javascript - js工具库需要index.d.ts 实现.?

Question

写了一个js 工具库，但是 index.d.ts 这块无法得到满意的实现，需要帮助。具体看下方issues
single-promises issues

可在issues 里看到。

Answer 1

给你稍微改了下

declare module 'single-promises' {  export interface SingleOptions {      cache?: number;  }  type FunctionType = (...args: any) => any;  export interface SinglePromiseHandle<T extends FunctionType> {      (...args: Parameters<T>): ReturnType<T> extends Promise<any> ? ReturnType<T> : Promise<ReturnType<T>>;      clear(): void;      update(newOpt?: SingleOptions): void;  }  export function singlePromise<T extends FunctionType>(fn: T, opt?: SingleOptions): SinglePromiseHandle<T>;  export const version: string;}

Answer 2

interface SingleOptions {    cache?: number}interface SingleFunc<P extends unknown[], T> {    (...args: P): T extends Promise<unknown> ? T : Promise<T>    update(opt?: SingleOptions): void    clear(): void}export function singlePromise<P extends unknown[], T>(    fn: (...args: P) => T,    opt?: SingleOptions): SingleFunc<P, T>
