Grab our runtime dependencies

Grab our runtime dependencies

We’ll need to grab Knockout itself, as well as something called RequireJS. RequireJS is a library that enables us to load modules at runtime asynchronously.

There are several ways we can go about this:

1. Download the files manually and host them.
2. Download the files through a package manager like Bower and host them.
3. Use a Content Delivery Network (CDN) to host both files.

We’ll keep it simple and go with the first option, but Knockout’s documentation has details on using a CDN, and more libraries like RequireJS can be searched for on cdnjs.

Let’s create an externals folder in the root of our project.

mkdir externals

Now download Knockout and download RequireJS into that folder. The latest and minified versions of the files should work just fine.
