Prerequisite
feature toggle
因為使用多個branch做開發,有時候有些branch太早開發,但太晚merge進去,中間會有很多其他小開發完成,這樣就會產生merge conflict。
這時候就要去處理這樣的問題
但feature toggle可以有相關的解方。
feature切換
常常button換顏色的時候要換來換去,這樣也很苦惱
feature toggle 優勢與特色
toggle type
是第二個好方法,最終要去盡量避免
Flagship4j
LINE Taiwan 開發的,已經開源出來了
open feature
有三個特點:
openFlagr
AB testing,用go來撰寫的。performance非常的好。

第一個是未完成Code 的 Merege 問題
第二個是新需求的Adopt,新舊功能都留著
Invisibility
Speed
Experimentation
Safety
Live Update
Realse Toggle : 承上
Ops Toggles : 流量大有另外函數
Permission Toggles : 權限控制
Experiment Toggles : 使用者體驗
Toggle remove
toggle測試結束的時候最終要拿掉,不然會累積太多很難處理,會把code跟toggle feature一起拿掉。
testing
基本上會希望非開發人員可以去處理,QA或是project owner可以去改變跟測試
Demo step

create a controller with openfeature client
create flag setting on the openflagr UI (release toggle)
