Question

现在我在自定义的.d.ts文件中有这个：

.replaceAll("[\\([0-9]\\%)]","");

我像这样引用该文件：

import { Request, Response, NextFunction } from 'express';
export type MiddleWareFn = (req: Request, res: Response, next: NextFunction) => void;

但是我想知道Express是否已经为中间件功能打字？

Answer 1

是。您还需要导入RequestHandler。检查定义here

import { RequestHandler } from 'express';

Answer 2

这是我的处理方式：

import type { RequestHandler } from "express";

export const myMiddleware: RequestHandler = (req, res, next) => {
  // HANDLE REQUEST
  // RESPOND OR CALL NEXT()
};

对于Express中间件函数，@ types / express中是否有类型
