Uploading files from React Native or Expo

Indy Khare's guide provides a detailed approach to uploading files from React Native or Expo applications to Convex remote servers, using a mobile app example that records voice notes. The process involves setting up Convex mutations for generating upload URLs and storing app-specific metadata. It demonstrates step-by-step how to upload a file by obtaining a URI, fetching the file, handling errors, and finally sending the file to Convex, with a focus on using appropriate MIME types for audio recordings. Once uploaded, the file's storage ID is used to save custom metadata, ensuring the data is appropriately stored and accessible. The guide underscores the capabilities of Convex as a backend platform for full-stack AI projects, highlighting its integration of cloud functions, databases, file storage, and more to support scalable applications.
