Question

当尝试从this module扩展Adapter类以用于TS项目时，我遇到了问题。

声明模块，

function memberships_user_membership_saved( $param_1, $param_2 ) {

    $to = 'mail@test.com';
    $subject = 'The subject';
    $body = '<pre>', print_r($param_1, 1), '</pre>';
    $headers = array('Content-Type: text/html; charset=UTF-8');

    wp_mail( $to, $subject, $body, $headers );

}
add_action( 'wc_memberships_user_membership_saved', 'memberships_user_membership_saved', 10, 2 );

扩展

declare module 'socket.io-adapter' {
  import * as Events from 'events';
  import * as SocketIO from 'socket.io';

  export default class Adapter extends Events.EventEmitter {
    constructor(nsp: SocketIO.Namespace);

    nsp: SocketIO.Namespace;

    rooms: SocketIO.Rooms

    sids: { [id: string]: { [room: string]: boolean } };

    encoder: any;

    public add(id: string, room: string, fn?: (err?: any) => void): void;
    public addAll(id: string, rooms: string[], fn?: (err?: any) => void): void;
    public del(id: string, room: string, fn?: (err?: any) => void): void;
    public delAll(id: string, rooms: string[], fn?: () => void): void;
    public broadcast(packet: any, opts: any): void;
    public clients(rooms: string[], fn: (this: this, error: null, sids: string[]) => void): void;
    public clientRooms(id: string, fn: (this: this, error: null, rooms: string[] | null) => void): void;
  }

  class Room {
    sockets: { [key: string]: boolean };
    length: number;
    add(id: string): void;
    del(id: string): void;
  }
}

并尝试使用它

import Adapter from 'socket.io-adapter';

export default class LocalAdapter extends Adapter {}

结果

import SocketIO from 'socket.io';
import LocalAdapter from './LocalAdapter';
...
io = SocketIO(server, { adapter: LocalAdapter });

(alias) SocketIO(): SocketIO.Server (+3 overloads)
import SocketIO

Default Server constructor

好像类没有属性...

文档指出SocketIO.ServerOptions.adapter必须是适配器的类型，它引用的是类而不是实例对象。

我阅读了《定型指南》，但在这种情况下（模块默认情况下会导出一个类），我看不到实现它的方法。

输入输出构造函数的无类型模块
