References — fw-01 mini-redux, and Reading an Entire Production Library

Primary sources first. Read the real implementation after you have written yours, never before.

The library itself

• redux/src — small enough to read completely in an afternoon, which is exactly why it is the first source-reading exercise. Start with createStore.ts and combineReducers.ts.
• applyMiddleware.ts — the function-composition trick worth understanding properly
• Redux Toolkit — what the ecosystem actually uses now, and why the original API needed wrapping

Design background

• Dan Abramov — Redux: the first 30 seconds and the three principles
• Flux architecture — the predecessor Redux compressed into one store
• Elm architecture — where the model/update/view loop came from
• Dan Abramov — You Might Not Need Redux — by the author; the honest cost accounting

Alternatives worth comparing

• Zustand — the same problem with far less ceremony
• Jotai · Valtio — atom-based and proxy-based takes
• XState — when the state is genuinely a machine
