nodejs - first argument must be a string or Buffer - when using response.write with http.request

Question

I\'m simply trying to create a node server that outputs the HTTP status of a given URL.

When I try to flush the response with res.write, I get the error: throw new T

Answer 1

response.statusCode is a number, e.g. response.statusCode === 200, not '200'. As the error message says, write expects a string or Buffer object, so you must convert it.

res.write(response.statusCode.toString());

You are also correct about your callback comment though. res.end(); should be inside the callback, just below your write calls.
