I used to be studying Gabby’s weblog publish 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.
In case 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 must contemplate the obligations of your numerous tasks or subsystems and the a number of completely legitimate methods you’ll be able to construct a web page or internet app. Let’s contemplate just some:
- 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
- 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 Internet APIs which may be served by ASP.NET, Azure Capabilities, third get together REST APIs, or all the 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’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 lets you create standalone Angular, React, and Vue tasks in Visible Studio.
The .esproj idea is nice for people acquainted with Visible Studio as we all know {that a} Resolution comprises a number of Tasks. Visible Studio manages recordsdata for a single utility in a Undertaking. The venture contains supply code, sources, and configuration recordsdata. On this case we will 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Factor is, traditionally when Visible Studio supported Angular, React, or Vue, it is templates had been outdated and never up to date sufficient.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 choose JavaScript React.
Then I am going to click on “Add integration for Empty ASP.NET Internet API. This can 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 would like it to be.
Then I am going to 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 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 Of us are used to, and that is OK. This reveals 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 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!
