Config-driven Python toolkit for resilient applications
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 |
| 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 |
