Overview

This library aims to facilitate passing values to JavaScript frameworks like Vue without the need to create an API. It is particularly useful for rapidly developing Web applications in a Multi-Page Application (MPA).

This project provides a middleware that allows passing PHP variables to JavaScript. It is designed to be used with frameworks that have a PSR-15 middleware stack.

Requirements

• PHP 8.2 or above
• Framework with PSR-15 compliant middleware stack

Installation

composer require nojimage/phpvjs

Add it to your PSR-15 middleware stack. Here's an example for CakePHP 5.x:

// src/Application.php
public function middleware(MiddlewareQueue $middlewareQueue): MiddlewareQueue
{
    // ...
    $middlewareQueue->add(new \Nojimage\PHPvJS\PHPvJSMiddleware());
    // ...
}

Usage

You can pass PHP variables to JavaScript using an instance of \Nojimage\PHPvJS\VariableCarry, which can be obtained from the request object attribute.

/*
 * @var \Psr\Http\Message\ServerRequestInterface $request 
 */

/** @var \Nojimage\PHPvJS\VariableCarry $carry */
$carry = $request->getAttribute(\Nojimage\PHPvJS\VariableCarry::class);
$carry->toJs('foo', $somevalue);

On the JavaScript side, you can access the PHP variables through the window.__phpvjs__ object.

console.log(window.__phpvjs__);
// or
const phpvjs = window.__phpvjs__ ?? {};

Integration with Vue.js

In the entry point script file:

import { createApp } from 'vue';

const app = createApp({
    data() {
        // Pass PHP variables to Vue.js using PHPvJS
        return window.__phpvjs__ ?? {};
    },
    // ... other options
});

// ...other setups

app.mount("#app");
