 | logVerbosity      | string   | The verbosity level of the information printed in the log by `tsserver`. Accepts values: `"off"`, `"terse"`, `"normal"`, `"requesttime"`, `"verbose"`. **Default**: `undefined` (`"off"`).                                                                                         |
 | maxTsServerMemory | number   | The maximum size of the V8's old memory section in megabytes (for example `4096` means 4GB). The default value is dynamically configured by Node so can differ per system. Increase for very big projects that exceed allowed memory usage. **Default**: `undefined` |
 | npmLocation       | string   | Specifies the path to the NPM executable used for Automatic Type Acquisition. |
+| locale            | string   | The locale to use to show error messages. |
 | plugins           | object[] | An array of `{ name: string, location: string }` objects for registering a Typescript plugins. **Default**: []                                                                                                                                                         |
