Today we’re really excited to announce Firepad,\ a Firebase-powered open source collaborative text editor.
Firepad provides true collaborative editing, complete with intelligent\ OT-based merging and conflict resolution.\ It’s full-featured and has support for both rich text and code editing. Some of its features include cursor\ position synchronization, undo / redo, text highlighting, user attribution, presence detection,\ and version checkpointing.
Since it’s powered by Firebase, Firepad provides all of the features you would normally\ expect from a Firebase app: low latency updates, offline mode support, first-class security controls,\ automatic scaling, and easy data accessibility. Firepad stores the full revision history of your document\ in a Firebase database, so it’s easy to integrate Firepad documents into larger apps. Your data is available in all of\ the normal ways: through client libraries, the REST API, and your App Dashboard.
We Heard You Loud and Clear
After our launch last year we saw a slew of activity around Firebase and real-time text editing.\ It quickly became apparent that this was the primary use-case for many of our developers. After\ seeing at least a dozen separate implementations, we thought it was time to lend a hand.
Building a correctly-implemented, full-featured collaborative text editor is a difficult task,\ even with the help of Firebase. Since our team already had some expertise in this area\ (It helped that I previously led the editor team for Visual Studio at Microsoft), we decided that\ the best approach would be to build our own complete version as an open source project.\ This way our developers could start their projects from a solid foundation without needing to\ take the time to build their own.
What’s the Big Deal?
High-quality collaborative document editing has so far been the domain of only a select few\ (generally large) companies. With Firepad, we aim to change that. Our goal is to enable any\ developer to build a high quality collaborative experience, whether her company is as big\ as Google or not.
Credit Where Credit is Due
Firepad was not built from scratch. We depend on the CodeMirror editor to actually render the\ document. We chose CodeMirror as we believe it has the best API of any open source editor.
We also borrowed from the code and concepts of\ ot.js. Thank you Tim Baumann!
Our launch of Firepad today is just the beginning. We will continue to actively develop\ Firepad to ensure it remains the best way to add real-time collaboration to your text editing app.
We hope the community will help us on this mission. Firepad is\ on Github, and all of the code\ is MIT-licensed, so feel free to fork and play to your heart’s content. We’ve even included\ a test suite to help you catch any bugs. And, if you build something great,\ please send us a pull request!
One area where we expect to see significant interest is in extending our support for rich\ text. Our rich text operational transform code is designed to be easily extended, so if\ you want to add additional formatting options, just jump in and give it a try. We’ll soon\ be adding new features here as well, including bulleted lists, text alignment options, and more.
We look forward to seeing what you build! As always, we love feedback, so please\ get in touch with your thoughts, comments, and suggestions.
