The first step for building any website is having the right tools. For us, that means setting up a development environment for writing good code.
Many online development courses use in-browser code editors or "sandboxes," which give you the tools and programs needed to accomplish the task at hand and nothing else. You'll use some of these sandboxes throughout the early stages of this curriculum since they're great for getting started quickly. However, the best way to set yourself up for long-term success is to operate in a real development environment.
We won't lie to you: installing packages, editors, and even entire operating systems can be very frustrating. However, having the experience of setting up a development environment to run the code you'll write is an invaluable, real-world skill you'll carry with you for the rest of your career.
In the following sections, we'll go over the steps for setting up your environment. These sections are the most important steps in the entire curriculum. Please take the extra time to double check what you're typing or you may cause more headaches for yourself down the road.
In the next few lessons, we will walk through these installation steps together:
installing the (OS) of your choice;
installing a code editor;
creating an SSH key (a personal "password" that will identify you to GitHub, Heroku, and many other sites you'll be using);
At the end of the next lesson, you'll be up and running with many of the tools you need to write and run code! It may seem like a lot of steps, but we'll get through it as painlessly as possible together! If anything goes wrong, remember to use these steps:
Examine the terminal output for the actual error.
Google, Google, Google.
Never be afraid to !
If you're using a Mac, you're in great shape. This curriculum assumes a Unix-based system. By installing just a few programs, you will be up and running with your education in no time!
A virtual machine is an emulation of a computer that runs within your existing OS. It allows you to use another operating system inside of a program on your current operating system (e.g. Running Linux inside of Windows). Virtual machines are as simple to install as any other program and are risk free. If you don't like Linux, you can easily remove the virtual machine. Virtual machines are a great way for new developers to get started quickly.
Dual-booting means installing two operating systems on your computer, which can give you the option to boot either Linux or Windows when your computer first starts up. The advantage of dual-booting over a virtual machine is that the OS can use all of your computer's resources, resulting in much faster operation. There is some risk to installing a dual-boot system because you're changing your hard drive partitions, but the risk is very low. You'll be okay as long as you take your time and read the instructions.
Dual-booting can be as easy as inserting a flash drive and clicking a few buttons. The benefits of dual-booting cannot be overstated. You will allow Linux to access the full capabilities of your hardware, have a clean and distraction-free environment for coding, and learn the platform used by many senior developers and servers around the world.
"Woah, woah, woah! I like my OS just fine the way it is!"
If you don't have an Apple computer, you are likely using Windows. Don't worry! The options above don't mean you need to get rid of Windows. Linux will gladly share the hard drive with Windows. We know you've probably learned a lot of tips and tricks for your favorite OS and don't want to lose everything you have on your computer. However, most OSs are developed with non-technical folks in mind, so they hide or make it difficult to use many of the languages and frameworks we'll need to install. Having to work around these difficulties causes many new developers to give up before they've even started their journey to full-stack nirvana.
Modifying or dual booting a computer to work with the tools you'll need will make it much easier to start programming, can help create a distraction-free environment, and will look good on your resume. Take a deep breath, and let's look at your options.
Still not convinced? Here are a few great reasons to install Linux:
Tested - We've tested our directions with MacOS, Ubuntu, and official Ubuntu flavors. We did the research so that you can get tools installed with as few issues as possible, getting you to coding sooner. Time spent wrestling with your operating system is time taken from learning how to code.
Community Support - Using the tools we recommend makes it easier for us to help when you run into trouble.
Development Tools Are Built for Linux - Ruby (on Rails) and Node.js, popular backend technologies covered by this curriculum and widely used in the larger web development community, are open source projects that explicitly expect to run on an open-source (UNIX-based) platform like Linux.
Work Like The Pros - Many developers use a Unix-based operating system.
Performance - You are worried about installing Linux because your machine is slow/older and has limited space? When performance is a priority, Linux is a great choice. It uses fewer system resources than Windows and will occupy less hard drive space.
Now let's set up an appropriate development environment!
is a free and open-source operating system that works well with all programming languages. Most development tools are written to work natively with Linux. Your tools will likely be updated more often, have more information available for troubleshooting, and just plain run better on Linux. We'll be using Ubuntu, one of the most popular and user-friendly distributions available, or the lighter weight alternative Xubuntu. If you don't use a Mac, we recommend that you use Linux. It's that simple.
