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/7.13.2/firebase-app.js"></script>
  <script src="https://www.gstatic.com/firebasejs/7.13.2/firebase-auth.js"></script>
  <script src="https://www.gstatic.com/firebasejs/7.13.2/firebase-database.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://firepad.io/releases/v1.5.10/firepad.css" />
  <script src="https://firepad.io/releases/v1.5.10/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>
