You can find a list of all its chapters in the navigation sidebar. This is the first chapter in a step-by-step guide about main React concepts. You might find this guide and the tutorial complementary to each other. If you prefer to learn by doing, check out our practical tutorial. This guide is designed for people who prefer learning concepts step by step. Once you master them, you can create complex apps from small reusable pieces. In this guide, we will examine the building blocks of React apps: elements and components. Most pages in this guide will have editable examples like this one.

Feel free to make some changes, and see how they affect the output. It displays a heading saying “Hello, world!” on the page.Ĭlick the link above to open an online editor. We're first going to create a Rails controller, its initial index view, and tell our Rails app to route requests to “/” to this controller action called “index. The Rails setup also automatically runs “bundle install” - which downloads and installs the default set of RubyGems needed to run your app.Īt this point if you've run into any errors (you shouldn't, in theory, if you've followed your setup tutorial in Step 1 closely) then you'll need to follow what the error messages say and Google around to setup your local environment to be ready ( let us know if you had to do this so we can help others out, too). Here you are creating your “Rails.root” directory (which is ~/apps/OurAgendaApp - remember this!), installing the latest bundler gem and Rails version (without installing the documentation, ‘speeds it up), and then creating your “OurAgendaApp” Rails app folder and files with an assumed Postgresql database connection (we'll get into this more below). ~/apps $ rails new OurAgendaApp -d postgresql

~/apps $ gem install rails -no-ri -no-rdoc ~/apps $ gem install bundler -no-ri -no-rdoc When your working directory changes, this path output will change to let you know where you are at in your file system. The “~” is shorthand for your personal user's home directory. Remember, enter everything after the “$” on each line.
Open your terminal and type in the following (below). Windows users take note that when we say “your Terminal” this means your Git Bash. Windows users will be using Git Bash heavily from here forward, Mac users will use Terminal, respectively. Setup your computer per the applicable tutorial's instructions. If you haven't done this yet, Mac users go here and Windows users go here. Step 1: Ensure your local environment is setup for developing Ruby on Rails apps. When we're done with this and the next two posts, we'll have the foundation of our app ready to receive and merge in the pretty stuff from our visual designer (which we'll do later in this series). This will be a practical, hands-on introduction to a dozen web-app related programming languages, frameworks, and libraries.

We're now at the point in our web and mobile development series where we'll jump right into setting up the app we'll be building step-by-step together.
