Passing in Async functions to Node.js Express.js router

Question

This seems like a straightforward google, but I can\'t seem to find the answer...

Can you pass in ES7 async functions to the Express router?

Example:

<         


        

Answer 1

Use express-promise-router.

const express = require('express');
const Router = require('express-promise-router');
const router = new Router();   
const mysql = require('mysql2');

const pool = mysql.createPool({
  host: 'localhost',
  user: 'myusername',
  password: 'mypassword',
  database: 'mydb',
  waitForConnections: true,
  connectionLimit: 10,
  queueLimit: 0
}).promise();

router.get('/some_path', async function(req, res, next) {
  const [rows, ] = await pool.execute(
    'SELECT * ' +
    'FROM mytable ',
    []
  );

  res.json(rows);
});

module.exports = router;

(The above is an example of using mysql2's promise interface with express-promise-router.)
