Dev Utils Package

Overview

Dev Utils Package is a monorepo of 15 framework-agnostic Python packages designed as production-ready building blocks for applications. Rather than re-implementing infrastructure concerns for every new app, each package handles one concern — logging, caching, database access, error handling, job scheduling, agent scaffolding — and applications are assembled by combining only what they need. Packages compose cleanly via shared abstractions (BaseAppException, AbstractDatabase, AbstractCache) so they speak the same language when used together.

Key Features

• 15 standalone installable packages covering the full application infrastructure stack (logging, caching, DB, events, jobs, workflows, notifications, and more)
• Framework-agnostic — integrates with FastAPI, Streamlit, CLI (Typer), and microservice targets
• Optional inter-package integrations that activate automatically when sibling packages are installed, with no mandatory coupling
• LLM-aware caching, MCP-aware resource caching, and composable mixin-based agent base class for AI applications
• Uniform adapter layer (tool_interface_adapter) normalising REST APIs, CLIs, ML models, gRPC, and WebSockets into a single AbstractTool interface
• Pre-built wheels in Dependencies/ for offline installation; all packages support editable installs

Technical Decisions

Built entirely in Python 3.11+ with Pydantic v2 as the shared data-modeling layer across the ecosystem. Package boundaries are intentional — each concern is isolated, and optional integration bridges mean sibling packages can interoperate without creating hard dependencies. The LLM-facing packages (abstract_agent, cache_manager, tool_interface_adapter) use composable mixin patterns so callers can opt into capabilities (caching, observability, scheduling) without inheritance overhead. workflow_manager and ui_controller_base sit at the top of the dependency graph as the highest-level application shells.
