Make .well-known directory visible in Express 4

Question

This took me a while to figure out, so I figure I'd leave some instructions on how I got it done in case someone else runs into the same problems.

I needed to allow directory access to the .well-known directory in Express to be able to use certbot to generate SSL certificates.

Answer 1

Install the serve-index package from npm

npm install serve-index

Import it

var serveIndex = require('serve-index');

Then declare the middleware

app.use('/.well-known', express.static('.well-known'), serveIndex('.well-known'));
