tracing
Val Town is a collaborative website to build and scale JavaScript apps.
Deploy APIs, crons, & store data – all from the browser, and deployed in milliseconds.
Enables Opentelemetry tracing for vals.
Exports two functions, init
and traced_handler
.
init
will set up opentelemetry.
For how to use it see this example val.
By default, traces log to the console but if you set HONEYCOMB_API_KEY
it'll also push the traces to honeycomb.
In the future we can add more export targets for other services. I'm also thinking about making a val to display them.
traced_handler
is a wrapper for your handler you can use on an HTTP val. Just pass it your HTTP function and export it as the default and it'll trace every request.
Here's a screenshot of what the honeycomb view of a trace from my connect playing val looks like.
