Components for your Backend

Convex Components provide a way to incorporate off-the-shelf backend features into applications, offering a powerful abstraction that encapsulates both state and behavior while maintaining a clean interface. These components, similar to frontend components, can persist state across sessions and users, and react to external inputs such as webhooks. They are designed to store data through various methods, including database tables with schema validation, file storage, and durable functions, with transactional guarantees that ensure data consistency. Convex Components run in isolated environments, preventing unauthorized data access and system behavior alterations, while also supporting local reasoning about data changes through explicit APIs. The article details the process of integrating components like aggregates for leaderboards, action caches for efficient data retrieval, rate limiters to control user actions, and migration managers to handle data modifications, highlighting the ease of configuration and installation. By combining the benefits of service-oriented and monolith architectures, Convex Components simplify backend development, promoting scalability and maintainability without sacrificing the ability to modify or replace components as needed.
