9.5.0-alpha.0

This is an alpha release that includes experimental functionality for the new logs API in Sentry. Support for these methods are only avaliable in the browser and core SDKs.

• feat(logs): Add experimental user-callable logging methods (#15442)

Logging is gated by an experimental option, _experiments.enableLogs.

Sentry.init({
  _experiments: {
    enableLogs: true,
  },
});

These API are exposed in the Sentry._experiment_log namespace.

On a high level, there are functions for each of the logging severity levels fatal, error, warn, info, debug, trace. There is also a log function that is an alias to info.

Sentry._experiment_log.info('Adding item to cart', { item: 'sneakers' });

If you want to do structured logging, you'll need to use the fmt helper exposed in the Sentry._experiment_log namespace.

const { fmt } = Sentry._experiment_log;

Sentry._experiment_log.info(fmt`user ${username} just bought ${item}!`);
