I used to be studying Gabby’s weblog submit in regards to the new TypeScript/JavaScript undertaking expertise in Visible Studio 2022. You need to learn the docs on JavaScript and TypeScript in Visible Studio 2022.
For those who’re used to ASP.NET apps when you concentrate on 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 think about the obligations of your varied tasks or subsystems and the a number of completely legitimate methods you possibly can construct a website online or net 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 through <script> tags
- Possibly you added a script minimizer/minifier process
- May be complicated as a result of it might really feel like your app must ‘construct each the shopper and the server’ from one undertaking
- A largely JavaScript/TypeScript frontend app the place the HTML may very well be served from any net server (node, kestrel, static net apps, nginx, and so on)
- 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 Features, third get together REST APIs, or the entire 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 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 best factor.
NEW: Beginning in Visible Studio 2022, there’s a new JavaScript/TypeScript undertaking sort (.esproj) that lets you 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 Tasks. Visible Studio manages information for a single utility in a Challenge. The undertaking contains supply code, assets, 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 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 Challenge” 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 can give me a frontend with javascript able to name a ASP.NET Net API backend. I will 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 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 undertaking system – on this case extra JavaScript targeted than .NET targeted. This one makes use of npm to startup the undertaking utilizing their net improvement 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 exhibits me that Visible Studio 2022 can help both improvement 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 (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, comply with this tutorial as a result of that is additionally potential!
