I have a single page application that communicates with a few different APIs, and I am hoping to throttle requests made to a specific one for testing. Is it possible to be domain specific with network throttling using Chrome DevTools?
I know you can throttle the network in Chrome and simulate a slow connection (e.g. Regular 3G connection) via the Network conditions tab, but this affects all requests. I am hoping to just affect one specific API to simulate the situation where this other service is really slow but all others are fine.
No, Chrome DevTools network throttling does not allow you to do selective throttling.
If you want to simulate specific services being slow and you have them running on your local machine, I would recommend installing a throttling proxy (e.g. Charles proxy).
If those services are deployed and you still want to simulate sluggish response, I would try amending /etc/hosts to point to a local charles proxy as well.
