actionhero Initializer的优先级

actionhero 的Initializer 是包含了优先级的，对于一些场景下我们是需要关注的

参考定义

src/classes/initializer.ts

export abstract class Initializer {
  /**The name of the Initializer. */
  name: string;
  /**What order should this Initializer load at (Default: 1000, Actionhero core methods are < 1000) */
  loadPriority?: number;
  /**What order should this Initializer start at (Default: 1000, Actionhero core methods are < 1000) */
  startPriority?: number;
  /**What order should this Initializer stop at (Default: 1000, Actionhero core methods are < 1000) */
  stopPriority?: number;
 
  constructor() {
    this.name = null;
    this.loadPriority = 1000;
    this.startPriority = 1000;
    this.stopPriority = 1000;
  }

启动以及停止使用

src/classes/process.ts

 if (!loadInitializerRankings[initializer.loadPriority]) {
          loadInitializerRankings[initializer.loadPriority] = [];
        }
        if (!startInitializerRankings[initializer.startPriority]) {
          startInitializerRankings[initializer.startPriority] = [];
        }
        if (!stopInitializerRankings[initializer.stopPriority]) {
          stopInitializerRankings[initializer.stopPriority] = [];
        }
 
        if (initializer.loadPriority > 0) {
          loadInitializerRankings[initializer.loadPriority].push(
            initializeFunction
          );
        }
        if (initializer.startPriority > 0) {
          startInitializerRankings[initializer.startPriority].push(
            startFunction
          );
        }
        if (initializer.stopPriority > 0) {
          stopInitializerRankings[initializer.stopPriority].push(stopFunction);
        }

说明

actionhero Initializer 的优先级还是比较重要的，比如开发了好多，有些是有依赖关系的，如果阅读actionhero源码的话也会
发现不少使用此定义的，比如chatroom的

 
export class ChatRoomInitializer extends Initializer {
  constructor() {
    super();
    this.name = "chatRoom";
    this.loadPriority = 520;
    this.startPriority = 200;
  }
