如何在npm脚本中使用“监视”？

node.js

我的package.json样子是这样的：

{
  "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"
  }
}

因此，首先，我必须分别运行每个脚本，例如npm run node-sassor npm run html- minifier等。我理想的情况是运行npm serve将执行以下操作的脚本：

  1. 运行html-minifier
  2. 运行节点ass
  3. 运行图像最小
  4. 运行http服务器
  5. 最后，观看我src文件夹中的所有内容，并在文件更改（例如，node-sass等）时运行相应的脚本。

我怎样才能最好地解决这个问题？

您可以使用查看目录nodemon。

一个适合您的解决方案是创建三个监视脚本，每个任务一个：

  • watch:node-sass，
  • watch:html-minifier和
  • watch:imagemin。

然后，以中央脚本watch开始这三个脚本：

{
  "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",
    "watch:node-sass": "nodemon -e scss -x \"npm run node-sass\"",
    "watch:html-minifier": "nodemon -e html -x \"npm run html-minifier\"",
    "watch:imagemin": "nodemon --watch src/images -x \"npm run imagemin\"",
    "watch": "npm run watch:node-sass & npm run watch:html-minifier & npm run watch:imagemin"
  },
  "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"
  }
}
