Would you hesitate if it is a larger scale project? I have a lot of boilerplate short-keys in my IDE. Redux feels bloaty and requires a lot of boilerplate code to get things done. Obviously RecoilJS makes React state management way easier with the API it provides but there are more we haven't touched yet and we should mention here: So, that was it. For our examples we can use a simple todo list. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. Each atom has a unique identifier, and a default value. We could use useRecoilState hook that exposes a method we can use to update the list accordingly. I've mostly been using redux/sagas for state management with my react and react native projects. The hooks write with react-dom, https://github.com/facebookexperimental/Recoil/blob/master/src/hooks/Recoil_Hooks.js#L24, That means the library didn't support react-native yet. I've mostly been using redux/sagas for state management with my react and react native projects. I inherited one sort of legacy project that used mobx and it seems like a fine choice as well, but I haven't gotten as deep into it. for live data sync). This is a context provider provided by RecoilJS and must be an ancestor of all components that use atoms and selectors: For sure we can have multiple roots and each of them has its own atoms with distinct values. A community for learning and developing web applications using React by Facebook. Recoil lets you create a data-flow graph that flows from atoms (shared state) through selectors (pure functions) and down into your React components. I have done 2 projects now using recoil and have to say that I really like it. . I feel really comfortable with the hooks API. I'd always question if you really need global state in the first place. Time to create a controlled input with the help of React.useState and then take advantage of useRecoilState hook to add new items to our list: So we created a controlled input by using React.useState and every time the form gets submitted we are using setItems method - provided by useRecoilState - to update the list in itemsState atom. Because of this we can run pretty complex logic with the minimum boilerplate: We can wrap our components or parts of the application with an. I am just curious if many of you have used Recoil for state management and about your overall opinions on how it compares to other options. I inherited one sort of legacy project that used mobx and it seems like a fine choice as well, but I haven't gotten as deep into it. Copy link Robert187 commented May 17, 2020. I have to admit that I got amazed with the efficiency, the simplicity and the flexibility it offers. However, similar to server side rendering, it is not officially supported. We’ll occasionally send you account related emails. Let's create a more complex selector by using unfinishedItemsState selector: We added a new one named unfinishedItemsCountState that is pulling unfinished items from unfinishedItemsState selector and returns their length. We keep on using React hooks same as we did before in our components alongside RecoilJS hooks . Here is a small representation that might help ypu visualize what is actually going on with atoms: Sure!! Recoil. privacy statement. Check out the Readme for setup instructions. hm. Looks like you're using new Reddit on an old browser. Press question mark to learn the rest of the keyboard shortcuts. Let's see why. https://github.com/facebookexperimental/Recoil/blob/master/src/hooks/Recoil_Hooks.js#L24, https://github.com/jacques-blom/recoil-test-expo. As declared in RecoilJS docs: Both of these make it difficult to code-split the top of the tree (where the state has to live) from the leaves of the tree (where the state is used). To make it even more clear, we are talking mostly about React.useContext here and not about third party libraries like Redux. The place where I work, we were looking at trying to use context for global state management for a new project, but I ultimately pushed to go back to redux (the devil I know) and that is what we did. There are however a few things were you can still feel that the library is still young and needs some API updates (e.g. RecoilJS uses context to make these outstanding bindings, that is why we need to wrap our top-level App component with RecoilRoot. Another issue is that context can store mostly single values and not complex variations needed by different consumers. The nice thing here is that the counter with the unfinished tasks gets updated automatically whenever we add a new todo item and this is done actually with the minimum effort. Pretty amazing, right? Easy right? One of the issues we face when it comes about state management, is that the children components should constantly inform the ancestors. In recoil I feel that everything is a lot easier. How can we update this list then? Feel free to use this codesandbox I put together with the examples above.
