Redux

Redux is a predictable state container for JavaScript apps. It helps write applications that behave consistently, run in different environments (client, server, and native), and are easy to test. Redux provides a single immutable state tree, pure reducer functions for state transitions, and a unidirectional data flow pattern based on the Flux architecture. The Redux ecosystem includes React Redux for React bindings, Redux Toolkit for simplified development patterns, and Redux DevTools for time-travel debugging. Redux is widely used with React but can be paired with any JavaScript view library.

Redux is listed with 8 APIs on the APIs.io network. Tagged areas include Flux Architecture, Frontend, JavaScript, Predictable State, and React.

The Redux catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Redux’s developer surface includes engineering blog, Stack Overflow tag, FAQ, and 19 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Open Source Surface applies to this provider. This product is open source and we read its repository directly, so Open Source Surface carries 10 points of the composite. It is scored from what the repository actually publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the provider rather than inferred from our own catalog pointers. This facet adds; nothing was taken away to make room for it. An open-source project is not excused from the commercial facets, because exemption would strip it of the points it does earn. If we have the wrong repository, or this product is not open source, say so on your provider repo and we will drop the facet rather than have you publish against it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 75 points between them, because both conditional facets apply and carry 25 points together. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
