Codefii is a stunningly fast high-level web framework that encourages rapid development and includes everything needed to create database-backed web applications.
Under the hood, codefii has a generic admin called FiiA that helps in managing database records. it's somewhat known as active admin.
Before anything else, you need a copy of composer installed on local machine through composer.For existing applications you can run the following:
composer create-project --prefer-dist codefii/codefii myApp
After a successful installation of the codefii components, the next thing is to navigate to your app directory and serve / run your app by using:
cd myApp
php fii --serve
then visit your browser and type:
localhost:8080
cd myApp
php fii --serve --port=your_port_number
