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/)

If you want to set up from Context, Zustand is your best bet. It offers an extremely simple API that lets you create a store with values and functions. Then, you can access that store from anywhere in your application to read and write values. Reactivity included! If you want to store nested object data in your store, consider using Immer alongside Zustand to easily change nested state.

Now, it's time to consume our API. We'll use React for this tutorail, but feel free to use any other framework you prefer; the process remains the same. Additionally, we'll utilize SWR to fetch data from the API and TypeScript to ensure type safety.

'use client'; import FormPostUpdate from './components/FormPostUpdate/FormPostUpdate'; import FormDelete from '../app/components/FormDelete/FormDelete'; import { useFetch } from './hooks/useFetch'; import { useFetchSWR } from './hooks/useFetchSWR'; import Chart from './components/Chart/Chart'; export default function Home() { // Uncomment the code below and comment out the "useFetch" code if your want to use SWR for data fetching --> https://swr.vercel.app/docs/with-nextjs // const { data, error, isLoading } = useFetchSWR( // 'http://127.0.0.1:8000/api/anime/' // ); // Uses the Fetch API for data fetching const { data, error, isLoading } = useFetch( 'http://127.0.0.1:8000/api/anime/' ); if (error) return

An error has occurred.

; if (isLoading) return

Loading...

; console.log(data); return ( <>

POST: Add Anime Form

UPDATE: Update Anime Form

Select an ID from the list. You can change the data for Anime ID, Name and Release.

DELETE: Delete Anime Form

GET: Anime Data List

{data.map((anime) => (

• {anime.anime_name}

• ID: {anime.id}
• Anime ID: {anime.anime_id}
• Anime Release Year: {anime.anime_release}

))}

); }

There are libraries like SWR, RTK Query, and React Query that simplify the data fetching process on the client and take care of the state, error handling, caching, and re-fetching for you.

Then install the package SWR into your application with the following command:

SWR

I would suggest taking a look at SWR [0]. I think it strikes a very nice balance between using fetch and something more heavy-handed like React Query.
