Firebase adapter for Webix UI

Library allows using Webix components with FireBase

Latest version will work with Webix 6.2+, if you are using an older version of Webix, you need to use version 0.5 of this package.

Citing the Firebase site:

When data changes, apps built with Firebase update instantly across every device -- web or mobile.

Firebase-powered apps work offline. Data is synchronized instantly when your app regains connectivity.

Firestore

Include Webix and Firebase files on the page

<!-- Webix -->
<script type="text/javascript" src="http://cdn.webix.com/edge/webix.js"></script>
<link rel="stylesheet" type="text/css" href="http://cdn.webix.com/edge/webix.css">
<!-- Webix-Firebase adapter -->
<script type="text/javascript" src="../codebase/webix-firestore.js"></script>
<!-- FireBase -->
<script src="https://www.gstatic.com/firebasejs/5.0.4/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/5.0.4/firebase-firestore.js"></script>

Create main firebase connection

firebase.initializeApp({
	apiKey: "YOU API KEY HERE",
	projectId: "webix-demo"
});

// create firebase connection, and assign it to webix
var db = firebase.firestore();
db.settings({ timestampsInSnapshots:true });

webix.firestore = db;

Init webix component, using "firebase->{reference}" as data url

webix.ui({
	id:"dtable",
	view:"datatable",
	autoConfig:true,

	// load data from "books" collection
	url: "firestore->books",
	// save data to "books" collection
	save:"firestore->books"
}

That is it.

Adding "url" property will enable data loading and automatic updates of component when data changed in the firebase.

Adding "save" property ensures that all changes in the datatable will be saved to the Firebase

Using FireBase references

Instead of using text url you can use firestore collections directly

firebase.initializeApp({
	apiKey: "YOU API KEY HERE",
	projectId: "webix-demo"
});

// create firebase connection, and assign it to webix
var db = firebase.firestore();
db.settings({ timestampsInSnapshots:true });

var proxy = webix.proxy("firestore", db.collection("books"));

webix.ui({
	view:"list",
	url: proxy,
	save: proxy
}););

Dynamic data loading

You can use "load" command to (re)load data in the component.

$$("dtable").clearAll();
$$("dtable").load("firestore->books");

or

$$("dtable").clearAll();
$$("dtable").load( webix.proxy("firestore", collection) );

Realtime Database

Include Webix and Firebase files on the page

<!-- Webix -->
<script type="text/javascript" src="http://cdn.webix.com/edge/webix.js"></script>
<link rel="stylesheet" type="text/css" href="http://cdn.webix.com/edge/webix.css">
<!-- Webix-Firebase adapter -->
<script type="text/javascript" src="../codebase/webix-firebase.js"></script>
<!-- FireBase -->
<script src="https://www.gstatic.com/firebasejs/5.0.4/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/5.0.4/firebase-database.js"></script>

Create main firebase connection

firebase.initializeApp({
  databaseURL: "https://webix-demo.firebaseio.com/"
});

// create firebase connection, and assign it to webix
webix.firebase = firebase.database();

Init webix component, using "firebase->{reference}" as data url

webix.ui({
	id:"dtable",
	view:"datatable",
	editable:true, editaction:"dblclick",
	columns:[{
		id:"name", editor:"text", fillspace:1
	},{
		id:"author", editor:"text", fillspace:1
	}],

	// load data from /books
	url: "firebase->books",
	// save data to /books
	save:"firebase->books"
}

That is it.

Adding "url" property will enable data loading and automatic updates of component when data changed in the firebase.

Adding "save" property ensures that all changes in the datatable will be saved to the Firebase

Using FireBase references

Instead of using text url you can use firebase references directly

firebase.initializeApp({
	databaseURL: "https://webix-demo.firebaseio.com/"
});
var db = firebase.database();
var proxy = webix.proxy("firebase", db.ref("books"));

webix.ui({
	view:"list",
	url: proxy,
	save: proxy
});

Dynamic data loading

You can use "load" command to (re)load data in the component.

$$("dtable").clearAll();
$$("dtable").load("firebase->books");

or

$$("dtable").clearAll();
$$("dtable").load( webix.proxy("firebase", ref) );

Sync api

Webix components have native sync api to sync data between components. The same api can be used with firebase

firebase.initializeApp({
	databaseURL: "https://webix-demo.firebaseio.com/"
});
webix.firebase = firebase.database();
var ref = webix.firebase.ref("books");

$$("dtable").sync(ref);

Working with Forms and Templates

Similar to data views, you can use "load" and "save" API while working with Forms

//form
$$("form").load("books/4");
...
$$("form").save();

//template
$$("template").load("books/4")

In some cases, it has sense to not load data correctly but bind form ( template ) to some other view or data collection

var data = new webix.DataCollection({
	url:"firebase->books",
	save:"firebase->books"
})
form.bind(data);
data.waitData.then(function(){
	//you need to use setCursor API to load some record from collection into a form
	data.setCursor("4");
})

or, the same for the datatable

webix.ui({
	view:"datatable", autoConfig:true, id:"d1", select:true,
	url:"firebase->books",
	save:"firebase->books"
});
form.bind("d1"); //selected row will be shown in a form
