Description

Many cloud IDEs use CDNs with DDOS mitigations that break Vite. I convinced CSB to fix their Cloudflare config, but Replit and probably many others also share the same issue.

Suggested solution

It would be ideal if we could configure a way to limit requests per second to around ~50. Replit starts blocking requests at around 70 per second. CSB used to be much more problematic before they fixed it.

Alternative

HTTP/2 or bundling requests in a denounce queue might also help. Or reattempting failed fetches with gradual back off if they got a 429 response, which is what CSBs Cloudflare and Replit give when DDOS protection kicks in.

Additional context

No cloud sandbox is great, they all have problems... with performance, configuration, support, networking, secrets, pricing, mandatory third party subscriptions, etc.

Replit's non-injected service worker shenanigans mitigate the problem if you refresh enough. In CSB the problem was fatal. Although I can imagine situations where Replit's SW cache could be problematic.

Update:

Rollup is working on the ability to set minimum chunk size... that could drastically lower overhead during dev.
