The detailed tutorial outlines the process of building a voice recorder service using a Strapi backend and a React Native frontend. The guide begins with instructions on setting up a Strapi application, including database configuration and modeling application data with content types through the Strapi Admin dashboard. Users learn to enable GraphQL API and perform file uploads via GraphQL. The tutorial then shifts to creating a React Native mobile application using the Expo CLI, demonstrating how to connect it to the Strapi GraphQL API. Key functionalities such as user authentication, voice recording, and data storage are implemented with the help of various libraries, including Apollo Client for GraphQL operations and AsyncStorage for token management. The tutorial concludes with building navigation screens for the mobile application, allowing users to create accounts, log in, and manage their voice recordings. The entire process is documented with code snippets and explanations, providing a comprehensive guide for developers looking to integrate similar functionality into their applications.
