Oh 這個有用,讓 mocha 支援 snapshot testing
但需要踩踩雷
jihchi 10:37:41
XD 結果是 snapshot 有用,case 無用
mrorz 10:41:08
支援 snapshot 要做的工比 case 多很多吧 XD?

Compilers are the New Frameworks

My current "investment thesis" is that what we call web frameworks are transforming from runtime libraries into optimizing compilers. When it comes to eking performance out of hand-authored JavaScript and accompanying runtime libraries, we've reached the point of diminishing returns.

mrorz 10:19:39
重點應該不是 `return`
而是只有 `await` 遇到 rejected promise 才會 throw 吧⋯⋯
jihchi 10:21:02
> We discussed `return` implicitly awaiting promises but decided against because it's hard to opt out and returning rejected promises has uses
mrorz 10:22:27
所以現在第 13 行的 `main()` 呼叫會回傳一個 rejected promise。然後出現 unhandled promise rejection
jihchi 10:23:09
yep
mrorz 10:23:36
我是覺得 await 才會把 rejected promise 轉成 throw 還算單純
mrorz 10:23:58
不過 return 時自動 await 也是一個有趣的思維

@jihchi 你可以跟我講一次 appier-create-react-app 裡面有啥嗎
jihchi 10:51:46
css-modules 跟 absolute path
jihchi 10:51:48
沒了
jihchi 10:53:25
還有 react-hot-loader
mrorz 10:58:07
react-hot-loader 不是 create-react-app 內建的嗎
我怎麼印象中還有 redux-duck 以及 immutable-js?
jihchi 10:59:55
CRA 預設 hot reload 是靠 webpack HMR
mrorz 11:00:44
好喔好喔
雖然我不清楚差別 XD
jihchi 11:00:45
redux-duck &amp; immutable.js 不需要動到 config,是出廠預設幫你安裝,但不是必要
jihchi 11:01:34
最大差別在 React 的 state persistence
Michael Hsu 11:04:12
請問一下
上次聽你們也有用 react-app-rewired
? 哪個做法比較好呢
jihchi 11:05:18
看情況。
jihchi 11:06:45
rewired 是為了 transition 使用。
jihchi 11:08:01
有時候讓 legacy project 可以先用 customized CRA,配上 rewired。
Michael Hsu 11:10:17
那你們怎麼決定要把哪些拉進
fork 版的 CRA
像有些不同專案沒用 redux 用 apollo 怎辦
jihchi 11:11:14
主要是考量要不要改到 wepback / babel / etc. 這些 tools config
jihchi 11:11:45
redux, immutable 這類都是 package,不用改 config 也能支援
jihchi 11:12:14
除非你想用像是 lodash 配上 babel plugin 做些額外優化功能,那才會動到 CRA
jihchi 11:13:31
Ideally,我個人是覺得盡量用原生 CRA 就好。慢慢的有其他替代方案,就可以淘汰掉客製 CRA
jihchi 11:13:58
eg. css-modules v.s. styled-components
jihchi 11:14:17
最近你貼的 macro 就很 promising
Michael Hsu 11:14:51
對啊 有了 macro 就方便多了
jihchi 11:15:15
有點想偷跑放在客製 CRA,不過 macro 的 packages 現在比較少,我們目前需要的地方還不多,所以還沒偷跑
Michael Hsu 11:16:31
偷跑也不錯
像css modules 支援討論串超長
等了好久
jihchi 11:17:48
嗯,其實裝下去也沒差,弄個怪獸 CRA 也不是不行。要看你的需求。目前 css-modules 是普遍接受的解法,就放進去。
mofas 21:16:17
@jihchi 有支援.less 和plain .css嗎?
jihchi 21:43:21
@mofas less 不支援,要用 rewired 加。plain CSS 要用 global 去寫,src 裡面預設開 css-modules
