In a TypeScript file:

import allowMethods from "express-allow-methods";

In a JavaScript (CommonJS) file:

const allowMethods = require("express-allow-methods").default;

Usage

import express from "express";
import allowMethods from "express-allow-methods";

const app = express();

		// GET /
	})
	.post((req, res) => {
		// POST /
