How to Merge Multiple API Responses in Vue.js with Axios

When working with Vue.js, one common problem developers face is needing to merge data from multiple API calls into a single object. This is particularly challenging when you want to avoid unnecessary app refreshes to fetch related data. In this guide, we'll tackle the problem of joining three different responses from your API calls to create a cohesive data structure with just a single call.

Understanding the Problem

In this scenario, we have three separate API calls, each retrieving different pieces of data:

Cars Information (carsIn) - which includes details like id, username, useraddress, userphone, and plate.

Position Used (PositionUsed) - containing id_pos, id_car, and enterdate.

Position - which includes id_pos and name.

The goal is to merge these responses into a single data set that combines relevant information from all three, specifically including the properties: username, useraddress, userphone, plate, enterdate, and name.

A Standard Approach

Initially, the method attempted was prone to issues, as it required multiple refreshes of state. Instead, we can enhance our data fetching approach using Promise.all(), which allows us to handle multiple promises concurrently.

Updated Function with Promise.all

Here's an improved solution that ensures we fetch all the necessary data at once without the need for multiple refreshes:

Merging the Data

After fetching all the required data, the next step is to merge it effectively. Here's how to do that in a structured way:

Implementation of the Merge

Merge carsIn with PositionUsed: We will link each car with its corresponding position.

Merge the previous result with positions: Finally, connect the resultant array with the position names.

Here's how to implement this merging process:

Final Thoughts

By utilizing Promise.all() in combination with better structuring your data merging processes, you can effectively manage multiple API responses in Vue.js without the hassle of needing to refresh multiple times. This method not only enhances performance but also leads to cleaner and more maintainable code.

Now, you can easily get the merged data you need without unnecessary lags or complicated refresh mechanisms!
