System Design Cheatsheet

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

  1. Clarify and agree on the scope of the system
  • User cases (description of sequences of events that, taken together, lead to a system doing something useful)
    • Who is going to use it?
    • How are they going to use it?

Getting started with Node.js

"How do I get started with Node?" is a commonly heard question in #Node.js. This gist is an attempt to compile some of the answers to that question. It's a perpetual work-in-progress.

And if this list didn't quite answer your questions, I'm available for tutoring and code review! A donation is also welcome :)

Setting expectations

Before you get started learning about JavaScript and Node.js, there's one very important article you need to read: Teach Yourself Programming in Ten Years.

Understand that it's going to take time to learn Node.js, just like it would take time to learn any other specialized topic - and that you're not going to learn effectively just by reading things, or following tutorials or courses. _Get out there and build things!

Some useful JCR queries (XPATH, SQL2) for AEM/CQ development.

SQL2

All nodes with a specific name

SELECT * FROM [nt:unstructured] AS node
WHERE ISDESCENDANTNODE(node, "/search/in/path")
AND NAME() = "nodeName"
