어떤 문제가 있나요

우리의 서버로 하나의 request가 들어오면 서버는 응답을 처리하기 위해 필요한 여러 API를 호출하고 데이터를 가공하여 필요한 응답을 돌려줍니다. requset는 동시에 여러개 들어오기 때문에 우리는 request마다 어떤 작업을 수행했는지 그룹핑하여 모니터링하는 것이 필요합니다. 가장 일반적인 방법으로는 요청마다 requestID 를 생성해 할당하고 수행하는 작업마다 requestID 를 함께 기록하여 requestID 단위로 그룹핑해 확인하는 것입니다.

이러한 패턴은 Ruby on rails 나 Python Django 같은 플랫폼에서 매우 간단하게 구현할 수 있는데, 각 request는 하나의 thread에 할당되어 동기로 처리되기 때문에 requestID 와 같은 요청 정보는 thread context 에 저장하여 필요할 때 꺼내 사용하면 되기 때문입니다.

In the olden days, HTML was prepared by the server, and JavaScript was little more than a garnish, considered by some to have a soapy taste.

After a fashion, it was decided that sometimes our HTML is best rendered by JavaScript, running in a user's browser. While some would decry this new-found intimacy, the age of interactivity had begun.

But all was not right in the world. Somewhere along the way, we had slipped. Our pages went uncrawled by Bing, time to first meaningful paint grew faster than npm, and it became clear: something must be done.

And so it was decided that the applications first forged for the browser would also run on the server. We would render our HTML using the same logic on the server and the browser, and reap the advantages of both worlds. In a confusing series of events a name for this approach was agreed upon: Server-side rendering. What could go wrong?

In dark rooms, in hushed tones, we speak of colours.

Storybook 6.2 includes experimental Webpack 5 support. Webpack 5 brings a variety of performance improvements, as well as exciting new features like module federation. Here's a quick guide to get you going.

Intro

Replacing Create React App with the Next.js CLI

How dare you make a jab at Create React App!?

Firstly, Create React App is good. But it's a very rigid CLI, primarily designed for projects that require very little to no configuration. This makes it great for beginners and simple projects but unfortunately, this means that it's pretty non-extensible. Despite the involvement from big names and a ton of great devs, it has left me wanting a much better developer experience with a lot more polish when it comes to hot reloading, babel configuration, webpack configuration, etc. It's definitely simple and good, but not amazing.

Now, compare that experience to Next.js which for starters has a much larger team behind it provided by a world-class company (Vercel) who are all financially dedicated to making it the best DX you could imagine to build any React application. Next.js is the 💣-diggity. It has amazing docs, great support, can grow with your requirements into SSR or static site generation, etc.

	// I'm tired of extensions that automatically:
	// - show welcome pages / walkthroughs
	// - show release notes
	// - send telemetry
	// - recommend things
	//
	// This disables all of that stuff.
	// If you have more config, leave a comment so I can add it!!

	import {useEffect} from 'react'
	import {RecoilRoot, useRecoilState, atom} from 'recoil'

	// User data

	const user1 = {username: 'joe', bio: "You will never see me, unless of course this example is totally broken."}
	const user2 = {username: 'bob', bio: "I am the one true user."}
	const user3 = {username: 'fred', bio: "Just kidding, make way for the new guy."}

	// Recoil atom to store user. The default user is user1, but it will be

	//
	// useTime hook
	//
	import { useEffect, useState } from 'react';

	export const useTime = (refreshCycle = 100) => {
	// Returns the current time
	// and queues re-renders every `refreshCycle` milliseconds (default: 100ms)

	const [now, setNow] = useState(getTime());
