This package is auto-updated.

NOTE: This repo is deprecated as of the official 4.0.0 release. It was originally made available for pre-release work so is no longer necessary. If you require a similar setup, install the appstarter repo instead, and manually change composer.json to point to the dev-develop branch.

What is CodeIgniter?

CodeIgniter is a PHP full-stack web framework that is light, fast, flexible, and secure. More information can be found at the official site.

This repository holds a composer-installable app starter. It has been built from the development repository.

This is pre-release code and should not be used in production sites.

CAUTION: This app starter is EXPERIMENTAL, and likely to change before the framework release. We are looking for feedback and suggestions!

More information about the plans for version 4 can be found in the announcement on the forums.

The user guide corresponding to this version of the framework can be found here.

##Installation & updates

composer create-project codeigniter4/devstarter -s dev then composer update whenever you want to pull the latest updates.

Compare your app/Config folder to that inside vendor/codeigniter4/codeigniter4/app/Config, as there could be changes in the latter that need to be copied into yours.


Copy env to .env and tailor for your app, specifically the baseURL and any database settings.

Important Change with index.php

index.php is no longer in the root of the project! It has been moved inside the public folder, for better security and separation of components.

This means that you should configure your web server to "point" to your project's public folder, and not to the project root. A better practice would be to configure a virtual host to point there. A poor practice would be to point your web server to the project root and expect to enter public/..., as the rest of your logic and the framework are exposed.

Please read the user guide for a better explanation of how CI4 works! The user guide updating and deployment is a bit awkward at the moment, but we are working on it!
