I used to be studying Gabby’s weblog submit concerning the new TypeScript/JavaScript mission 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 concentrate on apps which are 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 possibly can construct a site or net app. Let’s take into account just some:
- An ASP.NET Net app that renders HTML on the server however makes use of TS/JS
- This may increasingly have a Net API, Razor Pages, with or with out the MVC sample.
- You possibly have simply added JavaScript by way of <script> tags
- Possibly you added a script minimizer/minifier job
- Might be complicated as a result of it might really feel like your app must ‘construct each the shopper and the server’ from one mission
- 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 on)
- This app could use Vue or React or Angular however it’s not an “ASP.NET app”
- It calls backend Net APIs which may be served by ASP.NET, Azure Capabilities, third social gathering 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 help into VS with a full JavaScript Language Service based mostly on TS. It gives a TypeScript NuGet Package deal so you possibly can construct your complete app with MSBuild and VS will do the fitting factor.
NEW: Beginning in Visible Studio 2022, there’s a new JavaScript/TypeScript mission sort (.esproj) that permits you to create standalone Angular, React, and Vue initiatives in Visible Studio.
The .esproj idea is nice for people conversant in Visible Studio as we all know {that a} Answer comprises a number of Tasks. Visible Studio manages information for a single utility in a Undertaking. The mission consists of supply code, sources, 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 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 drawback with Angular CLI, Create React App, and Vue CLI.
If I’m in VS and go “File New Undertaking” there are Standalone templates that clear up 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 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 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 mission system – on this case extra JavaScript targeted than .NET targeted. This one makes use of npm to startup the mission utilizing their net growth server and proxyMiddleware to proxy localhost:3000 calls over to the ASP.NET Net API mission.
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 help both growth type, use the CLI that’s put in for no matter Frontend Framework, and permit me to decide on what net server and net 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 potential!
