I think that you should remove the else block (keep it's content), so when you remove the stale cache, it still runs that code

[lilnasy]

@Alynva which else do you mean? Could you make a comment in the diff?

[Alynva]

@lilnasy Sorry, I was on mobile. I've added the suggestions now

[dreyfus92]

Maybe these fixes might help @lilnasy

[dreyfus92]

Just wondering if having new lines in between is intentional to improve readibility. If not I leave this minor suggestion @lilnasy.

Heads up!
We've just migrated the docs site from Netlify to Vercel. With that, the Netlify app has been removed, and will no longer update deploy previews. Vercel should post a comment with the new deploy preview the next time this PR is updated.

@sarah11918 is attempting to deploy a commit to the Astro Team on Vercel.

A member of the Team first needs to authorize it.

Why was this closed?

[lilnasy]

@selrond It was just sitting in the backlog for too long. We may still revisit this.

Although, a well-edited version of this was published as a blog post on logsnag! You may want check that out.

This information should be included in the docs. Astro is particularly attractive for projects that would also happen to greatly benefit from this technique.

I would also add this to the official docs. It includes deployment details for different hosting services, which are very valuable. Also reading from the official docs conveys more trust than a blog post. I read through the posts on Logsnag. They were really insightful and very well written. But the code is more like a POC (a very good one), which could potentially be extended with real cache providers.

On-Demand Revalidation would really be a killer feature with astro.js. It's the only real missing piece for me. Especially if you want to serve live data from a CMS which has a API request limit, like Sanity.
