# http-client

Simple golang package with fasthttp client and prometheus metric.

## Example NewWithMetric

```go

// metric

var netSourcesLatencyHistogram = func() *prometheus.HistogramVec {

    var metric = prometheus.NewHistogramVec(

        prometheus.HistogramOpts{

            Namespace: "service",

            Subsystem: "net",

            Name:      "sources_latency",

            Help:      "Third party response latency histogram.",

            Buckets:   prometheus.ExponentialBuckets(0.05, 2, 8),

        }, []string{"source"})

    prometheus.MustRegister(metric)

    return metric

}()

// create

client := httpclient.NewWithMetric("domain", netSourcesLatencyHistogram)

// request

if err := p.client.DoTimeout(req, resp); err != nil {

    // error handling

}

```

## Example NewWithMetricFunc

```golang

// metric func

var latencyFunc = func(start time.Time, domain string) {

    latencyMetric.WithLabelValues(domain).Observe(float64(time.Since(start).Nanoseconds()) / 1000000)

}

// func

client := httpclient.NewWithMetricFunc("domain", latencyFunc)

// request

if err := p.client.DoTimeout(req, resp); err != nil {

    // error handling

}

```
