I used to be studying Gabby’s weblog submit concerning the new TypeScript/JavaScript challenge 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 consider apps which might be JavaScript heavy, “entrance finish apps” or TypeScript targeted, it may be complicated as to “the place does .NET slot in?”
It is advisable to think about the obligations of your varied tasks or subsystems and the a number of completely legitimate methods you possibly can construct a website or internet app. Let’s think about 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 perhaps have simply added JavaScript through
- A largely JavaScript/TypeScript frontend app the place the HTML may very well be served from any internet server (node, kestrel, static internet apps, nginx, and so on)
- This app might use Vue or React or Angular however 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 the entire above
- This state of affairs has generally been complicated for ASP.NET builders who might 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 offers a TypeScript NuGet Bundle so you possibly can construct your entire app with MSBuild and VS will do the fitting factor.
NEW: Beginning in Visible Studio 2022, there’s a new JavaScript/TypeScript challenge sort (.esproj) that permits you to create standalone Angular, React, and Vue tasks 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 Initiatives. Visible Studio manages recordsdata for a single software in a Mission. The challenge consists of supply code, assets, and configuration recordsdata. On this case we will 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 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 Mission” there are Standalone templates that remedy Instance 2 above. I will decide 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 need it to be.
Then I will add my ASP.NET Net API backend to the identical resolution, 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 type, use the CLI that’s put in for no matter Frontend Framework, and permit me to decide on what internet server and internet 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 potential!
