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;

  }
