Very simple route module for validating with Let's Encrypt
Provide the follow environment variables - LETSENCRYPT_CHALLENGE
and LETSENCRYPT_RESPONSE
.
You can get these values by running certbot in manual mode
sudo certbot certonly --manual
After following the wizard you should get to a point where it outputs this in the console:
Make sure your web server displays the following content at
http://app.foo.bar/.well-known/acme-challenge/<LETSENCRYPT_CHALLENGE> before continuing:
<LETSENCRYPT_RESPONSE>
Update your server with these variables. Not you can let the wizard validate against your server and you will get your certificate!
const letsencrypt = require('express-letsencrypt-simple');
...
app.use('/.well-known', letsencrypt);
