Asp.net core 2/Angular 4 template build not working

Question

I have created project using Asp.net core 2/Angular 4 template that ships whith .Net core 2 Sdk.

Using dotnet build or dotnet run it's not generating new dist folder for client side angular project.

I am using visual studio code as editor.

Can i miss any command beacuse of that new build is not generating?

Following is package.json

After you have created the project using dotnet new angular you need to run npm install . After that, everything else should work.

I know that but after changing clientside application new bundle is not generated with dotnet build or dotnet run

GlennSills Over a year ago

Are you looking under wwwroot? It should be created when you do a dotnet run.

So what did you change in the client app? Perhaps if you look in the output when you run the app you'll see a typescript compilation error.

It could be that you need to set ASPNETCORE_ENVIRONMENT variable to development.

So in the command line run this:

set ASPNETCORE_ENVIRONMENT=Development

then when you do dotnet run it will pick up your changes.

Instructions on using multiple environments here: https://learn.microsoft.com/en-us/aspnet/core/fundamentals/environments

follow these two steps.

1) Setting the environment to development

Command line

set ASPNETCORE_ENVIRONMENT=Development

PowerShell

$Env:ASPNETCORE_ENVIRONMENT = "Development"

2)

dotnet run

above command will start core project and also start Hot Module Replacement which is can update changed client angular modules without a full page reload. To start Hot Module Replacement in development fix your code block in Startup.cs as bellow

if (env.IsDevelopment())
{
    app.UseDeveloperExceptionPage();
    app.UseWebpackDevMiddleware(new WebpackDevMiddlewareOptions
        {
            HotModuleReplacement = true,
            HotModuleReplacementEndpoint = "/dist/__webpack_hmr"
        });
} else {
    app.UseExceptionHandler("/Home/Error");
}
