Sveltekit - PHP

Introduction

Since today i used adapter static for PHP sites (due to hosting only providing that option). And manually editing the prerendered HTML file or adding my custom API Endpoints.
This project aims to blend Sveltekit and PHP and keep all that magic of svelte (preloads and ssr ^**).

Install

NPM

npm i --save-dev sveltekit-php

PNPM

pnpm add -D sveltekit-php

Setup

Adapter

In your svelte.config.js import the adapter

import adapter from "sveltekit-php";

Root Layout

In order to corrctly use the PHP-Adapter, you should put this code into your root +layout.server.js.

export const prerender = true;
export const ssr = true;
export const trailingSlash = "always";

• prerender: is necessary to create the HTML/PHP file
• ssr: is necessary to fetch data on request and for preloading data
• trailingSlash: is needed to generate a path/index.php file instead of a path.php file.

Usage

Step 1

Create a +page.server.php or +layout.server.php
Where you would normally use a +page.server.js or +layout.server.js, you can use a +page.server.php or a +layout.server.php file.

_{(Note: layout.server.php fetches all parent data and can not be resetted.)}

Step 2

Write your load function.

<?php
function load($param){
    $routeid = $param["routeid"];
    $parentdata = $param["parentdata"];

    return [
        "message" => "Hello by PHP Server"
    ];
}
?>

Missing features

Planed to be implemented

• Streaming data
• Form actions

Don't know how to fix yet

• First SSR render with correct data
• Live preview (Vite)

Not planing to implement

• Reset layout

What about those ^** ? 😒

Preloads work fine, but since the pages are prerendered the default data (in +page.server.js if you choose to use it) can be seen for a split second.
The server generated data (by PHP) is already inlined into the document to be rendered as fast as possible.

Maybe you have the solution to this problem.
