H5P Bundle for Symfony

H5P Bundle is an open-source project designed to simplify the integration of H5P into Symfony applications.

The project is based on a port of the H5P Drupal module to Symfony and provides the components required to manage H5P library installation and updates, content import and export, content rendering, as well as selected usage data.

The bundle has been maintained over time to remain compatible with several major Symfony generations, including Symfony 4, 5, 6 and 7.

The project also provides permission management, H5P content handling, associated storage and the different mechanisms required to integrate H5P into a Symfony application.

Problem

H5P provides a complete ecosystem for creating and using interactive content, but its integration has historically been closely tied to platforms such as Drupal or WordPress.

The goal of H5P Bundle is to make it possible to use H5P directly within a Symfony application without relying on an external CMS.

This requires adapting the mechanisms required by H5P to Symfony's architecture and conventions.

How it works

The bundle provides the components required to integrate H5P into a Symfony application.

It notably supports:

• installation and updating of H5P libraries;
• import and export of H5P content;
• storage of content and associated files;
• rendering and integration of interactive content;
• permission management;
• tracking of selected usage data and scores.

The integration also relies on Doctrine for the persistence of data required by the bundle.

Symfony compatibility

A significant part of the project involves maintaining compatibility with different versions of the Symfony framework.

The bundle has been adapted over time to work with several major Symfony generations, including:

• Symfony 4
• Symfony 5
• Symfony 6
• Symfony 7

Maintaining this compatibility requires evolving the code according to changes in Symfony APIs, components and project dependencies.

Main features

• H5P integration within Symfony
• Installation and updating of H5P libraries
• H5P content import
• H5P content export and download
• Content and resource storage management
• Permission management
• Integration of interactive content into Symfony applications
• Storage of usage data and scores
• Compatibility with multiple major Symfony versions

Architecture and technical choices

The project is primarily developed in PHP and integrates directly with the Symfony ecosystem.

Doctrine is used to manage the persistent data required by the bundle.

A JavaScript layer is also required to integrate H5P components in the browser and execute interactive content.

The project reuses some of the mechanisms provided by the existing H5P Drupal module while adapting them to Symfony conventions, lifecycle and components.

Technical challenges

One of the main challenges of the project is adapting a system originally designed around other platforms to Symfony's architecture.

H5P relies on several mechanisms related to storage, libraries, assets, permissions and interactive content execution.

The port therefore requires reproducing or adapting these behaviors without depending directly on Drupal.

Another significant challenge is maintaining compatibility across different Symfony versions.

Framework updates can affect available APIs, service management, routing, dependencies and internal behavior.

The bundle therefore needs to evolve regularly in order to preserve compatibility while minimizing breaking changes for applications using it.

Maintenance and evolution

The project has evolved over time through several improvements and fixes, including:

• adaptation to newer Symfony versions;
• compatibility fixes related to the H5P editor;
• routing and asset-related fixes;
• improvements to H5P package import and download;
• addition of usage data and score storage;
• general dependency and code maintenance.

Open Source

H5P Bundle is distributed under the MIT license.

The source code is publicly available on GitHub and the bundle can be installed in a Symfony project through Composer.

The project is maintained publicly to allow other developers to use it, improve it and contribute to its evolution.
