AppSignal for JavaScript
AppSignal has amazing support for catching errors from front-end JavaScript applications and sending them to AppSignal. An npm library for catching JavaScript errors is available for that.
NOTE: Uncaught exceptions are not captured by default. Read this
section to find out why.
You can enable this functionality by enabling the
plugin-window-events plugin.
Supported browsers
This package can be used in any ECMAScript 5 compatible browser. We aim for compatibility down to Internet Explorer 9 (roughly 0.22% of all browsers used today). All browsers older than this can only supported on a “best effort” basis, and full functionality cannot be guaranteed.
When developing, don’t forget to check browser support on Can I Use? and the ES6 Compatibility Table, and provide the appropriate polyfills or fallbacks. In a small percentage of browsers, a Promise polyfill may be required to use this library.
Other supported environments
@appsignal/javascript is more than just a front-end library! It's also designed to work in a variety of other JavaScript runtimes and use-cases where the @appsignal/nodejs library may not be a viable choice. @appsignal/javascript supports:
- ✅ Electron apps
- ✅ Short-lived processes
- ✅ Serverless functions
- ✅ Statically generated apps
- ✅ React Native/Expo apps
