We’re happy to announce that the latest
npm package for error tracking of your front-end with AppSignal has just been released. 🚀
For those of you who aren’t really familiar with our error tracking service, we suggest you to take a deeper look into our docs.
This was one of the bigger releases, and it includes many improvements and bug fixes. Here’s what we’ve done:
Passing an Undefined Key in Development Logs Errors To the Console
While you’re working on your app locally, you can now add AppSignal to your front-end app without sending calls to AppSignal. This makes it useful for development since you don’t have to check AppSignal while debugging errors, but you can rely on the console itself.
All you need to do is to pass an
undefined key to the constructor, which will switch into development mode, and the client will output the span to the console and rethrow the error.
Added Support for Running Inside Node.js and Using Only the Error Tracking Part of AppSignal
We’ve added support for Node.js and removed the implicit dependency of the
This means that the integration works in any JS environment regardless of the availability of the DOM or the
window object. This enables those writing serverless functions for things like AWS Lambda to use an unpolished form of the error tracking portion of our service. Right now, the app will assume that the errors come from your front-end, so it will add geolocation for the IP address that sends the error, and it will put everything in the ‘front-end’ namespace. Let us know if you want to use this setup, and when enough people do, we will bump up the polishing in our planning.
Ignoring URLs With Option in
The 1.1.0 of @appsignal/plugin-breadcrumbs-network has the ability to ignore URLs with an option array of regexps.
If any of the URLs passed as ignoreUrls match the URL of the current request, no breadcrumb is added for it.
This comes in handy when you’re trying to omit requests going outside your own domain, from e.g. analytics scripts since these provide no value for you and just clutter the saved error report.
As a regular housekeeping task, we always update all of our dependencies, so that you don’t face any potential issues while monitoring your app with AppSignal.
