Skybridge: TypeScript Framework for ChatGPT Apps (github.com)

Skybridge has launched a new fullstack TypeScript framework designed for building ChatGPT applications, enhancing the development experience by introducing features like zero configuration, full type safety, and React-powered components. With Skybridge, developers can create rich, interactive user interfaces directly within conversations, addressing shortcomings found in the raw ChatGPT SDK that previously lacked hooks, dev tools, and hot module replacement (HMR). The framework enables a seamless development environment with live reload capabilities, local dev tools, and automatic type inference for improved productivity. Significantly, Skybridge brings a structured and efficient approach to ChatGPT app development, allowing for dual surface synchronization between UI state and LLM awareness using the data-llm feature. It incorporates familiar React Query-style hooks for state management, making it easier for developers to manage interactions and display dynamic content. The framework is fully compatible with the existing MCP SDK and supports various package managers, ensuring broad accessibility and integration potential for existing projects. Overall, Skybridge aims to streamline the development workflow while enhancing the capabilities of ChatGPT applications in real-time interactions.
