• Immer

  141 26,943 7.1 JavaScript

  Create the next immutable state by mutating the current one

  

But is immer really the ultimate answer? The performance problem of immer is more prominent in large arrays and deep-level object scenarios. See this issue description, many authors in the community began to try to make breakthroughs, and noticed that structura and mutative, I found that it is indeed many times faster than immer as they said, but it still fails to solve the problem of both fast speed and good development experience. I will analyze the two issues in detail below.

• concent

  7 1,288 9.7 TypeScript

  A reactive atomic state engine for React like.

  

At the end of 2021, I started to conceive the v3 version of the state library concent, one of the key points is to support deep dependency collection (v2 only supports the first collection of state One-layer read dependency), then you need to use Proxy to complete this action in depth, and use immer in depth to find that viewing drafts in debug mode is very frustrating, and you need to use JSON.parse(JSON.stringify(draft)) to complete, although it was later discovered that the current interface can export a draft copy and view the data structure, but it really annoys me to insert extra current and then erase it at compile time, and current itself has a lot of problems Overhead, plus the following similar performance problems of immer found through issue
