#1210 7668337 Thanks @tdeekens! - Replace @sematext/gc-stats with prometheus-gc-stats.
The latter is better supported and doesn't require any userland install. The module however does not allow to full configuration of metric names. Hence the metric names have changed:
We now expose:

#1175 2da8d99 Thanks @tdeekens! - Remove support for Node.js v18
We didn't adjust functionality to remove support but changed the engines requirement.

All@promster/*packages are released using a fixed (synchronized) version across all of its packages. As a result you may see a higher version bump when updating than needed. For instance@promster/typeswill jump from v5 to v12 while it's actually one major increment with the changes listed below.

#1099 c3fbd90 Thanks @tdeekens! - Allow customization of individual metrics.
Previously we only allowed customizing a all histogram and percentile based metrics once with a buckets and percentiles option. This is too restrictive in cases in which you need to customize metrics individually.
As a result you can now pass metricBuckets and metricPercentiles as options. Both of which are a Record<string, number[]>. The key needs to match a an existing metric type.
This is a more elaborate example:
const middleware = createMiddleware({
app,
options: {
metricBuckets: {
httpRequestContentLengthInBytes: [
100000, 200000, 500000, 1000000, 1500000, 2000000, 3000000, 5000000,
10000000,
],
httpRequestDurationInSeconds: [
0.05, 0.1, 0.3, 0.5, 0.8, 1, 1.5, 2, 3, 10,
],
},
metricPercentiles: {
httpRequestDurationPerPercentileInSeconds: [0.5, 0.9, 0.95, 0.98, 0.99],
httpResponseContentLengthInBytes: [
100000, 200000, 500000, 1000000, 1500000, 2000000, 3000000, 5000000,
10000000,
],
},
},
});
If you used buckets or percentiles before you migrate the values into the structure above.
