Just about every week, we see someone wander into chat and ask:
I'm having trouble getting UserFrosting to work on (insert some obscure web hosting service). Can anyone help me?
The first thing I do is ask them - have you been able to get it to work locally? More often than not, it turns out that they haven't even tried - in fact, they don't even have a local development environment set up!
If you're not sure what "local development environment" means, then please continue reading.
You don't need special hardware to run a web server. PHP, Apache, nginx, MySQL - these are all free open-source projects that you can install and run on just about any computer. When you pay your $60/year for Jimbo's Web Hosting, Inc., you're not paying for the software. You're paying for storage and bandwidth on a machine that is (hopefully) running in a well-maintained data center, with 24/7 uptime. Some of your money might also go to paying for basic sysadmin tasks, like updating software, maintaining mail servers, etc.
The 24/7 uptime is critical for your live application - no doubt about that. But for developing your application, you don't need to run and test it on a computer in a data center. In fact, there are several reasons why this is a terrible idea:
Convenience. I've seen people who write their code in a text editor or IDE, but then upload their code to their hosting service and refresh the page at their live URL to "test" their code. This introduces an entire extra step into your development cycle. And what a pain it is! It's much easier if you can just test your code directly on your own machine.
Security. There are all sorts of opportunities for PHP to inadvertently disclose sensitive data, like database passwords and API keys. This is especially true if you are dumping stack traces to the response, which many PHP installations and frameworks do by default! Developing in a local environment that only you can access ensures that you'll have the opportunity to iron out these vulnerabilities before the application goes live.
Ultimately, you should not think of writing code as the only activity involved in building a website. Making a website or web application really consists of two distinct phases: development and production, each of which should happen in their own separate environments and involve automated testing, managing dependencies, compiling assets, and a variety of other tasks.
In this same vein, any framework or CMS that has you do a "one-click install" is fundamentally framing the problem in the wrong way. There is no such thing as "installing" a web application. Rather, a web application is developed and then deployed. By missing this crucial distinction, you lose out on the ability to maintain your application and roll out changes in an organized, controlled, and sane way.
If you think that setting up a local environment is too much work, think again! On a MacOS or Linux computer, setting up a local environment simply consist of installing a couple of apps through the command line. On a Windows 10 or 11 machine, an additional step is required : Installing the Windows Subsystem for Linux (WSL2)!
And the sprinkle on the cupcake is the next chapter will teach you how to do everything yourself!
If you don't have a computer on which you can install a full solution stack natively, or you want to develop in an environment that more closely resembles your production environment, consider using Docker. When using Docker, you only install one app on your computer : Docker Desktop.
Docker allows you to run software in packages called containers. Because Docker containers are lightweight, you can run several containers simultaneously. What's more, Docker containers can actually link up their virtual file system to your native OS's file system. This makes it easy to write code on your "real" machine, and then run it in the virtual environment instantly without having to actually copy it over.
Docker makes abstraction of what environmental changes you have configured on your machine. When using Docker, you create a whole environment and this travels with your project. If your colleague needs to work on it, they can use the same Docker configuration and have your project running on their machine within minutes. Docker can also be used for continuous integration testing and even into production. In every step, you are sure to use the exact same configuration. The risk of a feature working on your machine, but not your colleague computer are minimal.
To get started with Docker, head over to our documentation on development environments.
Even after you have a local development environment set up, you'll still need a way to collaborate with the rest of your team and, when you're ready to launch, push your code to a live server.
It turns out that
git, the popular version control software, can be used to do both! For collaborating with your team, we suggest that you set up a free private repository on Github. You should agree upon a proper git flow, and each member of your team should have their own local development environment.
