svelte-preprocess-splintered

This gives you Svelte components, but with HTML/Svelte, CSS, and JS in separate files.

I like the idea of components that contain everything, but I like having the option not to do it that way. Also, I have found it hard to get Atom to do the right thing in all cases.

With this pre-processor, your regular Svelte files will work exactly the same. However, whenever there is a file of the same name but with extension .mjs, .js, or .css it will get prepended to your Svelte file wrapped in respectively <script context="module">, <script>, and <style>.

You should keep importing .svelte as per usual. This module really just pre-bundles JS and CSS into Svelte files.

Installation

Just the usual: npm install -D --save svelte-preprocess-splintered.

Usage

Importing svelte-preprocess-splintered returns a function, and calling that function will produce a preprocessor which you can pass to Svelte's preprocess option (which can accept this value or an array of such values). This works in Rollup, Sapper, svelte-loader… Here is an example rollup.config.js using splintered Svelte:

import svelte from 'rollup-plugin-svelte';
import splintered from 'svelte-preprocess-splintered'

export default {
  …,
  plugins: [
    svelte({
      preprocess: splintered(),
      …,
    }),
  ],
};
