三.应用加载状态 - 生命周期

export const NOT_LOADED = "NOT_LOADED"; // 没有加载过
export const LOADING_SOURCE_CODE = "LOADING_SOURCE_CODE"; // 加载原代码
export const NOT_BOOTSTRAPPED = "NOT_BOOTSTRAPPED"; // 没有启动
export const BOOTSTRAPPING = "BOOTSTRAPPING"; // 启动中
export const NOT_MOUNTED = "NOT_MOUNTED"; // 没有挂载
export const MOUNTING = "MOUNTING"; // 挂载中
export const MOUNTED = "MOUNTED"; // 挂载完毕
export const UPDATING = "UPDATING"; // 更新中
export const UNMOUNTING = "UNMOUNTING"; // 卸载中
export const UNLOADING = "UNLOADING"; // 没有加载中
export const LOAD_ERROR = "LOAD_ERROR"; // 加载失败
export const SKIP_BECAUSE_BROKEN = "SKIP_BECAUSE_BROKEN"; // 运行出错

export function isActive(app) { // 当前app是否已经挂载
    return app.status === MOUNTED;
}
export function shouldBeActive(app) { // 当前app是否应该激活
    return app.activeWhen(window.location);
}

标注应用状态

import { NOT_LOADED } from './app.helpers';
apps.push({
    name: appName,
    loadApp,
    activeWhen,
    customProps,
    status: NOT_LOADED // 默认应用为未加载
});
