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







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

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

It’s essential to take into account the duties of your varied tasks or subsystems and the a number of completely legitimate methods you possibly can construct a site or net app. Let’s take into account only a few:

  1. An ASP.NET Net app that renders HTML on the server however makes use of TS/JS
    • This will have a Net API, Razor Pages, with or with out the MVC sample.
    • You possibly have simply added JavaScript through <script> tags
    • Possibly you added a script minimizer/minifier job
    • May be complicated as a result of it could really feel like your app must ‘construct each the shopper and the server’ from one venture
  2. A largely JavaScript/TypeScript frontend app the place the HTML may very well be served from any net server (node, kestrel, static net apps, nginx, and so on)
    • This app might use Vue or React or Angular nevertheless it’s not an “ASP.NET app”
    • It calls backend Net APIs that could be served by ASP.NET, Azure Features, third social gathering REST APIs, or the entire above
    • This state of affairs has generally 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 assist into VS with a full JavaScript Language Service based mostly on TS. It gives a TypeScript NuGet Bundle so you possibly can construct your complete app with MSBuild and VS will do the appropriate factor.

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

The .esproj idea is nice for people acquainted with Visible Studio as we all know {that a} Resolution comprises a number of Initiatives. Visible Studio manages recordsdata for a single software in a Venture. The venture contains supply code, sources, and configuration recordsdata. On this case we are able to have a .csproj for a backend Net API and an .esproj that makes use of a shopper aspect 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 Venture” there are Standalone templates that resolve Instance 2 above. I am going to choose JavaScript React.

Then I am going to click on “Add integration for Empty ASP.NET Net API. This can give me a frontend with javascript able to name a ASP.NET Net 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 need it to be.

Then I am going to add my ASP.NET Net 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 improvement server and proxyMiddleware to proxy localhost:3000 calls over to the ASP.NET Net 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 reveals me that Visible Studio 2022 can assist both improvement fashion, use the CLI that’s put in for no matter Frontend Framework, and permit me to decide on what net server and net browser (through Launch.json) I need.

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 attainable!
