What is your .prettierrc file content?
And vetur.useWorkspaceDependencies?

[richex-cn]

The vetur.useWorkspaceDependencies is true, and the .prettierrc.js file of the current workspace is as follows:

module.exports = {
  tabWidth: 2,
  printWidth: 80,
  semi: false,
  singleQuote: true,
  proseWrap: 'preserve',
  requirePragma: false,
  bracketSpacing: true,
  arrowParens: 'avoid',
  trailingComma: 'none'
}

@richex-cn Can you try to use this vsix?
vetur-0.30.1.vsix.zip
https://github.com/vuejs/vetur/blob/master/docs/FAQ.md#install-an-old-version-of-vetur

[richex-cn]

@yoyo930021 Before installation, I uninstalled this extension and deleted the %USERPROFILE%\.vscode\extensions\octref.vetur-0.30.1\ directory. Then run code.exe --install-extension vetur-0.30.1.vsix through the command line to open VSCode, and I don't see the Vetur extension in the plug-in list, the same is true for restarting VSCode.

So I using the Install from VSIX command in the Extensions view command drop-down, And completed the installation of the Vetur extension. But this problem still exists.

I tried to clone the project on another device, but this problem did not occur. After trying for a while, I found that setting vetur.useWorkspaceDependencies to true will cause the problem to appear, so it should be the library introduced by the plugin or I introduced The library is caused by a problem.

This is a minimal repro case:

I just started experiencing this issue after all formatting was working correctly all day.

Suddenly on save now it's deleting the contents of <template lang="pug">. Very frustrating for this issue to randomly appear.

I can confirm that downgrading to vetur 0.29.1 fixes the issue and deletion no longer occurs during save/format. This indicates the problem was introduced with the later vetur versions & releases.

@IvanCaceres You can try the way I mentioned above, if you still can't solve it, you can communicate with @yoyo930021 .

I will close searching plugin feature and use found lib from vetur in next version.

[yoyo930021]

Ha, I found the problem.
In your project, it have a prettier lib but version is 1.x.x.
This version don't support plugin.

In next version, vetur use bundled prettier in this case.
