def is an abbreviation for define, so it can be read as define js.

Defjs is a library that helps you define and initiate requests, aiming to make it easier for you to define requests without worrying about the details.

• Supports multiple request methods such as Fetch, XMLHttpRequest, custom, etc.
• Functional API.
• 🚧 Supports streaming. (WIP)
• Supports JS/TS with complete type.
• Supports any JS runtime.
• Supports Interceptors.
• Supports ESM
• 🚧 Supports Mini Programs. (WIP)
