svelte-preprocess VS SvelteKit

You can learn more about the official svelte-preprocess and other available config here

svelte-preprocess is responsible for processing things like TypeScript and SCSS. The svelte compiler itself is only responsible for turning the svelte file into JavaScript.

svelte-preprocess should handle scss out-of-the-box, and it’s included in SvelteKit by default if you created your project with create-svelte

// svelte.config.js import sveltePreprocess from 'svelte-preprocess' export default { // Consult https://github.com/sveltejs/svelte-preprocess // for more information about preprocessors // **here -> postcss: true** preprocess: sveltePreprocess({ postcss: true, }) }

/** @type {import('@sveltejs/kit').Config} */ const config = { // Consult https://github.com/sveltejs/svelte-preprocess // for more information about preprocessors preprocess: preprocess({ typescript: true, postcss: true, scss: { prependData: @import 'src/styles/helpers/functions.scss'; } }), kit: { paths: { assets: '', base: dev ? '' : '/route/in/website' }, trailingSlash: 'always', adapter: adapter({ pages: 'build', assets: 'build', fallback: 'index.html' }), files: { hooks: 'src/hooks', }, prerender: { default: true, }, } };

In svelte.config.js ... (import aliases can be whatever you want)

1. import svelte_preprocess from 'svelte-preprocess'
2. import autoprefixer from 'autoprefixer'
3. pass the Svelte preprocessor to Kit's preprocess config option and pass the postcss plugin to that Svelte preprocessor:

svelte.config.js

import svelte_proprocess from 'svelte-process'
import autoprefixer from 'autoprefixer'

const config = {
    // Consult https://github.com/sveltejs/svelte-preprocess for more info
    preprocess: [
        svelte_preprocess({
            postcss: {
                plugins: [autoprefixer()]
            }
        })
    ]
}

import adapter from '@sveltejs/adapter-auto'; import preprocess from 'svelte-preprocess'; import { mdsvex } from 'mdsvex'; import remarkMath from 'remark-math'; import rehypeKatex from 'rehype-katex-svelte'; /** @type {import('@sveltejs/kit').Config} */ const config = { extensions: ['.svelte', '.svx', '.md'], // Consult https://github.com/sveltejs/svelte-preprocess // for more information about preprocessors preprocess: [ preprocess(), mdsvex({ extensions: ['.svx', '.md'], smartypants: true, layout: { project: "./src/routes/projects/layout.svelte", post: "./src/routes/blog/layout.svelte", }, remarkPlugins: [remarkMath], rehypePlugins: [rehypeKatex], }), ], kit: { adapter: adapter({ edge: false, external: [], split: false }) } }; export default config;

Have you tried https://github.com/sveltejs/svelte-preprocess

// We have changed the adapter line to use adapter-node@next import adapter from '@sveltejs/adapter-node@next'; import preprocess from 'svelte-preprocess'; /** @type {import('@sveltejs/kit').Config} */ const config = { // Consult https://github.com/sveltejs/svelte-preprocess // for more information about preprocessors preprocess: preprocess(), kit: { // We have changed this to point to a build directory adapter: adapter({ out: 'build' }) } }; export default config;

Svelte Kit for the fullstack framework It has first class support for Cloudflare Pages Svelte is a very elegant framework, and Svelte Kit is a very good meta-framework for Svelte. Svelte was probably the reason that…

This AI-powered Story Card Maker is built as a SvelteKit application with Typescript. Using Flowbite Svelte component library, the whole application was laid out. The layout for the Story Card (emulating the size of a postcard - 4" x 3") is created as an HTML Canvas using Fabric.js.

These adapters, for example, were built by the community: https://github.com/sveltejs/kit/tree/master/packages/adapter-vercel https://github.com/nuxt/vercel-builder If somebody builds a working one for Angular Universal, we will gladly add it to our Framework Presets → https://vercel.com/docs/concepts/deployments/build-step#framework-preset.

UPDATE: If you liked this project and are curious to see what it might look like as a SvelteKit app, check out this blog post by Tim Smith where he converts this existing app over.

I've played around with several platforms in the last year or so. I've landed on the following setup that works very well for me and ticks all your boxes:

A SvelteKit[0] app hosted on Cloudflare pages. The repo is hosted on GitHub and hooked up to the Cloudflare Pages app [1]. On PRs, I get preview environments. On merge, the changes get deployed to my "production" website. I write blog posts and other content in markdown, which is then processed by mdsvex[2] with very minimal setup.

Mostly, my requirements were more focused around getting the actual framework, hosting, etc. out of my way so that I could focus on writing. Gatsby and Next.js were too configuration heavy and turned me off once I scratched beyond the surface.

Behind the scenes is a simple Sveltekit-powered server function to fetch a Spotify client token then find a user's recommendation playlist and its track information. A Deno edge function to performs this data fetch and renders server-side Svelte.

It’s 2024, and you are about to start a new project. Do you reach for React, a framework you know and love or do you look at one of the other hot new frameworks like Astro, Enhance, 11ty, SvelteKit or gasp, plain vanilla Web Components?

From part 0 to part 4, we built out CryptoFlow's backend service. Though we can quickly use Postman, VS Code's ThunderClient or automated tests to see the endpoints working easily, this isn't all we want. We want to actively interact with the backend service via some intuitive user interface. Also, a layman wouldn't be able to "consume" the service we've built in the last parts. This article introduces building out the user interface of the system. We will be using SvelteKit, a framework that streamlines web development, and TailwindCSS, the utility-first CSS framework. Let's dig in!
