🚀 TamilPY v0.1.9 Released — A Schema-Driven FastAPI Platform Gets Even More Powerful

#fastapi #python #opensource #webdev


We're excited to announce TamilPY v0.1.9, our biggest release yet! 🎉

This release transforms TamilPY into a more complete schema-driven FastAPI platform, introducing powerful runtime capabilities, a fluent Query Builder, background jobs, scheduling, caching, application lifecycle management, and a significantly improved developer experience.

Whether you're building APIs, internal tools, or enterprise applications, v0.1.9 helps you build faster while writing less boilerplate.

📚 Documentation

Our documentation has also received a major upgrade with a professional GitHub Pages site featuring clickable feature cards, responsive layouts, and detailed study guides.

✨ What's New in v0.1.9

🔍 Fluent Query Builder

Introducing tpy.query, a schema-driven query builder designed for clean, readable, and secure database queries.

Highlights

  • Parameterized queries
  • SQLite support
  • PostgreSQL support
  • MySQL support
  • MongoDB helpers
  • Built-in pagination
  • Repository integration

Instead of writing raw SQL, developers can now build expressive queries directly from repositories.

🔗 ORM Relationships

TamilPY now supports ORM-style relationships directly inside schema.tpy.

Supported relationships:

  • belongs_to
  • has_one
  • has_many
  • belongs_to_many

It also includes eager loading through:

  • with_()
  • EagerLoader

This makes complex data retrieval significantly cleaner and faster.

⚡ Event System

A brand-new event-driven architecture is now available.

Features include:

  • Event
  • Listener
  • EventDispatcher
  • Wildcard listeners
  • Stop propagation
  • Process singleton support

Perfect for decoupling business logic from application workflows.

🧵 Queue System

Background job processing is now built into TamilPY.

Supported drivers:

  • Sync
  • Database
  • Redis (optional)

New CLI commands:

tpy queue table
tpy queue work
Enter fullscreen mode Exit fullscreen mode

⏰ Scheduler

Schedule recurring jobs with simple cadence helpers.

Features:

  • app/schedule.py

🌐 Standard API Responses

The new ApiResponse class provides consistent JSON responses across every endpoint.

Available responses include:

  • success

  • not_found

No more manually formatting response payloads.

✅ Validation

A completely redesigned validation system featuring:

  • Pipe-rule validation

Simple, expressive, and reusable.

🏗️ Application Kernel

TamilPY now includes a fully featured application kernel.

Capabilities include:

  • Application create()
  • mount()
  • Dependency Injection Container

Lifecycle hooks:

  • boot
  • shutdown
  • before request
  • after request
  • exception
