📢 IMPORTANT NOTICE

This adapter heavily modifies SvelteKit's internal workings and build process also it's still in alpha.

Because of the way this package achives it's goals and the maintainers of SvelteKit disagreeing with the idea of an open node framework (Reference). We need to do a fair amount of modifications to the internal workings of SvelteKit, especially to the build process in order to make this package work.

Therefore it's extremly likely that new releases of SvelteKit (especially major releases) will not directly work with it. We try to update the adapter ASAP when breaking changes arrive in SvelteKit. Still it's more than possible that this adapter isn't directly compatible with the newest SvelteKit version. Especially shortly after an SvelteKit update.

Also another important part is that this adapter package is currently in alpha. We are still continuously adding new features, improving existing ones, as well as introducing breaking changes. We try to keep the amount of breaking changes as low as possible but it's likely that even not major releases will still introduce some.

That said when you still want to test out the adapter we highly recommend you, for the time being, to pin your SvelteKit version as well as the version of this adapter package.

👋 Introduction

sveltekit-adapter-custom is a SvelteKit adapter based on the @sveltejs/adapter-node build because of a strong disagree with the maintainers of adapter-node (Refer to motivation). It's goal is to be a drop in replacement for users which want to customize the underlying server to their liking. In order to achive this it gives it's users access to a wide variety of custom options and custom hooks.

🎩 Acknowledgements

A big shoutout to @dmoebius which wrote a beautiful comment on injecting custom code into all three environments of SvelteKit's workflow (dev, preview and production).

And a big shoutout to @carlosV2 which released an awesome SvelteKit adapter to inject a ws websocket server into SvelteKit.

NOTICE: The documentation is currently not complete.

For more information refer to the original adapter-node Documentation. Which is mostly valid for this adapter too.

📦 Getting Started

Simply run npm i -D sveltekit-adapter-custom@alpha, change the adapter in your svelte.config.js:

// svelte.config.js
import adapter from 'sveltekit-adapter-custom';

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

export default config;

install the vite plugin to your vite.config.js

// vite.config.js
import { sveltekit } from '@sveltejs/kit/vite';
import svelteKitCustom from 'sveltekit-adapter-custom/plugin';
import { defineConfig } from 'vite';

export default defineConfig({
    // ...
    plugins: [sveltekit(), svelteKitCustom()],
});

and add the provided hooks to your hooks.server.js file:

// hooks.server.js
// ...
/** @type {import('sveltekit-adapter-custom').SetupHook} */
export const setup = async (httpServer) => {
    // run your custom setup
};

🚀 Deployment

You just need the output directory (build by default) and the production dependencies to run the application. Production dependencies can be installed with the command npm install --production inside your output directory. You can then start your app with:

$ node index.js # inside your output directory

Your development dependencies get automatically bundled when needed.
