Introduction

When dealing with APIs in React, you often encounter complex data structures that require careful navigation. In this guide, we will address a common problem faced by developers: extracting specific price values from a nested array obtained from an API response.

To illustrate this, we will walk through a scenario where an array of ticket prices is fetched from an API, and we need to retrieve four key attributes for future calculations:

advancedCommission

Box Seats - Ground Floor's adultPrice

ODC's adultPrice

ODC's childPrice

Let’s dive right into the solution.

Setting up the API Request

We start by making a GET request to an API endpoint that returns ticket prices. In our example, the data looks like this:

Extracting Price Values

Now that we have the ticket prices, the next step is to extract the specific values we need. This can be achieved by filtering the priceList array based on the seatType.

The Filtering Process

Advanced Commission:

Directly accessed from the ticket prices.

Box Seats - Ground Floor's Adult Price:

Filter the priceList for the seatType that includes "Box Seats - Ground Floor".

ODC Prices:

Filter the priceList for the seatType that includes "ODC".

Code Snippet for Extracting Values

In the processSeatPriceData function, we can implement the extraction as follows:

Utilizing the Extracted Values

Once the component state is populated with the extracted values, you can easily access these properties in other functions. Here’s how:

Conclusion

In summary, extracting specific price values from a nested array in an API response is quite straightforward. By adequately filtering the data, you can acquire the desired attributes and maintain them in your component's state for future calculations. This method ensures your application remains organized and efficient when handling API data.

By following the steps outlined in this guide, you should now have a clearer understanding of how to approach similar challenges in your projects. Happy coding!
