Making clean API requests to the Backend with URLSearchParams in React.

In the earlier days of crafting URLs in my React projects, I leaned on the trusty technique of String Interpolation for wrangling those pesky URL parameters. Sure, it got the job done, but deep down, it felt a bit off, like wearing mismatched socks – functional working, yet not quite right. The code lacked the finesse I yearned for, and as the project grew, the unease lingered. If you've ever sensed that discomfort when using String Interpolation for URL parameters, you're not alone. Let's explore a more fitting solution that not only does the job but does it with a touch of elegance.

Enter ---> a cleaner and more structured approach using URLSearchParams in React.

"URLSearchParams" is a built-in JavaScript object that allows you to work with the query string of a URL. It provides methods for appending, deleting, getting, and setting key-value pairs in the query string.

Here is how we can utilize URLSearchParams for clean API.

 const queryParams = new URLSearchParams();
 queryParams.append("limit", "10");
 queryParams.append("offset", offset);
 if (isActive) {
   queryParams.append("active", "true");

 const params = `?${queryParams.toString()}`;
 const url = `${api}${params}`;
Enter fullscreen mode Exit fullscreen mode

We create a new instance of URLSearchParams to manage our URL parameters. The append method adds parameters to the URLSearchParams instance. Here, we add "limit" with a static value of "10," "offset" with a dynamic value, and "active" conditionally. The if (isActive) statement ensures that the "active" parameter is appended only if the isActive variable is truthy. We construct the query string using queryParams.toString(). Finally, we combine the base API URL (api) with the constructed query string to form the complete URL.


  1. Structured Parameters: Each parameter is appended individually, enhancing readability.
  2. Conditional Appending: Conditions for appending parameters are clearer.
  3. Dynamic Values: Easily accommodates dynamic values.
  4. Automatic Encoding: Takes care of encoding special characters, reducing the risk of errors.

While both approaches achieve the same result, the URLSearchParams approach is cleaner, more readable, and easier to maintain, especially as our project complexity increases. If you have found a better way, feel free to share it in the COMMENTS. Do REACT and FOLLOW ME to hear more from me.
