Drop-in Symfony bundle for currency conversion: configurable services, multi-provider exchange rates with fallback and caching.

  • php
  • symfony
  • exchange-rates
  • currency-conversion

Server-side framework for Dart/Dartlang with a built-in middleware system.

Counter caches for Rails computed from any block, such as conditional counts or sums, kept up to date by callbacks on any number of models and stored in a column, a shared counters table or your cache store. Recounts run after commit, so concurrent saves can't leave a stale value.

Lightweight DataFrame validation decorators for Pandas, Polars, Modin, and PyArrow. No custom types required.

Multi-agent orchestration & workflow engine. Declarative YAML workflows, LLM coordinator with hub-and-spoke mailboxes, race-safe delivery. One YAML file, one Go binary. Runs on any goai-supported provider.

A fast and optimized middleware server with an absurdly small amount of code (300 lines) built on top of native HTTP APIs with no dependencies. It also has a collection of useful middlewares: log file, serve static, CORS, session, rate limit, token, body parsers, redirect, proxy and handle upload. For Deno Deploy and other enviroments!

Zero-dependency Go input validation, in-place normalization, and JSON Schema generation from struct tags.
