I used to be studying Gabby’s weblog put up concerning the new TypeScript/JavaScript undertaking expertise in Visible Studio 2022. You must 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 are JavaScript heavy, “entrance finish apps” or TypeScript targeted, it may be complicated as to “the place does .NET slot in?”
You might want to contemplate the tasks of your numerous tasks or subsystems and the a number of completely legitimate methods you possibly can construct a web page or net app. Let’s contemplate 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 perhaps have simply added JavaScript by way of <script> tags
- Possibly you added a script minimizer/minifier activity
- Might be complicated as a result of it could really feel like your app must ‘construct each the consumer 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 on)
- This app might 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 Features, third get together REST APIs, or the entire above
- This situation 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 assist into VS with a full JavaScript Language Service primarily based on TS. It gives a TypeScript NuGet Bundle so you possibly can construct your entire app with MSBuild and VS will do the precise factor.
NEW: Beginning in Visible Studio 2022, there’s a new JavaScript/TypeScript undertaking sort (.esproj) that permits you to create standalone Angular, React, and Vue tasks in Visible Studio.
The .esproj idea is nice for folk acquainted with Visible Studio as we all know {that a} Resolution comprises a number of Tasks. Visible Studio manages information for a single utility in a Challenge. The undertaking 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 consumer facet 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 downside with Angular CLI, Create React App, and Vue CLI.
If I’m in VS and go “File New Challenge” 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 would like 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 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 (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 doable!
