Description
Goflow is a simply package to control goroutines execution order based on dependencies. It works similar to async.auto from node.js async package, but for Go.

queue
Gives you a sync.WaitGroup like queue group accessibility. Helps you to throttle and limit goroutines, wait for the end of the all goroutines and much more. -

Goflow
Goflow is a simply package to control goroutines execution order based on dependencies. It works similar to async.auto from node.js async package, but for Go.
Install
Install the package with:
go get github.com/kamildrazkiewicz/go-flow
Import it with:
import "github.com/kamildrazkiewicz/go-flow"
and use goflow as the package name inside the code.
Example
package main
import (
"fmt"
"github.com/kamildrazkiewicz/go-flow"
"time"
)
func main() {
f1 := func(r map[string]interface{}) (interface{}, error) {
fmt.Println("function1 started")
time.Sleep(time.Millisecond * 1000)
return 1, nil
}
f2 := func(r map[string]interface{}) (interface{}, error) {
time.Sleep(time.Millisecond * 1000)
fmt.Println("function2 started", r["f1"])
return "some results", nil
}
f3 := func(r map[string]interface{}) (interface{}, error) {
fmt.Println("function3 started", r["f1"])
return nil, nil
}
f4 := func(r map[string]interface{}) (interface{}, error) {
fmt.Println("function4 started", r)
return nil, nil
}
res, err := goflow.New().
Add("f1", nil, f1).
Add("f2", []string{"f1"}, f2).
Add("f3", []string{"f1"}, f3).
Add("f4", []string{"f2", "f3"}, f4).
Do()
fmt.Println(res, err)
}
Output will be:
function1 started
function3 started 1
function2 started 1
function4 started map[f2:some results f3:<nil>]
map[f1:1 f2:some results f3:<nil> f4:<nil>] <nil>
