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. It is best to learn the docs on JavaScript and TypeScript in Visible Studio 2022.

When 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?”

That you must take into account the obligations of your varied tasks or subsystems and the a number of completely legitimate methods you’ll be able to construct a website or internet app. Let’s take into account just some:

  1. An ASP.NET Net app that renders HTML on the server however makes use of TS/JS
    • This will likely have a Net API, Razor Pages, with or with out the MVC sample.
    • You perhaps have simply added JavaScript by way of <script> tags
    • Perhaps you added a script minimizer/minifier job
    • Might be complicated as a result of it will probably really feel like your app must ‘construct each the consumer and the server’ from one venture
  2. A principally JavaScript/TypeScript frontend app the place the HTML might be served from any internet server (node, kestrel, static internet apps, nginx, and so forth)
    • This app could 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 celebration REST APIs, or all the above
    • This state of affairs 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 Package deal so you’ll be able to construct your entire app with MSBuild and VS will do the correct factor.

NEW: Beginning in Visible Studio 2022, there’s a new JavaScript/TypeScript venture kind (.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} Answer comprises a number of Tasks. Visible Studio manages recordsdata for a single software in a Challenge. The venture contains supply code, sources, and configuration recordsdata. On this case we will have a .csproj for a backend Net 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 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 Challenge” there are Standalone templates that clear up 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 may 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 need it to be.

Then I am going to add my ASP.NET Net 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 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 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 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, comply with this tutorial as a result of that is additionally potential!
