EECS 1720 Extension Starter Pack

You probably need to know these

Start here.. what is DOM??

Anatomy of an extension?

• (this is firefox but any operating system is related - they all use manifest.json and they all need to request premissions)

---

OK but what can I do ?

Does it matter which Browser?

manifest.json

• Firefox

• Chrome

Permissions

Best by example? These go together:

1. asking for activeTab permission

2. how to check if a browser tab is currently active

This concept carries through to other actions you may be interested in and so need to ask permissions for.

Namespace! A key difference

Switching browsers? Unsure what works where? See if what you are doing is incompatible?

---

OK so what about other “.js” stuff?

Like… adding p5.js to your extension? (It is like adding your external.js file only with many more pre-defined function options for drawing, images, sound etc.)

Did you want an example of aesthetic + technical?

Maybe this Chris¹ can help you think about aesthetic concepts?

---

Some specific questions you may be asking?

1. Can I find a use for the whole HTML document, as a string?

2. Do I need to check if this JavaScript Object is a DOM Object?

3. What if I want to do something with the files, do I need to know the file extensions?

4. Can I get a list of Chrome variables?

• In general you should be careful with concepts like asking for ALL OF THE EVERYTHING
  • if implemented inefficiently… things can freeze!
