Invalid shorthand property initializer [closed]

I wrote the following code in JavaScript for a node project, but I ran into an error while testing a module. I’m not sure what the error means. Here’s my code:

var http = require('http');
// makes an http request
var makeRequest = function(message) {
 var options = {
  host: 'localhost',
  port = 8080,
  path : "https://stackoverflow.com/",
  method: 'POST'
 }
 // make request and execute function on recieveing response
 var request = http.request(options, function(response) {
  response.on('data', function(data) {
    console.log(data);
  });
 });
 request.write(message);
 request.end();
}
module.exports = makeRequest;

When I try to run this module, it throws the following error:

$ node make_request.js
/home/pallab/Desktop/make_request.js:8
    path="https://stackoverflow.com/",
    ^^^^^^^^^^

I dont quite get what this means, and what I can do to resolve this.
