.net - 如何在生产模式下发布 Angular 文件？

问题描述

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

下面是我的 .csproj：

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

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

  <ItemGroup>
    <PackageReference Include="CsvHelper" Version="12.1.1" />
    <PackageReference Include="EPPlus" Version="4.5.3.1" />
    <PackageReference Include="Microsoft.AspNetCore.App" />
    <PackageReference Include="Microsoft.AspNetCore.Razor.Design" Version="2.2.0" PrivateAssets="All" />
    <PackageReference Include="Sendgrid" Version="9.10.0" />
    <PackageReference Include="WindowsAzure.Storage" Version="9.3.3" />
  </ItemGroup>

  <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>
  </Target>

</Project>

原来“npm run build --prod”没有运行，因为 angular 不在生产模式下。我如何做到这一点，以便我在 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？

解决方案

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 ( )。
