Another thing you can do is

import { redirect } from "@sveltejs/kit";
throw redirect(303, '/');
Enter fullscreen mode Exit fullscreen mode

You're correct, they added support for this sometime after this article but I'll make sure to update it, thanks!

So I'm currently looking to move from my old blog, which has a filing structure like:

content/posts/2021/06/some-post-title/index.mdx
Enter fullscreen mode Exit fullscreen mode

In my blog currently that will be mydomain.com/2021/06/some-post-title

I'm looking to move to SvelteKit and use MDSveX and with Vite and the routing doesn't allow that (which I have found, and I've looked, like, a lot) so I'm looking to simplify the routes to something like:

src/routes/posts/some-post-title.svx
Enter fullscreen mode Exit fullscreen mode

How would I structure the redirects so that I'm not creating a path for each of the existing routes (130 odd)?

Do you have an example or some source code I could check out?

Thanks

You've added MDSvex with this adder? github.com/svelte-add/mdsvex

And you can't create a file like this src/routes/posts/2021/06/some-post-title/index.svx and then navigate to /posts/2021/06/some-post-title?

Thanks to @askrodney who helped me work this out...

For anyone else that has the same specific issue as me, make a file structure that mirrors the old filing structure, this is in the src/routes folder:

file structure

Then in the index file:

<!-- 
  Redirects from my old blog filing structure yyyy/mm/dd/post-title
  to posts/post-title thanks to rodneylab for the example 👇
  https://github.com/rodneylab/sveltekit-blog-mdx/blob/dev__redirect/src/routes/%5Byear%5D/%5Bmonth%5D/%5Bday%5D/%5Bslug%5D/index.svelte
 -->
<script context="module">
  export async function load({ page }) {
    const { slug } = page.params
    return {
      status: 301,
      redirect: `/posts/${slug}`,
    }
  }
</script>
Enter fullscreen mode Exit fullscreen mode

This worked perfectly for signing out a logged in user and redirecting them back to the homepage. Just needed to grab the request object from get and do some cookie magic. Thanks for the pattern!

Is this caused by a bug in sveltekit or?
I mean, should i not work without the header?

What do you mean a bug? Redirect headers are standard HTTP, routes (e.g. Svelte route files) do this for you if you pass a redirect property in your load response

What about doing this for going back to a previous page (history.back()) when a button is clicked..

This article was about doing server-side redirects.

For a client redirect, you could use history.back() or perhaps have a look at the navigation functions: kit.svelte.dev/docs#modules-$app-n...
