comlink VS Immer

Feels like taking a general Comlink-like system & making it more component oriented. Good ideas. https://github.com/GoogleChromeLabs/comlink

Reminds me of Comlink

Now that we have a way to create PDF files, we can create a web worker to run the renderPDF function in a separate thread. Here’s an example of a web worker that uses comlink to expose the renderPDF function as an asynchronous function:

To streamline the process of configuring the Service Worker and simplify communication between the app and the Service Worker, we will be using the comlink library.

While there's no realistic way to provide a security boundary between JavaScript modules, Workers are a possibility [1].

The code with the more restricted set of permissions must run in the Worker. That code then communicates with the rest of your app through postMessage / SharedArrayBuffer, perhaps using ComLink [2].

The worker API is very simple, you would post a message to the worker. The worker would have the code to process and reply back with the results to the listeners. To make it even easier Google has created the comlink library.

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/)
