### Example Client Initialization and Resource Fetching

Source: https://github.com/opencloud-eu/opencloud/blob/main/vendor/github.com/lestrrat-go/httprc/v3/README.md

Demonstrates how to initialize an httprc client, configure it with options, start it, and add a new resource for asynchronous fetching. It shows how to handle potential errors and retrieve the fetched resource.

```go
package httprc_test

import (
  "context"
  "encoding/json"
  "fmt"
  "net/http"
  "net/http/httptest"
  "time"

  "github.com/lestrrat-go/httprc/v3"
)

func ExampleClient() {
  ctx, cancel := context.WithCancel(context.Background())
  defer cancel()

  type HelloWorld struct {
    Hello string `json:"hello"`
  }

  srv := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, _ *http.Request) {
    json.NewEncoder(w).Encode(map[string]string{"hello": "world"})
  }))

  options := []httprc.NewClientOption{
    // By default the client will allow all URLs (which is what the option
    // below is explicitly specifying). If you want to restrict what URLs
    // are allowed, you can specify another whitelist.
    //
    //		httprc.WithWhitelist(httprc.NewInsecureWhitelist()),
  }
  // If you would like to handle errors from asynchronous workers, you can specify a error sink.
  // This is disabled in this example because the trace logs are dynamic
  // and thus would interfere with the runnable example test.
  // options = append(options, httprc.WithErrorSink(errsink.NewSlog(slog.New(slog.NewJSONHandler(os.Stdout, nil)))))

  // If you would like to see the trace logs, you can specify a trace sink.
  // This is disabled in this example because the trace logs are dynamic
  // and thus would interfere with the runnable example test.
  // options = append(options, httprc.WithTraceSink(tracesink.NewSlog(slog.New(slog.NewJSONHandler(os.Stdout, nil)))))

  // Create a new client
  cl := httprc.NewClient(options...)

  // Start the client, and obtain a Controller object
  ctrl, err := cl.Start(ctx)
  if err != nil {
    fmt.Println(err.Error())
    return
  }
  // The following is required if you want to make sure that there are no
  // dangling goroutines hanging around when you exit. For example, if you
  // are running tests to check for goroutine leaks, you should call this
  // function before the end of your test.
  defer ctrl.Shutdown(time.Second)

  // Create a new resource that is synchronized every so often
  //
  // By default the client will attempt to fetch the resource once
  // as soon as it can, and then if no other metadata is provided,
  // it will fetch the resource every 15 minutes.
  //
  // If the resource responds with a Cache-Control/Expires header,
  // the client will attempt to respect that, and will try to fetch
  // the resource again based on the values obatained from the headers.
  r, err := httprc.NewResource[HelloWorld](srv.URL, httprc.JSONTransformer[HelloWorld]())
  if err != nil {
    fmt.Println(err.Error())
    return
  }

  // Add the resource to the controller, so that it starts fetching.
  // By default, a call to `Add()` will block until the first fetch
  // succeeds, via an implicit call to `r.Ready()`
  // You can change this behavior if you specify the `WithWaitReady(false)`
  // option.
  ctrl.Add(ctx, r)

  // if you specified `httprc.WithWaitReady(false)` option, the fetch will happen
  // "soon", but you're not guaranteed that it will happen before the next
  // call to `Lookup()`.
  // If you want to make sure that the resource is ready, you can call `Ready()` like so:
  /*
    {
      tctx, tcancel := context.WithTimeout(ctx, time.Second)
      defer tcancel()
      if err := r.Ready(tctx); err != nil {
        fmt.Println(err.Error())
        return
      }
    }
  */
  m := r.Resource()
  fmt.Println(m.Hello)
  // OUTPUT:
  // world
}
