Notes

• 区分 Client 和 Server
  • @osjs/client
  • @osjs/server
• 动态加载的内容有 Client 和 Server 部分

  • CoreBase
    • 作为 OS 的核心 容器/IoC 容器/运行上下文
  • providerHandler - 创建容器
    • IoC 依赖容器
    • 基于 async-dependency-graphGitHubchriswoodle/async-dependency-graph

• 应用 注册逻辑
  • 类型: theme, icons, sounds, application
  • 先 preload，然后应用内通过 osjs.register(name,callback) 注册回调到 Packages
  • Packages preload 完成后触发 注册的 回调
  • callback 入参为 core, args, options, metadata
• 应用
  • 创建 osjs/application 作为主要 进程
    • 通过 proc 创建 window - 获取到可渲染的 $content
    • 创建 osjs/basic-application 作为 event-bus
      • 提供标准操作 - dialog, vfs 操作
      • 渲染到 $content
      • vfs 操作触发事件到 event
        • new-file
        • save-file - 实际保存操作
        • open-file - 实际读取文件
