ducks-modular-redux VS Immer

And here's an interesting proposal for organizing data store/reducer logic: https://github.com/erikras/ducks-modular-redux

Yeah, the "ducks" file structure has been around as an idea since 2015, but most Redux apps (and our older docs) used a "folder-by-type" pattern (/reducers/todos.js, /actions/todos.js, etc).

The official Redux Style Guide suggests using the (very modular) Ducks structure. Essentially, this structure follows the design pattern of "New Feature? New folder." I am not 100% sure, but this seems to be a newer development in Redux best practices. For example, favesound-redux splits files into "type" folders.

That's an idea that has been around for awhile and was popularized by the Duck pattern for Redux.

The original Redux docs examples did show a "file-by-type" folder structure (ie, /actions/todos.js, /reducers/todos.js, etc), but you've always been able to structure your code however you want to. The "ducks" pattern was invented right after Redux came out, and has always been a valid approach.

Immer is a lightweight package that simplifies working with immutable states. Immutable data structures ensure efficient data change detection, making it easier to track modifications. Additionally, they enable cost-effective cloning by sharing unchanged parts of a data tree in memory.

It looks like it’s mutating, but both the reducers and update() uses immer* under the hood, so we still respect immutability under the hood.

Cami supports redux devtools so you can use that for time-travel debugging too!

I heard that immutability libraries like immer.js [0] help with this. Anyone go this way and had good success? Is this 'the way'?

So, that's what we built, and we built it in the most obvious way — using JavaScript Proxy objects to track mutations and reflect those changes across Appsmith’s framework. Initially things looked good — it worked, aside from a few hacks to make some data types work with map and set, and we were following the example of other projects that had similar requirements. If it was good enough for them, it should be good enough for us, right?

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.

I like immer for this kind of thing: https://github.com/immerjs/immer

It gives you immutable updates without getting bogged down in FP abstractions.

I've always been a huge fan of immer for these case. For your code, it would simply turn into setGridData((prev) => produce(prev, draft => applyChanges(changes, draft)) but I recommend you go over their documentation to fully understand how it works

If you're trying to make things actually immutable, Object.freeze and deep copies can clutter things up pretty good, have you considered using something like immer? (https://immerjs.github.io/immer/)
