README

Exponential Platform DXP is an open-source Digital Experience Platform (DXP/CMS) built on Symfony 7.4 LTS with PHP 8.3+. This is the DXP v5 Starter Skeleton — the ready-to-deploy project template for Exponential Platform DXP v5.

This is a website skeleton for Exponential Platform DXP (Stable; Platform v5; Open Source). No LegacyBridge, no classic legacy kernel — just the clean, forward-only Symfony 7.4 LTS new stack running the full Exponential Platform v5 OSS DXP content engine.

Exponential Platform DXP Project Notice

"Please Note: This project is not associated with the original eZ Publish software or its original developer, eZ Systems."

This is an independent, 7x + community-driven continuation of the platform. The Exponential Platform DXP codebase is stewarded and evolved by 7x (se7enx.com) and the open-source community of developers and integrators who have relied on it for decades.

Exponential Platform DXP Project Status

Exponential Platform DXP has made it beyond its end of life in 2021 and survived. The Platform v5 (5.0.x) release line is the new-stack, forward-only release targeting Symfony 7.4 LTS and PHP 8.3+.

The platform is under active development and targeted improvement. The 5.0.x (Platform v5) release series is the current active development branch. This is the pure single-kernel release and the first major version series to run exclusively on Symfony 7.4 LTS with full PHP 8.3+ support. Ongoing work focuses on:

Symfony 7.4 LTS new-stack kernel development and stabilisation
PHP 8.3 and 8.5 full compatibility and testing
REST API v2, GraphQL, and JWT authentication on Symfony 7.4 LTS
Dependency upgrades across Composer and Yarn package ecosystems
Security patches and vulnerability triage
Documentation and developer experience improvements

Who is 7x

7x is the North American corporation driving the continued general use, support, development, hosting, and design of Exponential Platform DXP Enterprise Open Source Content Management System.

7x has been in business supporting Exponential Platform website customers and projects for over 24 years. 7x took over leadership of the project and its development, support, adoption and community growth in 2023.

What is Exponential Platform DXP?

The Platform v5 Single-Kernel Architecture

Exponential Platform DXP v5 runs a single, modern content kernel:

New Stack — Exponential Platform v5 OSS (Symfony 7.4 LTS) — the full Platform v5 content engine providing REST API v2, GraphQL, Symfony controllers, the Platform v5 Admin UI, and first-class Twig template rendering.

The Platform v5 architecture is straightforward: one Symfony application, one kernel, one web entry point. There is no legacy bridge, no secondary kernel, and no dual-admin complexity. Content is rendered through Symfony Twig templates with full access to the Platform v5 content API.

Recent Improvements to Exponential Platform DXP

Exponential Platform DXP v5 (5.0.x) releases run the Exponential Platform v5 OSS new-stack kernel on Symfony 7.4 LTS with PHP 8.3+ — delivering the modern DXP experience on a fully supported, long-term-stable runtime.

What Does Exponential Platform DXP Provide for End Users Building Websites?

Exponential Platform DXP is a professional PHP application framework with advanced CMS (content management system) functionality. As a CMS, its most notable feature is its fully customizable and extendable content model. It is also suitable as a platform for general PHP development, allowing you to develop professional Internet applications, fast.

Standard CMS functionality, like news publishing and content management, is built in and ready for you to use. Its stand-alone libraries can be used for cross-platform, secure, database independent PHP projects.

Exponential Platform DXP is database, platform and browser independent. Because it is browser based it can be used and updated from anywhere as long as you have access to the Internet.

Key CLI Commands Reference

A quick reference for the most frequently used Symfony, Platform v5, and Admin UI console commands.

Command Prefix Convention: Commands using the exponential: prefix are canonical in this distribution. The old ibexa:* name works as a deprecated alias for migrated commands. The ezplatform:* / ezpublish:* prefixes do not exist in Platform v5. Commands not yet migrated retain their ibexa:* name.

Symfony Core

php bin/console list                                          # list all registered commands
php bin/console help <command>                                # help for a specific command
php bin/console cache:clear                                   # clear application cache
php bin/console cache:clear --env=prod                        # clear production cache
php bin/console cache:warmup --env=prod                       # warm up prod cache after deploy
php bin/console cache:pool:clear cache.redis                  # clear a specific cache pool
php bin/console debug:router                                  # list all routes
php bin/console debug:container                               # list all service IDs
php bin/console debug:config <bundle>                         # dump resolved bundle config
php bin/console debug:event-dispatcher                        # list all event listeners
php bin/console assets:install --symlink --relative public    # publish bundle public/ assets
php bin/console messenger:consume                             # consume async message queue

Doctrine / Migrations

php bin/console doctrine:migration:migrate --allow-no-migration   # run pending migrations
php bin/console doctrine:migration:status                          # show migration status
php bin/console doctrine:migration:diff                            # generate a new migration
php bin/console doctrine:schema:validate                           # validate entity mappings

Exponential Platform v5 (new stack)

Command Prefix Convention: exponential:* is canonical. ibexa:* is a deprecated alias for migrated commands. The ezplatform:* prefix does not exist in Platform v5.

php bin/console exponential:install exponential-oss           # fresh install with demo data
php bin/console exponential:reindex                           # rebuild search index (full)
php bin/console exponential:reindex --iteration-count=50      # incremental reindex
php bin/console ibexa:cron:run                                # run the Platform v5 cron scheduler
php bin/console ibexa:graphql:generate-schema                 # regenerate GraphQL schema from content model
# Solr: no console command in v5 — provision cores via Solr Admin HTTP API
php bin/console bazinga:js-translation:dump public/assets --merge-domains   # JS i18n
php bin/console fos:httpcache:invalidate:path / --all         # purge HTTP cache paths
php bin/console lexik:jwt:generate-keypair                    # generate RSA keypair for REST API auth

Admin UI & Site access points

URL	Description
`/adminui/`	Platform v5 Admin UI (new stack, React)
`/`	Public site (Symfony/Twig controllers)
`/api/ezp/v2/`	REST API v2
`/graphql`	GraphQL endpoint

Frontend / Asset Build (Yarn / Webpack Encore)

Activate Node.js 20 LTS via nvm before running any Yarn commands:

source ~/.nvm/nvm.sh && nvm use 20    # activate Node.js 20 LTS (required)
corepack enable                        # activates Yarn 1.22.22 as declared in package.json

yarn install            # install / update Node dependencies
yarn dev                # build all assets with source maps — dev mode
yarn build              # build all assets minified for production
yarn watch              # watch mode — auto-rebuild site assets on change
yarn ibexa:dev          # build Platform v5 Admin UI assets — dev mode
yarn ibexa:watch        # watch mode — auto-rebuild Admin UI assets on change
yarn ibexa:build        # build Platform v5 Admin UI assets — production

All ibexa:* scripts build through webpack.config.js using --config-name ibexa, which applies the required @ibexa-admin-ui alias and configuration.

See INSTALL.md for the complete step-by-step guide with server configuration, Solr, Varnish, and production deployment.
