Content
// Specify the variable types to infer the `c.get('metric')`:
type Variables = TimingVariables
const app = new Hono<{ Variables: Variables }>()
// add the middleware to your router
app.use(timing());
app.get('/', async (c) => {
// add custom metrics
setMetric(c, 'region', 'europe-west3')
// add custom metrics with timing, must be in milliseconds
setMetric(c, 'custom', 23.8, 'My custom Metric')
// start a new timer
startTime(c, 'db');
const data = await db.findMany(...);
// end the timer
endTime(c, 'db');
// ...or you can also just wrap a Promise using this function:
const data = await wrapTime(c, 'db', db.findMany(...));
return c.json({ response: data });
});
