A better way to add URL params

Let's say you are building a filter component for a search page. To achieve this, you might use template strings to build you url params.

const urlParams = `?checkin=${filter.values.checkin}&checkout=${filter.values.checkout}`;

This might look ok but it can get a bit difficult to read when it gets more values.

An alternative way is to use query-string. It provides a stringify function that allows you to pass an object and it generates the url params for you.

import queryString from 'query-string';

const urlParams = queryString.stringify({ 
   checkin: filter.value.checkin,
   checkout: filter.value.checkout

The result is a way of generating your URL params without having to manually add &. It is also easier to read when you have to pass multiple values.

Hi there, interesting article, thanks for sharing!

Did you know that there is a native object to handle url queries in JavaScript (Browser)?

"use strict";

const urlSearchParams = new URLSearchParams();

urlSearchParams.append("color", "yellow");
urlSearchParams.append("form", "circle");
urlSearchParams.append("keywords", "young kids playground");

// color=yellow&form=circle&keyword=young+kids+playground

Hi Amin!

Yeah, based from caniuse, IE and other Chinese browsers do not support it.

So maybe it depends on your target audience if you'll use URLSearchParams
