{
“chunkNames”:[],//这个资产包含的块

“emit”:true,//表示资产是否将其输出到`output`目录
“name”:“10.web.js”,//输出文件名
“size”:1058 //文件的大小(以字节为单位)
}
每一个 chunks
表示一组称为 chunk 的模块。每一个对象都满足以下的结构。
{
“entry”:true,//指示块是否包含webpack运行时
“文件”:[
//包含此块的文件名字符串数组
],
“filteredModules”:0,//请参阅上面顶层结构中的说明
“id”:0,//这个块的ID
“initial”:true,//指示此块在初始页面加载或按需加载时是否加载
“模块”:[
//模块对象的列表
“web.jsΔH= 11593e3b3ac85436984a”
],
“名称”:[
//这个块中包含的块名称列表
],
“起源”:[
//请参阅下面的说明...
],
“父母”:[],//父块ID
“rendered”:true,//指示块是否经历了代码生成
“size”:188057 //块大小(以字节为单位)
}
chunks
对象还会包含一个 来源 (origins)
,来表示每一个 chunk 是从哪里来的。 来源 (origins)
是以下的形式
{
"loc": "", // Lines of code that generated this chunk
"module": "(webpack)\\test\\browsertest\\lib\\index.web.js", // Path to the module
"moduleId": 0, // The ID of the module
"moduleIdentifier": "(webpack)\\test\\browsertest\\lib\\index.web.js", // Path to the module
"moduleName": "./lib/index.web.js", // Relative path to the module
"name": "main", // The name of the chunk
"reasons": [
// A list of the same `reasons` found in module objects
]
}
模块对象
{
"assets": [
// A list of asset objects
],
"built": true, // Indicates that the module went through Loaders, Parsing, and Code Generation
"cacheable": true, // Whether or not this module is cacheable
"chunks": [
// IDs of chunks that contain this module
],

"failed": false, // Whether or not compilation failed on this module
"id": 0, // The ID of the module (analagous to `module.id`)
"identifier": "(webpack)\\test\\browsertest\\lib\\index.web.js", // A unique ID used internally

// Module specific compilation stats corresponding to the `--profile` flag (in milliseconds)
"building": 73, // Loading and parsing
"dependencies": 242, // Building dependencies
"factory": 11 // Resolving dependencies
},
"reasons": [
// See the description below...
],
"size": 3593, // Estimated size of the module in bytes
"source": "// Should not break it...\r\nif(typeof...", // The stringified raw source
"warnings": 0 // Number of warnings when resolving or processing the module
}
{
"loc": "33:24-93", // Lines of code that caused the module to be included
"module": "./lib/index.web.js", // Relative path to the module based on context
"moduleId": 0, // The ID of the module
"moduleIdentifier": "(webpack)\\test\\browsertest\\lib\\index.web.js", // Path to the module
"moduleName": "./lib/index.web.js", // A more readable name for the module (used for "pretty-printing")
"type": "require.context", // The type of request used
"userRequest": "../../cases" // Raw string used for the `import` or `require` request
}
错误和警告
在errors
和warnings
特性都包含字符串列表。每个字符串都包含消息和堆栈跟踪:
../cases/parsing/browserify/index.js
Critical dependencies:
2:114-121 This seem to be a pre-built javascript file. Even while this is possible, it's not recommended. Try to require to orginal source to get better results.
@ ../cases/parsing/browserify/index.js 2:114-121
需要注意的是,当 错误详情为false(errorDetails:false)
传入toJson
函数时,对栈的追溯就不会被显示。错误详情(errorDetils)
默认值为 true
