Let me introduce you Immerhin.

• react-nano-state

  1 70 0.0 JavaScript

  Fast state that can be shared across components outside of the React tree.

Immerhin is a very thin abstraction on top of Immer that lets you use basically any state management (Redux-like stores etc.). I am personally using this tiny library react nano state with it.

If you click on the "Try Webstudio" button on webstudio.is, you will see the designer interface that uses Immerhin. While the UI is very alpha, I am curious if you will already find obvious bugs with undo/redo functionality.

  Immutable persistent data collections for Javascript which increase efficiency and simplicity.

  

We have got far, starting with initial attempts using abstractions like immutable which has a severe downside with interoperability. Then we went over to manually cloning objects and arrays using built-in language features like the spread operator, which makes it super unreadable to change complex structures. For example, nested objects or arrays with objects because you have to go inside whatever you want to change and then clone every object on your path to keep the object immutable.

  Create the next immutable state by mutating the current one

  

Immer is the first popular library to solve immutability in an interoperable way. It lets you work with regular objects, so you have no lock-in on Immer and can use vanilla functions that mutate anything you give them without causing any trouble. The most crucial feature of Immer for me, though, is patches generation.
