express-async-handler

Simple middleware for handling exceptions inside of async express routes and passing them to your express error handlers.

Installation:

npm install --save express-async-handler

or

yarn add express-async-handler

Usage:

const asyncHandler = require('express-async-handler')

express.get('/', asyncHandler(async (req, res, next) => {
	const bar = await foo.findAll();
	res.send(bar)
}))

Without express-async-handler

express.get('/',(req, res, next) => {
    foo.findAll()
    .then ( bar => {
       res.send(bar)
     } )
    .catch(next); // error passed on to the error handling route
})

Import in Typescript:

import asyncHandler from "express-async-handler"

express-promise-router

express-promise-router is a drop-in replacement for Express's Router that allows you to use promises (including async/await) in your route handlers. It automatically handles rejected promises and passes errors to the next middleware. This package is more comprehensive as it replaces the entire Router, whereas express-async-handler is a middleware function.
