Question

我有以下问题，当我在监视模式下使用webpack并将结果写入文件时，webpack没有替换旧数据，而是附加了新数据。运行构建时，一切正常，旧数据替换为新数据。

有没有一种方式使watchmode也覆盖数据而不是附加数据？

这些是我使用的参数

webpack --env development --watch --json > stats.json

官方文档在这里没有提示

Stats Data Documentation

例如，文件stats.json为空。因此，我运行命令批准，然后将以下内容写入文件。

{
  "version": "1.4.13", // Version of webpack used for the compilation
  "hash": "11593e3b3ac85436984a", // Compilation specific hash
  "time": 2469, // Compilation time in milliseconds
  "filteredModules": 0, // A count of excluded modules when `exclude` is passed to the `toJson` method
  "outputPath": "/", // path to webpack output directory
  "assetsByChunkName": {
    // Chunk name to emitted asset(s) mapping
    "main": "web.js?h=11593e3b3ac85436984a",
    "named-chunk": "named-chunk.web.js",
    "other-chunk": [
      "other-chunk.js",
      "other-chunk.css"
    ]
  },
  "assets": [
    // A list of asset objects
  ],
  "chunks": [
    // A list of chunk objects
  ],
  "modules": [
    // A list of module objects
  ],
  "errors": [
    // A list of error strings
  ],
  "warnings": [
    // A list of warning strings
  ]
}

因此，现在我的文件中发生了一些更改，观察者检测到了这一点并重新运行。因此，他再次将输出输出到文件。但是它只会附加它，所以看起来像这样

{
  "version": "1.4.13", // Version of webpack used for the compilation
  "hash": "11593e3b3ac85436984a", // Compilation specific hash
  "time": 2469, // Compilation time in milliseconds
  "filteredModules": 0, // A count of excluded modules when `exclude` is passed to the `toJson` method
  "outputPath": "/", // path to webpack output directory
  "assetsByChunkName": {
    // Chunk name to emitted asset(s) mapping
    "main": "web.js?h=11593e3b3ac85436984a",
    "named-chunk": "named-chunk.web.js",
    "other-chunk": [
      "other-chunk.js",
      "other-chunk.css"
    ]
  },
  "assets": [
    // A list of asset objects
  ],
  "chunks": [
    // A list of chunk objects
  ],
  "modules": [
    // A list of module objects
  ],
  "errors": [
    // A list of error strings
  ],
  "warnings": [
    // A list of warning strings
  ]
}{
  "version": "1.4.13", // Version of webpack used for the compilation
  "hash": "11593e3b3ac85436984a", // Compilation specific hash
  "time": 2469, // Compilation time in milliseconds
  "filteredModules": 0, // A count of excluded modules when `exclude` is passed to the `toJson` method
  "outputPath": "/", // path to webpack output directory
  "assetsByChunkName": {
    // Chunk name to emitted asset(s) mapping
    "main": "web.js?h=11593e3b3ac85436984a",
    "named-chunk": "named-chunk.web.js",
    "other-chunk": [
      "other-chunk.js",
      "other-chunk.css"
    ]
  },
  "assets": [
    // A list of asset objects
  ],
  "chunks": [
    // A list of chunk objects
  ],
  "modules": [
    // A list of module objects
  ],
  "errors": [
    // A list of error strings
  ],
  "warnings": [
    // A list of warning strings
  ]
}

但是我希望它替换旧数据，因此文件中仍然只有一个结果。
