Tree Shaking Principles

When designing code please keep these principles in mind

Enums for features are not-tree-shakable

Here is an example of code which is not tree shakable.

export function query<T>(

studioTeaTwo

// library

type TransformFunction = (rawResponse: object) => object;
type TransformedEntity<T extends TransformFunction> = ReturnType<T
>;

// indivisual

function transform1(rawResponse: object) {
  return {
