#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?

Observable React elements with RxJS

When I just started using RxJS with React, I was subscribing to observables in componentDidMount and disposing subscriptions at componentWillUnmount.

But, soon I realised that it is not fun to do all that subscriptions(that are just updating property in component state) manually, and written mixin for this...

Later I have rewritten it as "high order component" and added possibility to pass also obsarvers that will receive events from component.

But, shortly after, I realised that for server side rendering, I need to do something quite complicated(in order to wait until all data would be loaded, before rendering - actually, I was building an isomorphic application, and still working on it).

data1 = lambdaMap(data, "*", 3);
//lambdaMap *3: 3,6,9,12,15
trace("lambdaMap *3:", data1);

data1 = lambdaMap(data, "==", 3);
//lambdaMap ==3: false,false,true,false,false
trace("lambdaMap ==3:", data1);

data1 = lambdaMap([[1,2,3],[1,2]], "+", [4,5]);
//lambdaMap [[1,2,3],[1,2]] +[4,5]: [[1,2,3,4,5], [1,2,4,5]]
