+# `yaln` (Yet another local npm)
+
+While developing some libraries I noticed that `npm link`, `yarn link` and also partially `yalc` sometimes have problem 
+when it comes to mimicking the publish process and create an acutally working local environment.
+
+So `yaln` will simply "create" a simple local npm registry.
+
+It will:
+- Use `npm pack` to create an actual npm package file and store it in `~/.yaln/packages/`.
+- It will watch for changes of packages in `~/.yaln/packages/` and installs them locally.
+
+## Install
+
+    git clone ...
+    cd ...
+    npm i -g .
+
+Currently, there is no npm package available.
+
+## Update
+
+Simply git pull.
+
+
+
+## Usage
+
+### In source project 
+
+#### tsc-watch
+
+    tsc-watch --onSuccess "yaln pack"
+
+#### Rollup
+
+    rollup -c --watch --watch.onBundleEnd="yaln pack"
+
+    npm run watch --watch.onBundleEnd="yaln pack"
+
+### In target project
+
+    yaln watch [package list]
+
+### Pre commit hook
+
+Simple pre commit hook to ensure no file references in package json get committed:
+
+```yaml
+      - id: no-relative-packages
+        name: no-relative-packages
+        entry: bash -c "git diff --cached --name-only | grep -q 'package.json' && cat package.json | grep -E 'file:.+\/\.yaln\/.+' && echo -e 'file references not allowed in package.json' 1>&2 && exit 1 || exit 0"
+        language: system
+        pass_filenames: false
+```
+
+# Known bugs
+
+- Looks like sometimes, when the first package update gets detected, the package gets installed twice
+
+# Missing features
+
+- Support `yarn`
+- Add command to add dependency without watch
+- Allow configuration of exchangePath
+- Add CommonJS support
