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 put up in regards to the new TypeScript/JavaScript undertaking expertise in Visible Studio 2022. It is best to learn the docs on JavaScript and TypeScript in Visible Studio 2022.

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

You want to think about the tasks of your numerous tasks or subsystems and the a number of completely legitimate methods you’ll be able to construct a web page or internet app. Let’s think about just some:

  1. An ASP.NET Internet app that renders HTML on the server however makes use of TS/JS
    • This may increasingly have a Internet API, Razor Pages, with or with out the MVC sample.
    • You possibly have simply added JavaScript through <script> tags
    • Perhaps you added a script minimizer/minifier activity
    • Could be complicated as a result of it could actually really feel like your app must ‘construct each the consumer and the server’ from one undertaking
  2. A largely JavaScript/TypeScript frontend app the place the HTML may very well be served from any internet server (node, kestrel, static internet 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 that could be served by ASP.NET, Azure Capabilities, third celebration REST APIs, or the entire above
    • This state of affairs has typically been complicated for ASP.NET builders who might get confused about duty. 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 primarily based on TS. It supplies a TypeScript NuGet Package deal so you’ll be able to construct your entire app with MSBuild and VS will do the correct factor.

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

The .esproj idea is nice for folk accustomed to Visible Studio as we all know {that a} Resolution accommodates a number of Tasks. Visible Studio manages information for a single utility in a Undertaking. The undertaking contains supply code, assets, and configuration information. 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 old-fashioned and never up to date sufficient. VS2022 makes use of the native CLIs for these entrance ends, fixing that drawback with Angular CLI, Create React App, and Vue CLI.

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

Then I will click on “Add integration for Empty ASP.NET Internet API. This may give me a frontend with javascript able to name a ASP.NET Internet API backend. I will comply with 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 will 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 undertaking system – on this case extra JavaScript centered than .NET centered. This one makes use of npm to startup the undertaking utilizing their internet improvement server and proxyMiddleware to proxy localhost:3000 calls over to the ASP.NET Internet API undertaking.

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 Of us are used to, and that is OK. This reveals me that Visible Studio 2022 can help both improvement model, use the CLI that’s put in for no matter Frontend Framework, and permit me to decide on what internet server and internet browser (through 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, comply with this tutorial as a result of that is additionally doable!
