Stack Overflow Asked by Pallab Ganguly on December 27, 2021
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 : '/',
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 = '/',
^^^^^^^^^^
SyntaxError: Invalid shorthand property initializer

I dont quite get what this means, and what I can do to resolve this.
use : instead of using = sign for fixing the error.

Change the = to : to fix the error.
var makeRequest = function(message) {<br>
var options = {<br>
host: 'localhost',<br>
port : 8080,<br>
path : '/',<br>
method: 'POST'<br>
}

Use : instead of =
see the example below that gives an error
app.post('/mews', (req, res) => {
if (isValidMew(req.body)) {
// insert into db
const mew = {
name = filter.clean(req.body.name.toString()),
content = filter.clean(req.body.content.toString()),
created: new Date()
};
That gives Syntex Error: invalid shorthand proprty initializer.
Then i replace = with : that's solve this error.
app.post('/mews', (req, res) => {
if (isValidMew(req.body)) {
// insert into db
const mew = {
name: filter.clean(req.body.name.toString()),
content: filter.clean(req.body.content.toString()),
created: new Date()
};

In options object you have used "=" sign to assign value to port but we have to use ":" to assign values to properties in object when using object literal to create an object i.e."{}" ,these curly brackets. Even when you use function expression or create an object inside object you have to use ":" sign. for e.g.:
var rishabh = {
class:"final year",
roll:123,
percent: function(marks1, marks2, marks3){
total = marks1 + marks2 + marks3;
this.percentage = total/3 }
};
john.percent(85,89,95);
console.log(rishabh.percentage);
here we have to use commas "," after each property. but you can use another style to create and initialize an object.
var john = new Object():
john.father = "raja"; //1st way to assign using dot operator
john["mother"] = "rani";// 2nd way to assign using brackets and key must be string

Because it's an object, the way to assign value to its properties is using :.
Change the = to : to fix the error.
var options = {
host: 'localhost',
port: 8080,
path: '/',
method: 'POST'
}
