react-redux-typescript-guide: a pattern guide whose examples are compiled in a playground

What react-redux-typescript-guide is, and what it is not

The README calls the project a living compendium documenting patterns and recipes for using React and its ecosystem in a functional style with TypeScript. The stated goal is complete type safety under the --strict compiler flag, without losing type information downstream and without type assertions or hacking with any. A second goal is concision: infer types from the implementation rather than annotating everything, using TypeScript's inference and control flow analysis.

The important framing is that this is documentation. The repository root holds README.md, README_SOURCE.md, a docs directory, a configs directory, a playground directory, and build scripts. The package.json lists only development dependencies: all-contributors-cli, doctoc and husky. React and react-dom appear under dependencies at 18.1.0, which is the version the documentation examples target, not a package consumers install from this repository. If you arrived looking for a React Redux TypeScript install command, there is nothing here to add to your dependency tree. You install React, Redux and their type packages yourself, then read this guide to decide how to shape the types.

The inference-first typing approach the guide argues for

The core argument is that explicit annotations are a cost, and that TypeScript can recover most of what you need from the values you already wrote. Instead of declaring a props interface and then repeating it at the call site, the guide's patterns derive types from components and functions. The React types cheatsheet in the README is the clearest expression of this: it lists React.FC<Props>, React.Component<Props, State>, React.ComponentType<Props>, React.ComponentProps<typeof XXX>, React.ReactElement, JSX.Element, React.ReactNode, React.CSSProperties, React.XXXHTMLAttributes<HTMLXXXElement>, React.ReactEventHandler<HTMLXXXElement> and React.XXXEvent<HTMLXXXElement> as the vocabulary you pick from.

React.ComponentProps<typeof XXX> is the mechanism worth understanding. Rather than maintaining a parallel props type by hand, you extract the props type from an existing component, so a wrapper or a styled variant stays in sync when the original changes. The same idea runs through the Redux sections, where connected components, own props and injected props are separated so that the container does not need to restate what the store already knows. The trade-off is real: derived types are harder to read at a glance than a named interface, and when inference produces something surprising, the error message points at the derivation rather than at a hand-written declaration. The guide accepts that cost in exchange for fewer places where a type can drift out of date.

The playground is how you actually run these patterns

The README states that the playground folder contains all source files of the code examples found in the guide, that they are tested with the most recent version of TypeScript and third-party type definitions such as @types/react and @types/react-redux, and that the playground is based on create-react-app --typescript. The stated purpose is that you can clone the repository and immediately experiment with the component patterns without building an environment yourself.

That is the practical entry point. There is no published package to install, so the steps are cloning and running the playground rather than adding a dependency. The repository's own package.json scripts are for maintaining the README, not for the guide's examples: doctoc regenerates the table of contents in README_SOURCE.md, readme:generate runs node generate-readme.js, and a husky pre-push hook runs ci-check followed by is-git-status-clean. Those scripts tell you how the document is assembled. The README does not document an npm command for starting the playground, so read the playground folder's own package.json before assuming a script name.

Installing nothing: reading the guide and running the playground locally

Because the guide is not a runtime library, the first real use is getting the examples onto your machine. The repository-level scripts are run with npm, and the README shows the doctoc step in the ci-check script as doctoc --maxlevel=3 README_SOURCE.md, which is how the table of contents is regenerated from the source document.

git clone https://github.com/piotrwitek/react-redux-typescript-guide.git
cd react-redux-typescript-guide
npm run ci-check

The ci-check script runs doctoc and then readme:generate, so if you run it you should see README_SOURCE.md's table of contents rewritten and README.md regenerated. That is documentation maintenance, not application code. To work with the examples themselves, move into the playground folder and install its dependencies there, since the root package.json only carries the tooling for the README plus react and react-dom at 18.1.0.

cd playground
npm install

The README does not list a start script for the playground, so check the playground package.json for the available commands before running anything. What you should expect once it runs is the set of components the guide documents: counter components, default-props variants, generic list components, hooks examples for useState, useContext and useReducer, render props, higher-order components, and Redux connected components with and without own props. The value is being able to change a type and watch the compiler react, which is the fastest way to internalize why a pattern is shaped the way it is.

Where the guide stops short

The scope is React and Redux in a functional style with TypeScript, and the README's What's new section reports the guide is updated to support TypeScript v4.6 and typesafe-actions 5.x. That version statement is the guide's own boundary. If your project is on a newer TypeScript release, the examples are a starting point rather than a verified configuration, and the README makes no claim about later versions.

The second gap is ecosystem coverage. The guide's Redux material is built around the classic pattern of action creators, reducers and connect, with typesafe-actions as the complementary library for action creators. Redux Toolkit is not part of the described ecosystem, and neither is any data-fetching or state library outside that list. A team that has already moved to Redux Toolkit's slice model will find the connected-component sections describing a structure they no longer write. That does not make the type-inference advice wrong, but it does mean a meaningful share of the Redux chapters will not map onto the code in front of you. The guide is also prose and examples, so it cannot enforce anything: nothing prevents a codebase from ignoring the advice, and there is no lint rule or config shipped here that would catch a violation.

How it differs from typesafe-actions and utility-types

The README lists three projects in what it calls the React, Redux, TypeScript ecosystem: typesafe-actions, utility-types and react-redux-typescript-scripts. The distinction matters because they are often mentioned together and they do different jobs. typesafe-actions provides typesafe utilities for action creators in Redux and Flux architectures, so it is a library you install and import. utility-types is a collection of generic types for TypeScript that complements built-in mapped types and aliases, described in the README as lodash for reusable types. react-redux-typescript-scripts holds dev-tools configuration files shared between projects based on this guide.

react-redux-typescript-guide itself provides none of that. It is the explanation that tells you when to reach for those libraries and how the resulting types flow through components. If you want something to depend on, you want typesafe-actions or utility-types. If you want to understand how to arrange props, state, dispatch and connected components so that inference does the work, you want this guide. Treating the guide as an installable dependency is the most common category error with a repository shaped like this one.

Maintenance, licence and the cost of following a guide

The repository is not archived, and the last push was on 2026-05-09. The README's own version note points at TypeScript v4.6 and typesafe-actions 5.x, so the upgrade cost of following it is not a dependency bump on your side; it is the reading time needed to check each pattern against your compiler version and your @types packages. The playground is the mechanism that makes that check cheap, since the examples are stated to be tested against current type definitions when the README is generated.

The licence is MIT, which is permissive and places few obligations on reuse of the text and examples, though the usual caveat applies that this is a description of the licence file and not legal advice. One maintenance detail worth knowing if you plan to send a correction: the README is generated. README_SOURCE.md is the editable document, doctoc rewrites its table of contents, and generate-readme.js produces README.md. A husky pre-push hook runs ci-check and is-git-status-clean, so a pull request that edits README.md directly will not survive the repository's own checks. Edit the source, run the generation script, and let the hook verify the result.

Editorial conclusion

Adopt it as a reading and copying reference if you are writing typed React and Redux code and want the component, hooks, HOC and connected-component patterns in one place, with a playground you can clone and run. Do not adopt it if you expected a package: there is no runtime dependency to add, and the guide does not cover Redux Toolkit, RTK Query or modern data-fetching libraries. Before relying on a snippet, check the playground file for that pattern and confirm it still typechecks against the TypeScript and @types versions your project pins, because the README reports the guide is updated to TypeScript v4.6 and that is the only version claim it makes.
