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.

Check out the official documentation for SWR here

SWR: A React Hooks library for remote data fetching. It supports features like caching, revalidation, error handling, prefetching, pagination, and support for SSG and SSR. Its bundle size is 10kb minified and 4.4kb gzipped

SWR Library

For the backend, we chose Python, Django Rest Framework. On the frontend, React, Redux, Saga, Sass. Let’s start with the backend, which was managed by Yegor. He writes about the server part of the project himself.

The whole article properly the best explanation of generators I have come across. This quote stuck out:

> Generators are a special type of function that can return multiple pieces of data during its execution. Traditional functions can return multiple data by using structures like Arrays and Objects, but Generators return data whenever the caller asks for it, and they pause execution until they are asked to continue to generate and return more data.

Applications of generators? I have only used Redux-Saga[1]. Can't even think of other libraries that use them, but would be interested in learning.

redux-saga. The most popular effects library in js

Redux can be extended with a lot of other packages. For example with a side effect manager, you can separate side effects from your business logic, help with error handling and in the same process make testing of side effects a lot easier.

Consumer vs. Producer: Check out Redux Saga

Your app will likely have to deal with async calls like making remote API requests. redux-thunk and redux-saga were created to solve those problems. They may take some time to understand as they require understanding of functional programming and generators. Our advice is to deal with it only when you need it.

Hey thanks for the thoughtful response.

I agree with everything you mentioned here. I'd love to continue to chat with you about how to make testing sagas better.

If you'd like, it would be great if we could move this convo to https://github.com/redux-saga/redux-saga/discussions/2337

If there are dependent API calls, you can probably look at redux-saga. It’s one of the best libraries out there to manage the data.

redux-saga makes use of them in really nice way. https://redux-saga.js.org/ That’s where I’ve used them the most.
