Thanks to all the contributors for their great work on this project. I was wondering how many more votes is it gonna need before it gets worked on?

Sveltekit support will be much appreciated 😄 !!

Tight integration with SvelteKit is not currently planned. However, you can still use Contentlayer with SvelteKit.

I've done this with other frameworks that aren't officially supported. It usually looks like this:

1. Use a tool like concurrently to run contentlayer dev and the dev server in parallel.
2. Run contentlayer build prior to running the framework's build command.

I could create a working demo of a Sveltekit - Contentlayer - MDX integration with simple and little code.

For those interested here is the git repositiory: sveltekit-contentlayer-example

I hope this supports the Contentlayer project and helps to enlarge the Svelte / Contentlayer community.

Can parse md, but SvelteKit doesn't have enough support for mdx

Quite an allegation. Maybe you can elaborate what support you are missing.

yes please

Given a repository that's prepared to import/render the contentlayer content, would a Vite plugin work? All it does is invoke contentlayer build and contentlayer dev during the Vite lifecycle.

// vite.config.js
// @ts-check

import * as core from '@contentlayer/core'
import { fs, errorToString } from '@contentlayer/utils'
import { E, OT, pipe, S, T } from '@contentlayer/utils/effect'
import { sveltekit } from '@sveltejs/kit/vite'
import { defineConfig } from 'vite'

export default defineConfig({
  plugins: [
    sveltekit(),
    contentlayer(),
  ],
})
