## What it is
tsc-alias is an npm CLI tool and library that rewrites TypeScript path aliases to relative import paths after tsc compilation. It runs as a post-build step so compiled JavaScript output has no runtime dependency on tsconfig path mappings.

## Use cases
- replace tsconfig path aliases with relative paths after tsc build
- make compiled output work without runtime path registration
- resolve full import paths with .js extensions for ESM compatibility
- watch mode alias rewriting alongside tsc -w
- use path aliases referencing projects outside the tsconfig baseUrl
- programmatically rewrite alias paths via the replaceTscAliasPaths API

## When to choose
- you use tsc to build and rely on tsconfig paths aliases
- you want compile-time alias resolution with no runtime dependencies
- you need ESM-compatible fully resolved import extensions in output

## When to avoid
- you use a bundler like webpack, esbuild, or tsup that resolves aliases itself
- you prefer runtime path resolution via tsconfig-paths
- your project does not use TypeScript path aliases
