lawnman

Keeps the lawn clean

lawnman runs your npm scripts on changes. Uses nodemon and npm-run-all.

Inspired by yardman.

Install

npm i lawnman -D

Then use lawnman in your package.json scripts:

{
  "scripts": {
    "dev": "lawnman js,json lint test",
    "lint": "eslint lib/ --fix",
    "test": "ava"
  }
}

Usage

lawnman <ext>[,<ext>,...] <script> [<script...>]\
  --and\
  <ext>[,<ext>,...] <script> [<script...>]\
  --and\
  ...

Examples

Run the test script when any js file change.

lawnman js test

Watch js and scss files and compile accordingly

• Runs npm run babel when any js file changes
• Runs npm run compass when any scss or png file changes

lawnman js babel --and scss,png compass

Watch js files and run multiple npm scripts
Runs npm run test and then npm run format when any js files change

lawnman js test format

.lawnmanrc

If you only have one script in package.json that uses lawnman, you can put the arguments into a .lawnmanrc file.

For example, if you have this script in your package.json

{
  "scripts": {
    "dev": "lawnman cpp,cc,h,hpp,gyp rebuild e2e --and js,json lint test --and scss compass",
    "test": "...", ...
  }
}

You can put the arguments into a .lawnmanrc file to clean up your package.json to have it only run lawnman. Empty lines is like --and in the command line. It also supports comments.

# Build addons and run end-to-end tests
cpp,cc,h,hpp,gyp rebuild e2e

# Lint and test javascript
js,json lint test

# Compile scss
scss compass

Your dev script will then look much nicer

{
  "scripts": {
    "dev": "lawnman",
    "test": "...", ...
  }
}
