@eslym/sveltekit-adapter-fastcgi

A package to serve sveltekit app with fastcgi (which might be a very stupid idea).

Supports simple hosting and cluster mode. Cluster mode will automatically spawn and kill workers based on configuration and server load.

Install

npm i -D @eslym/sveltekit-adapter-fastcgi

yarn add -D @eslym/sveltekit-adapter-fastcgi

Usage

// svelte.config.js
import adapter from '@eslym/sveltekit-adapter-fastcgi';

export default {
    kit: {
        adapter: adapter({
            mode: 'simple' // or 'cluster'
        })
        // ...
    }
};
