A small package that implements the NodeJS like Event Emitter API, which provides Node like event constructs in Go with support for generics.
Go 1.18 or newer version is required; the full documentation is at https://pkg.go.dev/github.com/ghoshRitesh12/govents
I think I wrote a banger of an article up at Hashnode; go check it out if interested.
A basic example:
package main
import (
"fmt"
"math/rand"
"time"
"github.com/ghoshRitesh12/govents"
)
func main() {
sample := govents.NewEventEmitter[int]()
strs := []string{}
sample.On("data", func(vals ...int) {
for _, val := range vals {
strs = append(strs, fmt.Sprintf("v%d", val))
}
fmt.Println("within eventListener", strs)
})
fmt.Println("outside eventListener", strs)
for range 4 {
time.Sleep(time.Second)
sample.Emit("data", rand.Intn(21), rand.Intn(21), rand.Intn(21))
}
}Output for the code above:
outside eventListener []
within eventListener [v12 v10 v11]
within eventListener [v12 v10 v11 v6 v6 v7]
within eventListener [v12 v10 v11 v6 v6 v7 v8 v18 v16]Some more examples can be found in the example directory.
