Is there a way to determine the evaluation time of a script using the performance API?

[alshdavid]

I am working on a project where the compilation output produces hundreds of small dynamic bundles. The performance of these bundles is obtained by placing the following automatically at compile time:

performance.mark('bundle-name:eval-start') 

// ...
// code
// ...

performance.mark('bundle-name:eval-end')

Looking at performance.getEntries(), I can see the resource timings for scripts, however I cannot see the any data on runtime performance, only network information.

Does the performance API offer the ability to inspect any runtime performance metrics?

Would a PerformanceObserver help you? https://developer.mozilla.org/en-US/docs/Web/API/Performance_API/User_timing#observing_performance_measures
