JavaScript and TypeScript Tasks with React, Angular, or Vue in Visible Studio 2022 with or with out .NET



I used to be studying Gabby’s weblog submit concerning the new TypeScript/JavaScript venture expertise in Visible Studio 2022. You need to learn the docs on JavaScript and TypeScript in Visible Studio 2022.

If you happen to’re used to ASP.NET apps when you concentrate on apps which might be JavaScript heavy, “entrance finish apps” or TypeScript targeted, it may be complicated as to “the place does .NET slot in?”

You must think about the duties of your varied initiatives or subsystems and the a number of completely legitimate methods you possibly can construct a website online or net app. Let’s think about only a few:

  1. An ASP.NET Internet app that renders HTML on the server however makes use of TS/JS
    • This will likely have a Internet API, Razor Pages, with or with out the MVC sample.
    • You perhaps have simply added JavaScript by way of <script> tags
    • Possibly you added a script minimizer/minifier activity
    • Will be complicated as a result of it might probably really feel like your app must ‘construct each the consumer and the server’ from one venture
  2. A largely JavaScript/TypeScript frontend app the place the HTML could possibly be served from any net server (node, kestrel, static net apps, nginx, and many others)
    • This app might use Vue or React or Angular however it’s not an “ASP.NET app”
    • It calls backend Internet APIs which may be served by ASP.NET, Azure Features, third celebration REST APIs, or the entire above
    • This state of affairs has generally been complicated for ASP.NET builders who might get confused about accountability. Who builds what, the place do issues find yourself, how do I construct and deploy this?

VS2022 brings JavaScript and TypeScript help into VS with a full JavaScript Language Service based mostly on TS. It gives a TypeScript NuGet Package deal so you possibly can construct your complete app with MSBuild and VS will do the correct factor.

NEW: Beginning in Visible Studio 2022, there’s a new JavaScript/TypeScript venture kind (.esproj) that means that you can create standalone Angular, React, and Vue initiatives in Visible Studio.

The .esproj idea is nice for people conversant in Visible Studio as we all know {that a} Answer incorporates a number of Tasks. Visible Studio manages recordsdata for a single software in a Undertaking. The venture contains supply code, assets, and configuration recordsdata. On this case we are able to have a .csproj for a backend Internet API and an .esproj that makes use of a consumer facet template like Angular, React, or Vue.

Factor is, traditionally when Visible Studio supported Angular, React, or Vue, it is templates had been outdated and never up to date sufficient. VS2022 makes use of the native CLIs for these entrance ends, fixing that downside with Angular CLI, Create React App, and Vue CLI.

If I’m in VS and go “File New Undertaking” there are Standalone templates that remedy Instance 2 above. I am going to decide JavaScript React.

Then I am going to click on “Add integration for Empty ASP.NET Internet API. It will give me a frontend with javascript able to name a ASP.NET Internet API backend. I am going to observe alongside right here.

It then makes use of the React CLI to make the entrance finish, which once more, is cool because it’s no matter model I would like it to be.

Then I am going to add my ASP.NET Internet API backend to the identical answer, so now I’ve an esproj and a csproj like this

Now I’ve a pleasant clear two venture system – on this case extra JavaScript targeted than .NET targeted. This one makes use of npm to startup the venture utilizing their net growth server and proxyMiddleware to proxy localhost:3000 calls over to the ASP.NET Internet API venture.

Here’s a React app served by npm calling over to the Climate service served from Kestrel on ASP.NET.

That is inverted than most ASP.NET People are used to, and that is OK. This exhibits me that Visible Studio 2022 can help both growth model, use the CLI that’s put in for no matter Frontend Framework, and permit me to decide on what net server and net browser (by way of Launch.json) I would like.

If you wish to flip it, and put ASP.NET Core as the first after which herald some TypeScript/JavaScript, observe this tutorial as a result of that is additionally potential!
