Bridgekeeper - HTTP Request Limiter and Retrier

Using Bridgekeeper

go get -u go.devnw.com/bk/v2@latest

Version 2 Changes

Version 2 changes the API for Bridgekeeper to using a direct function literal in the New function so that it can accept both the Do and RoundTrip functions from the http.Client and http.Transport respectively. This allows for Bridgekeeper to support connections where a custom http.Transport is may be required, for example, when using a custom TLS configuration.

HTTP Client Example

    client := bk.New(
        ctx, // Your application context
        http.DefaultClient.Do, // Your HTTP Client Do function (http.Client.Do)
        time.Millisecond, // Delay between requests
        5, // Retry count
        10, // Concurrent request limit
        http.DefaultClient.Timeout, // Request timeout
    )

    resp, err := client.Do(http.NewRequest(http.MethodGet, "localhost:5555"))
    if err != nil {
        log.Fatal(err)
    }

HTTP Round Tripper Example

    client := bk.New(
        ctx, // Your application context
        http.DefaultTransport.RoundTrip, // Your HTTP Transport
        time.Millisecond, // Delay between requests
        5, // Retry count
        10, // Concurrent request limit
        http.DefaultClient.Timeout, // Request timeout
    )

    resp, err := client.RoundTrip(http.NewRequest(http.MethodGet, "localhost:5555"))
    if err != nil {
        log.Fatal(err)
    }

NOTE: Bridgekeeper Returns a Do / RoundTrip Compliant HTTP Client
