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 concerning the new TypeScript/JavaScript venture expertise in Visible Studio 2022. You must learn the docs on JavaScript and TypeScript in Visible Studio 2022.

    Should 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 think about the duties of your varied initiatives or subsystems and the a number of completely legitimate methods you may construct a site 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 will have a Internet 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
      • May be complicated as a result of it could actually really feel like your app must ‘construct each the consumer and the server’ from one venture
    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 many others)
      • This app could use Vue or React or Angular but it surely’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 all the above
      • This situation has generally 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 primarily based on TS. It supplies a TypeScript NuGet Package deal so you may 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 sort (.esproj) that permits you to create standalone Angular, React, and Vue initiatives in Visible Studio.

    The .esproj idea is nice for people acquainted with Visible Studio as we all know {that a} Answer accommodates a number of Tasks. Visible Studio manages recordsdata for a single utility in a Mission. The venture consists of supply code, assets, and configuration recordsdata. On this case we are able to 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 Mission” there are Standalone templates that clear up 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 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 would like it to be.

    Then I will add my ASP.NET Internet API backend to the identical resolution, 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 internet improvement 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 Of us are used to, and that is OK. This exhibits 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 internet server and internet 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 herald some TypeScript/JavaScript, observe this tutorial as a result of that is additionally doable!
