What do people build with it?

USE CASE 1

Flatten deeply nested API responses into normalized Redux state so related records are easy to look up and update consistently.

USE CASE 2

Define a schema for your API data so Normalizr automatically extracts entities and their relationships into separate lookup tables.

The explanation does not specify a license.

In plain English

Normalizr is a JavaScript library that takes nested JSON data, for example, an API response where objects contain other objects, and flattens it into a normalized structure according to a schema you define. This makes it easier to manage relational data in state management systems like Redux or Flux, where deeply nested structures can be difficult to update consistently. The README notes that Normalizr is no longer actively maintained due to the original author's inability to find a new maintainer, though the library itself is described as stable and has been used by thousands of projects without issue. Users who need additional features or find a bug are advised to fork the repository and maintain their own version.

Copy-paste prompts

Prompt 1

Show me how to use Normalizr to normalize an API response with nested user and post objects for use in a Redux store.

Prompt 2

Write a Normalizr schema for an e-commerce API response that contains nested orders, each with line items and a customer object.

Prompt 3

Demonstrate how to denormalize data back from a Normalizr-structured Redux store so I can render nested objects in my components.

Prompt 4

My Redux state has deeply nested objects that are painful to update. Show me how Normalizr would restructure this data so updates are a single reference change.

Prompt 5

Walk me through adding Normalizr to an existing React plus Redux project step by step, from installing to defining the first schema.
