如何为 Angular CLI 的新配置启用增量构建模式？
How to enabIe incremental build mode for a new configuration for the Angular CLI?
我正在做一个 Angular 项目。
我尝试为 Angular CLI 定义一个新的 "development"-configuration。
我已经可以做到了：
ng serve -c=development
但当我更改一段代码时，它始终是一个完整的构建。
当我在同一个项目中使用 ng serve 而没有 -c 选项时，当我更改某些内容时，只会发生一个很小的构建。
（"incremental build" 一词是否适合描述这种行为？）
我也想让 CLI 使用“-c=development”来完成这个小构建。
我试图在 Angular 文档和 Google 中找到它，但我无法弄明白。
我的angular.json是（只是改了工程名）：

如有任何帮助，我将不胜感激。
请善待。上一次我需要三四次编辑才能让我的问题获得所需的所有信息并具有适当的风格，尽管我总是在第一次尝试时就做到这一点。谢谢！
更新：
在猜测模式下，我发现了一个可以使构建方式比以前更快的东西。不如没有 -c-选项快，但这是一个好的开始：
"configurations": {
"development": {
"optimization": false,
我设置优化-属性 false.
但我真的很感激进一步的帮助、内部和改进。谢谢！
我找到了一个令人满意的解决方案。
angular.js 的配置部分中配置条目的属性与 ng build 的命令行选项相同（至少有很多）。所以在 ng build 的文档中我找到了不同属性的默认值。
我更改了以下属性：
- "optimization": 假
- "buildOptimizer": 错误,
- "aot": 错误,
- "outputHashing": "none",
- "namedChunks"：正确，
- "extractLicenses": 错误,
所以我的 "development"-configuration-entry 现在看起来像这样：
"configurations": {
"development": {
"fileReplacements": [
{
"replace": "src/environments/environment.ts",
"with": "src/environments/environment.dev.ts"
}
],
"optimization": false,
"outputHashing": "none",
"sourceMap": false,
"extractCss": true,
"namedChunks": true,
"aot": false,
"extractLicenses": false,
"vendorChunk": false,
"buildOptimizer": false,
"budgets": [
{
"type": "initial",
"maximumWarning": "2mb",
"maximumError": "5mb"
}
]
},
现在我得到的构建时间与没有 -c 选项时一样。
也许配置中有更多设置不是开发的最佳设置，但就目前而言，我对此感到满意。
编码愉快。玩得开心！
