Automatic include file resolved via require

[theKashey]

Current behaviour

https://zeit.co/docs/runtimes#advanced-usage/technical-details/including-additional-files

const file = readFileSync(join(__dirname, 'config', 'ci.yml'), 'utf8');
// The use of __dirname is necessary to read a file relative to the current file.

Better behaviour

use require.resolve

const file = readFileSync(require.resolve('./config/ci.yml'), 'utf8');

What is not good about it

It already works at now dev, but not in prod.

Thanks for the suggestion!

require.resolve should be fine to use here and should be supported - if not that would a bug in node-file-trace.

Confirmed, this is working as expected

Yep. It was a mistake of mine - I was trying to read something from public directory, which does not exist for functions.
