How can I use 'watch' in my npm scripts?

I have the following directory structure:

enter image description here

And mine package.jsonlooks like this:

{
  "name": "personal_site",
  "version": "1.0.0",
  "description": "My personal website.",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "node-sass": "node-sass --output-style compressed --include-path node_modules/bourbon/app/assets/stylesheets/ --include-path node_modules/bourbon-neat/app/assets/stylesheets/ 'src/scss/styles.scss' 'dist/css/bundle.min.css'",
    "html-minifier": "html-minifier --collapse-whitespace --remove-comments --remove-attribute-quotes -o 'dist/index.html' 'src/index.html'",
    "imagemin": "imagemin src/images dist/images",
    "serve": "http-server ./dist"
  },
  "author": "Dean Gibson",
  "license": "ISC",
  "dependencies": {
    "bourbon": "^4.2.6",
    "bourbon-neat": "^1.7.4",
    "normalize-scss": "^4.0.3"
  },
  "devDependencies": {
    "html-minifier": "^1.3.0",
    "http-server": "^0.9.0",
    "node-sass": "^3.4.2"
  }
}

So, firstly, I have to run each of these scripts separately, for example. npm run node-sassor npm run html-minifieretc. Ideally, I want to run npm serve, which will do the following:

  • run html- minifier
  • run node-sass
  • run run image-min
  • start http server
  • Finally, browse through everything in my folder srcand run the appropriate scripts, such as files, for example, node-sassetc.

How can I best solve this problem?
