PHP, Symfony and Node.js versions #

This page is for developers and system administrators who prepare a machine for a DXP project. All numbers come from the skeleton's installation guide (section 1, "Requirements") and the two composer.json files.

The table #

PHP extensions and settings #

The skeleton's composer.json requires ctype, iconv, gd, curl, json, xsl, xml, intl and mbstring. The guide adds pdo_mysql, pdo_pgsql or pdo_sqlite for your database, imagick as an alternative to gd, and opcache.

Node.js and Yarn #

Node.js and Yarn build the site assets and the administration interface. The guide is strict: use Node.js 20 LTS only ("Do not use Node.js 18 or 22 — only 20 LTS is tested and supported for this release") and Yarn 1.22, activated with corepack enable. The Nexus v5 starter uses Node.js 22; follow the guide of the project you install (DXP skeleton, Limits).

source ~/.nvm/nvm.sh
nvm install 20
nvm use 20
corepack enable

Production servers do not need Node.js if you build the assets elsewhere and deploy the result (Building assets).

Check a machine in two minutes #

php -v                                   # 8.3 or newer
php -m | grep -iE "ctype|iconv|gd|imagick|curl|json|xsl|xml|intl|mbstring|pdo|opcache|sqlite"
php -i | grep -E "memory_limit|date.timezone|max_execution_time"
composer --version                       # Composer version 2.x
node -v                                  # v20.x
yarn -v                                  # 1.22.x

For an existing project, Composer can tell you what blocks a version:

composer check-platform-reqs
composer why-not php 8.2
