How to update panel assets

The following commands will install the necessary dependencies for building the Panel assets.

The build tools require NodeJS, yarn is used as the package manager.

sudo apt install -y nodejs

# CentOS
curl -sL https://rpm.nodesource.com/setup_22.x | sudo -E bash -
sudo yum install -y nodejs yarn # CentOS 7
sudo dnf install -y nodejs yarn # CentOS 8, Rocky Linux 8, AlmaLinux 8

Install required javascript packages.

npm i -g yarn # Install Yarn

cd /var/www/pterodactyl
yarn # Installs panel build dependencies

The following command will rebuild the Panel frontend. For NodeJS version 17 and above, you must enable the --openssl-legacy-provider option before building.

cd /var/www/pterodactyl
export NODE_OPTIONS=--openssl-legacy-provider # for NodeJS v17+
yarn build:production # Build panel

You can use command yarn run watch to view the progress of your changes in almost real-time for easier development. Once you're satisfied with your changes build the panel using the previously mentioned yarn build:production command.
