Normalizing State in Redux Applications
- Identify Entities: Break down your application data into distinct entities. These entities could represent different types of objects such as users, posts, comments, etc.
- Normalize Data: Normalize each entity’s data structure. This means organizing related data into separate tables/objects and establishing relationships using unique identifiers (IDs).
- Flatten Structure: Flatten nested data structures to simplify access and updates. Instead of embedding objects within other objects, store references to them using their IDs.
- Create Lookup Tables: Maintain lookup tables or indexes to quickly access specific data by ID. These tables could be objects or maps where keys are IDs and values are the corresponding entity objects.
- Use Selectors: Implement selectors to encapsulate the logic for accessing normalized state. Selectors abstract away the details of state shape, making it easier to retrieve data from the store.
How to Normalize State in Redux Applications ?
In Redux applications, efficient state management is essential for scalability and maintainability. Normalization is a technique used to restructure complex state data into a more organized format, improving performance and simplifying state manipulation.
This article covers the concept of normalization in Redux, exploring various approaches, steps to implement it, and an example application.
