Yarn.MSBuild 1.1.0

Usage

This package installs yarn so you can use it from MSBuild without needing to install yarn globally.

YarnBuildCommand

If you set the YarnBuildCommand property, the command will run automatically in the "YarnBuild" target when you compile the application.

Example:

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework>
    <YarnBuildCommand>run webpack</YarnBuildCommand>
    <YarnBuildCommand Condition="'$(Configuration)' == 'Release'">run webpack --env.prod</YarnBuildCommand>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.0" />
    <PackageReference Include="Yarn.MSBuild" Version="1.1.0" />
  </ItemGroup>

</Project>

{
  "scripts": {
    "webpack": "./node_modules/.bin/webpack"
  },
  "dependencies": {
    "react": "^16.0.0"
  },
  "devDependencies": {
    "webpack": "^3.6.0"
  }
}

You can also chain of this target to run additional commands.

  <Target Name="YarnInstall" BeforeTargets="YarnBuild">
    <Yarn Command="install" Condition=" ! Exists('node_modules/')" />
  </Target>

Running yarn from a custom target

This package makes the Yarn task available for execution from your targets.

<Project>
  <Target Name="RunMyYarnCommands">
    
    <Yarn />

    
    <Yarn Command="run myscript" />

    
    <Yarn Command="upgrade" IgnoreExitCode="true" />

    
    <Yarn Command="run test" WorkingDirectory="wwwroot/" />

    
    <Yarn Command="run cmd" NodeJSExecutablePath="/opt/node8/bin/nodejs" />
  </Target>
</Project>
