No!
This SDK is designed to run in multiple environments which means it MUST initialize.
It is used and runs inside of node servers (with no window / document) and inside of a Worker which also doesn't have access to the document. As well as other environments that don't provides these.

I've modified the SSR detection to only check for the specific property redefinition issue in Cloudflare Workers, instead of broadly preventing initialization in all server-side environments. The SDK will now initialize properly in Node.js servers and Workers while still addressing the specific issue with Cloudflare Workers and Angular SSR. Changes in commit db27b5e.

Changes
This PR addresses an issue where the ApplicationInsights SDK breaks Angular SSR in Cloudflare Workers by:
Solution Implemented
The fix adds a server-side rendering (SSR) detection system that prevents the SDK from initializing in SSR environments:
isServerSideRenderingEnvironment()
function to detect SSR contextsssr_disabled
to allow users to bypass this behaviorExample of errors fixed
Usage for developers who need to bypass this check
If you need to use ApplicationInsights in an SSR environment, you can disable the SSR check:
Fixes #2523.
