Getting Started With Firebase
Firepad requires Firebase in order to sync and store data. Firebase is a suite of integrated products designed to help you develop your app, grow your user base, and earn money. You can sign up here for a free account.
Live Demo
Visit firepad.io to see a live demo of Firepad in rich text mode, or the examples page to see it setup for collaborative code editing.
Downloading Firepad
Firepad uses Firebase as a backend, so it requires no server-side code. It can be added to any web app by including a few JavaScript files:
<head>
<!-- Firebase -->
<script src="https://www.gstatic.com/firebasejs/5.5.4/firebase.js"></script>
<!-- CodeMirror -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/codemirror/5.17.0/codemirror.js"></script>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/codemirror/5.17.0/codemirror.css"/>
<!-- Firepad -->
<link rel="stylesheet" href="https://cdn.firebase.com/libs/firepad/1.5.3/firepad.css" />
<script src="https://cdn.firebase.com/libs/firepad/1.5.3/firepad.min.js"></script>
</head>
Then, you need to initialize the Firebase SDK and Firepad:
<body onload="init()">
<div id="firepad"></div>
<script>
function init() {
// Initialize the Firebase SDK.
firebase.initializeApp({
apiKey: '<API_KEY>',
databaseURL: 'https://<DATABASE_NAME>.firebaseio.com'
});
// Get Firebase Database reference.
var firepadRef = firebase.database().ref();
// Create CodeMirror (with lineWrapping on).
var codeMirror = CodeMirror(document.getElementById('firepad'), { lineWrapping: true });
// Create Firepad (with rich text toolbar and shortcuts enabled).
var firepad = Firepad.fromCodeMirror(firepadRef, codeMirror,
{ richTextShortcuts: true, richTextToolbar: true, defaultText: 'Hello, World!' });
}
</script>
</body>
