I'm currently working on an Express project that utilizes TypeScript. I have set up controllers, routers, and implemented a method that encapsulates my controller logic within an error handler.
While working in my router.ts file, I encountered an error with the post method:
The call does not match any overload.
The final overload triggered this error.
The argument type '(req: Request, res: Response, next: NextFunction) => void' is not compatible with the parameter type 'Application<Record<string, any>>'.
Apologies if this question seems basic, but as someone new to TypeScript and these kind of type errors, I am struggling to identify the solution.
router.ts
import express from "express";
import { signup } from "../controller/controller.ts";
const authRouter = express.Router();
authRouter.post("/signup", signup);
controller.ts
import { NextFunction, Request ,Response } from "express";
import asyncHandler from "../utils/asyncHandler";
const signup = asyncHandler((req:Request, res:Response, next: NextFunction) => {
res.status(200).json({ message: "signup" });
});
export { signup };
asyncHandler.ts
import { Request, Response, NextFunction } from "express"
const asyncHandler = (fn:any) => (req: Request, res: Response, next: NextFunction) => {
Promise.resolve(fn(req, res, next)).catch(next)
}
export default asyncHandler;
