Info

Platform: Linux
Vetur version: 0.11.7
VS Code version: 1.21.1

Problem

When checkJs is set to true in tsconfig.json or jsconfig.json and a .vue file which modifies a watched value is opened, Vetur crashes.

Vetur crashing on files like this is almost identical to https://github.com/vuejs/vetur/issues/191#issuecomment-300405883

There is no output from Vue Language Server as it appears to crash. However, there is output from the Window log:

Reproducible Case

Open nextgensparx/veturpack in VS Code and then client/components/Test.vue.

It's worth noting that if data2 is changed to data3 in watch, the issue goes away.

Thanks for reporting. I guess this problem comes from TS server.

I will investigate more and report issue to related team.

Boiled down version：

func.ts

interface ComponentOptions<V> {
  watch: Record<string, WatchHandler<any>>;
}
type WatchHandler<T> = (val: T) => void;
declare function extend(options: ComponentOptions<{}>): void;
export var vextend = extend

import {vextend} from './func'
// hover on vextend
export var a = vextend({
  watch: {
    data1(val) {
      this.data2 = 1
    },
    data2(val) { }
  }
})

tsconfig.json

{
  "compilerOptions": {
    "checkJs": true,
    "allowJs": true
  }
}

This issue has already been tracked in https://github.com/Microsoft/TypeScript/issues/23198.

Let's patiently await TS team's fix. Meanwhile we cannot do much in Vue side, so I will close this issue for now.

HerringtonDarkholme on 9 Apr 2018

@HerringtonDarkholme Can this be fixed now that https://github.com/Microsoft/TypeScript/issues/23198 has been closed? The latest version of Vetur (0.16.2) still crashes on the reproduction repository mentioned above.
