📚 Description

Like #540, this PR adapts the vercel preset to automatically support ISG strategies based on the swr/static route rule.

For example, the following config would create prerender functions for the blog & articles routes. The blog routes would be generated only once and then persisted; the articles routes would be regenerated every 360 seconds.

exportdefaultdefineNitroConfig({routes: {'/blog/**': {static: true},'/articles/**': {swr: 360}}})

Here's a deployment using this preset: https://verc-danielroe.vercel.app/

Hello 👋

Will this support a way to refresh a static page manually? For example with a bypassToken?

[danielroe]

That is planned, but not part of this PR. (It's a straightforward enhancement, so it should be fairly quick to implement, and I already have a local proof-of-concept.)

[bokub]

That's awesome, thanks a lot Daniel for your reactivity 👍

[danielroe]

We should be good to merge now - @TooTallNate fixed the upstream bug and also spotted an issue with a regexp. Sample deployment running with Vercel ISG: https://verc-danielroe.vercel.app.

Hi Daniel, sorry to bother you again on this question, but is there a way to refresh a static page manually (on-demand ISR) for a Nuxt project deployed on Vercel ?

I couldn't find anything in the current Nuxt documentation 😕

Thanks again !

[danielroe]

This isn't yet implemented but will be 😊

[bokub]

OK, thanks ! Is there some public road map or an issue I could follow to be alerted when this is implemented ?
