awrap - async function wrapper for express.js

express.js can take async function as middleware or handler function, however, it cannot handle the error correctly. When error happens, the request will never complete.

awrap turns async function into a normal function that express.js can accept.

Installation

$ npm install awrap

Usage

Just wrap the async function with awrap and pass into express:

app.get('/', awrap(async (req, res) => {
  console.log('processing /')
  await sleep(200)
  res.send('Hello async/await!')
}))

Example

This is an example server implementation.

To run it:

$ npm install
$ npm run example
