Project history and usage

Spago is the PureScript package manager and build tool. It sits in the small-language tooling tradition where a single CLI handles project initialization, dependency resolution, builds, tests, REPL workflows, and publishing.

Project history

The public repository was created in 2018 under the PureScript organization. The current README notes a rewrite of Spago in PureScript and directs users looking for versions up to 0.21.x to the legacy Haskell codebase.

Adoption history

Spago became important in PureScript because it wrapped older ecosystem tools and ideas into one workflow. Its README names Cargo, Stack, psc-package, Pulp, and Bazel as inspirations, and its migration notes explicitly cover moving from `bower` and from the older `spago.dhall` configuration to `spago.yaml`.

How it is used

A typical session is `spago init`, edit `spago.yaml`, then use commands such as `spago run`, `spago build`, `spago test`, `spago repl`, and package-set queries. The README recommends installing with npm across Windows, Linux, and macOS, while Homebrew packages it for users who prefer system package-manager workflows.

Why package nerds care

Spago is interesting to package-tool people because it exposes PureScript's package-set model, registry migration, lock files, monorepo support, and JavaScript output workflow in one CLI. It shows how a niche language ecosystem can converge on Cargo-like ergonomics without simply copying npm.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
