angularjs - Yeoman Angular 应用程序，grunt watch .less 文件

Question

我在玩 Yeoman、grunt、bower、bootstrap 和 yo Angular 应用程序。我试图让 grunt watch .less 文件，但我遇到了一些麻烦。
我当然已经安装了 grunt-contrib-less 模块

npm install grunt-contrib-less --save-dev

并将其保存到我的 package.json 中。

我已经能够使用以下代码在其他项目中完成这项工作:

  module.exports = function(grunt){
        grunt.initConfig({
            pkg:grunt.file.readJSON('package.json'),
            less:{
                development:{
                        options: {
                            paths: ['bower_components/bootstrap/less', 'bower_components/bootstrap/dist/css'],
                                   yuicompress: true
                        },
                    files:{
                        'bower_components/bootstrap/dist/css/bootstrap.css' : 'bower_components/bootstrap/less/bootstrap.less',
                    }
                }
            },
            // running 'grunt watch' will watch for changes
            watch: {
                files: ['bower_components/bootstrap/less/*.less', 'bower_components/bootstrap/less/*.less'],
                       tasks: ['less']
            }
        });

        grunt.loadNpmTasks('grunt-contrib-less');
        grunt.loadNpmTasks('grunt-contrib-watch');
        grunt.registerTask('default',['less']);
    };

和:

module.exports = function(grunt) {
      grunt.initConfig({
          less: {
              development: {
                  options: {
                      paths: ["bower_components/bootstrap/less"],
                      yuicompress: true
                  },
                  files: {
                      "bower_components/bootstrap/dist/css/bootstrap.css": "bower_components/bootstrap/less/bootstrap.less"
                  }
              }
          },
          watch: {
              files: "bower_components/bootstrap/less/*",
              tasks: ["less"]
          }
      });
      grunt.loadNpmTasks('grunt-contrib-less');
      grunt.loadNpmTasks('grunt-contrib-watch');
};

但我之前没有尝试过使用 Angular 应用程序。它也可能像我做错路由一样简单，但我现在已经尝试了很多次，我不确定是不是这样。

我已经在 Gruntfile.js 中有一些监视代码

watch: {
      bower: {
        files: ['bower.json'],
        tasks: ['bowerInstall']
      },
      js: {
        files: ['<%= yeoman.app %>/scripts/{,*/}*.js'],
        tasks: ['newer:jshint:all'],
        options: {
          livereload: true
        }
      },
      jsTest: {
        files: ['test/spec/{,*/}*.js'],
        tasks: ['newer:jshint:test', 'karma']
      },
      styles: {
        files: ['<%= yeoman.app %>/styles/{,*/}*.css'],
        tasks: ['newer:copy:styles', 'autoprefixer']
      },
      gruntfile: {
        files: ['Gruntfile.js']
      },
      livereload: {
        options: {
          livereload: '<%= connect.options.livereload %>'
        },
        files: [
          '<%= yeoman.app %>/{,*/}*.html',
          '.tmp/styles/{,*/}*.css',
          '<%= yeoman.app %>/images/{,*/}*.{png,jpg,jpeg,gif,webp,svg}'
        ]
      }
    },

并且想要类似的东西(我认为不是真正的功能代码)

less: {
  files: [
    '<%= yeoman.app %>/{,*/something.something}*.less'
  ]
  tasks: ['less:developer']
},

观看 .less 文件并尽可能将其制成 css 文件。

Answer 1

答案很简单，因为我在问题中有解决方案代码。对我来说唯一困难的是在哪里以及如何放置它。

首先，我安装了 grunt-contrib-less 模块，并在我的样式文件夹中而不是在 bower_components 中创建了另一个 bootstrapless 文件夹(谢谢 Mingos!)。
然后我更新了 Gruntfile，这就是它现在的样子:

'use strict';

// # Globbing
// for performance reasons we're only matching one level down:
// 'test/spec/{,*/}*.js'
// use this if you want to recursively match all subfolders:
// 'test/spec/**/*.js'

module.exports = function (grunt) {

  // Load grunt tasks automatically
  require('load-grunt-tasks')(grunt);

  // Time how long tasks take. Can help when optimizing build times
  require('time-grunt')(grunt);

  // Define the configuration for all the tasks
  grunt.initConfig({

    // Project settings
    yeoman: {
      // configurable paths
      app: require('./bower.json').appPath || 'app',
      dist: 'dist'
    },
    less: {
        development: {
            options: {
                compress: true,
                yuicompress: true,
                optimization: 2
            },
            files: {
                // target.css file: source.less file
                "app/styles/bootstrap.css": "app/styles/less/bootstrap.less"
            }
        }
    },

    // Watches files for changes and runs tasks based on the changed files
    watch: {
      bower: {
        files: ['bower.json'],
        tasks: ['bowerInstall']
      },
      js: {
        files: ['<%= yeoman.app %>/scripts/{,*/}*.js'],
        tasks: ['newer:jshint:all'],
        options: {
          livereload: true
        }
      },
      jsTest: {
        files: ['test/spec/{,*/}*.js'],
        tasks: ['newer:jshint:test', 'karma']
      },
      styles: {
        files: ['<%= yeoman.app %>/styles/{,*/}*.css', '<%= yeoman.app %>/styles/less/{,*/}*.less'],
        tasks: ['newer:copy:styles', 'autoprefixer', 'less']
      },
      gruntfile: {
        files: ['Gruntfile.js']
      },
      livereload: {
        options: {
          livereload: '<%= connect.options.livereload %>'
        },
        files: [
          '<%= yeoman.app %>/{,*/}*.html',
          '.tmp/styles/{,*/}*.css',
          '<%= yeoman.app %>/images/{,*/}*.{png,jpg,jpeg,gif,webp,svg}'
        ]
      }
    },

    // The actual grunt server settings
    connect: {
      options: {
        port: 9000,
        // Change this to '0.0.0.0' to access the server from outside.
        hostname: 'localhost',
        livereload: 35729
      },
      livereload: {
        options: {
          open: true,
          base: [
            '.tmp',
            '<%= yeoman.app %>'
          ]
        }
      },
      test: {
        options: {

          base: [
            '.tmp',
            'test',
            '<%= yeoman.app %>'
          ]
        }
      },
      dist: {

        }]
      }
    },

    // Automatically inject Bower components into the app

如您所见，这在我的样式文件夹中创建了一个新的 bootstrap.css，然后我从 index.html 链接了该文件夹:)
