Kstlib Logo

Config-driven Python toolkit for resilient applications

CI Documentation PyPI Python License

kstlib is a personal Python toolkit built over 7 years of learning and experimentation.

It started as a way to explore Python best practices, evolved into utilities for personal automation, and now serves as the foundation for study projects in algorithmic trading and market analysis.

The focus has always been on building resilient, secure, and performant systems.

Note: Everything works via Python, but since kstlib is heavily config-driven, the Examples Gallery showcases a YAML-first approach.

Core Modules

Module Purpose
config Cascading config files, includes, SOPS encryption, Box access
secrets Multi-provider resolver (env, keyring, SOPS, KMS) with guardrails
logging Rich console, rotating files, TRACE level, structlog integration
auth OIDC/OAuth2 with PKCE, token storage, auto-refresh
mail Jinja templates, transports (SMTP, Gmail API, Resend, AWS SES)
alerts Multi-channel (Slack, Email), throttling, severity levels
websocket Resilient connections, auto-reconnect, heartbeat, watchdog
rapi Config-driven REST client with HMAC signing
pipeline Declarative sequential workflows (shell/python/callable steps), error policies, conditional execution
monitoring Collectors + Jinja rendering + delivery (file, mail)
resilience Circuit breaker, rate limiter, graceful shutdown
ops Session manager (tmux), containers (Docker/Podman)
helpers TimeTrigger, formatting, secure delete, validators
