react-redux-typescript-guide
The complete guide to static typing in "React & Redux" apps using TypeScript
A recipe book of copy-paste TypeScript patterns for React and Redux apps, covering every common building block from components to async data flows.
This repository is a reference guide for developers building web apps with React and Redux who want to use TypeScript, a version of JavaScript that catches coding errors before the app runs. The guide documents patterns and recipes for keeping code fully type-checked from the user interface layer down through the data management layer, without requiring excessive type annotations throughout.
The guide covers the most common building blocks you encounter in a React and Redux project: function components, class components, generic components, React hooks, context providers, and higher-order components. On the Redux side, it shows how to type your data store configuration, action creators, reducers, and async data flows. Each section presents short, concrete code examples rather than lengthy explanations, so readers can copy a working pattern directly into their own project.
A companion Playground Project lives in the repository's /playground folder. You can clone the repository, open that folder, and run the examples immediately without setting up your own environment. All examples are kept in sync with the latest versions of TypeScript and the relevant type-definition packages, so they reflect current best practices rather than outdated syntax.
The guide also references three companion libraries from the same author: typesafe-actions for creating Redux actions with full type safety, utility-types for reusable generic TypeScript types, and react-redux-typescript-scripts for shared developer tooling configuration. These are separate packages, not bundled inside this repository.
The project was updated to support TypeScript v4.6 and typesafe-actions v5.x. The full README is longer than what was shown.
Where it fits
- Copy a working TypeScript pattern for Redux reducers, action creators, or async flows directly into your project.
- Look up how to add types to React hooks, context providers, or higher-order components without writing boilerplate.
- Run the included playground project to experiment with all patterns without setting up your own environment.
- Migrate an existing React and Redux JavaScript project to TypeScript using the guide's patterns as a reference.
