VS Code auto save afterDelay w/Prettier not working-CodePudding

VS Code version: 1.64.2
Prettier Extension version: 9.2.0

I want it so Prettier runs on auto save, which should be every 500 milliseconds. I have the following in my workspace JSON:

{
  "editor.formatOnSave": true,
  "editor.defaultFormatter": null,
  "[javascript]": {
    "editor.defaultFormatter": "esbenp.prettier-vscode",
  },
  "prettier.trailingComma": "all",
  "files.autoSave": "afterDelay",
  "files.autoSaveDelay": 500
}

And the same in my user JSON:

{
  "workbench.colorTheme": "Darcula",
  "workbench.iconTheme": "material-icon-theme",
  "editor.formatOnSave": true,
  "editor.defaultFormatter": null,
  "[javascript]": {
    "editor.defaultFormatter": "esbenp.prettier-vscode"
  },
  "prettier.trailingComma": "all",
  "files.autoSave": "afterDelay",
  "files.autoSaveDelay": 500
}

Note: That's the entirety of both JSON files. No other formatters are listed in the settings.

And the following test snippet:

let                    = "blah"

But nothing is happening. The file - which has been saved to the file system previously - isn't saving in the current state after 500 milliseconds, so Prettier isn't running.

I'm at a loss, and any help would be greatly appreciated.

EDIT: A manual save (e.g., ctrl s) has the following output:

No errors

CodePudding user response：

Going by this answer, the editor cannot format on save when the afterDelay option is selected. It has to be either onFocusChange or onWindowChange.

As an example, a user level JSON file that looks like this will work. It will automatically save and format the file when focus is taken off the editor (by, say, clicking on another open file):

{
  "editor.formatOnSave": true,
  "editor.defaultFormatter": null,
  "[javascript]": {
    "editor.defaultFormatter": "esbenp.prettier-vscode"
  },
  "files.autoSave": "onFocusChange",
}
