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 mission expertise in Visible Studio 2022. You must learn the docs on JavaScript and TypeScript in Visible Studio 2022.

In the event 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?”

It’s essential to contemplate the tasks of your numerous tasks or subsystems and the a number of completely legitimate methods you’ll be able to construct a website online or internet app. Let’s contemplate just some:

  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 could really feel like your app must ‘construct each the consumer and the server’ from one mission
  2. A largely JavaScript/TypeScript frontend app the place the HTML could possibly be served from any internet server (node, kestrel, static internet apps, nginx, and so on)
    • 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 Features, third get together REST APIs, or the entire above
    • This situation 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 Package deal so you’ll be able to construct your entire app with MSBuild and VS will do the precise factor.

NEW: Beginning in Visible Studio 2022, there’s a new JavaScript/TypeScript mission kind (.esproj) that lets you 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 comprises a number of Tasks. Visible Studio manages recordsdata for a single software in a Undertaking. The mission contains supply code, sources, and configuration recordsdata. On this case we will have a .csproj for a backend Internet API and an .esproj that makes use of a consumer aspect template like Angular, React, or Vue.

Factor is, traditionally when Visible Studio supported Angular, React, or Vue, it is templates have been outdated 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 remedy Instance 2 above. I will decide JavaScript React.

Then I will 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 will 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.

React Create CLI

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 mission system – on this case extra JavaScript centered than .NET centered. This one makes use of npm to startup the mission utilizing their internet improvement server and proxyMiddleware to proxy localhost:3000 calls over to the ASP.NET Internet API mission.

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 exhibits 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 internet server and internet browser (by way of 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 doable!
