在 ng serve 构建 Angular 库

Question

我正在为我的 Angular 库开发而苦苦挣扎。首先，我正在构建一个 Angular 8 库（当前 cli 版本 9），并且我希望在为使用该库的演示应用程序提供服务时实时看到我的库代码更改。

当前行为：当我对库源代码进行更改时，角度演示应用程序会重新加载，但我没有看到任何更改生效。此行为主要应用于 css 更改，而不是每次都应用于 .ts 文件。

预期行为：能够看到我对库源代码所做的每一项更改。

当前的 angular.json 文件

          }
        }
      }
    }
  },
  "defaultProject": "bDataTableDemo"
}

还有我的 tsconfig.json 文件

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "downlevelIteration": true,
    "experimentalDecorators": true,
    "module": "esnext",
    "moduleResolution": "node",
    "importHelpers": true,
    "target": "es2015",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2018",
      "dom"
    ],
    "paths": {
      "ng-bootstrap-table": [
        "dist/ng-bootstrap-table"
      ],
      "ng-bootstrap-table/*": [
        "dist/ng-bootstrap-table/*"
      ]
    }
  },
  "angularCompilerOptions": {
    "fullTemplateTypeCheck": true,
    "strictInjectionParameters": true
  }
}

为了获得预期的行为，我应该改变什么？

附：我是 Angular 库的新手，所以我还找不到解决方案。

提前谢谢你！！

您应该编辑 tsconfig 中的路径以指向您的库的 index.ts 而不是 dist/ - 这是使用 ng build my-library 生成的构建工件：

"my-library" : [ "libs/my-library/index.ts" ]
