 - `publicPath` (`string`): Emits absolute URLs with public path prefix, e.g. `https://example.com/project/`.
 - `fileContext` (`string`): Makes the `[file]` argument relative to this directory.
 - `sourceRoot` (`string`): Provide a custom value for the `sourceRoot` property in the SourceMap.
+- `debugIds` (`boolean`): If `true`, unique ids will be emitted in source and sourcemaps which streamlines identifying sourcemaps across different builds. See the [TC39 sourcemap debug ID proposal(https://github.com/tc39/ecma426/blob/main/proposals/debug-id.md) for more details.
 
 The `fileContext` option is useful when you want to store source maps in an upper level directory to avoid `../../` appearing in the absolute `[url]`.
