JavaScript Client Demo – Exceptionless

Exceptionless JavaScript Client

We’re getting closer and closer to version 1.0 of our JavaScript client, and we wanted to give everyone a demo of installation, configuration, and usage.

If you’re using Node.js, make sure to check out last week’s blog post for Node specific examples. Otherwise, continue reading for Javascript examples.

As you read and begin playing with the Exceptionless JavaScript client, please make note of any feedback, bugs, etc, and submit a GitHub issue so we can fast track version 1.0 – we surely appreciate it!


JavaScript Client Available for Preview & Testing!

Exceptionless JavaScript Client

That’s right ladies and gentlemen, we’ve been working on a JavaScript client, and it’s ready to peak it’s head out into the wild.

We’re talking beta status here, but version 1.0 is on its way and we wanted to let you guys play with it as soon as possible to provide feedback and help us work out the bugs, etc, quicker.

It’s tough to contain our excitement about getting this out there, and we hope you’ll check it out!

Exceptionless JavaScript Client Overview

The client supports Node.js and JavaScript, and you can find up-to-date installation, configuration, and usage documentation over on the GitHub repo.

Just like the non-JavaScript client, unhandled exceptions will be automatically sent upon configuration, and you can send log messages, feature usage events, etc. All the normal Exceptionless functionality is available.


Testers, developers, contributors, and feedback wanted! We want to make the Exceptionless Javascript client awesome, but we need your help. Give us any feedback you might have via GitHub an in-app message, contact form submission, or comment right here on this blog post. We’re more than happy to answer any and all questions, or help you get up and running.

Exceptionless V2.0.1 Shipped!

This release focused on bug fixes since the 2.0 release and include the below notable changes.

Exceptionless Server

  • API Status page now also checks the status of Storage, Queues and Message Bus.
  • Added the ability to requeue events (E.X., archived or events that failed to process).
  • Added the ability to send out system and release notifications.
  • Made the event posting and processing async. This has huge performance gains under load.

Please take a look at the Exceptionless changelog for a full list of the changes.


  • Added a busy indicators to some buttons allowing you to see the state of an action (E.G., Marking a stack as fixed).
  • Added the ability to refresh the app if there is a critical website bug.
  • Fixed a bug where some stack traces couldn’t be displayed.
  • Made some minor changes that make it a bit easier to self host (more to come 2.1).

Exceptionless API Usage and Overview

Exceptionless APISo you’ve been using Exceptionless for a while, but you wish you had a different dashboard, or maybe you’d like to integrate event data into one of your apps. No problem, just use the API!

Through our adventures while building Exceptionless, we’ve kept open source, automation, and ease of use in mind. With that, we think our API, which utilizes Swagger and Swashbuckle to automatically generate, update, and display documentation (which means it works automatically on self-hosted environments), is a great resource for our users that want to get their hands dirty and use Exceptionless data to roll their own tools, dashboards, etc.

Lets take a closer look at the API, how to use it, and some quick examples of what can be done. (more…)
