Redux Form is a JavaScript library that connects web forms built in React to Redux, a popular state management system. In a React application, when a user fills in a text field or selects an option, that information needs to be stored somewhere. Redux Form keeps all of that form data inside Redux, the central data store, so it can be read or changed from anywhere in the application. The README includes a notable caution from the library's own author: if you're starting a new project, the community generally advises against storing form state in Redux. The author explains that Redux Form was built around an approach that turned out to have trade-offs, and he later built a separate library to address them. The only situation where Redux Form still makes clear sense, in his view, is when you need form data to be tightly coupled to Redux specifically because other distant parts of the application, like a separate route or page, need to read or modify that data. For teams already using Redux Form in existing projects, the library is mature and well-documented. It supports common form needs: validating user input before submission (either as the user types or on submit), handling lists of repeating fields, building multi-step wizard forms, and loading initial values from stored data. Documentation, examples, and a set of interactive code sandboxes are available online. The project includes video talks explaining the design and has been maintained with community contributions and financial backers. It installs via npm with a single command.
