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?

// Get total `width` of all children
const getAccumulatedChildrenWidth = (helper, parentId) => {
  return helper(self.id).decendants().map(id => helper(id).get())
        .reduce((a, b) => a.data.props.width + b.data.props.width, 0);
}

const Grid = () => {
  return (
    <div>
      {children}
