replit-river 0.2.19

Replit river toolkit for Python

River

Machinery for compatibility with https://github.com/replit/river, the protocol behind the Workspace ↔ pid2 WebSocket (and in general, the protocol behind the Workspace ↔ * WebSocket).

Since the pid2 services are declared in TypeScript using TypeBox in the main repl-it-web repository, and it would be terrible for everyone involved to force folks to follow this paradigm of declaring their services, types, and interfaces in a foreign repository, any other River servers will use gRPC for their protocol definition and implementation. The @replit/river-codegen package can be used to compile the gRPC .proto files into a River-compatible TypeBox declaration that can be then packaged into an npm package that can be imported by the Workspace and consumed ergonomically.

This includes the necessary machinery to act as a client or server for River:

• As a River server, create a WebSocket server and the gRPC -> Python River codegen (similar to the protoc flow that generates the Python bindings).
• As a River client, create a WebSocket client and the JSON Schema -> Python River codegen. python -m river.codegen client --output pkgs/river/river/schema.py --client-name Pid2Client pkgs/river/schema.json
• If we need to create the client-side of a Python gRPC River server, we also need to generate the JSON schema from the .proto file, with this command: python -m river.codegen server-schema --output pkgs/river/river/schema.py pkgs/river/tests/client/proto/test.proto && cat ./test_schema.json

Publishing

Make sure you have pypi token setup, easiest way is to set env var POETRY_PYPI_TOKEN_PYPI.

• update version either manually or via poetry version
• poetry build
• poetry publish
