Readme for atelier-core-0.4.0.1

[back to package description]

atelier-core

Foundational effects and utilities for effect-based applications, built on Effectful. Part of the atelier toolkit.

Overview

atelier-core provides a set of composable Effectful effects and supporting types for building structured, observable applications.

Module Purpose
Atelier.Component Structured component lifecycle (setup → listeners → start)
Atelier.Config Configuration with environment variable overrides
Atelier.Effects.Log Structured logging with hierarchical namespaces
Atelier.Effects.Conc Thread management via Ki (structured concurrency)
Atelier.Effects.Cache Caching with singleflight deduplication
Atelier.Effects.Publishing Event publishing with context propagation
Atelier.Effects.Monitoring.Tracing OpenTelemetry tracing
Atelier.Effects.Monitoring.Metrics Prometheus metrics
Atelier.Effects.FileWatcher Filesystem change notifications
Atelier.Effects.Process External process management

It also wraps a number of IO-based primitives (environment, clock, file system, console, POSIX) as effects so they can be interpreted and tested explicitly: Atelier.Effects.Env, Atelier.Effects.Clock, Atelier.Effects.FileSystem, Atelier.Effects.Console, Atelier.Effects.Posix.*, and more.
