This is an initial commit of a @bugsnag/js plugin for Azure Functions. It wraps the Azure Functions handler and catches unhandled exceptions. It also automatically adds the Azure Functions context to any errors reported to Bugsnag. This plugin is based on the AWS Lambda plugin. Basic unit tests are included.

Hi @dpolivy, thanks for the PR! We'll look to get this reviewed as soon as priorities allow. |
If two function invocations overlap, it is possible the context sent on an error contains incorrect data. Imagine this sequence:
1. Func 1 starts
2. Func 2 starts
3. Func 1 throws an error
In this scenario, since we're using a per-process client, the context reported with the error is a combination of function 1 and function 2 context.
To address this, we treat the scenario similar to the express plugin, and clone the client for each invocation so the metadata associated with it is correct.
This also adds a bugsnag property to the context, which the function can use to notify of errors (and have context included automatically).

Goal
This is an initial commit of a @bugsnag/js plugin for Azure Functions. It wraps the Azure Functions handler and catches unhandled exceptions. It also automatically adds the Azure Functions context to any errors reported to Bugsnag.
Design
This plugin is based on the AWS Lambda plugin. It exports a function to create a wrapper function which can be used around the individual Azure Functions handler.
I'm not very familiar with this codebase so I took my best guess on appropriate changes to integrate it based on the AWS Lambda plugin. Hopefully it provides a good starting point to getting this incorporated!
Changeset
A new plugin was added for Azure Functions
Testing
Basic unit tests are included, based on the AWS Lambda unit tests. I don't have the proper environment to be able to do much more e2e testing.
