HEAD route is not automatically added for GET routes

[onebytegone]

For all GET routes, express will add support for HEAD requests automatically if a HEAD route is not already defined. lambda-express does not do this. At this time you must manually add the HEAD route.

Express docs: https://expressjs.com/en/api.html#router.METHOD

The router.get() function is automatically called for the HTTP HEAD method in addition to the GET method if router.head() was not called for the path before router.get().

Express sample:

$ cat index.js
const express = require('express')
const app = express()
const port = 3000

app.get('/', (req, res) => res.send('Hello World!'))

app.listen(port, () => console.log(`Example app listening at http://localhost:${port}`))

$ curl --head http://localhost:3000
HTTP/1.1 200 OK
