fnforge

Note: This project is a Work in Progress (WIP).

fnforge is a new, universal standard for functions. It aims to provide a consistent way to define, discover, and execute functions across different platforms and programming languages.

The Problem

Traditionally, functions are exposed and consumed in various ways:

• CLI: Arguments and flags, often string-based and parsed manually.
• REST: JSON payloads, headers, and query parameters, with varied schemas.
• Programming Languages: Language-specific types, interfaces, and calling conventions.

Each of these methods defines inputs and outputs differently, leading to fragmentation and the need for constant translation between formats.

The Standard

fnforge introduces a unified approach. In this standard, every function must explicitly define:

• The type of input (In)
• The type of output (Out)

The format also specifies bidirectional communication, allowing for interactive or streaming exchanges between the caller and the function.

Notably, fnforge focuses on the communication contract and data structures without necessarily specifying the transport data layer. This allows the standard to be implemented over various protocols (like WebSockets, gRPC, HTTP/3, or even local pipes) while maintaining a consistent functional interface.
