How to Fetch Data and Populate a React-Native Table

When developing applications with React Native, you may encounter the need to dynamically display data fetched from an API. For new developers, this could seem daunting. In this post, we will walk through the process of fetching data and displaying it in a table using the react-native-table-component library.

Understanding the Problem

As a beginner in React Native, it's common to feel overwhelmed by how to integrate API data into your app. You might want to load user information from an API and display it in a clean and organized table format. Our goal is to create a simple interface that allows users to click a button and see their data in a table view.

Setting Up the Table

We will leverage the react-native-table-component to create our table layout. Here’s how to proceed:

1. Initializing the Component

Begin by creating a new React Native component that initializes the table structure. This includes defining the table headers and the properties that dictate column widths:

2. Fetching Data from the API

Next, we will add a function to fetch data from a provided API endpoint. This will be triggered when the user presses a button. Here’s the code for that function:

This code fetches user data and updates the component's state with the new data, which will be reflected in the table.

3. Rendering the Table

Now we turn our attention to rendering the table in the render method. We will use the fetched data to create row entries in the table layout:

4. Putting It All Together

Here's the complete component code that combines all the above sections:

Conclusion

By following these steps, you now have a functional React Native table that fetches and displays data from an API! This implementation not only simplifies the process but also provides a clear and structured approach to handling data in your app.
