最近工作上做一些declarative api相关的project，所以趁这机会总结一下目前互联网上能搜到的declarative api相关的资料，不会有涉密的内部信息的lol
什么是declarative呢？
Declarative programming is about what you do, not how you do it.
本质上来说，declarative的世界里，user不再告诉server怎么去做piazza，比如先和面，再放酱料，再放烤箱之类的一系列步骤。instead，你只要告诉server我要一个13inch的夏威夷风味pizza。server知道如何制作pizza，其实就是把一部分logic抽象到server段。
Declarative APIs free developers from reinventing the wheel so that they can focus on creative problems and competitive differentiation.
