Getting Started

Step 1: Clone the project

Using your terminal, navigate inside the directory you want to download the project files into. Make sure that the directory is empty before proceeding to the download process. Once there, run the following command:

git clone .

Step 2: Install project's dependencies

composer install

Step 3: Development mode

If you're installing the project for development, make sure you have development mode enabled, by running:

composer development-enable

You can disable development mode by running:

composer development-disable

You can check if you have development mode enabled by running:

composer development-status

Step 4: Prepare config files

  • duplicate config/autoload/cors.local.php.dist as config/autoload/cors.local.php <- if your API will be consumed by another application, make sure configure the allowed_origins
  • duplicate config/autoload/local.php.dist as config/autoload/local.php
  • duplicate config/autoload/mail.local.php.dist as config/autoload/mail.local.php <- if your API will send emails, make sure you fill in SMTP connection params
  • optional: in order to run/create tests, duplicate config/autoload/local.test.php.dist as config/autoload/local.test.php <- this creates a new in-memory database that your tests will run on

Step 5: Setup database

Running migrations:

  • create a new MySQL database - set collation to utf8mb4_general_ci

  • fill out the database connection params in config/autoload/local.php under $databases['default']

  • run the database migrations by using the following command:

    php vendor/bin/doctrine-migrations migrate

This command will prompt you to confirm that you want to run it:

WARNING! You are about to execute a migration in database "..." that could result in schema changes and data loss. Are you sure you wish to continue? (yes/no) [yes]:

Hit Enter to confirm the operation.

Executing fixtures:

Fixtures are used to seed the database with initial values and should be executed after migrating the database.

To list all the fixtures, run:

php bin/doctrine fixtures:list

This will output all the fixtures in the order of execution.

To execute all fixtures, run:

php bin/doctrine fixtures:execute

To execute a specific fixture, run:

php bin/doctrine fixtures:execute --class=FixtureClassName

Step 6: Test the installation

php -S -t public

Sending a GET request to the home page should output the following message:

  "message": "Welcome to DotKernel API!"
