Roadiz is a modern CMS based on a polymorphic node system which can handle many types of services and contents. Its back-office has been developed with a high sense of design and user experience. Its theming system is built to live independently of back-office allowing easy switching and multiple themes for one content basis. For example, it allows you to create one theme for your desktop website and another one for your mobile, using the same node hierarchy. Roadiz is released under MIT license, so you can reuse and distribute its code for personal and commercial projects.

Documentation

Headless edition

This is the API-ready edition for Roadiz. It is meant to set up your Apache/Nginx server root to the web/ folder, keeping your app sources secure, and all your business logic into src/ folder AKA \App PHP namespace.

Headless edition does not need any themes, so you can build your API schema right into the backoffice and use REST API entry points without any code. A built-in tree-walker is configured automatically to walk your node-types children fields to create a JSON graph when requesting a single node (by id or by slug).

Headless edition is heavily based on roadiz/abstract-api-theme features, you will find additional information about registered routes and API entry points on its readme. AbstractApiTheme is already registered for you so you can begin creating your data structure right away. Any additional configuration is available in your src/AppServiceProvider.php container service-provider.

Automatic node-source controller resolution is disabled and any request on a node-source path will end up in src/Controller/NullController.php, so your application clients have to use your secure API end-points.

Boilerplate for exposing content API for static-site generators

Headless edition has been built to work with a NuxtJS application and minimizing API calls.

The most important call you'll make is the Get single node-source by path which combine searching a node-source by its path and fetching its content in single data context.

To retrieve homepage, you can execute GET /api/1.0/nodes-sources/by-path?path=/:

{
    "slug": "homepage",
    "@type": "Page",
    "node": {
        "nodeName": "homepage",
        "home": true,
        "visible": true,
        "tags": [],
        "attributeValues": []
    },
    "translation": {
        "locale": "en"
    },
    "urlAliases": [],
    "title": "Homepage",
    "metaTitle": "Homepage – Headless",
    "metaKeywords": "",
    "metaDescription": "Homepage – Headless",
    "url": "/",
    "@id": "http://headless.test/api/1.0/page/2/en",
    "head": {
        "siteName": "Headless",
        "homePageUrl": "/"
    }
}

This is way more efficient than executing :

  • /api/1.0/nodes-sources?path=/ which is a hydra:Collection response
  • and then once you know @id, you can request a single node-source response: /api/1.0/page/2/en

You'll find some boilerplate models and controller for serving common contents for building menus and finding social links. For example: /api/1.0/common will expose CommonContentResponse model which can be customized to expose some useful data that could be painful to fetch through NodesSources API endpoints, such as hierarchical menu views, or Roadiz settings.

{
    "mainMenuWalker": {
        "children": [],
        "item": {
            "slug": "main-menu",
            "@type": "Neutral",
            "node": {
                "nodeName": "main-menu",
                "visible": false,
                "tags": []
            },
            "title": "Main menu",
            "@id": "http://headless.test/api/1.0/neutral/1/en"
        },
        "@type": "MenuNodeSourceWalker"
    },
    "head": {
        "siteName": "Headless",
        "homePageUrl": "/"
    }
}

Usage

Use ready-to-go Docker image

If you do not need any custom code or to version your content schema, you can launch a Roadiz headless with our Docker standalone image and our docker-compose.standalone.yml example stack.

Override ./app/conf/config.yaml file if necessary (for Solr configuration or custom monolog handler)

docker-compose up -d --force-recreate
docker-compose exec -u www-data app bin/roadiz migration:migrate --allow-no-migration -n
docker-compose exec -u www-data app bin/roadiz install -n --env=install 
docker-compose exec -u www-data app bin/roadiz generate:private-key
docker-compose up -d --force-recreate --no-deps app varnish
docker-compose exec -u www-data app bin/roadiz users:create -m johndoe@roadiz.io -b -s -p "supersecretpassword" johndoe 

Then browse to https://headless.test/rz-admin and build your headless API.

Standalone code is configured to create a CommonContentResponse from a main-menu node. If you need to customize common content responses, we invite you to create a custom project.

Create a new custom project

For custom projects we recommend starting from a dedicated repository:

# Create a new Roadiz project on develop branch
composer create-project roadiz/headless-edition;
# Navigate into your project dir
cd headless-edition;

Composer will automatically create a new project based on Roadiz and download every dependency.

Composer script will copy a default configuration file and your entry-points in web/ folder automatically and a .env file in your project root to set up your Docker development environment.

Develop with Docker

Docker on Linux will provide awesome performances, and a production-like environment without bloating your development machine:

# Copy sample environment variables
# and adjust them against your needs.
nano .env;
# Build PHP image
docker-compose build;
# Create and start containers
docker-compose up -d;
# Initialize database and base content
docker-compose exec -u www-data app bin/roadiz migration:migrate --allow-no-migration -n
docker-compose exec -u www-data app bin/roadiz install -n --env=install 
# Restart to empty caches
docker-compose up -d --force-recreate --no-deps app varnish
Issue with Solr container

Solr container declares its volume in .data/solr in your project folder. After first launch this folder may be created with root owner causing Solr not to be able to populate it. Just run:
sudo chown -R $USER_UID:$USER_UID .data (replacing $USER_UID with your local user id).

Develop with PHP internal server

# Edit your Makefile "DEV_DOMAIN" variable to use a dedicated port
# to your project and your theme name.
nano Makefile;

# Launch PHP server
make dev-server;

On Linux

Pay attention that PHP is running with www-data user. You must update your .env file to reflect your local user UID during image build.

# Type id command in your favorite terminal app
id
# It should output something like
# uid=1000(toto)

So use the same uid in your .env file before starting and building your docker image.

USER_UID=1000

Update Roadiz sources

Simply call composer update to upgrade Roadiz packages. You’ll need to execute regular operations if you need to migrate your database.

Maximize performances for production

You can follow the already well-documented article on Performance tuning for Symfony apps.

Optimize class autoloader

composer dump-autoload --optimize --no-dev --classmap-authoritative

Increase PHP cache sizes

; php.ini
opcache.max_accelerated_files = 20000
realpath_cache_size=4096K
realpath_cache_ttl=600

Build a docker image with Gitlab Registry

You can create a standalone Docker image with your Roadiz project thanks to our roadiz/php80-nginx-alpine base image, a continuous integration tool such as Gitlab CI and a private Docker registry. All your theme assets will be compiled in a controlled environment, and your production website will have a minimal downtime at each update.

Make sure you don’t ignore package.lock or yarn.lock in your themes not to get dependency errors when your CI system will compile your theme assets. You may do the same for your project composer.lock to make sure you’ll use the same dependencies' version in dev as well as in your CI jobs.

Headless Edition provides a basic configuration set with a Dockerfile:

  1. Customize .gitlab-ci.yml file to reflect your Gitlab instance configuration and your theme path and your project name.
  2. Enable Registry and Continuous integration on your repository settings.
  3. Push your code on your Gitlab instance. An image build should be triggered after a new tag has been pushed and your test and build jobs succeeded.
