Error logging with Sentry
The Starter App supports error logging with Sentry out of the box provided that required environment variables are set in place. Other logging solutions can also be used but the Sentry client comes already strapped into the Starter App.
To enable the Sentry error logging a DSN, Data Source Name has to be provided as an environment variable. Browser and Node environments both require their own keys. The key names are as follows:
- SERVER_SENTRY_DSN - the private Sentry DSN, used on the server side
- REACT_APP_PUBLIC_SENTRY_DSN - the public Sentry DSN, used in the browser
The DSN keys can be aquired from the Sentry project settings. To test them in your local environment
they can be passed for example to the yarn run dev-server command:
REACT_APP_PUBLIC_SENTRY_DSN='<public-sentry-dsn>' SERVER_SENTRY_DSN='<private-sentry-dsn>' yarn run dev-server
If the Sentry DSN keys are not provided Starter App will log errors to the console. The logging and Sentry setup is implemented in util/log.js and server/log.js so refer to those files to change the external logging service or the logging logic in general.
