initialization
Is a package for initialization of the application modules. Ex. database connectors, service providers, etc.
Usage
package main
import (
"errors"
"log"
"time"
"git.ooo.ua/pub/armory/initialization"
"github.com/sirupsen/logrus"
)
func main() {
moduleList := initialization.Modules{
initialization.Module{
Name: "database_conn",
DependsOn: "",
Timeout: 15 * time.Second,
InitInterval: time.Second,
Init: func(entry *logrus.Entry) error {
entry.WithField("module", "database_conn").
Info("try to initialize module")
time.Sleep(500 * time.Millisecond)
return errors.New("ha-ha-ha")
},
},
initialization.Module{
Name: "rabbit",
DependsOn: "",
Timeout: 15 * time.Second,
InitInterval: time.Second,
Init: func(entry *logrus.Entry) error {
entry.WithField("module", "rabbit").
Info("try to initialize module")
time.Sleep(500 * time.Millisecond)
return nil
},
},
initialization.Module{
Name: "listener",
DependsOn: "database_conn",
Timeout: 15 * time.Second,
InitInterval: time.Second,
Init: func(entry *logrus.Entry) error {
entry.WithField("module", "listener").
Info("try to initialize module")
time.Sleep(500 * time.Millisecond)
return nil
},
},
}
err := moduleList.InitAll()
if err != nil {
log.Fatal("Init failed with error: ", err.Error())
}
}

type Module ¶
type Module struct {
// Name unique identifier for module.
Name string
// DependsOn is a name of other module which should be initialized before this.
DependsOn string
// InitInterval is initial timeout before second attempt to perform initCall.
InitInterval time.Duration
// Timeout is a deadline for the initialization attempts.
Timeout time.Duration
// Init is a module init function.
Init func(*logrus.Entry) error
}
Module is unit for initialization.
