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他的浏览器缓存。原来角度文件无法正确构建。或者更准确地说，它们是构建的，但是它们的名称不会被散列，这会产生与先前版本相同的名称，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>

  </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">

    <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不处于生产模式。我如何制作它，以便我的生产发布设置在Visual Studio构建角度生产模式，而我的开发服务器获得开发构建？

Answer 1

将命令更改为qazxsw poi。 这将qazxsw poi参数传递给underling npm run build -- --prod命令，因此将执行正确的命令（prod）。

Answer 2

如果你查看你的ng build文件，ng build --prod命令运行package.json。即使您指定了build，选项也不会转换为ng build中的命令。这里有几个选项。

在--prod文件中，您可以创建另一个生产命令。

package.json

然后你可以运行package.json。或者作为第二个选项，您可以简单地运行angular-cli命令

"scripts": {
  ...
  "build": "ng build",
  "build-prod": "ng build --prod"
  ...  
},

Answer 3

执行构建命令--prod
