How to Upload Image to Firebase in React Native

In today's digital world, allowing users to personalize their profiles by uploading images has become a common practice in mobile applications. If you are building a React Native application and want to let users upload their profile images to Firebase, you are in the right place. This blog will guide you through the step-by-step process of implementing this feature, ensuring that it is both efficient and user-friendly.

The Problem at Hand

We want to create a function where users can upload their own profile images. The main requirements are:

Users should be able to navigate to an image upload page and change their profile image.

The uploaded images should be securely stored in Firebase Storage under the user's unique ID (UID) for easy retrieval and management.

When users access their profile page, they should only see their previously uploaded images.

The program should allow users to upload images picked from their device.

How to Implement Image Upload in Firebase

To achieve the desired functionality, we’ll break down the solution into several clear steps. We'll utilize expo-image-picker to allow users to select images from their device and Firebase for storage.

Step 1: Setting Up Permissions

First, we need to ensure that our application has permission to access the user's device’s camera roll to pick images. This can be done using the following code in your component:

Step 3: Uploading the Image to Firebase

To upload the image, we’ll convert it into base64 format and then save it to Firebase Storage. Here’s a sample function for that:
