Aspida

Aspida is a TypeScript-friendly HTTP client wrapper designed for both browser and Node.js environments. It streamlines API client generation by enabling developers to define API endpoint types through a convention-over-configuration approach, leveraging a directory structure and `DefineMethods` type aliases. This approach significantly enhances type safety for API interactions at compile time, eliminating the need for manual client creation. Aspida supports integration with popular HTTP clients like Axios, Fetch, and Node-Fetch via official adapter packages. The current stable version is 1.14.0, and the project demonstrates an active release cadence with frequent updates. Its key differentiators include robust type inference for paths, query parameters, headers, request bodies, and responses, comprehensive support for `FormData` and `URLSearchParams`, and a unique workflow that generates a fully type-safe client based on a filesystem-defined API structure.
