My goal: When the app keeps growing, editing won't be a big problem cuz of the app size
-
Issue: always the browser runs out of memory and make me loose the latest changes and also it makes the editing/building apps hard
-
Additional Info:
I've experienced this in 2 OS (Mac, Windows) -
Screenshots:
Same here, editing my (multi-page) is not possible without it crashing constantly. Please fix this ASAP

it's becoming a blocker now and really makes me work at least twice on something as this issue is happening multiple times in a day 
Happening for me too, making it impossible to do anything on Retool. Complete blocker.

Also tried various different browsers and config changes, plugin disabling. Same thing happens on all of them.

Can see I'm on a ViteJS variant - wonder if they've rolled out a new bundling/deploy method that is causing this?

Hi all - thanks for reporting this! We are investigating internally and will provide an update as soon as we know more.

Hi @CoderNadir and @kietay, I'm following up from Support with an update for you. Our engineering team has reverted an earlier change they believe to have been contributing or outright causing this performance degradation. Can you confirm that the performance issues have now subsided on your ends?

@CoderNadir Have you seen this when editing multiple apps or only one a single app? And can you share the page UUIDs of the app(s) where you've seeing this issue? The UUID is the long string of random characters in the page URL.
I was editing the same app but opening 2 pages in 2 different tabs
Sharing my App UUID in your DM!
I see, thanks for that context! Have you only observed this behavior when editing two pages of the same multi-page app in 2 different tabs?
And have you only seen this issue on that specific app?
@everett_smith yes I believe this happened for me only when I had 2 tabs having the app on editor mode
This issue is popping up many times today! (refreshed the app ofc to load latest versions before start working and whenever it asks me to)
Also the saving functionality isn't working properly sometimes, as it shows that some changes got saved but when I preview the app and want to check the changes I don't find them!
Hi @CoderNadir, I think the performance issues you're seeing while editing this specific app are largely stemming from the size of the app and it's pages. Looking at some performance related metadata for the app I see that the app itself and some of the pages are above Retool's Massive App size performance threshold (the app has 2950 components and queries and some of the pages have roughly 800 components and queries). At this size, it's typical to begin to see some slowdowns in the app, especially in the editor where there is additional overhead. Base on the above, you'll need to revisit the design for the pages of this app or potentially the app as a whole, splitting out functionality to cut down on the size (e.g. amount of components, queries, code) on each page. Additionally, I would suggest avoiding editing an app of this size in two tabs simultaneously, since that's dramatically increasing the resources your browser is consuming on your machine.

About editing into 2 pages, I open 2 pages just to copy existing code from one to another
thank you for the notes!
