a Vue3 CLI app from JS to TS ( See the Add TypeScript Support part):
https://www.thisdot.co/blog/your-first-vue-3-app-using-typescript

And this repo and article ( a bit older for Vue2):
https://johnpapa.net/vue-typescript/

THANKS for your answer. Very appreciated. But I found the article may not handle my case. For one thing, the article's adding TS support is targeting Vue 2 which is class-based. When it comes to Vue 3 it has refactored by pure hand. For another, the converting from js to ts only applies for files with certain file extension, etc js. While ts inside vue files remains untouched.

If you find something better than convert by hand, let us know!
