Removing query parameter using node.js not working

I am having this code to remove a query parameter from a url, but it is not working. Can you have a look please?

const url = require('url')

const obj = url.parse('http://www.example.com/path?query1=val1&query2=val2', true)
delete obj.query.query2
const link = url.format(obj)
console.log(link) // I was expecting the removal of query2 but it didn't happen

It logged the same url as was passed above, why query2 is not removed? Thanks

You need to remove search node from object 

const obj = url.parse('http://www.example.com/path?query1=val1&query2=val2', true)
delete obj.query.query2
delete obj.search

const link = url.format(obj)
console.log(link)

This will return you url http://www.example.com/path?query1=val1

Even though you delete query2 from query object, query2 is still present in search field.

const url = require('url');

const obj = url.parse('http://www.example.com/path?query1=val1&query2=val2', true)
console.log(obj);
delete obj.query.query2
delete obj.search
console.log(obj);
const link = url.format(obj)
console.log(link)

const url = require("url")

const urlObj = url.parse('http://www.example.com/path?query1=val1&query2=val2', true)

delete urlObj.query.query2
delete urlObj.search

const newUrl = url.format(urlObj)

console.log(newUrl) // print >> http://www.example.com/path?query1=val1

If you look at through the source for url module (https://github.com/defunctzombie/node-url/blob/master/url.js). You can see that it will look at the search node first (line 413). Remove this as well, so that the query object is evaluated.

delete obj.search;
