Solving the Network Error in Axios with React Native: A Guide for Developers

As a developer, encountering network errors while trying to connect your React Native application to a Django backend can be frustrating. In this guide, we will explore a common issue faced when making API requests using Axios and how to resolve it effectively.

The Problem: A Network Error with Axios

When you're developing a React Native application and try to fetch data from your Django backend using Axios, you might come across a network error. The error will typically look something like this:

[[See Video to Reveal this Text or Code Snippet]]

This error indicates that the React Native app is unable to reach the backend server located at http://127.0.0.1:8000/drugs/patients/. One critical point to keep in mind is the environment in which you're running your React Native application.

Why Is This Happening?

Localhost Reference: When you're using the emulator, 127.0.0.1 (localhost) refers to the emulator itself, not your development machine. Therefore, it cannot reach your Django server running on your local system.

Different Ports: Your React Native application and Django server often listen on different ports, leading to cross-origin issues if not properly configured.

Solution: Use the Correct IP Address

To fix the issue, you need to replace 127.0.0.1 with the special IP address that allows your Android emulator to communicate with your host machine.

Steps to Fix the Network Error

Identify the Correct IP Address:

If you're using the Android Virtual Device (AVD), the proper address to use is 10.0.2.2. This address serves as a bridge to your host machine's localhost.

Update Axios Request:
Change your Axios GET request from:

to:

Testing with an Emulator: Once you make this change, re-run your application on the emulator. Your call to the Django server should now work as expected, allowing you to retrieve the necessary data.

Summary

If you're getting network errors while trying to connect your React Native app to a Django backend, remember to use 10.0.2.2 when you're working with an Android emulator. This small tweak can resolve the problem and ensure your network requests go through without issues.

Your development journey should be smooth, and with these simple adjustments, your React Native application will be able to communicate effectively with your Django backend!

If you're still facing issues, ensure that your server is running and accessible and check for any additional configurations in network settings that might be affecting connectivity.

Happy coding!
