Astro redirects should not generate HTML stubs when using an adapter

[mashehu]

Are you using an SSR adapter? If so, which one?

Netlify

What package manager are you using?

What operating system are you using?

MacOS

What browser are you using?

Chrome, Firefox

Describe the Bug

When using configured redirects on netlify I see the placeholder HTML with "Redirecting to: " for a moment, before the browser is redirected to the correct site.

What's the expected result?

Based on the wording in the documentation:

When running astro build, Astro will output HTML files with the meta refresh tag by default. Supported adapters will instead write out the host’s configuration file with the redirects.

I assumed that the netlify adapter, would only write to the _redirects file, without generating these placeholder files, which give a quick flash of an unstyled page between pages.

See my minimal example deployment: https://main--thriving-dusk-04bc5b.netlify.app/

I just dropped by to create the same issue. This began appearing after a recent update of the adapter and was not present prior to that.

Ah yep, this behavior became more noticable when #7644 was merged, but I suspect this has never worked properly in hybrid mode.

We should be bypassing these files in hybrid mode as well and only generate the _redirects file so Netlify can handle it.

This is also relevant for the Vercel and Node adapters in hybrid mode

Before creating a new issue:

I am trying to implement redirects but its not working in prod (in dev all good):

redirects: {
  '/my-account/my-bookings/[hash]': '/nl/my-account/bookings/[hash]',
  '/my-account/my-profile': '/nl/my-account/profile',
  '/en/my-account/my-bookings/[hash]': '/my-account/bookings/[hash]',
  '/en/my-account/my-profile': '/my-account/profile',
  },

Everything gets redirected to /. Maybe this feature is for static builds? I'm using node adapter (I also see the placeholder).

Is this related to this issue? Thanks

You can disable the stubs with build.redirects = false while still getting the _redirects config update. I think I agree that Netlify should be setting this for you. I'll look into it.

[jdozierezell]

@matthewp it looks like skipping the stubs now results in redirects being case sensitive (as is typical with redirects set directly in Netlify). Is there a workaround for this or a way to reactivate the stubs via config setting? Skipping stubs is great, but now I'm dealing with a bunch of broken links.

I'm still seeing the "Redirecting to..." placeholders in Vercel. astro v 2.9.6, @astrojs/vercel v 3.7.4.

When I set build.redirects = false, the redirects stop working. Vercel and SSG.

This seems to happen on the latest Astro version. I'm using a Node adaptor and I still see the stub.
