There was a problem hiding this comment. are you avoiding using a templating system here for any reason? There was a problem hiding this comment. Just trying to keep the example as simple and small as possible. The focus of the example is meant to be the interactions with the SDK, so I didn't want to add in anything fancy with templating. I'm open to hearing other options though - whatever makes the example as simple and digestible as possible. @richgilbank thoughts? There was a problem hiding this comment. just chatted with tyler in person - verdict was that it makes sense to not add an additional dependency for an example. |

Should this live in its own file maybe? Keep large blobs out of the index?
I don't feel strongly either way.

It's such a small example that I think we should keep it all in the same place. Keeps the example as straight forward as possible
