@fjst/sveltekit

Wraps any SvelteKit adapter and runs your own transpilers over the built client .js files before the adapter finishes adapting.

Install

npm install @fjst/sveltekit
bun add @fjst/sveltekit

Usage

// svelte.config.js
import { jsObf } from "@fjst/core";
import sveltekitFjst from "@fjst/sveltekit";
import adapter from "@sveltejs/adapter-node";

/** @type {import('@sveltejs/kit').Config} */
const config = {
  kit: { adapter: sveltekitFjst(adapter(), [jsObf]) },
};

export default config;

sveltekitFjst takes the adapter you'd normally pass to kit.adapter, plus a list of transpilers, and returns a wrapped adapter. Every built client .js file is passed through each transpiler, in order, before being written to disk.

API

sveltekitFjst(adapter: Adapter, transpilers: Transpiler[]): Adapter

Transpiler

type Transpiler = (src: string, filepath: string) => string;

src is the file's contents and filepath is the absolute path it will be written to. The return value replaces the file's contents.

@fjst/core ships jsObf and jsMinify, both usable as-is.
