Is there Node.js ready-to-use tool (installed with npm), that would help me expose folder content as file server over HTTP.
Example, if I have
connect could be what you're looking for.
Installed easily with:
npm install connect
Then the most basic static file server could be written as:
var connect = require('connect'),
directory = '/path/to/Folder';
connect()
.use(connect.static(directory))
.listen(80);
console.log('Listening on port 80.');
