        "options": {
          "run": "onType",
          "configPath": null,
          "tsConfigPath": null,
          "unusedDisableDirectives": "allow",
          "typeAware": false,
          "flags": {}
        }
      }
    }
  }
}

Below are the available values and descriptions for each option:

Option Key	Value(s)	Default	Description
run	"onSave" | "onType"	"onType"	Should the server lint the files when the user is typing or saving
configPath	<string> | null	null	Path to a oxlint configuration file, passing a string will disable nested configuration
tsConfigPath	<string> | null	null	Path to a TypeScript configuration file. If your tsconfig.json is not at the root, alias paths will not be resolve correctly for the import plugin
unusedDisableDirectives	"allow" | "warn" | "deny"`	"allow"	Define how directive comments like // oxlint-disable-line should be reported, when no errors would have been reported on that line anyway
typeAware	true | false	false	Enables type-aware linting
flags	Map<string, string>	<empty>	Special oxc language server flags, currently only one flag key is supported: disable_nested_config
