The platform’s flexibility, scalability, and extensive feature set make it adaptable to a wide range of data management and content delivery requirements, empowering businesses to leverage their data effectively and drive innovation.

Directus REST API

In addition to its powerful user interface, Directus also provides a robust and flexible RESTful API, allowing developers to interact with data programmatically. The Directus REST API opens up a world of possibilities for integrating Directus with external applications, customizing workflows, and building dynamic and interactive experiences.

The Directus REST API follows the principles of REST (Representational State Transfer) and adheres to industry standards, making it easy to work with and integrate into existing systems. With the API, you can perform various operations, including fetching data, creating records, updating data, and deleting records.

To interact with the Directus REST API, you make HTTP requests to specific endpoints that correspond to different resources and actions. For example, to retrieve data from a table called “products,” you would send a GET request to the /items/products endpoint. Similarly, you can use endpoints like /items, /files, and /users to work with other resources within Directus.

The API supports various request parameters, filters, and sorting options, allowing you to fine-tune your queries and retrieve specific data. You can also perform complex queries using filters, search parameters, and nested filtering options.

Directus provides detailed API documentation that outlines all available endpoints, request methods, parameters, and response formats. It’s a valuable resource for developers looking to integrate Directus with their applications.

By leveraging the Directus REST API, you can build custom integrations, develop mobile apps, create custom dashboards, and synchronize data across multiple systems. The API empowers developers to work with Directus in a way that best suits their needs, providing flexibility and extensibility to the platform.

Whether you’re building a custom frontend application, connecting Directus with third-party services, or automating data workflows, the Directus REST API offers a straightforward and efficient way to interact with your data programmatically.

Remember to refer to the Directus API documentation for in-depth information, examples, and best practices on working with the REST API and leveraging its full potential in your projects.

Getting Started

To get started with Directus, you have at least two options: the free offered Cloud Plan or using Docker Compose. Let’s take a look at both options.

Directus Cloud
Directus offers a Free Cloud plan that allows you to quickly set up and start using the platform without the need for self-hosting. To begin, you can visit the Directus website at directus.io and sign up for a free account. Once registered, you will receive a unique URL that will serve as your Directus instance. This URL will be in the format your-username.directus.site. You can access your Directus instance by navigating to that URL in your web browser.

The Free Cloud plan provides you with a fully managed Directus instance, including regular backups and security updates, making it a convenient option for getting started with the platform.

Docker Compose
If you prefer self-hosting and have experience with Docker, you can deploy Directus using Docker Compose. Docker Compose is a tool that allows you to define and manage multi-container Docker applications. By using the provided docker-compose.yaml file, you can easily set up Directus and its dependencies.

To get started with Docker Compose, you will need to have Docker and Docker Compose installed on your system. Once you have them set up, you can download the docker-compose.yaml file from the Directus GitHub repository or generate one using the Directus CLI.

Here an example, based on:

  • Directus 10.2.1 (main application)
  • Redis 7 (caching)
  • MySQL 8.0.33 (database)
  • Linux (Debian) / MacOS based host
# docker-compose.yaml

version: "3"

services:
    database:
        container_name: ${PFX}-database
        image: mysql:8.0.33
        volumes:
            - ./mysql:/var/lib/mysql
        command:
            [
                "--character-set-server=utf8mb4",
                "--collation-server=utf8mb4_unicode_ci",
                "--default-authentication-plugin=mysql_native_password",
            ]
        env_file:
            - .env 
        networks:
          int:

    # Cache
    cache:
        container_name: ${PFX}-cache
        image: redis:7.0-alpine
        networks:
          int:

    # Directus
    directus:
        container_name: ${PFX}-directus
        image: directus/directus:10.2.1
        restart: unless-stopped
        ports:
            - 8055:8055
        volumes:
            - ./uploads:/directus/uploads
        depends_on:
            - cache
            - database
        env_file:
            - .env
        networks:
          int:
networks:
  int:

In addition, please create a .env file, to pass environment variables for your Directus and MySQL instances and make sure, that both files are within the same directory.

# .env

# Docker Compose

# Prefix of your Docker Compose instances
PFX=directus_dev

# Directus

# Directus Security (see: https://docs.directus.io/self-hosted/config-options.html#security)
KEY=<yourkey>
SECRET=<yoursecret>

# Your FQDN
PUBLIC_URL=""

# Database Configuration

DB_CLIENT=mysql
DB_HOST=database
DB_PORT=3306
DB_DATABASE=<yourdatabase>
DB_USER=<youruser>
DB_PASSWORD=<yourpassword>

# Redis Cache Configuration

CACHE_ENABLED=true
CACHE_STORE=redis
CACHE_REDIS=redis://cache:6379

# Directus Default User and Password (for initial login)

ADMIN_EMAIL=<your@email.com>
ADMIN_PASSWORD=<yourpassword>

# MySQL Database Configuration

MYSQL_ROOT_PASSWORD=<yourrootpassword>
MYSQL_USER=${DB_USER}
MYSQL_PASSWORD=${DB_PASSWORD}
MYSQL_DATABASE=${DB_DATABASE}

# MySQL Database Authentication (optional)
MYSQL_AUTHENTICATION_PLUGIN="mysql_native_password"

Navigate to your folder and start your instance with

docker-compose up -d

Docker Compose will pull the necessary Docker images and start the Directus containers based on the configuration in the docker-compose.yaml file. Once the containers are up and running, you can access Directus by visiting localhost:8055 or the specific IP address and port of your Docker host in your web browser.

Using Docker Compose gives you more control and flexibility over your Directus deployment, allowing you to customize the environment to your specific requirements.

Remember to refer to the Directus documentation for more detailed instructions on setting up and configuring Directus using the Free Cloud plan or Docker Compose.

Hints & Troubleshooting

Unable to upload files within Directus
The volumes created by docker-compose are owned by the current user. You need to change the ownerchip of these folders within the Directus container to node. You can use following command to achieve this.

docker-compose exec -u root <yourpfx>-directus chown -R node:node /directus/database /directus/extensions /directus/uploads

Updating Directus
If you want to update (or downgrade) Directus, you can follow these steps.

  1. Use docker-compose down to stop the instance
  2. Change the version of Directus in your docker-compose.yaml
  3. Start your instance again with docker-compose up -d

The migrations for up- and downgrading will run automatically.
