How to use react-redux-typescript-guide: setup and patterns
Updated · written with AI from the project's own documentation and checked against our catalogue data
react-redux-typescript-guide is an MIT-licensed written guide, with example code, to using React and Redux in a functional style with TypeScript. It focuses on inferring types from the implementation so you write fewer manual annotations while keeping code type-safe. This page walks you through what the guide covers, how to get the example code, and how to use its patterns in your own app.
React & Redux in TypeScript Guidepiotrwitek/react-redux-typescript-guide · ★ 13.3k · MIT Install options & downloads Quick start
- 1Check prerequisites. Install Node.js and Git on your machine. The README lists these as the requirements.
- 2Clone the repository. Run the git clone command from the README to download the guide and its playground.
- 3Open the playground. Go to the /playground folder, which holds the source files for every code example in the guide.
- 4Pick a section to read. Start with the React types cheatsheet, or jump to the Redux section if you are typing actions and reducers.
- 5Compare the guide to your code. Apply the pattern to a small part of your app first, then check it against the strict compiler goal described in the guide.
Who this guide is for
The guide assumes you already know React and TypeScript. It is most useful if you want to add TypeScript to an existing React and Redux app, or if you are learning how to type Redux actions, reducers and connected components.
If you are a complete beginner to React or TypeScript, or you use a different state library or framework, the source suggests you will get less from it, because most content covers React with Redux.
- Good fit: adding TypeScript to an existing React app
- Good fit: typing Redux actions, reducers and connected components
- Good fit: shared typing patterns for components and hooks
- Not a fit: a runnable starter app, since the value is the written patterns
Get the example code: clone the repository
The README's install method is to clone the repository with Git. You need Node.js and Git installed. The repository contains a playground folder with the source files for every code example in the guide.
The clone command from the README is shown below. The README excerpt used for this page does not list further build steps, so check the repository's README for those before you run anything.
- Prerequisites: Node.js and Git
- Playground code lives in the /playground folder
git clone https://github.com/piotrwitek/react-redux-typescript-guide.gitUse the playground to test patterns
The playground is based on create-react-app with TypeScript. The examples are tested against recent TypeScript and third-party type definitions, such as @types/react and @types/react-redux, so you can check that a pattern still compiles against current packages.
The guide also links a Todo-App playground on Codesandbox and a RealWorld example app, if you want to see the patterns running in a browser without a local setup.
- Check the /playground folder against the guide's sections
- Codesandbox Todo-App playground is linked from the README
- React, Redux, TypeScript RealWorld App is linked from the README
Learn the React typing patterns
The guide starts with a React types cheatsheet and then covers function components, class components, generic components, hooks, render props, higher-order components and context. Each pattern shows how to type props and state without repeating types.
Look at the Hooks and Redux Connected Components sections if you want to type useState, useContext, useReducer or a connected counter.
- React.FC and React.Component typing
- React.ComponentProps for reusing a component's props
- Typing useState, useContext and useReducer
- Typing connected components and redux-thunk integration
Learn the Redux typing patterns
The Redux section covers store configuration, action creators, reducers, selectors with reselect and connecting components with react-redux. It also covers typing useSelector and useDispatch.
The guide shows typing reducers both directly and with typesafe-actions, and it includes an async section using redux-observable with typing and testing for epics.
- Store types and store creation
- Action creators, reducers and state immutability at the type level
- Typing reducers with and without typesafe-actions
- Typing epics and selectors
Configuration and tooling
The Configuration and Dev Tools section covers tsconfig.json, ESLint, Jest and a style guide setup with react-styleguidist. The guide's stated goal is complete type safety with the --strict flag, without using type assertions or any.
Related projects by the same author are listed in the README: typesafe-actions for action creators and utility-types for reusable generic types.
- Compiler goal: strict mode with no any or type assertions
- Related libraries: typesafe-actions and utility-types
- Dev tooling: tsconfig.json, ESLint, Jest
What people use it for
- Adding TypeScript to an existing React and Redux app without many manual type annotations
- Typing Redux actions, reducers and selectors in a team codebase
- Setting shared typing patterns for components and hooks across a project
- Looking up how to type connected components with react-redux and useSelector or useDispatch
Frequently asked questions
Is react-redux-typescript-guide free to use?
Yes. The repository is licensed under MIT, as listed on its project page. You can clone it and use the patterns, subject to that licence.
What do I need to install to use react-redux-typescript-guide?
The README lists Node.js and Git as prerequisites. You then clone the repository with git clone. The README excerpt used here does not list further install steps, so check the repository for those.
Is react-redux-typescript-guide a starter app?
No. The main value is the written patterns and examples. The repository has a playground folder with example code, but it is not presented as a runnable app template.
Who should not use this guide?
Complete beginners to React or TypeScript should not start here, because the guide assumes working knowledge of both. It is also less useful if you use a different state library or framework, since most content covers React with Redux.
What are alternatives to react-redux-typescript-guide?
The README lists typesafe-actions, the react-redux-typescript-realworld-app and the Redux Toolkit TypeScript docs as comparable projects. Use typesafe-actions if you only need typed action creators, and the RealWorld app if you want a full example application.
Does the guide cover hooks?
Yes. It has a Hooks section covering useState, useContext and useReducer, and a Typing useSelector and useDispatch section in the Redux part.

Our verdict
Choose this guide if you already know React and Redux and want clear, tested TypeScript patterns that rely on type inference. Pick a different resource if you are new to React or TypeScript, want a runnable starter app, or use a state library other than Redux, such as Redux Toolkit's own TypeScript docs.
