Original GitHub issue: https://github.com/hoppscotch/hoppscotch/issues/1890

Big responses hangs the UI. It doesn't completely freeze but it turns out to be unusable.
This happens either as PWA or in the browser

Steps to reproduce the behavior:

Open the webapp
Make a request with a big JSON response, (my case it shows 200kb but not sure this is accurate)
It hangs

Expected behavior
UI should warn that the payload is too big to display and not hang

Screenshots

Desktop:

OS: Windows 10
Browser Brave (with all ads/script blocking disabled)
Chromium 94

Do you have an estimate of the response size which resulted in hang.

Thanks for providing the details. We'll look into our supporting libraries and see if there's any issues with responses of this size. Anyway will introduce an apt prompt if it exceeds the limit.

We've updated the CodeMirror editor (the library which we use in Hoppscotch) to v6. This has bought several performances boost to the render engine and now handles responses with more than 200kb. Hence closing.
