Share config with NodeJs

Submitted by meertensm - 3 years ago

A laravel command to expose the configuration keys you define to the commandline. Below a NodeJs function that calls the command and parses the response

// Create a new command in your laravel installation
<?php

namespace App\Console\Commands;

use Illuminate\Console\Command;

class NodeJs extends Command
{
    
    /**
     * Here you define all the config keys you want to share with NodeJs
     */
    protected $keys = [
        'pusher' => 'broadcasting.connections.pusher',
        'mysql' => 'database.connections.mysql'
    ];
    
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'NodeJs:config';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'Get laravel settings in NodeJs';

    
    public function __construct()
    {
        parent::__construct();
    }

    /**
     * Execute the console command.
     *
     * @return mixed
     */
    public function handle()
    {
        $config = [];
        foreach($this->keys as $key => $value){
            $config[$key] = config($value);    
        }
        $this->info(json_encode($config));
    }
}
?>

// In your NodeJs app add the following function:

    var laravelSettings = function(callback){
        require('child_process').exec('php artisan NodeJs:config', function(error, stdout, stderr) {
            if (error !== null) {
                console.log('exec error: ' + error);
                return false
            }
            callback(JSON.parse(stdout));
        });
    };

// And use it

    laravelSettings(function(settings){
        // Settings will be in object format
        console.log(settings);
    });
