ModApp

Goal of the ModApp project is to find an optimal way of interprocess and interapplication language-agnostic communication and to provide reference implementation.

Principles

TODO: detail explanations

• language-agnostic
• transport-agnostic
• encoding-agnostic
• contract-oriented (not required, but very recommended)
• don't force use ModApp on both ends, keep protocol open

Existing solutions and comparison

• GRPC

• HTTP + WebSockets

• TRPC

Status

The project is used in production by author, but it isn't ready for production usage by other developers because of:

• lack of tests
• lack of documentation

Existing solutions where ModApp is used to give a bit of understanding what technology already can:

• Python backend + Electron frontend (commercial)
• Python backend + Qt frontend (commercial)

Currently supported technologies:

• Python server:

  • Transports: grpc, web_socketify(http+websocket)
  • Converters: json, protobuf
  • Models: pydantic, dataclass

• JavaScript client: http+websocket and json/protobuf

Python ModApp framework

• prefer code generation over magic and runtime overhead (at least in production version)
