What Hacker News says?
Yep. The Redux core `createStore` function can be distilled down to about 25 lines [0], and the rest of the core lib can be added in another 75-ish [1]. I've seen Redux described as "a pattern with really good documentation", and there's some truth to that. On the other hand, we've put a _lot_ of work into React-Redux in particular [2] to make sure it's optimized and works well with React. As a side note, we have a…

HN discussionExactly - that's what we've already built for web development at https://replay.io :) I did a "Learn with Jason" show discussion that covered the concepts of Replay, how to use it, and how it works: - https://www.learnwithjason.dev/travel-through-time-to-debug-...

HN discussionYou're conflating several different things: patterns specifically recommended by the React team, patterns in vogue in the community, specific libraries from the community, and actual API changes in React itself. The React team did definitely tell folks to stop using mixins and try using HOCs instead [0]. HOCs have some limitations as well, and hooks are designed to help address those [1], but it doesn't mean HOCs ar…

HN discussionHi! I maintain Redux and am deeply involved in the React community, and have spent a lot of time both critiquing the React team's decisions and explaining their decisions to the community. I actually wrote exactly that blog post and did a conf talk on it earlier this year. I covered why the React team switched to directing users to use "frameworks" to build React apps, the development influences behind React Server…

HN discussionSagas are a great power tool, but most Redux apps don't need them. That's why we opted to include thunks out of the box as part of our official Redux Toolkit package: https://blog.isquaredsoftware.com/2020/02/blogged-answers-wh... (You can still customize the middleware when using RTK to set up your store, same as always, so if you want to use sagas you still can.) That said, there's a lot of things thunks _can't_ d…

HN discussionPer Dan's suggestion, you should start with the actual docs. After that, I keep a big list of links to high-quality tutorials and articles on React, Redux, and related topics, at https://github.com/markerikson/react-redux-links . Specifically intended to be a great starting point for anyone trying to learn the ecosystem, as well as a solid source of good info on more advanced topics. It includes links for learning c…

HN discussionI'm not sure I follow your first point. What's the meaning and issue with "updates only happen on explicit state updates? Per the "non-React components" aspect: wrapping up non-React code into components is actually something React is pretty good at. The typical implementation of a maps lib wrapper component would have React render a single div with a ref, then use `componentDidMount` to initialize the plain JS lib…

HN discussionI'm sorry to hear that your experience has been negative so far. There's a commonly repeated phrase that "Redux is a pattern, not a framework". Redux doesn't have anything built in for actually updating the state, or defining an application architecture. Redux primarily provides a pattern for separating the write logic from the rest of the app conceptually, and adding centralized behavior on top of that via middlewa…

HN discussionThat's a technically legal use of Redux. Redux doesn't care if you have an action object that only contains a type + some values and do all the work on the reducer side, or precalculate the new state before dispatching the action and have the reducer simply blindly merge in whatever was provided. Redux simply calls the root reducer function, and saves the root state value it returns. There's actually prior art for w…

HN discussionAs a Redux maintainer, I'll toss out my obligatory reminder you can use as much or as little abstraction on top of Redux as you want. Don't like writing action constants by hand? Use `redux-actions` to generate action creators that have an overriden `toString()`. Don't like touching multiple files? Use the "ducks" pattern. Want something that adds additional layers on top so you don't have to write a lot of reducers…

HN discussionFWIW, I'm the current Redux maintainer, and that is an absolutely horrible and unfair description of how Redux was created. Elm was _an_ influence on Redux, but there were many other influences as well. Dan Abramov's prior experience did include some VB (possibly VB.NET, I think), but also a lot of actual JS. See the actual "History of Redux" and "Prior Art" docs pages, and a couple of my blog posts, for an accurate…

HN discussionHi, I'm a Redux maintainer. Anything specific that confused you? Which tutorials were you looking at? We're currently planning a revamp of the Redux docs. I'd really appreciate any feedback on what things caused problems, so we can know how to make the docs better. Feel free to comment here, or ping me on Twitter or in the Reactiflux chat channels. I've also got a survey open asking for suggestions on docs structuri…
