How to stop Vuter from removing trailing (dangling) commas

• I have searched through existing issues
• I have read through docs
• I have read FAQ

Info

• Platform: macOS
• Vetur version: 0.21.0
• VS Code version: 1.34.0

Problem

When I save a .vue file all trailing commas will be removed. [

I’ve tried multiple Vetur › Format › Default Formatter: HTML settings and js-beautify-html get the closest to how I like to write code. (please don’t write comments telling me why trailing commas are bad)

Reproducible Case

1. Get vscode
2. install Vuter
3. Save a .vue file with trailing commas

I am having this exact same issue. I use prettier+eslint (with .eslintrc) and prettier works just find on .js files and respects eslint rules. But for some reason vetur, even with the "vetur.format.defaultFormatter.js": "prettier-eslint", setting on, removes my trailing commas. The only fix I found is to manually set prettier config options. I do feel this is some sort of bug because the only thing vetur seems to get wrong is the trailing commas. Otherwise it seems to format just fine.

{
  "vetur.format.defaultFormatterOptions": {
    "prettier": {
      "trailingComma": "all"
    }
  }
}

You can set VSCode setting.

"vetur.format.defaultFormatter.js": "prettier",
"vetur.format.defaultFormatter.ts": "prettier"

if use prettier, you can set prettier config. .prettierrc at project root.

{
  trailingComma: 'none'
}
