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 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.

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

It’s worthwhile to take into account the tasks of your varied initiatives or subsystems and the a number of completely legitimate methods you may construct a web page 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 may increasingly have a Net API, Razor Pages, with or with out the MVC sample.
    • You possibly have simply added JavaScript by way of <script> tags
    • Perhaps you added a script minimizer/minifier activity
    • Will be complicated as a result of it may possibly really feel like your app must ‘construct each the shopper and the server’ from one undertaking
  2. A principally JavaScript/TypeScript frontend app the place the HTML may very well be served from any net server (node, kestrel, static net apps, nginx, and many others)
    • This app could use Vue or React or Angular nevertheless it’s not an “ASP.NET app”
    • It calls backend Net APIs which may be served by ASP.NET, Azure Capabilities, third get together REST APIs, or the entire above
    • This situation has typically been complicated for ASP.NET builders who could 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 supplies a TypeScript NuGet Package deal so you may 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 undertaking kind (.esproj) that means that you can create standalone Angular, React, and Vue initiatives in Visible Studio.

The .esproj idea is nice for folk conversant in Visible Studio as we all know {that a} Resolution comprises a number of Tasks. Visible Studio manages information for a single software in a Undertaking. The undertaking contains supply code, assets, and configuration information. On this case we will 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 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 Net API. It will give me a frontend with javascript able to name a ASP.NET Net API backend. I am going to 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 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 undertaking system – on this case extra JavaScript centered than .NET centered. This one makes use of npm to startup the undertaking utilizing their net improvement server and proxyMiddleware to proxy localhost:3000 calls over to the ASP.NET Net 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 assist both improvement 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 usher in some TypeScript/JavaScript, comply with this tutorial as a result of that is additionally attainable!
