DebugR

Receive debugging information alongside XMLHttpRequests.

Server code (example is php, but the extension is language agnostic): <?php if (isset($_SERVER['HTTP_DEBUGR'])) { // Only send headers when DebugR is enabled // Send a message alongside the request. header('DebugR: '.base64_encode('Hello DebugR')); // Append a unique label to send multiple messages. header('DebugR-my-first-label: '.base64_encode('Moarr information')); } ?> Client via javascript: window.addEventListener('message', function (e) { if (e.data.debugR) { console.log(e.data); } }, false); document.documentElement.setAttribute('data-debugR'); // Signal the extension that the eventlistener is active. Using debugr.js helper: <script src='js/debugr.js'></script> <script> debugR(function (message, details) { console.log(message); }); </script>
