## What it is
Yalc is a CLI tool that manages a local store of npm/yarn packages so you can test locally developed packages in other projects without publishing to a remote registry. It improves on npm/yarn link by copying published package content and injecting file: dependencies instead of relying on symlinks.

## Use cases
- test a local package in another project without publishing to npm
- replace npm link / yarn link workflow for package authors
- develop multiple interdependent packages locally
- inject a WIP package version into a project's package.json
- share unpublished packages across local projects

## When to choose
- you author npm/yarn packages and need to test them in consuming projects before publishing
- symlink-based npm/yarn link causes dependency resolution or filesystem problems
- you work with yarn, npm, or pnpm workspaces and need local package injection

## When to avoid
- you only consume published packages and never develop packages locally
- your project uses package managers other than npm/yarn/pnpm for package.json dependencies
- you need full monorepo dependency hoisting rather than single-package injection
