Um, hello, MobX? You don't have to like it but it has 6x the weekly downloads as Recoil does, so it should at least be mentioned.

react-redux : Integration with React

You should think about using some client state management libraries like Redux. Redux gives you the possibility to encapsulate states and manipulate it through functions. https://react-redux.js.org/

`useSyncExternalStore` was shipped live in React 18.0 and is fully ready for production use.

Source: I'm the primary Redux maintainer, and worked with Andrew Clark of the React team to nail down the semantics and behavior needed by `useSyncExternalStore` in practice. They had the idea, but discussed a lot of the necessary use cases with us and other lib maintainers, and a lot of its internal implementation is directly related to how React-Redux's `useSelector` hook was implemented already.

I built the first working code that used it by prototyping React-Redux v8's switch from our own internal subscription handling to `useSyncExternalStore` instead and gave Andrew feedback:

State Management with Redux

Redux is a popular state management tool that can be used in conjunction with React to manage the state of an application. It works by implementing a unidirectional data flow, in which actions are dispatched to a central store, which then updates the state of the application and sends the updated state back to the components that need it.

tl;dr; Previously here, I wrote about how to write a modern web application using Rails as a full-stack framework. Just writing HTML and Vanilla Javascript. Now we will go ahead creating a React client App using NextJs. The existing API has the following endpoints: GET /api/kit/products(.:format) POST /api/kit/products(.:format) GET /api/kit/products/:id(.:format) PATCH /api/kit/products/:id(.:format) PUT /api/kit/products/:id(.:format) DELETE /api/kit/products/:id(.:format) Enter fullscreen mode Exit fullscreen mode In the new project, we have the same screen as before: We have a lot of customized components: src/components/ ├── Form │ ├── Actions.tsx │ ├── Input.tsx │ └── index.tsx ├── Layout │ ├── Page.tsx │ ├── Sidebar.tsx │ └── index.tsx ├── Loading.tsx ├── LoadingOverlay.tsx ├── Notification.tsx ├── Products │ ├── Form.tsx │ └── Sidebar.tsx └── SearchList ├── Form.tsx ├── ListItem.tsx └── index.tsx Enter fullscreen mode Exit fullscreen mode But our pages are simple and short. For example, take a look at the products page code: Highlights **NextJs is just a choice, not a requirement **The API made using Ruby on Rails is completely independent of the Next JS client application developed with NextJs. You could use any RESTfull client application to consume the existing API. In my project, I am using the NextJs project as a subfolder of my Rails repository, but you could put it anywhere. Why Next JS **I already worked with React Router and React Navigation, but when I knew the **Next/Router and all related features, as the **Next/Link**, I loved it. We can use partial load and caches. Get more info here. **Conventions **You can create your own convention for your own projects. But, in my opinion, it is beneficial to use a convention that is popular and validated in production by many other developers. Like Ruby on Rails, NextJs gives you a directory structure, core resources (link, routes, image, etc.) and rich documentation. **SSR **After to create a few projects using SPA, it doesn’t seem to me a good choice for big projects. So, for now, I am using SSR with NextJs. The main use of SSR is to improve the SEO, but like this approach to offer the a better UX. **React Query is the link between the Rails and NextJs **Working together with Axios (my code), it is a great option to consume the REST API (and GraphQL). You have the access to: isLoading, isError, data, error, and others. It is a very easy way to load data and rescue errors. **React Context **I don’t like https://react-redux.js.org/, it brings a complexity to the project that I don’t think soo is a good thing. But we can use the React Context and React Reducer to offer a store and events to manager states of the application. You can see the it on the project here https://github.com/raphox/rails-7-fullstack/tree/nextjs/frontend/src/contexts/products. *React components with namespace **It is something that I learned recently. I used it in my project to offer a way to override children of some components and prevent to set many properties throth the parent. Like in the following code: In the previous code, we have the namespace *SidebarPrimitive with nested Root, Header, and List components. I am using the Root component to wrap the content and I am passing the props to the respected child. **Tailwind **There are controversies related to it, but trust me, create a project using it and make sure that you don’t like or love it. Dependencies: https://tailwindcss.com/ “Tailwind CSS works by scanning all of your HTML files, JavaScript components, and any other templates for class names, generating the corresponding styles and then writing them to a static CSS file.” https://www.radix-ui.com/docs/primitives/utilities/slot “Merges its props onto its immediate child.” https://tanstack.com/query/ “Powerful asynchronous state management for TS/JS, React, Solid, Vue and Svelte” https://axios-http.com/ “Axios is a simple promise based HTTP client for the browser and node.js.

Sorry, that is correct. I was combining Redux toolkit with React Redux In my head.

if you have a more complex component hierarchy, and the component who receives the DB response is not on the top, you might consider introducing a State management tool, such as Redux: https://redux.js.org / https://react-redux.js.org

FWIW I was actually the primary alpha tester for useSyncExternalStore - I prototyped using uSES in React-Redux v8, and worked with Andrew Clark to nail down what the final API and behavior should be.

Additionally, the idea that the props.todoAdded() version from connect automatically dispatched when called was always a source of confusion and led to lots of questions. So, Dan Abramov specifically suggested that we drop the idea of auto-binding as we were designing the hooks API to make it more clear what's actually happening, and we did.
