+# Config for NextJS
+
+```{note}
+NextJS is not officially supported on the Hypernode Platform. So please use this at your own risk,.
+```
+
+Configuration to use as Hypernode Deploy deploy.php for a NextJS webserver application:
+
+```php
+<?php
+
+declare(strict_types=1);
+
+namespace Hypernode\DeployConfiguration;
+
+use function Deployer\run;
+use function Deployer\task;
+use function Deployer\test;
+use function Deployer\within;
+
+task('node:install', static function () {
+    run('npm ci');
+});
+
+task('node:build', static function () {
+    run('npm run build');
+});
+
+task('deploy:pm2:install', static function() {
+    if (!test('grep -q "/data/web/.local/bin" ~/.bashrc')) {
+        run('echo "export PATH=/data/web/.local/bin:$PATH" >> ~/.bashrc');
+        run('source ~/.bashrc');
+    }
+
+    run('npm install -g pm2 --prefix /data/web/.local');
+});
+
+task('deploy:pm2:restart', static function() {
+    within('{{release_path}}', function () {
+        run('pm2 startOrRestart ecosystem.config.js --env prod');
+    });
+});
+
+$configuration = new Configuration();
+
+$configuration->setPlatformConfigurations([
+    new PlatformConfiguration\NginxConfiguration('etc/nginx'),
+    new PlatformConfiguration\HypernodeSettingConfiguration('supervisor_enabled', 'False'),
+    new PlatformConfiguration\HypernodeSettingConfiguration('rabbitmq_enabled', 'False'),
+    new PlatformConfiguration\HypernodeSettingConfiguration('elasticsearch_enabled', 'False'),
+    new PlatformConfiguration\HypernodeSettingConfiguration('opensearch_enabled', 'False'),
+    new PlatformConfiguration\HypernodeSettingConfiguration('varnish_enabled', 'False'),
+    new PlatformConfiguration\HypernodeSettingConfiguration('nodejs_version', '20'),
+]);
+
+$configuration->addBuildTask('node:install');
+$configuration->addBuildTask('node:build');
+
+$configuration->addDeployTask('deploy:pm2:install');
+$configuration->addDeployTask('deploy:pm2:restart');
+
+$configuration->setSharedFiles([
+    '.env'
+]);
+
+$configuration->setDeployExclude([
+    './.git',
+    './deploy.php',
+    '.gitignore',
+    './etc'
+]);
+
+$productionStage = $configuration->addStage('production', 'my-next-application.nl');
+$productionStage->addServer('app.hypernode.io');
+
+$acceptanceStage = $configuration->addStage('acceptance', 'my-next-application.nl');
+$acceptanceStage->addBrancherServer('app')
+    ->setLabels(['stage=acceptance']);
+
+return $configuration;
+```
+
+This will:
+
+- Configure the Hypernode settings optimal for the least load of non-used applications and servers.
+- Install [PM2](https://pm2.keymetrics.io/) if not present on the server.
+- Sets up a vhost for application.
+- Sets up the nginx configuration to proxy to the NextJS server.
+
+You will still need to add the nginx configuration file, so create the `./etc/nginx/server.headless.conf` file:
+
+```nginx
+location / {
+    proxy_pass http://localhost:3000;
+    proxy_http_version 1.1;
+    proxy_set_header Upgrade $http_upgrade;
+    proxy_set_header Connection 'upgrade';
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_cache_bypass $http_upgrade;
+
+    # Optional: set maximum response time to 60 seconds
+    proxy_read_timeout 60s;
+    proxy_connect_timeout 60s;
+}
+
+# Optional: specific location for static assets if they are served by Next.js
+location /_next/ {
+    proxy_pass http://localhost:3000;
+    proxy_cache_bypass $http_upgrade;
+}
+```
+
+And to save configuration about pm2, add the `ecosystem.config.js` file:
+
+```js
+module.exports = {
+    apps: [
+      {
+        name: 'my-next-app',
+        exec_mode: 'cluster',
+        instances: 'max', // Or a number of instances
+        script: 'node_modules/next/dist/bin/next',
+        args: 'start'
+      }
+    ]
+  }
+```
