RequireJS如何从jam文件包部分指定填充依赖项

Question

我在一个使用backbone-boilerplate的项目中工作，这个项目使用RequireJS来加载模块，使用JamJS来管理它们。我需要的config.js文件如下：

require.config({
  deps: ["../vendor/jam/require.config", "main"],
  paths: {
    "backbone.localStorage": "../vendor/backbone.localStorage-1.0/backbone.localStorage"
  },
  shim: {
    "backbone.localStorage": {
        deps: ['backbone']
    }
  }
});

正如您可以从jam配置文件jam/require.config.js中看到的RequireJS加载配置，它指定了backbone、jquery和下划线。接下来是文件的一部分：

    "packages": [
        {
            "name": "backbone.layoutmanager",
            "location": "../vendor/jam/backbone.layoutmanager",
            "main": "backbone.layoutmanager.js"
        }
        {
            "name": "backbone",
            "location": "../vendor/jam/backbone",
            "main": "backbone.js"
        }
    ],
    "version": "0.2.11",
    "shim": {
        "backbone.layoutmanager": {
            "deps": [
                "jquery",
                "backbone",
                "lodash"
            ],
            "exports": "Backbone.LayoutManager"
        }
        "backbone": {
            "deps": [
                "jquery",
                "lodash"
            ],
            "exports": "Backbone"
        }
    }
};

我想要在我的config.js中指定backbone.localStorare库依赖于package部分中定义的backbone。同样，如果我按如下方式指定backbone路径，那么它找到了backbone库，但发现了一条错误消息，指出下划线未加载：

require.config({
  deps: ["../vendor/jam/require.config", "main"],
  paths: {
    "backbone": "../vendor/jam/backbone/backbone",
    "backbone.localStorage": "../vendor/backbone.localStorage-1.0/backbone.localStorage"
  },
  shim: {
    "backbone.localStorage": {
        deps: ['backbone']
    }
  }
});

我可以使用jamjs添加backbone.localStorage库，但是可用的包的版本是旧的，所以我更喜欢手动下载最后一个包并手动包含。

任何想法或帮助都将不胜感激。

Answer 1

Backbone需要Underscore & jQuery

shim: {
    "backbone": {
       "deps": [ "underscore", "jquery" ],
       "exports": "Backbone"  //attaches "Backbone" to the window object
    },
    "underscore": {
       "exports": "_"
    }
}

所以我认为你最好调整一下你的jam/require.config.js。

编辑：

接下来，你问题中的packages部分，它是jam/require.config.js的一部分吗？位置相对于jam/require.config.js的位置

"packages": ["backbone", "backbone.layoutmanager"]

多亏了asgoth我才能解决这个问题。我把文件放在下面。

有了这个配置，我可以将填充库放在我的config.js文件中，该文件依赖于require.config.js文件中jam管理的包。

the config.js

// Set the require.js configuration for your application.
require.config({

  // Initialize the application with the main application file and the JamJS
  // generated configuration file.
  deps: ["../vendor/jam/require.config", "main"],

  // Packeges defined at jam/require.config.js required by shim libraries
  packages: [
    {"name" : "backbone"}, 
    {"name" : "jquery"}
  ],

  paths: {
    // Put paths here.
    "codemirror" : "../vendor/codemirror-3.0/lib/codemirror",
    "codemirror-markdown": "../vendor/codemirror-3.0/mode/markdown/markdown",
    "backbone.localStorage": "../vendor/backbone.localStorage-1.0/backbone.localStorage",
    "bootstrap" : "../vendor/bootstrap-2.2.2/js/bootstrap"
  },

  shim: {
    // Put shims here.
    "codemirror-markdown": {
      deps: ["codemirror"]
    },
    "backbone.localStorage": {
      deps: ['backbone']
    },
    "bootstrap": {
      deps: ['jquery']
    }
  }

});

the require.config.js

var jam = {
    "packages": [
        {
            "name": "jquery",
            "location": "../vendor/jam/jquery",
            "main": "jquery.js"
        },
        {
            "name": "backbone.layoutmanager",
            "location": "../vendor/jam/backbone.layoutmanager",
            "main": "backbone.layoutmanager.js"
        },
        {
            "name": "underscore",
            "location": "../vendor/jam/underscore",
            "main": "underscore.js"
        },
        {
            "name": "backbone",
            "location": "../vendor/jam/backbone",
            "main": "backbone.js"
        },
        {
            "name": "lodash",
            "location": "../vendor/jam/lodash",
            "main": "./lodash.js"
        }
    ],
    "version": "0.2.11",
    "shim": {
        "backbone.layoutmanager": {
            "deps": [
                "jquery",
                "backbone",
                "lodash"
            ],
            "exports": "Backbone.LayoutManager"
        },
        "underscore": {
            "exports": "_"
        },
        "backbone": {
            "deps": [
                "jquery",
                "lodash"
            ],
            "exports": "Backbone"
        }
    }
};

if (typeof require !== "undefined" && require.config) {
    require.config({packages: jam.packages, shim: jam.shim});
}
else {
    var require = {packages: jam.packages, shim: jam.shim};
}

if (typeof exports !== "undefined" && typeof module !== "undefined") {
    module.exports = jam;
}
