๐ Progressive microservices framework for Go
Inspired and compatible with Moleculer JS
Simple, fast, light and fun to develop with. Also easy, very easy to test ;)
package main
import (
"fmt"
"github.com/moleculer-go/moleculer"
"github.com/moleculer-go/moleculer/broker"
)
type MathService struct {
}
func (s MathService) Name() string {
return "math"
}
func (s *MathService) Add(params moleculer.Payload) int {
return params.Get("a").Int() + params.Get("b").Int()
}
func (s *MathService) Sub(a int, b int) int {
return a - b
}
func main() {
var bkr = broker.New(&moleculer.Config{LogLevel: "error"})
bkr.Publish(&MathService{})
bkr.Start()
result := <-bkr.Call("math.add", map[string]int{
"a": 10,
"b": 130,
})
fmt.Println("result: ", result.Int())
//$ result: 140
bkr.Stop()
