express-async-catch

Simple wrapper for Express route handlers, which propagates errors to the centralized error handler.

Install

npm install express-async-catch

Usage

1. Import the wrapper function

   EcmaScript Modules (ESM)

   import { asyncCatch } from 'express-async-catch';

   CommonJS Modules (CJS):

   const asyncCatch = require('express-async-catch');

2. Wrap your route handlers:

   app.get(
     '/api/product/list',
     asyncCatch(async (req, res, next) => {
       // ...
     }),
   );

Notes

• This wrapper will catch thrown Errors.
• This wrapper will catch promise rejections, when the await keyword is used.
• It cannot catch errors that generated by un-awaited promises.
• It cannot catch errors that are handled via callbacks.
• It cannot be used to wrap the error handler (signature err, req, res, next) because it expects the wrapped route handler to have the signature (req, res) or (req, res, next).
