如何创建自己的类型DefinitelyTyped，其中默认为类

Question

我想创建我自己的排版DefinitelyTyped来排名项目(https://github.com/maxcnunes/ranking)

我已经尝试了一些实现如下..。

declare module 'ranking' {
  interface RankingPlayer {
    position: number
    score: number
    playerId: any
  }

  interface Ranking {
    maxScore: number
    branchFactor: number
    players: any
    find(query);
    findOne(query);
    setScore(player: RankingPlayer);
    addPlayerPoints(player: RankingPlayer);
  }

  interface RankingStatic {
    (config: any): Ranking;
  }

  var ranking: RankingStatic;

  export = ranking;
}

当我尝试使用代码时

import Ranking from 'ranking'
...
console.log(Ranking) // This out '[Function: Ranking]'
const ranking = new Ranking({}) // This Error 'Cannot call a class as a function'

所以我再用下面的密码..。

declare module 'ranking' {
  interface RankingPlayer {
    position: number
    score: number
    playerId: any
  }

  export default class Ranking {
    maxScore: number
    branchFactor: number
    players: any
    constructor(config: any)
    find(query)
    findOne(query)
    setScore(player: RankingPlayer)
    addPlayerPoints(player: RankingPlayer)
  }
}

并尝试使用代码

import Ranking from 'ranking'
...
console.log(Ranking) // This out 'undefined'
const ranking = new Ranking({}) // This Error 'ranking_1.default is not a constructor'

不知道该怎么做才能实现这一点：

Answer 1

Ranking似乎是一个类，所以我也将其定义为：

custom-typings/ranking.d.ts

declare module 'ranking' {
  class Ranking {
    constructor(options?: {})
  }
  export = Ranking
}

然后你就可以这样说：

app.ts

import Ranking = require('ranking');
const ranking = new Ranking({
  maxScore: 1000000,
  branchFactor: 1000
});

注意使用import Ranking = require('ranking')而不是import Ranking from 'ranking'。关于差异的完整讨论，我建议您参考这个github问题。

另外，我回答了一个非常相似的问题，您可能想要退房。
