I used to be studying Gabby’s weblog publish concerning the new TypeScript/JavaScript undertaking 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 can be JavaScript heavy, “entrance finish apps” or TypeScript targeted, it may be complicated as to “the place does .NET slot in?”
It’s essential to contemplate the duties of your numerous initiatives or subsystems and the a number of completely legitimate methods you may construct a website online or net app. Let’s contemplate only a few:
- 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 possibly have simply added JavaScript through <script> tags
- Perhaps you added a script minimizer/minifier job
- Will be complicated as a result of it may really feel like your app must ‘construct each the shopper and the server’ from one undertaking
- A largely JavaScript/TypeScript frontend app the place the HTML could possibly be served from any net server (node, kestrel, static net 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 Capabilities, third get together REST APIs, or all the above
- This situation has typically 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 offers a TypeScript NuGet Bundle so you may 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 undertaking kind (.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} Resolution incorporates a number of Initiatives. Visible Studio manages information for a single software in a Mission. The undertaking contains supply code, assets, and configuration information. 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 Mission” there are Standalone templates that resolve Instance 2 above. I will choose JavaScript React.
Then I will click on “Add integration for Empty ASP.NET Net API. This can give me a frontend with javascript able to name a ASP.NET Net 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 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 undertaking system – on this case extra JavaScript targeted than .NET targeted. This one makes use of npm to startup the undertaking utilizing their net growth server and proxyMiddleware to proxy localhost:3000 calls over to the ASP.NET Net API undertaking.
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 doable!
