effect-paths

This provides helpers for working with paths in Effect-TS. Specifically, it provides branded types for absolute vs relative paths, and for directories vs files. This uses Effect v4 Beta.

Installation

npm install effect-paths

Example

// AbsoluteFile
const a = path.join(process.cwd(), RelativeFile("project.json"))

// AbsoluteDir
const b = path.join(process.cwd(), RelativeDir("config"))

// AbsolutePath
const c = path.join(process.cwd(), RelativeDir("config") as RelativePath)

// RelativeDir
const d = path.join(RelativeDir("a"), RelativeDir("b"))

// RelativeFile
const e = path.join(RelativeDir("a"), RelativeFile("package.json"))

// RelativePath
const f = path.join(
  RelativeDir("a"),
  RelativeFile("package.json") as RelativePath,
);

// Error
const g = path.join(RelativeFile("x"), RelativeFile("a"));
