To build a chat app for mobile devices using React Native. The app will provide users with a chat interface and options to share images and their location.
More and more people use their phones for daily tasks, such as shopping, creating to-do lists, communicating with friends, scheduling meetings, and more. That's why many companies offer native mobile versions of their web apps, or even skip creating a web app entirely.
In the past, building high-quality mobile apps required a lot of time and money because writing apps for different platforms like iOS and Android required specialized programmers who could build and maintain multiple codebases.
Over time, however, new technologies emerged that made it easier for companies to build and maintain mobile applications using familiar syntax. One of these technologies is React Native, a framework for building Android and iOS apps that only requires one codebase. For this Achievement’s project, you’ll use React Native, Expo, and Google Firestore Database to build a chat app that you can add to your portfolio and demonstrate your knowledge of JavaScript mobile development.
- As a new user, I want to be able to easily enter a chat room so I can quickly start talking to my friends and family.
- As a user, I want to be able to send messages to my friends and family members to exchange the latest news.
- As a user, I want to send images to my friends to show them what I’m currently doing.
