I've read posts all over concerning this and I know it must be something silly, but I can't figure out why the following code is throwing "TypeError: listener must be a function"
Assume options
var server = https.createServer(options, function(request,response){
if (request.url==='/') request.url='/home/altronic/Opti-Cal/web/arimonitor.htm';
console.log("Request: " + request.url);
fs.readFile("public"+request.url,function(error,data){
if (error) {
response.writeHead(404, {"Content-type":"text/plain"});
response.end ("Sorry the page you requested was not found.");
} else {
response.writeHead(200,{"Content-type":mime.lookup('public'+request.url)});
response.end (data);
}
})
}).listen(port);
Console output:
events.js:130
throw TypeError('listener must be a function');
^

Can anyone help me figure this out?
Where do you assign https
? It looks like you’re probably requiring http
, not https
. http.createServer
doesn’t accept options like https.createServer
.
You may hit this error when using a node version < 9.6
See the docs and history. I was very confused that the docs said I could use an options object on http.createServer and got this error until I realized I hadn't updated node in a while.
