            How to return 404 on wrong API url? (ASP.NET Core + SPA)
            Asked 2019-Aug-14 at 07:23

            I need to return 404 on wrong api call so I can create proper response to user on client side (Angular 5). Currently backend returns status code 200 and index.html, and that results in json parse error on frontend.

            I created new web project with ASP.NET Core 2.1 and Angular template project. Here's the link to published version of that template. I didn't change template code at all, I just published that on azure as it is. (In dev mode I get 404 error as expected).

            As mentioned here default behaviour should be 404.

            Here is the Startup.cs, and here SampleDataController.cs.

            Note: Based on your links, I assume you are using the app.UseSpa() middleware.

            The route middleware is executed in order, and if the request never finds a controller a 404 status is returned. The UseSpa middlware is a catch-all, and any request that gets to that point will always have the default SPA page returned. This means any request to a route that hasn't yet found a controller will always return the default SPA page, and not throw a 404.

            What you will want to do it only call UseSpa() if the route is not prefixed with /api. Which essentially lets any requests that start with/api skip past that point.

            This was probably a caching problem, based on I just installed Node.js+NPM and Webpack.

            What I did was the following:

            1. Made sure to restart my computer
            2. Verify that all dependencies was good: Node.js+NPM installed, Node in PATH, Webpack installed globally
            3. Clean everything in my solution
            4. Rebuild in Visual Studio

            It suddenly started working in my end after a couple of times, so pretty sure it's some local cache that caused the problem from not having the dependencies in order.

            Another trick I tried was to pull an earlier version of the application from my repo, which seemed to "refresh" the cache (or whatever was the problem). After going back to an earlier version and then back to the newest, things just worked.

            .Net Core 2 SPA/Angular Template - Render Global CSS
            Asked 2019-Apr-14 at 13:22

            I am very new to Webpack and the .NET Core 2 Angular SPA Template. I'm trying to create a global stylesheet for the entire site. I could reference that style in the Layout view to render it in the main view, but then I lose the benefits of the pre-render engine and bundling with WebPack (as well as minification).

            The Webpack documentation says that in order to include static CSS that you need to add a require(../filepath) to your module, but I don't see a way to do this in the boot.browser.ts.

            I'm still just getting started with .NET core so my site is basically just the OOB .Net Core 2 template with Angular. I'm keeping my global styles sheet in ClientApp/Styles/Global.css at the moment. Thanks for your time.

            As in visual studio 2019 Angular template with ASP.Net Core 2.2 you don't have to manage webpack file like old version. I'm assume that you are using Angular 5 with webpack template.

            Create ASP.Net Core app like this

            Then you will see style.css in your angular app. That is where you put your global style

            Hope it will help you. Best regards.

            How to change PublicPath for Create React App in Dev Environment
            Asked 2019-Feb-07 at 16:02

            I am using Microsoft.DotNet.Web.Spa.ProjectTemplates::2.0.0-rc1-final which internally uses Create-react-app and AspnetCore.ReactDevelopmentServer

            My Dev. Environment is using IIS for hosting multiple api's say api1 as http://localhost/api1 and api2 as http://localhost/api2

            Problem is if I host my React app from Microsoft.DotNet.Web.Spa.ProjectTemplates::2.0.0-rc1-final template to http://localhost/myApp - it expects the files are always served with PublicPath "/" and hence does not work.

            I know Create-react-app's Prod setup uses PublicPath from PUBLIC_URL or Homepage from package.json.

            Server Side Rendering Vue with ASP.NET Core 2
            Asked 2018-Jun-11 at 20:03

            I'm trying to understand the usage and limitations of server side rendering with vuejs when using aspnet core.

            I used this starter kit for aspnet core and vuejs to setup a simple vue site, which is running based on the code here: https://github.com/selaromdotnet/aspnet-vue-ssr-test/tree/master

            I then modified the project to update the aspnet-prerendering and added vue-server-renderer, compiling a hodgepodge of sources to cobble together this update: https://github.com/selaromdotnet/aspnet-vue-ssr-test/tree/ssr

            If I run this project, the site appears to load fine, and if I turn off the javascript in the browser, I can see that it does appear that the server-side rendering executed and populated the html result:

            however, because JavaScript is disabled, the content isn't moved into the dom as it looks like it is trying to...

            My understanding of server-side rendering is that it would populate the html entirely and serve a completed page to the user, so that even if JS was disabled, they'd at least be able to see the page (specifically for SEO purposes). Am I incorrect?

            Now I believe modern search engines will execute simple scripts like this to get the content, but I still don't want a blank page rendered if js is disabled...

            Is this a limitation of server-side rendering, or perhaps specifically ssr with vue and/or aspnet core?

            or am I just missing a step somewhere?

            Edit: more information

            I looked at the source code for what I believe is the method that prerenders the section here: https://github.com/aspnet/JavaScriptServices/blob/dev/src/Microsoft.AspNetCore.SpaServices/Prerendering/PrerenderTagHelper.cs

            As you correctly noticed, for your project, result.Html inside the tag helper is null. So that line cannot be the location where the output is being generated. Since the HTML output from your prerendering script also does not include a script tag, it is clear that something has to generate that. The only other line that could possible do this is the following from the PrerenderTagHelper:

            No NgModule metadata found for 'AppModule' Error in Angular 5 server-side rendering with --env.prod
            Asked 2018-Apr-27 at 00:39

            I'm trying to upgrade an ASP.NET Core + Angular 4 SPA project from .NET Core 2.0.0/Angular4 to .NET Core 2.0.3/Angular5. I managed to get everything working properly except for the server-side rendering in a production environment, i/e when I publish the app:

            An unhandled exception has occurred: No NgModule metadata found for 'AppModule'.
            Error: No NgModule metadata found for 'AppModule'.

            The issue only happens when both of these two conditions are met:

            • Webpack builds the packages using the --env.prod switch
            • The Index.cshtml view file contains the asp-prerender-module parameter, just like in the following example:

              Loading...

            If I remove the switch and/or the parameter, the problem disappears (together with SSR).

            There's a bunch of other info I can give:

            • It's not something related to IIS, it happens at Kestrel-level.
            • It's not related to the web server machine because I can even reproduce it with locally by manually launching Webpack with the --end.prod switch right before a Debug or Release run.
            • It doesn't seem to have anything to do with the source code, as I can reproduce it even with a single-component sample app with very basic AppModule files and trivial code.
            • The project was running perfectly fine with .NET Core 2.0.0 and Angular 4.3.x.
            • The only major thing I changed in the webpack.config.js file is replacing the AotPlugin with the new, Angular5-specific AngularCompilerPlugin provided by the @ngtools/webpack package: I think that might as well be the cause, as the --env.prod switch makes use of that AOT compiler instead of the JIT one. That, or something related to the .NET SpaServices package - maybe not on-par with the new Angular5 and/or the new AoT compiler?

            Sadly, I can't revert to the former AotPlugin because it throws errors as well - which is perfectly understandable, as it's not meant to be used with Angular5.
