The logged_in? method checks if the user is logged-in via a session variable. Helper methods are available in all route handlers and templates. For example, ngrok 4567 will create an public subdomain tunnel to your address localhost:4567, which is the default address for Sinatra’s server.Īt this time, our app only needs read-only permissions from Twitter, but this can be changed in the “permissions” tab of your app in the developer console.īefore progressing to routes and application logic, we must declare a top-level helper method. If you haven’t configured a domain yet, I recommend that you use ngrok to create a secure introspect tunnel to localhost. In the callback URL field, you need to append /auth/twitter/callback to whichever URL you used in the website field. Then, click on the ‘create a new application’ button and fill in the form. This is easily done – just head over to Twitter Developer Console and login using your Twitter credentials. You need to register your app with Twitter.

The last thing we need to initialize before writing any application code is OmniAuth with the Twitter strategy. You can find more information on working with environment variables in Ruby in documentation for the ENV class. I always recommend defining any API keys on a shell-specific level instead of a code-specific level via an environment variable. Note that you must define api_key with the API Key of your Orchestrate application, which can be created or revoked from the Orchestrate Dashboard on a per-application basis. app = Orchestrate::Application.new(api_key)Ĭlient = Orchestrate::Client.new(api_key) In this project, we will use both interfaces, as the object client is simpler and includes everything we need except for the delete operation. The object client uses the method client under the hood, and maps Orchestrate’s domain objects (Collections, KeyValues, etc) to Ruby classes, and is still very much in progress. The method client is a solid but basic interface that provides a single entry point to an Orchestrate Application. The Orchestrate Gem provides two interfaces currently, the method client and the object client. We will use sessions to keep track of whether a user is logged-in or not. Then, we enable one of Sinatra’s many built-in settings, sessions, a fork of Rack::Session::Cookies, “simple cookie based session management”. Generally, I use Bundler to manage my application’s gems, but I won’t include the code for that in this tutorial since there are alternatives, such as dep and just self-managing with gem install. Note that this assumes the two gems are already installed on your system. We’ll include all [ERB templating in our views folder.Īt the top of our main Ruby file, we require the necessary gems for our project. Our main application file will contain all the Ruby code in this tutorial– app.rb. File/Folder Structureįirst, we set up our file/folder directory in a way that Sinatra understands by convention. In this tutorial, we’ll use Sinatra, a popular Ruby web micro-framework and domain-specific language, with OmniAuth Twitter to build an online community titled Twomnistrate where each user shares their favorite phrase as a profile element, stored in Orchestrate. Additionally, the Orchestrate Ruby Client is comprehensive, well-documented, and framework-agnostic. Each strategy is a Rack middleware, so it’s very easy to integrate into your web framework, whether that’s Rails. OmniAuth is a Ruby gem with several strategies, or provider-specific gems, that provides authentication methods for many systems, such as Facebook, Google, GitHub, etc. The use cases of your data may vary, but the process through which the data is stored and accessed is largely the same. A key step in developing an application is handling user authentication and datastore.
