What is Directus API?

To setup PHPUnit unit testing when developing Directus extensions, follow the steps given below: 

Open the Directus extension's root directory. 

Install PHPUnit via Composer:

In your extension folder, create a directory called ‘tests’ for storing your test files

Create a

 phpunit.xml

) configuration file in your extension’s root directory. Example configuration:

In the ‘tests’ directory, create test classes for your extension. Here's an example

ExampleTest.php 

:

In the terminal, run the following command from your extension's root directory:

To connect Directus to a MySQL database, follow the steps given below: 

If you haven’t installed Directus yet, you can install it via npm or Docker. Here’s the npm installation method:

Directus uses environment variables to connect to a database. To connect to MySQL, you'll need to configure the ‘.env’ file in your Directus project. 

Edit the ‘.env’ file to add the MySQL connection details:

Before running Directus, ensure you have created the MySQL database. You can do this through MySQL command line or a tool like phpMyAdmin:

After configuring the .env file, run Directus to initialize the connection:

Directus will automatically connect to the specified MySQL database, run the necessary migrations, and set up the required schema.

When Directus starts successfully, you can access it via your web browser at

http://localhost:8055

. If the connection to MySQL is working, Directus will load without any database errors.

Directus has multiple default limits, like the The API's default limits on the amount of the items it can return in a single request is 100 whereas, the default limit of the number of queries per second is limited to 50.

Directus is written in JavaScript, primarily using Vue.js and Node.js.

Role scoping is a multitenancy technique in Directus that involves giving each tenant a role and setting each tenant's permissions in a project. Tenants are able to utilize separate schemas or share a single schema by using this.
