Transform stacktraces from javascript into readable stacktraces to improve OpenTelemetry usability.
When collecting stacktraces from javascript based application, the stacktraces are usually based on minified or compiled code.
Example:
padStart@http://localhost:4203/lineSlicer.min.js:1:228
padStart@http://localhost:4203/cubeSlicer.min.js:1:228
To be able to know where the actual problem is, you should combine this with a source map. Commercial tracing solutions provide ways to upload source maps to their dashboard, and they figure it out.
This processor is made so the generic OpenTelemetry collector can have the same functionality. Place the source maps in a directory and the processor will read them at startup. The end result:
padStart@lib/lineSlicer.js:11:53
padStart@http://localhost:4203/cubeSlicer.min.js:1:228
In this example the map for lineSlicer.js is available, but not for cubeSlicer. In that case the line is ignored, so there's always a full picture of the flow present.

This repository keeps a change log using GitHub's releases functionality. The format of the log is based on Keep a Changelog.
Releases are based on Semantic Versioning, and use the format
of MAJOR.MINOR.PATCH. In a nutshell, the version will be incremented
based on the following:
MAJOR: Incompatible or major changes.MINOR: Backwards-compatible new features and enhancements.PATCH: Backwards-compatible bugfixes and package updates.
This is an active open-source project. We are always open to people who want to use the code or contribute to it.
We've set up a separate document for our contribution guidelines.
