Normalized Data Structure

A very simple library to make it easier to work with Redux Normalizing State Shape, in an immutable way.

Written in typescript.

Structure

byId: Simple "dictionary", where the object key is the items unique identifier allIds: Array of all unique identifiers

• forEach: loop through each item
• map: map items returning a new Array
• filter: filter items, returning a new Array
• set: add an item by key, over-writing any previous item
• addItems: add a array of items to the structure. Takes either a keyof T or a selector function that returns a string to specify the structure key.
• removeItem: Remove item by key
• fromArray: creates a new "normalized" object from an array. Takes either a keyof T or a selector function that returns a string to specify the structure key.
• toArray: get all items as an array
