Template Files

The provided source files (in Template/) should be considered guidelines for your own use, as they may need changing to fit your environment. These are based on the following assumptions:

1. Your default repository branch is set to develop
2. You use Composer to manage all necessary dependencies
3. Your source code is located in app/ (for projects) or src/ (for libraries)
4. Your unit tests are located in tests/
5. Your CodeIgniter dependency is codeigniter4/framework (some paths need to be changed for dev-develop)

Workflows

This kit includes a number of workflow templates for integrating GitHub Actions into your library or project development process. To add these to your repo simply copy the workflows into a Template/.github/workflows/ directory.

[!TIP] The source files also include a configuration for Dependabot which will help keep your dependencies and workflows updated.

Below is a brief description of each workflow; see the links above for help with each tool.

Deptrac

Requires depfile.yaml

Deptrac is a "dependency tracing" tool that allows developers to define which components should be allowed to access each other. This helps keep your project architecture logical and concise by enforcing the rules you set. For example, you may want to impose an MVC-style architecture by allowing a Controller to use any Model but not vice-versa.

Infection

Requires infection.json.dist

Just because your tests reach a high level of code coverage does not mean they are comprehensive. Mutation Testing is a way of gauging the quality of your unit tests. A silly example: your code has an increment function with a single unit test for 100% coverage:

Infection will re-run your unit test against "mutated" versions of your code that should cause failures and report "escaped mutations" when they still pass. In this example, Infection mutates your increment() function to use - instead of +, but since your test case still asserts 42 as the result it is considered an "escape" and you should plan to add more tests.

PHPCPD

PHP Copy-Paste Detector analyzes your code and reports when there are blocks of duplicate code more than a certain number of lines long (default: 5). In most cases this is a sign of poor code structure and an opportunity to consolidate classes or functions.

PHP CS Fixer

PHP CS Fixer is used to enforce coding standards. Once the rules are defined in the config file the workflow will check your code against the definitions and fail for any deviance.

PHPStan

Requires phpstan.neon.dist

Static analysis is a major factor in catching bugs and issues before they happen. PHPStan will analyze your code for mistakes based on the configuration supplied.

PHPUnit

Requires phpunit.xml.dist

Unit testing automates running your code through all the possible scenarios before putting it into use in production. PHPUnit is a highly-configurable framework and suite for writing and running unit tests. This workflow also configures PHPUnit to report on code coverage and upload the results to Coveralls.io (you will need a free account, but it is also fine to use this workflow without Coveralls).

Rector

Requires rector.php

Rector provides automated refactoring of code, allowing you to make sweeping updates based on predefined rulesets. Rector can be highly opinionated based on its configuration file (rector.php) so be sure to read the documentation and figure out the best fit for you. This workflow performs a "dry run" to check for any changes that Rector would have made and fail if there are matches.

[!NOTE] Rector updates rules all the time, so you may want to lock your repo to the latest known working version of Rector to prevent unexpected failures. Using pinned version in composer.json and update it with dependabot is the best practice.

Unused

Composer Unused does one thing: checks that your code actually uses the dependencies you have included via Composer. It can be easy to forget to update your composer.json when your code drops a dependency, so this workflow will help track those down.

Hosting with Vagrant

[!NOTE] The Vagrantfile.dist is unmaintained. It might not work now. Contributions are welcome.

Virtualization is an effective way to test your webapp in the environment you plan to deploy on, even if you develop on a different one. Even if you are using the same platform for both, virtualization provides an isolated environment for testing.

The codebase comes with a src/Template/Vagrantfile.dist, that can be copied to Vagrantfile and tailored for your system, for instance enabling access to specific database or caching engines.

Setting Up

It assumes that you have installed VirtualBox and Vagrant for your platform.

The Vagrant configuration file assumes you have set up a ubuntu/bionic64 Vagrant box on your system:

Testing

Once set up, you can then launch your webapp inside a VM, with the command:

Your webapp will be accessible at http://localhost:8080, with the code coverage report for your build at http://localhost:8081 and the user guide for it at http://localhost:8082.

Example Files

Besides the template files, this repo includes some examples for integrating CodeIgniter with other third-party resources. These files (in Examples/) may change over time and should not be relied on for anything more than a reference for your own code.
