modify-file-warning README

Useful when modify file under node_modules accidentally.

Settings

{
  // will give a warning is file match the includedFileGlobs
  "modifyFileWarning.includedFileGlobs": [
    "**/node_modules/**/*"
    // "**/.git/**"
  ],
  // you can using this setting to exclude files from includedFileGlobs
  "modifyFileWarning.excludedFileGlobs": []
}

Why not automatically set file readonly but choose to warn?

VSCode doesn't provide an api to mark a opened editor readonly now, ref: Add read-only mode.
