VueCliMiddleware - Supporting Vue Cli and Quasar Cli

This is a stand-alone module to add Vue Cli and Quasar Cli support to AspNet Core.

See the examples here: https://github.com/EEParker/aspnetcore-vueclimiddleware/tree/master/samples

ASP.NET 3.X Endpoint Routing

First, be sure to switch Vue Cli or Quasar Cli to output distribution files to wwwroot directly (not dist).

Quasar CLI: regex: "Compiled successfully"
Vue CLI: regex: "Compiled successfully" or "running at" or "Starting development server" depending on version

the reason for Starting development server ,the npm-script running checkpoint: Although the dev server may eventually tell us the URL it's listening on, it doesn't do so until it's finished compiling, and even then only if there were no compiler warnings. So instead of waiting for that, consider it ready as soon as it starts listening for requests.see the codes

Configuration Options

When using the MapToVueCliProxy or UseVueCli you can customize the behavior based on your npm script runner or compiler.

Parameter	Type	Description	Default
`npmScript`	string	The name of the script in your package.json file that launches the vue-cli, quasar cli or other web server.
`spaOptions`	SpaOptions	Set the folder of the app to be proxied.
`port`	int	Specify the vue cli server port number. This is also used by the force-kill option to discover processes utilizing the port.	8080
`https`	bool	Set proxy to use https	false
`runner`	`enum { Npm, Yarn }`	Specify the runner, Npm and Yarn are valid options. Yarn support is experimental.	Npm
`regex`	string	IMPORTANT Text to search in npm log that indicates web server is running. This MUST BE SET for vue-cli, quasar and quasar v2. (e.g. `running at`, `READY`, `APP Url`)	`running at`
`forceKill`	bool	Attempt to kill the npm process when stopping debugging.	false
`wsl`	bool	Set to true if you are using WSL on windows. For other operating systems it will be ignored. This changes the executed process name to `wsl` instead of `cmd`.	false

    public class Startup {

        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            // NOTE: PRODUCTION Ensure this is the same path that is specified in your webpack output
            services.AddSpaStaticFiles(opt => opt.RootPath = "ClientApp/dist");
            services.AddControllers();
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
	    // optional base path for IIS virtual app/directory
	    app.UsePathBase("/optionalpath");
            
	    // PRODUCTION uses webpack static files
            app.UseSpaStaticFiles();

            // Routing
            app.UseRouting();
            app.UserAuthorization();
            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();

                endpoints.MapToVueCliProxy(
                    "{*path}",
                    new SpaOptions { SourcePath = "ClientApp" },
                    npmScript: (System.Diagnostics.Debugger.IsAttached) ? "serve" : null,
                    regex: "Compiled successfully",
                    forceKill: true,
		    wsl: false // Set to true if you are using WSL on windows. For other operating systems it will be ignored
                    );
            });
        }
    }

ASP.NET 2.2 Usage Example

    using VueCliMiddleware;

    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        public virtual void ConfigureServices(IServiceCollection services)
        {
           services.AddMvc(); // etc
           
           // Need to register ISpaStaticFileProvider for UseSpaStaticFiles middleware to work
           services.AddSpaStaticFiles(configuration => { configuration.RootPath = "ClientApp/dist"; });
        }

        public virtual void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
           // your config opts...
		   // optional basepath
		   // app.UsePathBase("/myapp");

           // add static files from SPA (/dist)
          app.UseSpaStaticFiles();

          app.UseMvc(routes => /* configure*/ );

          app.UseSpa(spa =>
            {
                spa.Options.SourcePath = "ClientApp";
#if DEBUG
                if (env.IsDevelopment())
                {
                    spa.UseVueCli(npmScript: "serve", port: 8080); // optional port
                }
#endif
            });
        }
    }

CSPROJ Configuration

You may also need to add the following tasks to your csproj file. This are similar to what are found in the default ASPNETSPA templates.

  <PropertyGroup>
    <!-- Typescript/Javascript Client Configuration -->
    <SpaRoot>ClientApp\</SpaRoot>
    <DefaultItemExcludes>$(DefaultItemExcludes);$(SpaRoot)node_modules\**</DefaultItemExcludes>
  </PropertyGroup>
  <Target Name="DebugEnsureNodeEnv" BeforeTargets="Build">
    <!-- Build Target:  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." />
  </Target>

  <Target Name="DebugEnsureNpm" AfterTargets="DebugEnsureNodeEnv">
    <!-- Build Target:  Ensure Node.js is installed -->
    <Exec Command="npm --version" ContinueOnError="true">
      <Output TaskParameter="ExitCode" PropertyName="ErrorCode" />
    </Exec>
  </Target>

  <Target Name="EnsureNodeModulesInstalled" BeforeTargets="Build" Inputs="package.json" Outputs="packages-lock.json">
    <!-- Build Target: Restore NPM packages using npm -->
    <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">
    <!-- Build Target: Run webpack dist build -->
    <Message Importance="high" Text="Running npm build..." />
    <Exec WorkingDirectory="$(SpaRoot)" Command="npm run build" />

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