Firego

Deprecated in favor of firebase/firebase-admin-go.

---

A Firebase client written in Go

Installation

go get -u gopkg.in/zabawaba99/firego.v1

Usage

Import firego

import "gopkg.in/zabawaba99/firego.v1"

Create a new firego reference

f := firego.New("https://my-firebase-app.firebaseIO.com", nil)

with existing http client

f := firego.New("https://my-firebase-app.firebaseIO.com", client)

Request Timeouts

By default, the Firebase reference will timeout after 30 seconds of trying to reach a Firebase server. You can configure this value by setting the global timeout duration

firego.TimeoutDuration = time.Minute

Authentication

You can authenticate with your service_account.json file by using the golang.org/x/oauth2 package (thanks @m00sey for the snippet)

d, err := ioutil.ReadFile("our_service_account.json")
if err != nil {
    return nil, err
}

conf, err := google.JWTConfigFromJSON(d, "https://www.googleapis.com/auth/userinfo.email",
    "https://www.googleapis.com/auth/firebase.database")
if err != nil {
    return nil, err
}

fb := firego.New("https://you.firebaseio.com", conf.Client(oauth2.NoContext))
// use the authenticated fb instance

Legacy Tokens

f.Auth("some-token-that-was-created-for-me")
f.Unauth()

Visit Fireauth if you'd like to generate your own auth tokens

Get Value

var v map[string]interface{}
if err := f.Value(&v); err != nil {
  log.Fatal(err)
}
fmt.Printf("%s\n", v)

Querying

Take a look at Firebase's query parameters for more information on what each function does.

var v map[string]interface{}
if err := f.StartAt("a").EndAt("c").LimitToFirst(8).OrderBy("field").Value(&v); err != nil {
	log.Fatal(err)
}
fmt.Printf("%s\n", v)

Set Value

v := map[string]string{"foo":"bar"}
if err := f.Set(v); err != nil {
  log.Fatal(err)
}

Push Value

v := "bar"
pushedFirego, err := f.Push(v)
if err != nil {
	log.Fatal(err)
}

var bar string
if err := pushedFirego.Value(&bar); err != nil {
	log.Fatal(err)
}

// prints "https://my-firebase-app.firebaseIO.com/-JgvLHXszP4xS0AUN-nI: bar"
fmt.Printf("%s: %s\n", pushedFirego, bar)

Update Child

v := map[string]string{"foo":"bar"}
if err := f.Update(v); err != nil {
  log.Fatal(err)
}

Remove Value

if err := f.Remove(); err != nil {
  log.Fatal(err)
}

Watch a Node

notifications := make(chan firego.Event)
if err := f.Watch(notifications); err != nil {
	log.Fatal(err)
}

defer f.StopWatching()
for event := range notifications {
	fmt.Printf("Event %#v\n", event)
}
fmt.Printf("Notifications have stopped")

Change reference

You can use a reference to save or read data from a specified reference

userID := "bar"
usersRef,err := f.Ref("users/"+userID)
if err != nil {
  log.Fatal(err)
}
v := map[string]string{"id":userID}
if err := usersRef.Set(v); err != nil {
  log.Fatal(err)
}

Check the GoDocs or Firebase Documentation for more details

Running Tests

In order to run the tests you need to go get -t ./... first to go-get the test dependencies.
