That command will generate code in `./src/client` and will use `axios` (the frontend HTTP library) internally.

### Try Out the Client Code

Now you can import and use the client code, it could look like this, notice that you get autocompletion for the methods:

<img src="/img/tutorial/generate-clients/image02.png">

	"fmt"
	"net/http"
	"net/url"
	"regexp"
	"strconv"
	"strings"
	"sync"
	"time"

	"github.com/minio/madmin-go/v3"
	"github.com/minio/minio/internal/bucket/replication"
	"github.com/minio/minio/internal/crypto"
	xhttp "github.com/minio/minio/internal/http"
)

//go:generate msgp -file=$GOFILE

// replicatedTargetInfo struct represents replication info on a target
type replicatedTargetInfo struct {

But the client/user will not see it. Instead, the client will receive an "Internal Server Error" with an HTTP status code `500`.

It should be this way because if you have a Pydantic `ValidationError` in your *response* or anywhere in your code (not in the client's *request*), it's actually a bug in your code.

And while you fix it, your clients/users shouldn't have access to internal information about the error, as that could expose a security vulnerability.

    So, it is a generator function that transfers the "generating" work to something else internally.

    By doing it this way, we can put it in a `with` block, and that way, ensure that the file-like object is closed after finishing.

/// tip

func getSRAddOptions(r *http.Request) (opts madmin.SRAddOptions) {
	opts.ReplicateILMExpiry = r.Form.Get("replicateILMExpiry") == "true"
	return
}

// SRPeerJoin - PUT /minio/admin/v3/site-replication/join
//
// used internally to tell current cluster to enable SR with
// the provided peer clusters and service account.
func (a adminAPIHandlers) SRPeerJoin(w http.ResponseWriter, r *http.Request) {
	ctx := r.Context()

For production you would use `fastapi run` instead. 🚀

Internally, **FastAPI CLI** uses <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a>, a high-performance, production-ready, ASGI server. 😎
