Problem

when project with jsconfig.json has path alias, .vue intellisense is slow, *.js normal.

{
  "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "@/*": ["./src/@/*"],
       ...other 5 path maps,
      "$public/*": ["./src/$public/*"]
    }
  },
  "exclude": [
    "node_modules"
  ]
}

Reproducible Case

.vue

.js

I have the same situation using TypeScript with my tsconfig.json. It seems like the more aliases I have, the slower it gets.

I setup path-mappings a few days ago. Since then, Vetur is really slow.

It seems like Vetur is having a queue with file-states to analyze: If i start typing something like long_word, i can often see errors like:

'lon' is unknown
'long_' is unknown ( a few seconds later)
'long_wor' is unknown (more seconds later)

I’ll create a reproduction repository in the next few days.
