Developer Tools for the Canvas User

Blog Post created by Robert Carroll on Jul 16, 2018

While collaborating recently, I’ve found myself referring to the Javascript Console, or is it Developer Tools, maybe Web Inspector; what about adding Browser before, do I provide a link? Sometimes, I don’t know whether to provide a link to an article that discusses the particulars of opening, inspecting or getting to the tab I want to reference; or if I’m insulting someone. So, I've decided to create a series of short tutorials that will hopefully walk new developers through some basic tooling around on Canvas with a Browser and JavaScript. I will also try to use these as references in future posts and discussions. I hope they are helpful, feedback is welcome. Enjoy!


Before we get started, let me point out that I won’t be getting lengthy on how to open the tools in each browser since everyone can do that with Google, and the easiest way is to right click the web page and select Inspect Element or Inspect, if you're using Chrome.


The following is a brief, but detailed, and rapidly escalating tutorial of things any Canvas User can do with Developer Tools. Along the way, I will share some community resources that will help guide you with additional information.

 While searching around the community for this series, I stumbled upon this comment by James Jones.


The problem with JavaScript resources is that, for the basic stuff, you're not trying to learn JavaScript, you're trying to accomplish a specific task. There's no book or website that I want to sit through the whole thing to learn how to program in JavaScript. I don't want to start with "Hello world." I don't have time to start with "Hello world." I want to solve the problem that needs solved and get back to life.


My primary resources are the encyclopedia (Mozilla Developer Network documentation) and the commentary on it (Stack Overflow), using Google to get me to the content I need. I often start with a solution from Stack Overflow and then go look up the right way to do it using MDN.

I'll also add that W3 and W3Schools are great resources for what we're doing.


If you have questions or need assistance, please ask in a comment, it will help others.

I wrote this mostly at home, tested, revised, etc. If you work through these tutorials and find any issues please let me know and I will get it fixed right away.


Please let me know if you would like to contribute, I would be happy to add new tutorials and information. Contribute new tutorials with API endpoints that work for user/student roles, no advanced permissions.
