    Angular Websocket

    Angular Websocket

    The missing Angular WebSocket module for connecting client apps

    Angular Websocket is a WebSocket service tailored for AngularJS 1.x applications, exposed primarily through the $websocket factory in the ngWebSocket module. It wraps the native WebSocket API in a way that plays nicely with Angular’s digest cycle, ensuring that UI updates are triggered when messages arrive. The library manages an internal send queue so that messages requested before the socket is open are safely sent once the connection is ready. It offers a set of convenience methods and callbacks, such as onMessage, onOpen, onClose, and onError, to keep WebSocket handling consistent with other Angular services. Developers can filter messages by string or regular expression and optionally disable automatic $digest calls when needed for performance. The project can be consumed via Bower, npm, CDN, or manual download, making it easy to introduce into legacy build setups. It aims to be the “missing WebSocket module” for AngularJS.
