angularjs - 当文件用 grunt 更改时自动打开浏览器并重新加载它

Question

我不是 grunt 专家，但我有一个 angular js 模板，我想将它用于我的应用程序 我试图在启动 grunt 时自动打开浏览器，并在修改 html、js 和 css 文件时重新加载页面我添加了 watch 和 livereload 但它不起作用是我的代码有问题

这是我的 gruntfile.js

module.exports = function(grunt) {
// Load grunt tasks automatically
require('load-grunt-tasks')(grunt);
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-serve');

var pkg = grunt.file.readJSON('package.json');

var options = {
  paths: {
    app: 'app',
    assets: 'app/assets',
    dist: 'app/dist',
    distAssets: 'app/dist/assets',
    html: 'app/html',
    htmlTmp: '.tmp/htmlsnapshot',
    htmlAssets: 'app/html/assets',
    index: 'app/dist/index.html',
    indexDev: 'app/index.dev.html',
    indexTmp: '.tmp/html/index.html'
  },
  watch: {
    js: {
      files: ['Gruntfile.js', 'app/assets/js/**/*.js'],
      tasks: ['jshint'],
      options: {
        livereload: true
      }
    },
    css: {
      files: [
        'app/assets/css/**/*.scss'
      ],
      tasks: ['sass'],
      options: {
        livereload: true
      }
    },
    livereload: {
      options: {
        livereload: true
      },
      files: [
        'app/assets/tpl/*.html',
        'app/assets/tpl/**/*.html',
        'app/assets/img/{,*/}*.{png,jpg,jpeg,gif,webp,svg}'
      ]
    },
    serve: {
      options: {
        port: 9000,
      },
      files: [
        'app/assets/tpl/*.html',
        'app/assets/tpl/**/*.html',
        'app/assets/img/{,*/}*.{png,jpg,jpeg,gif,webp,svg}'
      ]
    }
  },
  connect: {
    options: {
      port: 9000,
      // Change this to '0.0.0.0' to access the server from outside.
      hostname: 'localhost',
      livereload: 35729
    }
  },
  // debug while developing
  jshint: {
    all: ['Gruntfile.js', 'app/js/**/*.js']
  },
  pkg: pkg
};

// Load grunt configurations automatically
var configs = require('load-grunt-configs')(grunt, options);

// Define the configuration for all the tasks
grunt.initConfig(configs);

grunt.registerTask('bumper', ['bump-only']);
grunt.registerTask('css', ['sass']);
grunt.registerTask('default', [
  'sass',
  'copy:dev',
  'connect',
  'watch',
  'serve'
]);

grunt.registerTask('shared', [
  'clean:demo',
  'copy:demo',
  'sass',
  'ngconstant',
  'useminPrepare',
  'concat:generated',
  'cssmin:generated',
  'uglify:generated',
  'filerev',
  'usemin',
  'imagemin',
  'usebanner'
]);

grunt.registerTask('demo', [
  'shared',
  'copy:postusemin', 
  'grep:demo'
]);

grunt.registerTask('dist', [
  'shared',
  'copy:postusemin',
  'copy:dist',
  'grep:dist',
  'html',
  'compress',
  'copy:postusemin',
  'grep:demo',
]);

grunt.registerTask('html', [
  'clean:html',
  'copy:html',
  'concat:html',
  'uglify:html',
  'cssmin:html',
]);
};

我找到了解决我的问题的方法
为了自动打开浏览器，我在 Gruntfile 配置中添加了参数 livereload 以连接对象

connect: {
  options: {
    livereload: true,
    hostname: 'localhost',
    base: 'app',
    port: 9000
  },
  proxies: [
    {
      context: [
        '/_ah',
        '/secured',
        '/oauth2login',
        '/oauth2callback'
      ],
      host: 'localhost',
      port: 8080,
      https: false,
      changeOrigin: false,
      xforward: false
    }
  ],
  livereload: {
    options: {
      open: true
    }
  }
}

现在浏览器会自动打开
