isA Common

Shared async Python client library for the isA platform.

Overview

isa-common provides async Python clients for interacting with isA Cloud infrastructure services. All clients use async with context managers and share a common base class (AsyncBaseClient).

Infrastructure Clients (require running services)

Local-Mode Clients (no external services needed)

Drop-in alternatives for desktop/offline use. Same API surface, backed by local storage:

When to use local clients: Use local-mode clients when running on desktop/ICP without cloud infrastructure, for development/testing without Docker, or when you need offline-capable storage.

Installation

pip install isa-common

Quick Start

from isa_common import AsyncRedisClient

async with AsyncRedisClient(host="localhost", port=6379, user_id="my-user") as client:
    health = await client.health_check()
    await client.set("key", "value")
    value = await client.get("key")

Using Local-Mode Clients

from isa_common import AsyncSQLiteClient, AsyncLocalStorageClient

# SQLite instead of PostgreSQL
async with AsyncSQLiteClient(database="app.db", user_id="my-user") as db:
    await db.query("SELECT * FROM users")

# Local filesystem instead of MinIO
async with AsyncLocalStorageClient(base_path="./storage", user_id="my-user") as storage:
    await storage.put_object("my-bucket", "file.txt", b"contents")

Development

Run tests (requires services or use local clients):

# Run individual service tests
python tests/redis/test_async_redis.py
python tests/duck/test_async_duckdb.py

# Run all tests via Makefile
make test

Contract Coverage

See tests/contract_coverage.md for the mapping between CDD contract IDs (BR/EC/ER) and test functions.
