README

Install some files to run Laravel on Vercel.

Requirements

• PHP >= 8.2
• Laravel >= 10.0

Installation

composer require revolution/laravel-vercel-installer --dev

php artisan vercel:install

Uninstall

composer remove revolution/laravel-vercel-installer --dev

vercel.json

It will probably not work with the new spec that uses functions and rewrites in vercel.json.

regions

https://vercel.com/docs/edge-network/regions

builds

vercel-php@0.7.2 is PHP8.3

To use another version, check this repository. https://github.com/vercel-community/php

routes

If there are other files in public, add them to routes.

    {
        "src": "/images/(.*)",
        "dest": "/public/images/$1"
    },

env

Secret env is set in the vercel settings page.

php artisan key:generate --show command generates a new key without updating the .env file. Set this key on the Settings page APP_KEY.

Database

You can use Vercel Postgres or AWS RDS.

https://vercel.com/docs/storage/vercel-postgres

Cache and session

You can't use the file driver.

If you're using a database, you can use the database driver.

TrustProxies

Laravel 10

If you have any problems with TrustProxies, change /app/Http/Middleware/TrustProxies.php.

class TrustProxies extends Middleware
{
    /**
     * The trusted proxies for this application.
     *
     * @var array<int, string>|string|null
     */
    protected $proxies = '*';

Laravel 11

Change /bootstrap/app.php

->withMiddleware(function (Middleware $middleware) {
        $middleware->trustProxies(at: '*');
    })

API prefix

If you use Laravel's API routes, you will need to change the /api/ route as it conflicts with Vercel.

Laravel 11

/bootstrap/app.php

use Illuminate\Foundation\Application;

return Application::configure(basePath: dirname(__DIR__))
    ->withRouting(
        web: __DIR__.'/../routes/web.php',
        commands: __DIR__.'/../routes/console.php',
        api: __DIR__.'/../routes/api.php',
        apiPrefix: 'prefix/api',
        health: '/up',
    )

Disable build cache

Deployment often fails when you increase the package version in composer.json. To solve this, add VERCEL_FORCE_NO_BUILD_CACHE to Vercel's project settings - Environment Variables.　Setting it in vercel.json probably won't solve the problem.

• VERCEL_FORCE_NO_BUILD_CACHE : 1
