Fullstack Serverless app with Flutter, Serverless Framework and Upstash(REDIS) - PART 1

The text outlines the process of building a serverless mobile application using Flutter, Serverless Framework, Upstash, and Redis, focusing on creating a CRUD API for managing users and posts. Upstash serves as a serverless database for Redis, offering a pay-per-request model and global low-latency access. The guide introduces Redis as an in-memory data structure store and explains how to use various Redis data types and commands such as SET, INCR, HMSET, and LPUSH to manage user and post data. It details the creation of a serverless project and explains the API endpoints for user creation, updating, retrieval, and listing, as well as for post creation, retrieval, and user reactions. The document emphasizes best practices like using pipelines for batch operations and understanding access patterns to optimize data retrieval. Additionally, it touches on the use of sorted sets for managing post reactions and provides the complete source code for the project, encouraging further exploration and development.
