I used to be studying Gabby’s weblog publish concerning the new TypeScript/JavaScript challenge expertise in Visible Studio 2022. You must learn the docs on JavaScript and TypeScript in Visible Studio 2022.
For those who’re used to ASP.NET apps when you consider 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 essential think about the tasks of your numerous initiatives or subsystems and the a number of completely legitimate methods you’ll be able to construct a web page or internet app. Let’s think about just some:
- An ASP.NET Net app that renders HTML on the server however makes use of TS/JS
- This may occasionally 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 activity
- Could be complicated as a result of it could actually really feel like your app must ‘construct each the shopper and the server’ from one challenge
- A principally JavaScript/TypeScript frontend app the place the HTML might be served from any internet server (node, kestrel, static internet apps, nginx, and many others)
- This app could use Vue or React or Angular nevertheless it’s not an “ASP.NET app”
- It calls backend Net APIs that could be served by ASP.NET, Azure Capabilities, third social gathering REST APIs, or all the above
- This situation has typically been complicated for ASP.NET builders who could 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 help into VS with a full JavaScript Language Service primarily based on TS. It supplies a TypeScript NuGet Package deal so you’ll be able to construct your entire app with MSBuild and VS will do the proper factor.
NEW: Beginning in Visible Studio 2022, there’s a new JavaScript/TypeScript challenge sort (.esproj) that means that you can 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} Answer comprises a number of Tasks. Visible Studio manages information for a single utility in a Mission. The challenge contains supply code, sources, and configuration information. On this case we will 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 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 clear up Instance 2 above. I am going to choose JavaScript React.
Then I am going to click on “Add integration for Empty ASP.NET Net API. It will give me a frontend with javascript able to name a ASP.NET Net 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 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 challenge system – on this case extra JavaScript targeted than .NET targeted. This one makes use of npm to startup the challenge utilizing their internet growth server and proxyMiddleware to proxy localhost:3000 calls over to the ASP.NET Net API challenge.
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 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 need.
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 attainable!
