I used to be studying Gabby’s weblog submit concerning the new TypeScript/JavaScript undertaking expertise in Visible Studio 2022. You must learn the docs on JavaScript and TypeScript in Visible Studio 2022.
If you happen to’re used to ASP.NET apps when you consider 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 good to take into account the tasks of your varied initiatives or subsystems and the a number of completely legitimate methods you’ll be able to construct a website or net app. Let’s take into account just some:
- An ASP.NET Internet app that renders HTML on the server however makes use of TS/JS
- This may occasionally have a Internet API, Razor Pages, with or with out the MVC sample.
- You perhaps have simply added JavaScript through <script> tags
- Perhaps you added a script minimizer/minifier job
- May be complicated as a result of it will probably really feel like your app must ‘construct each the shopper and the server’ from one undertaking
- A principally JavaScript/TypeScript frontend app the place the HTML could possibly be served from any net server (node, kestrel, static net apps, nginx, and so on)
- This app could use Vue or React or Angular but it surely’s not an “ASP.NET app”
- It calls backend Internet APIs that could be served by ASP.NET, Azure Features, third occasion 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 Bundle so you’ll be able to construct your complete app with MSBuild and VS will do the best factor.
NEW: Beginning in Visible Studio 2022, there’s a new JavaScript/TypeScript undertaking kind (.esproj) that means that you can create standalone Angular, React, and Vue initiatives in Visible Studio.
The .esproj idea is nice for folk acquainted with Visible Studio as we all know {that a} Answer incorporates a number of Tasks. Visible Studio manages information for a single utility in a Venture. The undertaking contains supply code, sources, and configuration information. On this case we will have a .csproj for a backend Internet 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 have been outdated 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 resolve Instance 2 above. I am going to decide 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 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 Internet 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 Internet 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 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 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 herald some TypeScript/JavaScript, comply with this tutorial as a result of that is additionally potential!
