It looks like the Typed Gem is deprecated, however this is such a small library we really don't need a gem for it. The steps for implementing the Typed.js library are as follows:
Copy the JavaScript code from the library
You can access the Github page and grab the raw JavaScript code here.
Once you have that, you can create a new file in the application, such as:
If you haven't already created a lib directory, you can do that by running:
Copy the raw JavaScript code from the Typed.js repo into the new typed.js file. And then call it from the application.js file, like this:
Now let's create some some coffeescript code file, we'll call it typed-implementation.coffee
that will perform the 'typing':
And then call it right below the call to the typed.js library in the application.js file:
Now, all we have to do it add a new span tag that contains the element class that our Coffeescript code is looking for:
And you should now have a great looking 'typed' element on your site!
