Building React Native Apps Backed by AWS Lambda and Serverless Redis

A mobile application for managing a leaderboard is developed using React Native, the Serverless Framework, and Upstash Redis. The app allows users to view and update leaderboard scores through a backend supported by AWS Lambda functions written in Python. Upstash Redis is used for its efficient "Sorted Set" data type, which simplifies storing, querying, and updating scores. The Serverless Framework facilitates the deployment and management of serverless functions that handle HTTP requests for adding scores and retrieving the leaderboard. Users interact with the app through two main screens: one for submitting scores and another for viewing the leaderboard, both connected to the backend endpoints. The process includes setting up Upstash, configuring serverless functions, and integrating the app with the backend to ensure smooth data operations.
