How to Add a Param as Optional on GET Request with Axios

In the world of web development, making API requests often involves dealing with parameters, especially when using libraries like Axios. One common issue developers face is needing to add certain parameters to a request while ensuring that they remain optional. In this guide, we'll focus on how to make the similarText parameter optional in your GET request using Axios, all while keeping your code clean and linter-friendly.

Understanding the Problem

Imagine you have a function named getProducts that fetches product data from an API. This function makes use of Axios to send a GET request. You want to allow an optional similarText parameter to be passed along with the request if it is available. However, adding this parameter directly can lead to code that triggers linter warnings, which is less than ideal for maintaining a clean codebase.

Current Implementation

In the existing code, similarText is always included in the parameters sent with the request, regardless of whether it has a value or not. This approach is not optimal when the parameter is indeed optional.

The Solution: Using the Spread Operator

To create a cleaner and more flexible implementation, we can utilize the spread operator in JavaScript. This operator allows us to conditionally add properties to an object, which in our case will help us include the similarText parameter only when necessary.

Refactoring the Code

Here's how you could refactor the getProducts function to make the similarText parameter optional:

Key Changes Made

Conditional Parameter Addition:

Instead of always adding similarText, we now check if value exists. If it does, we include it; if not, we spread an empty object.

Cleaner Implementation:

This not only adheres to best programming practices but also keeps your code cleaner and more readable.

Conclusion

By following this method, you can make optional parameters in your Axios GET requests without run-ins with your linter, maintaining a priority on code quality and functionality. Utilizing the spread operator provides a succinct and effective means to achieve your goal.

For developers working with Axios and conditional parameters, adopting such practices can improve code maintainability and overall project robustness.

Now you can confidently add optional parameters to your GET requests — happy coding!
