How to Email SQLite Data in React Native Apps

In today’s mobile app development landscape, many developers find themselves needing to share data directly from their applications. If you are working with a React Native app and have integrated SQLite for local data storage, you may want to send that data via email. This article will guide you through the process of emailing data from SQLite, ensuring that the information is neatly formatted in the email body.

Understanding the Problem

You have a React Native app that pulls data from an SQLite database, but you need to send this information through email. The main challenge is to ensure that the data extracted from SQLite can be successfully integrated into the email body, and notably, it appears you are experiencing an issue where the data is not being returned as expected.

Step-by-Step Guide to Emailing SQLite Data

1. Declare State for the Data

First, you'll need to create a state to hold the data extracted from your SQLite database. Utilize the useState hook to set this up within your component.

3. Email the Data

Now that you've successfully retrieved and stored your SQLite data, you can use it in the email body. Construct the email body using the state data with JSON.stringify(), which helps format the data into a JSON string.

Here's how you can integrate this into your sendEmail function when a button is pressed:

With these processes in place, you can seamlessly share data stored within your app with external recipients.
