基于这种抽象,能合理的将编译器拆分为三阶段:FrontEnd,Optimizer, Backend,从而实现能兼容各种语法形式的语言,更易于迁移并兼容不同架构的cpu。见下图: 3阶段编译 这三个阶段围绕这IL(intermediate language)进行。IL语言隔离了语法(能轻易适配各种新的语种),平台架构等的差异性。 3阶段编译架构 2.2 Dart的编译流程 ...

For example, Apple's network request libraryNSURLSessioncan restrict access to Wi-Fi only or require a VPN to connect. To support these use cases, we created a new network request package:cupertino_http, which is based on the new Objective-C interop mentioned in the previous section, and f...
Persistence of the frontend_server process comes into play when developer requests hot reload: in this case frontend_server can reuse CFE state from the previous compilation and recompile just libraries which actually changed. Once Kernel binary is loaded into the VM it is parsed to create ...
And Dart is not the only option if you want to share code between backend and frontend. Go, for example, can be compiled to JavaScript with GopherJS. O'Caml with BuckleScript. Java with, among others, J2CL. The list goes on. All of these currently offer better AOT performance than Dart...
a web socket backend by developing a browser game. You will learn to implement quite complex reactivesystems while avoiding pitfalls such as circular dependencies by moving the RxJS logic from the frontend to the backend. The book will then focus on writing extendable Rx code by developing a...
frontend_server 将 Dart 源码编译成内核文件,然后通过 flutter 工具发送给设备。当开发者请求热重载的时候,这个持久化的前端服务就开始发挥作用,在这种情况下,前端服务可以重用之前一次的编译状态,只编译那些变化的文件。 一旦内核二进制被加载到了 VM 里面,他会被解析,然后创建多个代表了不同程序实体的对象。然而这...
