Observability — Sentry & Source Maps
This lesson covers error monitoring with Sentry and using source maps for debugging in production.
Like a black box on a plane that records everything before an accident — Sentry records every production error with full details so you can fix it.
- Source maps
- Files that map minified/compiled code back to the original source for debugging.
- DSN
- Data Source Name — the unique address Sentry gives a project for sending events.
- Breadcrumbs
- A trail of actions the user took before an error — helps reproduce the bug.
