I dunno. We use a bunch of node specific APIs, but mostly in the default metrics. I guess you could omit them?

I've never used either Deno or Bun, so you'd have to tell us and potentially send PRs for changes needed 🙂

Yes, node and v8 specific default metrics can be omitted

@krutoo if you want to test my PR, that would be helpful: bun install siimon/prom-client#zb/bun.

@zbjornson @SimenB i see that Bun now partially implements perf_hooks:
https://bun.sh/docs/runtime/nodejs-apis#node-perf-hooks

But missing createHistogram and monitorEventLoopDelay.

When i try to use PromClient.collectDefaultMetrics In my Bun app i get error:

NotImplementedError: perf_hooks.monitorEventLoopDelay is not yet implemented in Bun.
 code: "ERR_NOT_IMPLEMENTED"

Yes, node and v8 specific default metrics can be omitted

@krutoo How? Is it documented anywhere? I want to omit metric by metric

@dawidsowardx I mean in my case I skip call PromClient.collectDefaultMetrics() and collect only custom metrics
