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. It is best 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 centered, it may be complicated as to “the place does .NET slot in?”

You might want 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 website or net app. Let’s take into account 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 job
    • Could be complicated as a result of it could possibly 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 might be served from any net server (node, kestrel, static net apps, nginx, and so on)
    • This app could 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 occasion REST APIs, or the entire above
    • This situation has generally been complicated for ASP.NET builders who could 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 assist into VS with a full JavaScript Language Service primarily based on TS. It gives a TypeScript NuGet Bundle so you possibly can construct your complete app with MSBuild and VS will do the best factor.

NEW: Beginning in Visible Studio 2022, there’s a new JavaScript/TypeScript venture sort (.esproj) that permits you to 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 incorporates a number of Initiatives. Visible Studio manages recordsdata for a single software in a Venture. The venture consists of supply code, assets, and configuration recordsdata. On this case we will have a .csproj for a backend Internet 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 have been old-fashioned 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 Venture” there are Standalone templates that resolve 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 need it to be.

React Create CLI

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 centered than .NET centered. 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 assist 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 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 potential!
