如何在生产模式下发布角度文件？

Question

我一直想知道为什么我的客户总是需要为我的网站清除浏览器缓存。原来角度文件没有正确构建。或者更准确地说，它们得到了构建，但它们的名称不会被散列，这导致与以前的版本名称相同，因此浏览器认为没有任何变化。

以下是我的 .csproj：

    <Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>
    <TypeScriptCompileBlocked>true</TypeScriptCompileBlocked>

    <IsPackable>false</IsPackable>
    <SpaRoot>ClientApp\</SpaRoot>
    <DefaultItemExcludes>$(DefaultItemExcludes);$(SpaRoot)node_modules\**</DefaultItemExcludes>

    <!-- Set this to true if you enable server-side prerendering -->
    <BuildServerSideRenderer>false</BuildServerSideRenderer>
    <UserSecretsId>c69ca95c-16a6-4f76-bb29-b4d09b2a4417</UserSecretsId>

  <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" />

    <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>
  </Target>

</Project>

原来“npm run build --prod”没有运行，因为 angular 不在生产模式下。如何使我在 Visual Studio 中的生产发布设置在生产模式下构建 angular，而我的开发服务器获得开发构建？

Answer 1

将命令更改为npm run build -- --prod.
这会将prod参数传递给下级ng build命令，因此ng build --prod将执行正确的命令 ( )。
