Creating an Embeddable Javascript Widget

One of the updates I’m working on for WhichBeach is the ability for other website owners to embed WhichBeach widgets that will display up-to-date beach data. This is very much a work in progress, but I’d like to share.

I’ve never done anything like this before, so I thought I’d start by taking some inspiration from Facebook’s Like Button implementation:

To break it down, Facebook’s script injects a new script tag that pulls in their Javascript SDK. They’re also ensuring that the script is only injected once into the page.

I think I can make this work for me too:

Great. Now all that’s left is to write a Javascript SDK! I’ll need to expose that on /js/sdk.js and add all my widget logic in there.

In due time… if anyone has any tips and resources that they think I should be using – let me know in the comments!
