### Redux-Saga 游戏编程

**利用 fork-model & channel 管理复杂的前端游戏逻辑(❤️Saga)**
* 这里以 [shinima](https://github.com/shinima) 开源的 [battle-city](https://github.com/shinima/battle-city) 作为分析项目
* 这个项目是由 Redux-Saga 深度驱动的，几乎涉及到了 Redux-Saga 使用的方方面面。
* 虽然没有用 Canvas 渲染，但它诠释了一种不错的游戏前端逻辑开发的模式(fork-model & channel)。

#### 状态模型分析，一切从建模开始^_^

### NodeJS

<details>
 <summary>
 NodeJs 是什么？
 </summary>
 <ul>
 <li>Node.js is a `JavaScript runtime` built on Chrome's V8</li>
 <li>Node.js uses an event-driven, `non-blocking I/O` model</li>
 </ul>
</details>

<details>
 <summary>
 非阻塞I/O
 </summary>
 <ul>
 <li>阻塞：I/O 时进程休眠等待 I/O 完成后进行下一步</li>
 <li>非阻塞：I/O 时函数立即返回，进程不等待 I/O 完成</li>
 <li>I/O 操作非常慢</li>
 </ul>
</details>

<details>
 <summary>
 事件驱动
 </summary>
 <ul>
 <li>I/O 等异步操作结束后的通知</li>
 <li>观察者模式</li>
 </ul>
</details>

<details>
 <summary>
 为什么偏爱 NodeJS
 </summary>
 <ul>
 <li>前端职责范围变大，统一开发体验</li>
 <li>在处理高并发，I/O密集场景性能优势明显</li>
 </ul>
</details>

<details>
 <summary>
 web 常见场景
 </summary>
 <ul>
 <li>静态资源的读取</li>
 <li>数据库操作</li>
 <li>渲染页面</li>
 </ul>
</details>

<details>
 <summary>
 高并发应对之道
 </summary>
 <ul>
 <li>增加机器数(堆机器并不合算)</li>
 <li>增加每台机器的 CPU 数----多核</li>
 </ul>
</details>

<details>
 <summary>
 进程
 </summary>
 <ul>
 <li>进程（执行中的程序）：是计算机中的程序关于某数据集合上的一次运行活动，是系统进行资源分配和调度的基本单位</li>
 <li>多进程：启动多个进程，多个进程可以一块执行多个任务(CPU 调度算法快速的切换)</li>
 </ul>
</details>

<details>
 <summary>
 NodeJS 工作模型
 </summary>
 <ul>
 <li>Client --> EventLoop(single thred) --> Non-blocking Worker(internal C++ threadpool)</li>
 <li>一个 NodeJS 进程只开一个线程</li>
 </ul>
</details>

<details>
 <summary>
 线程
 </summary>
 <ul>
 <li>线程：进程内一个相对独立的，可调度的执行单元，与同属于一个进程的线程共享进程的资源</li>
 <li>多线程：启动一个进程，在一个进程内启动多个线程，这样，多个线程也可以一块执行多个任务（靠调度算法来做）</li>
 </ul>
</details>

<details>
 <summary>
 NodeJS 的单线程
 </summary>
 <ul>
 <li>单线程只是针对主进程，与I/O 操作系统底层多线程调度没啥关系</li>
 <li>单线程并不是单进程（用 cluster 模块，CPU 有几个核儿，我们就启几个进程）</li>
 </ul>
</details>

<details>
 <summary>
 常用场景
 </summary>
 <ul>
 <li>Web Server</li>
 <li>本地代码构建(性能不是最好，但对前端友好)</li>
 <li>实用工具开发(性能不是最好，但对前端友好)</li>
 </ul>
</details>

<details>
 <summary>
 快速 Demo 演示
 </summary>
 <ul>
 <li>VSCode + Code Runner</li>
 </ul>
</details>

#### CommonJS

包裹函数，不用自己写，NodeJS 帮我们弄好了

```js
(function(exports, require, module, __filename, __dirname){
    console.log('test.');
});
```

<details>
 <summary>
 CommonJS 特性
 </summary>
 <ul>
 <li>每个文件是一个模块，有自己的作用域</li>
 <li>在模块内部 module 变量代表模块本身</li>
 <li>module.exports 属性代表模块对外接口</li>
 </ul>
</details>

<details>
 <summary>
 require 规则
 </summary>
 <ul>
 <li>`/` 表示绝对路径，`./` 表示相对于当前文件的</li>
 <li>支持 js、json、node 拓展名，不写依次尝试</li>
 <li>不写路径则认为是 build-in 模块或者各级 node_modules 内的第三方模块</li>
 </ul>
</details>

<details>
 <summary>
 require 特性
 </summary>
 <ul>
 <li>module 被加载的时候执行，加载后缓存</li>
 <li>一旦出现某个模块被循环加载，就只输出已经执行的部分，还未执行的部分不会输出</li>
 </ul>
</details>

<details>
 <summary>
 module.exports 与 exports 的区别
 </summary>
 <ul>
 <li>exports 是 module.exports 的快捷方式</li>
 </ul>
</details>

<details>
 <summary>
 global

 <ul>
 <li>CommonJS</li>
 <li>Buffer、process、console</li>
 <li>timer</li>

 process 模块常用 API 
 </summary>
 <ul>
 <li><a href="https://nodejs.org/dist/latest-v10.x/docs/api/process.html">文档</a></li>
 <li>process.argv</li>
 <li>process.argv0</li>
 <li>process.execArgv</li>
 <li>process.execPath</li>
 <li>process.env</li>
 <li>process.cwd()</li>
 <li>process.nextTick(()=>{})</li>
 </ul>
</details>

#### nextTick VS setTimeout VS setImmediate

```js
setImmediate(() => console.log('setImmediate'));
setTimeout(() => console.log('timeout'), 0);
process.nextTick(() => {
    console.log('nextTick1')
    process.nextTick(() => console.log('nextTick2'))
});
// nextTick1
// nextTick2
// timeout
// setImmediate
// nextTick 是放在当前事件队列的最后，主意这个不能出现递归，不然其它异步都会异常
// setTimeout 放在 nextTick 和 setImmediate 中间
// setImmediate 是放在下一个事件队列队首
```
