I try to make a exercise of nodeschool.io but I cannot make it work.
I have this :
var http = require ('http');
var fs = require('fs')
http.createServer(function(req, res) {
var filename = __dirname+ process.argv[3]
var readStream = fs.createReadStream(filename);
readStream.on('open', function () {
readStream.pipe(res);
});
readStream.on('error', function(err) {
res.end(err);
});
}).listen(process.argv[2]);
then I see this error
http.js:851
throw new TypeError('first argument must be a string or Buffer');
^
