在ASP.NET Core中构建之前如何运行特定的NPM命令？

Question

我正在尝试在ASP.NET Core应用程序中为Angular运行特定的NPM命令。 NPM没什么特别的，它只是准备一些文件。

如何在ASP.NET Core中进行每次构建之前自动运行NPM脚本？

Angular应用程序位于ClientApp文件夹中，其中包含package.json。

之前]自动运行NPM脚本

如果使用默认的角度SPA模板，则应随运行时（即在构建之前）执行的任务设置一起提供。

从默认的角度SPA模板：

<PropertyGroup>
    <SpaRoot>ClientApp\</SpaRoot>
</PropertyGroup>

<ItemGroup>
    <!-- Don't publish the SPA source files, but do show them in the project files list -->
    <Content Remove="$(SpaRoot)**" />
    <None Remove="$(SpaRoot)**" />
    <None Include="$(SpaRoot)**" Exclude="$(SpaRoot)node_modules\**" />
</ItemGroup>

<Target Name="DebugEnsureNodeEnv" BeforeTargets="Build" Condition=" '$(Configuration)' == 'Debug' And !Exists('$(SpaRoot)node_modules') ">
    <!-- Ensure Node.js is installed -->
    <Exec Command="node --version" ContinueOnError="true">
      <Output TaskParameter="ExitCode" PropertyName="ErrorCode" />
    </Exec>
    <Error Condition="'$(ErrorCode)' != '0'" Text="Node.js is required to build and run this project. To continue, please install Node.js from https://nodejs.org/, and then restart your command prompt or IDE." />
    <Message Importance="high" Text="Restoring dependencies using 'npm'. This may take several minutes..." />
    <Exec WorkingDirectory="$(SpaRoot)" Command="npm install" />
</Target>

<Target Name="PublishRunWebpack" AfterTargets="ComputeFilesToPublish">
    <!-- As part of publishing, ensure the JS resources are freshly built in production mode -->
    <Exec WorkingDirectory="$(SpaRoot)" Command="npm install" />
    <Exec WorkingDirectory="$(SpaRoot)" Command="npm run build -- --prod" />
    <Exec WorkingDirectory="$(SpaRoot)" Command="npm run build:ssr -- --prod" Condition=" '$(BuildServerSideRenderer)' == 'true' " />

    <!-- Include the newly-built files in the publish output -->
    <ItemGroup>
        <DistFiles Include="$(SpaRoot)dist\**; $(SpaRoot)dist-server\**" />
        <DistFiles Include="$(SpaRoot)node_modules\**" Condition="'$(BuildServerSideRenderer)' == 'true'" />
        <ResolvedFileToPublish Include="@(DistFiles->'%(FullPath)')" Exclude="@(ResolvedFileToPublish)">
        <RelativePath>%(DistFiles.Identity)</RelativePath>
        <CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
    </ResolvedFileToPublish>
</ItemGroup>

您可以仅在执行某些步骤的脚本的Target文件中添加.csproj。例如，以下命令将在构建服务器应用程序之前运行已安装的gulp.cmd：

<Target Name="RunGulp" BeforeTargets="Build">
  <Exec Command="node_modules\.bin\gulp.cmd" />
</Target>
