I used to be studying Gabby’s weblog publish in regards to the new TypeScript/JavaScript venture 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 consider apps which might be JavaScript heavy, “entrance finish apps” or TypeScript targeted, it may be complicated as to “the place does .NET slot in?”
You want to take into account the duties of your numerous tasks or subsystems and the a number of completely legitimate methods you may construct a website or internet app. Let’s take into account only a few:
- An ASP.NET Net app that renders HTML on the server however makes use of TS/JS
- This may occasionally 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
- May be complicated as a result of it could actually really feel like your app must ‘construct each the shopper and the server’ from one venture
- 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 forth)
- 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 Features, third social gathering REST APIs, or the entire 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 help into VS with a full JavaScript Language Service primarily based on TS. It offers a TypeScript NuGet Bundle so you may 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 sort (.esproj) that means that you can 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 accommodates a number of Initiatives. Visible Studio manages recordsdata for a single software in a Venture. The venture consists of supply code, sources, and configuration recordsdata. On this case we are able to 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 drawback with Angular CLI, Create React App, and Vue CLI.
If I’m in VS and go “File New Venture” there are Standalone templates that remedy Instance 2 above. I will choose JavaScript React.
Then I will 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 will 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 will 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 venture system – on this case extra JavaScript targeted than .NET targeted. This one makes use of npm to startup the venture utilizing their internet growth 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 People are used to, and that is OK. This exhibits me that Visible Studio 2022 can help both growth 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!
