Have you ever wondered how to create your own chat application? With React Native, you can build a real-time chat app that allows users to communicate instantly. This article will guide you through the process, providing a step-by-step tutorial based on a YouTube video tutorial. By the end of this guide, you’ll have a functioning chat application and a solid understanding of React Native.

Setting Up the Chat Interface

The first step in creating a chat application is setting up the chat interface. This includes creating a message box for users to type their messages and a display area where these messages will appear. In React Native, you can create these elements using components, which are reusable pieces of code that render some output.

In our chat app, each message will be displayed with the user’s name. To differentiate between the current user and other users, we will use a unique ID for each user. This ID will be used to conditionally render the user name and message. If the message is from the current user, it will be displayed differently than messages from other users.

Styling the Chat Interface

Once the basic elements of the chat interface are set up, you can start styling it. React Native provides a style property that allows you to add CSS styles to your components. You can use this property to change the color of the messages based on the user, position the messages on the screen, and much more.

For our chat app, we will use different colors for different users. This will make it easier for users to distinguish between their own messages and those of others. We will also position the messages so that they appear in a conversational format.

Displaying Messages in the Correct Order

When displaying messages in a chat app, it’s important to ensure that they appear in the correct order. In most chat apps, new messages appear at the bottom of the screen, and older messages are pushed up. To achieve this in React Native, you can use the ‘inverted’ property of the FlatList component.

The FlatList component is a simple wrapper for a more complex list view, and it’s perfect for displaying a long list of items. By setting the ‘inverted’ property to true, you can make the FlatList display items from bottom to top, which is exactly what we need for our chat app.

Adding an Image Background

To make our chat app more visually appealing, we can add an image background. React Native provides the ImageBackground component for this purpose. This component displays an image as the background of its children, allowing you to create a visually rich interface.

For our chat app, we will choose an image that complements the color scheme of our messages. The image will be displayed behind the messages, adding depth and visual interest to the chat interface.


Building a real-time chat app in React Native is a rewarding project that can help you learn more about app development and React Native. By following this guide, you can create a functional chat app with a unique ID for each user, a styled chat interface, messages displayed in the correct order, and an image background. So why wait?
