effected

The unglamorous app plumbing that Effect leaves to you, done right.

A pnpm monorepo (npm org @effected) of Effect v4 libraries designed v4-first, not lifted from their v3 predecessors. The repo holds libraries only; the applications that consume them stay in their own repos.

Every CLI, dev tool, and service reaches for the same machinery: reading and writing config files, parsing and , resolving semver ranges and runtime versions, walking a monorepo's workspaces and lockfiles, shelling out to git, finding the right XDG directory, keeping a little durable state on disk. effected gives you each of those as a typed Effect schema or service — malformed input surfaces as a typed error instead of a thrown exception, IO sits behind layers you can swap in a test, and the whole set shares one design so the pieces fit together.
