When you use a router that supports http.Handler you don't have to worry about maintaining special middleware for that library. There are so many well maintained middleware libraries for the http.Handler like https://github.com/gorilla/handlers

To add to this, gorilla also offers some middleware. And its super easy to import your own and wrap it.

Study the generic reader/writer implementations in the io module. (On my system, those sources are in /usr/lib/go/src/io.) The io.Reader and io.Writer interfaces are very simple, but very powerful because of how they allow composition. A shell pipeline like `cat somefile.dat | base64 -d | gzip -d | jq .` can be quite directly translated into chained io.Readers and io.Writers.

Another example of this is how HTTP middlewares chain together, see for example all the middlewares in https://github.com/gorilla/handlers. All of these exhibit one particular quality of idiomatic Go code: a preference for composition over inheritance.

Another quality of idiomatic Go code is that concurrent algorithms prefer channels over locking mechanisms (unless the performance penalty of using channels is too severe). I don't have immediate examples coming to mind on this one though, since the use of channels and mutexes tends to be quite intertwined with the algorithm in question.

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
