json-from-promise

Small Express connect-middlewere that sends json-response from your promise and errors with next.

Examples

CommonJS

const jsonFromPromise = require('json-from-promise').jsonFromPromise
app.get('/ping/:id', jsonFromPromise(function(req) {
  const id = req.params.id
  return Promise.resolve({
    pong: id
  })  

ES6

import { jsonFromPromise } from 'json-from-promise'
app.get('/ping/:id', jsonFromPromise(req => Promise.resolve({
  pong: req.params.id
})  

Note that you should (always) have a error-handler at the end of your application. If you don't you will get a unhandle promise rejection.
