Azure Functions (JavaScript) error tracking

Your function runs on Azure. Your error reports don’t have to. Use the Sentry Node.js SDK to send them to Telebugs on your server.

~/hoofnotes  npm install @sentry/node
~/hoofnotes  nvim save-note/index.js
const Sentry = require("@sentry/node");
const { saveNote } = require("../hoofnotes/notes");
Sentry.init({
// Copy the complete Telebugs DSN, key and path included.
dsn: "YOUR_TELEBUGS_DSN",
});
module.exports = async function (context, req) {
try {
context.res = await saveNote(req);
} catch (error) {
Sentry.captureException(error);
await Sentry.flush(2000);
throw error;
}
};
~/hoofnotes  func start

Hang on, I already use Sentry

Keep @sentry/node and change its destination to your Telebugs DSN. Your error reports stay on your server. You don’t need a Sentry account.

What about errors caught inside the function?

You can report them explicitly through the Node.js SDK. The function must allow time for delivery before it ends; Telebugs then keeps the error and its backtrace.

Does self-hosting mean leaving Azure?

No. Keep the function on Azure and make your Telebugs endpoint reachable from it. You choose where the error reports are stored.
