flowwatch-client (Python)

Python client for FlowWatch — connects to a running FlowWatch sidecar over HTTP.

Install

pip install flowwatch-client

Usage

Start the FlowWatch sidecar in your Node.js app:

import { createFlowwatch, startSidecar } from "@pranshulsoni/flowwatch"

const fw = await createFlowwatch({ ... })
startSidecar(fw, { port: 9400, token: process.env.SIDECAR_TOKEN })

Then use the Python client:

from flowwatch import FlowwatchClient

fw = FlowwatchClient(base_url="http://localhost:9400", token="your-token")

# Feature flag
enabled = fw.flag("new-checkout", context={"userId": "u_123", "plan": "pro"})

# Trigger a workflow
result = fw.trigger("send-welcome-email", input={"userId": "u_123"})

# Record a trace span
fw.trace_span(name="db.query", type="db", duration_ms=42)

# Capture an error
fw.capture_error(message="Something broke", source="api", name="ValueError")

# Health check
status = fw.health()  # {"status": "ok", "sidecar": "flowwatch"}

fw.close()

Use as a context manager:

with FlowwatchClient("http://localhost:9400", token="your-token") as fw:
    enabled = fw.flag("dark-mode")
