Magical client-side logging – the little headers that could
In a server-side app, it's easy to find out what went wrong from logs. But what about the client side? The W3C's Reporting API, Content-Security-Policy, Network Error Logging (NEL), and the Reporting-Endpoints HTTP headers can let you know about all kinds of client-side issues that you might otherwise never see. Find out how to use them, monitor what they're up to, and solve all the issues that only your customers have been seeing!
