`trpc-core`

Toolkit for implementing tRPC servers in python

trpc-core is currently in prototype stage. You are welcome to play with the code or drop feedback in issues, just don't expect anything usable or functional yet.

Example tRPC API with Flask:

import json

import trpc
from flask import Flask, jsonify, request


class Router(trpc.Router):
    @trpc.query(name="helloWorld")
    def hello_world(context) -> str:
        return "Hello world"

    @trpc.mutation(name="sum")
    def sum_items(context, *, a: int, b: int) -> int:
        return a + b


backend = trpc.Backend(Router)


app = Flask(__name__)


def batch_request():
    return request.args.get("batch") == "1"


def create_response(result: trcp.Result):
    return jsonify(result.data), result.status_code


@app.route("/trpc/<path:path>", methods=["GET"])
def trpc_query(path):
    if request.args.get("input"):
        input_data = json.loads(request.args["input"])
    else:
        input_data = None

    result = backend.query(
        path,
        batch=batch_request(),
        params=input_data,
        context=request,
    )
    return create_response(result)


@app.route("/trpc/<path:path>", methods=["POST"])
def trpc_mutation(path):
    result = backend.mutation(
        path,
        batch=batch_request(),
        params=request.get_json(),
        context=request,
    )
    return create_response(result)
