How to Fix JavaScript Errors

My computer programming teacher had always told me that 10% of our time is spent developing 90% of our application, and the other 90% of our time finishing the last 10% of our project. Even with a good project plan and a concept that makes logical sense, most of our time will be consumed with fixing errors. Moreover, with JavaScript, our application can run without obvious errors preventing it from being run, so we have to employ several techniques to make sure everything is running smoothly.

Instana Adds JavaScript Stack Trace Translation to Website Monitoring

The majority of organizations will ship production JavaScript code both minified and bundled into a single source file in order to speed up page load time. When reading JavaScript stack traces in production this is problematic due to the original source code being obfuscated and results in the stack trace becoming unreadable and unusable.

How to Catch (and Fix) JavaScript TypeErrors

It's Friday afternoon and you decide to check on your web logs one last time before you go out for the weekend. Since you've deployed recently, you want to make sure everything is going smoothly. You open your tool and suddenly you find your screen flooded with TypeErrors. Does this sound familiar? JavaScript TypeError is one of the most common browser errors because it wraps a number of different situations, each of which needs to be handled separately.

JavaScript Errors: An Exceptional History - Part II

Hello again! Welcome to the finalé of a two-part series of posts on errors in JavaScript. Last time, we took a look into the history of errors in JavaScript — how JavaScript shipped without runtime exceptions, how error handling mechanisms were later added both to the fledgeling web browsers of the day and to the ECMAScript spec, and how they future efforts to standardise these features would be connected to the politics of the browser wars of the late 90’s and 2000’s.

Deprecating Our Legacy JavaScript SDK

Sentry is full of engineers, so we know how painful it can be to deal with breaking changes caused by third party libraries. But we also know those third party libraries have to continually update and stay on top of their games, or they’ll become irrelevant. For that reason, we try to only introduce breaking changes when they’re really (really) required. Especially when those changes are made to an API surface.

JavaScript Errors: An Exceptional History

Hello again! It’s a historic week here at AppSignal! This week we released the first version of our new and improved JavaScript error monitoring. Now you can have your front end code, Ruby or Elixir back end code, your hosts, performance, everything monitored in one interface. To celebrate the launch, in a two-part series of posts, we’ll be taking a look at the history of Errors in JavaScript, including how to handle them in your code today.
