Introducing HumbleNet: a cross-platform networking library that works in the browser
Announcing the release of HumbleNet, a project initiated at Humble Bundle in 2015 to port peer-to-peer multiplayer games, originally to asm.js and now to WebAssembly. The current open source version of the library exposes a simple peer-to-peer API that allows for basic peer discovery and the ability to easily send data (via WebRTC) to other peers. Today, you can build a game that runs on Linux, macOS, and Windows, while using any web browser — and they can all communicate in real-time via WebRTC.

Record almost everything in the browser with MediaRecorder
The MediaRecorder API lets you record media streams, i.e. moving images and audio. The result of these recordings can be, for example, an OGG file, like the ones you use to listen to music. Browser-wise, we can obtain streams in many ways. Let’s start with something you might be familiar with: we’ll get a stream […]

WebRTC: Sending DTMF in Firefox
One of the features defined in WebRTC is the ability to send DTMF tones (popularly known in some markets as “touch tones”). While this has basically no purpose in the browser-to-browser case, it is somewhat important when using WebRTC to initiate calls to the legacy telephone network: many companies still use voice menu systems that […]

Controlling WebRTC PeerConnections with an extension
Author’s note: Firefox recently added some features (in Firefox 42) to allow users to exercise added control over WebRTC RTCPeerConnections, IP address gathering used in connecting them, and what IP addresses are exposed to JS applications. For a detailed explanation of the issues this is addressing and why Firefox is addressing them, please see my […]

Peering Through the WebRTC Fog with SocketPeer
WebRTC allows browsers to do things they never could before, but a soup of unfamiliar terminology and the complexity of the API makes for a steep learning curve. After spending several weeks neck-deep in example code and cargo-culting several libraries, I have emerged with a workable understanding and a nifty library that helps hide some […]

WebRTC in Firefox 38: Multistream and renegotiation
Editor’s Note: A lot has changed since this post was published in 2013… WebRTC is now widely available in all major browsers, but its API looks a bit different. As part of the web standardization process, we’ve seen improvements such as finer-grained control of media (through tracks rather than streams). Check out this Simple RTCDataChannel […]

WebRTC requires Perfect Forward Secrecy (PFS) starting in Firefox 38
Today, we are announcing that Firefox 38 will take further measures to secure users’ communications by removing support in WebRTC for all DTLS cipher suites that do not support forward secrecy. For developers: if you have a WebRTC application or server that doesn’t support PFS ciphers, you will need to update your code. Forward secrecy, […]
