      • logLevel

      • Type: 'info' | 'warn' | 'error' | 'silent'
      • Default: 'info'
      • Version: >= 1.4.0

      Sets the Rsbuild log level. Defaults to info.

      Tip

      This option also affects Rsbuild's log output in the browser. You can override this behavior through the client.logLevel option.

      Example

      When logLevel is set to warn, Rsbuild only outputs warning and error logs:

      rsbuild.config.ts
      export default {
  logLevel: 'warn',
};

      When logLevel is set to error, Rsbuild only outputs error logs:

      rsbuild.config.ts
      export default {
  logLevel: 'error',
};

      Optional values

      • info: Output all logs.
      • warn: Output warning and error logs.
      • error: Output error logs.
      • silent: Do not output any logs.
      Note

      In debug mode, Rsbuild always outputs all logs.

      Limitations

      Rsbuild currently cannot set different log levels for its built-in logger per instance because all instances share a global logger.

      If you need an isolated logger in custom code or plugins, use createLogger to create a separate logger instance instead of mutating the shared singleton.
