How to Conditionally Render Badges in ReactJS with map()

When developing applications in ReactJS, it's common to pull data from an API and display it dynamically. One common requirement might involve changing the appearance of UI components based on specific record values. For example, you may want to display different colored badges based on the status of a record, such as "Aprobado" (Approved) or "Rechazado" (Rejected). However, many developers encounter issues when trying to implement these conditions correctly. Let's explore the solution to this problem step-by-step.

The Problem

In your current implementation, you're attempting to use if statements to conditionally render badge components inside the map() function. However, these conditions are enclosed in an arrow function, which is not being called. This leads to your code not rendering any badges when it's executed.

Example Code Snippet

This structure creates a function that never gets executed, leading to no output.

The Solution

To resolve this issue, we recommend using a ternary operator directly within the badge's bg prop. This approach allows you to check the status and render the badge color accordingly without encapsulating the logic in a function that isn't invoked.

Using the Ternary Operator

Here’s how you can effectively use a ternary operator for your badges:

This single line of code does the following:

Checks if estatusfirma_tienda is "Aprobado". If true, it sets the badge color to success (green).

If not, it checks if estatusfirma_tienda is "Rechazado". If true, it sets the badge color to danger (red).

If neither condition is met, it defaults to warning (yellow or orange).

Example Implementation

Here’s how your full component might look with this implementation:

Conclusion

By utilizing the ternary operator within your JSX, you can cleanly and efficiently conditionally render components based on the values in your API data. This method not only resolves the rendering issues you're experiencing but also keeps your code concise and readable. Happy coding in ReactJS!
