Redux Toolkit Migration for State Management

2023

Shopify's Retail Point of Sale app migrated from Vanilla Redux to Redux Toolkit (RTK) to reduce boilerplate, improve code readability, and streamline state management. The migration adopted a balanced approach, reusing existing logic while refactoring reducers and thunks to leverage RTK's features like immutable syntax and generated action creators. A hybrid approach was used for asynchronous logic due to GraphQL limitations with RTK Query, utilizing createAsyncThunk with ThunkAPI. Key learnings included explicit typing of hooks and the use of `unwrap` for awaited dispatch calls. The migration resulted in significant code reduction and improved developer experience.

How Migrating from Vanilla Redux to Redux Toolkit Improved State Management in Shopify POS - Shopify

3/31/2023

This post details the migration of Shopify's Retail Point of Sale app from Vanilla Redux to Redux Toolkit (RTK). It outlines the decision-making process, the chosen migration strategy (balanced approach over full rewrite), and the implementation details. Key technical contributions include the coexistence of Vanilla Reducers and RTK Slices, the use of mutable syntax provided by RTK, and a hybrid approach to migrating asynchronous logic using `createAsyncThunk` and ThunkAPI due to GraphQL incompatibility with RTK Query. The post also highlights lessons learned, such as the importance of explicit typing for hooks and using `unwrap` for awaited dispatch calls.
