Spago: PureScript Package Manager and Build Tool

Spago is the official PureScript package manager and build tool, currently at version 1.0.4. It facilitates project initialization, dependency management using a package set model, compilation, and bundling of PureScript applications. The 1.x.x series represents a significant architectural shift, being a complete rewrite of the tool from its original Haskell codebase (versions up to 0.21.x) into PureScript itself. This rewrite aims for improved maintainability and tighter integration with the PureScript ecosystem. Spago provides a streamlined command-line interface for common PureScript development workflows, abstracting away the complexities of managing `purs` compiler invocations and project dependencies. Its release cadence typically involves patch updates for the stable 1.x series, following the major rewrite which occurred with the transition from 0.x to 1.x. A key differentiator is its reliance on curated package sets for consistent and conflict-free dependency resolution within the PureScript ecosystem.
