# 🤓 Usage
17+
18+
Using without websocket:
19+
20+
```golang
21+
package main
22+
23+
import (
24+
"fmt"
25+
)
26+
27+
func main() {
28+
// User ID here 👇
29+
res := FetchUser("331846231514939392")
30+
31+
// handle presence data here
32+
fmt.Println(res.Data.DiscordStatus)
33+
}
34+
```
35+
36+
Using with websocket:
37+
38+
```golang
39+
package main
40+
41+
import (
42+
"fmt"
43+
"os"
44+
"os/signal"
45+
"syscall"
46+
47+
"github.com/barbarbar338/go-lanyard"
48+
)
49+
50+
func main() {
51+
// User ID here 👇
52+
ws := lanyard.CreateWS("331846231514939392", func(data *LanyardData) {
53+
54+
// handle presence data here
55+
fmt.Println(data.DiscordStatus)
56+
})
57+
58+
sc := make(chan os.Signal, 1)
59+
signal.Notify(
60+
sc,
61+
syscall.SIGINT,
62+
syscall.SIGTERM,
63+
os.Interrupt,
64+
)
65+
<-sc
66+
67+
fmt.Println("Closing client.")
68+
69+
// destroy ws before exit
70+
ws.Destroy()
71+
}
72+
```
