Feature

• ✅ Multiple namespace support
• ✅ Fail tolerant
• ✅ Custom logger
• ❎ YML to struct

Required

go 1.10 or later

Build

If you want build this project,should use go 1.11+

GO111MODULE=on; go mod download

Usage

Installation

# go mod (only go 1.11+) or project in gopath(go 1.10 +)
go get -u gopkg.in/apollo.v0
# if you use dep as your golang dep tool (go 1.10)
dep ensure -add  gopkg.in/apollo.v0

Set custom logger(Optional)

go-apoll use gopkg.in/logger.v1 as default logger provider. Any logger implemented apollo.Logger interface can be use as apollo logger provider(such as logrus).

//Logger interface
type Logger interface {
	Warnf(format string, v ...interface{})
	Warn(v ...interface{})
	Errorf(format string, v ...interface{})
	Error(v ...interface{})
	Infof(format string, v ...interface{})
	Info(v ...interface{})
	Debugf(format string, v ...interface{})
	Debug(v ...interface{})
	Fatal(args ...interface{})
	Fatalf(format string, args ...interface{})
}

set logrus as log provider

var log = logrus.New()
log.Formatter = new(logrus.JSONFormatter)
log.Formatter = new(logrus.TextFormatter)                     //default
log.Formatter.(*logrus.TextFormatter).DisableColors = true    // remove colors
log.Formatter.(*logrus.TextFormatter).DisableTimestamp = true // remove timestamp from test output
log.Level = logrus.TraceLevel
log.Out = os.Stdout

apollo.SetLogger(log)

Start use default app.yml config file

    apollo.Start()

Start use given config file path

    apollo.StartWithConfFile(name)

Subscribe to updates

    events := apollo.WatchUpdate()
    changeEvent := <-events
    bytes, _ := json.Marshal(changeEvent)
    fmt.Println("event:", string(bytes))

Get apollo values

    apollo.GetStringValue(Key, defaultValue)
    apollo.GetStringValueWithNameSapce(namespace, key, defaultValue)
    apollo.GetIntValue(Key, defaultValue)
    apollo.GetIntValueWithNameSapce(namespace, key, defaultValue)

Get namespace file contents

    apollo.GetNameSpaceContent(namespace, defaultValue)
