I used to be studying Gabby’s weblog publish concerning the new TypeScript/JavaScript venture expertise in Visible Studio 2022. You must 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 might be JavaScript heavy, “entrance finish apps” or TypeScript targeted, it may be complicated as to “the place does .NET slot in?”
You’ll want to contemplate the obligations of your varied initiatives or subsystems and the a number of completely legitimate methods you possibly can construct a website online or net app. Let’s contemplate just some:
- An ASP.NET Internet app that renders HTML on the server however makes use of TS/JS
- This may increasingly have a Internet API, Razor Pages, with or with out the MVC sample.
- You possibly have simply added JavaScript through
- A largely JavaScript/TypeScript frontend app the place the HTML may very well be served from any net server (node, kestrel, static net apps, nginx, and so forth)
- This app might use Vue or React or Angular however it’s not an “ASP.NET app”
- It calls backend Internet APIs that could be served by ASP.NET, Azure Capabilities, third occasion REST APIs, or the entire above
- This situation has generally been complicated for ASP.NET builders who might 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 offers a TypeScript NuGet Bundle so you possibly can construct your complete 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 lets you create standalone Angular, React, and Vue initiatives in Visible Studio.
The .esproj idea is nice for folk accustomed to Visible Studio as we all know {that a} Answer incorporates a number of Initiatives. Visible Studio manages recordsdata for a single utility in a Challenge. 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 shopper facet 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 downside with Angular CLI, Create React App, and Vue CLI.
If I’m in VS and go “File New Challenge” 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 need 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 targeted than .NET targeted. This one makes use of npm to startup the venture utilizing their net 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 People are used to, and that is OK. This reveals me that Visible Studio 2022 can assist both growth fashion, use the CLI that’s put in for no matter Frontend Framework, and permit me to decide on what net server and net browser (through Launch.json) I need.
If you wish to flip it, and put ASP.NET Core as the first after which usher in some TypeScript/JavaScript, observe this tutorial as a result of that is additionally attainable!
