|
|
Fluux XMPP is a Go XMPP library, focusing on simplicity, simple automation, and IoT.
|
|
|
|
The goal is to make simple to write simple XMPP clients and components:
|
|
|
|
- For automation (like for example monitoring of an XMPP service),
|
|
- For building connected "things" by plugging them on an XMPP server,
|
|
- For writing simple chatbot to control a service or a thing.
|
|
- For writing XMPP servers components.
|
|
|
|
The library is designed to have minimal dependencies. For now, the library does not depend on any other library.
|
|
|
|

## Stanza subpackage
|
|
|
|
XMPP stanzas are basic and extensible XML elements. Stanzas (or sometimes special stanzas called 'nonzas') are used to
|
|
leverage the XMPP protocol features. During a session, a client (or a component) and a server will be exchanging stanzas
|
|
back and forth.
|
|
|
|
At a low-level, stanzas are XML fragments. However, Fluux XMPP library provides the building blocks to interact with
|
|
stanzas at a high-level, providing a Go-friendly API.
|
|
|
|
The `stanza` subpackage provides support for XMPP stream parsing, marshalling and unmarshalling of XMPP stanza. It is a
|
|
bridge between high-level Go structure and low-level XMPP protocol.
|
|
|
|
Parsing, marshalling and unmarshalling is automatically handled by Fluux XMPP client library. As a developer, you will
|
|
generally manipulates only the high-level structs provided by the stanza package.
|
|
|
|
The XMPP protocol, as the name implies is extensible. If your application is using custom stanza extensions, you can
|
|
implement your own extensions directly in your own application.
|
|
|
|
To learn more about the stanza package, you can read more in the
|
|
[stanza package documentation](https://github.com/FluuxIO/go-xmpp/blob/master/stanza/README.md).

## Examples
|
|
|
|
We have several [examples](https://github.com/FluuxIO/go-xmpp/tree/master/_examples) to help you get started using
|
|
Fluux XMPP library.
|
|
|
|
Here is the demo "echo" client:
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
"log"
|
|
"os"
|
|
|
|
"gosrc.io/xmpp"
|
|
"gosrc.io/xmpp/stanza"
|
|
)
|
|
|
|
func main() {
|
|
config := xmpp.Config{
|
|
Address: "localhost:5222",
|
|
Jid: "test@localhost",
|
|
Password: "test",
|
|
StreamLogger: os.Stdout,
|
|
Insecure: true,
|
|
}
|
|
|
|
router := xmpp.NewRouter()
|
|
router.HandleFunc("message", handleMessage)
|
|
|
|
client, err := xmpp.NewClient(config, router)
|
|
if err != nil {
|
|
log.Fatalf("%+v", err)
|
|
}
|
|
|
|
// If you pass the client to a connection manager, it will handle the reconnect policy
|
|
// for you automatically.
|
|
cm := xmpp.NewStreamManager(client, nil)
|
|
log.Fatal(cm.Run())
|
|
}
|
|
|
|
func handleMessage(s xmpp.Sender, p stanza.Packet) {
|
|
msg, ok := p.(stanza.Message)
|
|
if !ok {
|
|
_, _ = fmt.Fprintf(os.Stdout, "Ignoring packet: %T\n", p)
|
|
return
|
|
}
|
|
|
|
_, _ = fmt.Fprintf(os.Stdout, "Body = %s - from = %s\n", msg.Body, msg.From)
|
|
reply := stanza.Message{Attrs: stanza.Attrs{To: msg.From}, Body: msg.Body}
|
|
_ = s.Send(reply)
|
|
}
|
|
```
