I used to be studying Gabby’s weblog publish in regards to 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.
For those who’re used to ASP.NET apps when you concentrate on apps which might be JavaScript heavy, “entrance finish apps” or TypeScript centered, it may be complicated as to “the place does .NET slot in?”
That you must 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 just some:
- An ASP.NET Internet app that renders HTML on the server however makes use of TS/JS
- This may increasingly have a Internet API, Razor Pages, with or with out the MVC sample.
- You possibly have simply added JavaScript by way of <script> tags
- Perhaps you added a script minimizer/minifier job
- Will be complicated as a result of it could really feel like your app must ‘construct each the consumer and the server’ from one mission
- A principally JavaScript/TypeScript frontend app the place the HTML may very well be served from any internet server (node, kestrel, static internet apps, nginx, and many others)
- This app might use Vue or React or Angular nevertheless it’s not an “ASP.NET app”
- It calls backend Internet APIs that could be served by ASP.NET, Azure Features, third get together REST APIs, or the entire above
- This situation has typically been complicated for ASP.NET builders who might 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 assist 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 entire app with MSBuild and VS will do the correct factor.
NEW: Beginning in Visible Studio 2022, there’s a new JavaScript/TypeScript mission sort (.esproj) that lets you create standalone Angular, React, and Vue tasks in Visible Studio.
The .esproj idea is nice for folk aware of Visible Studio as we all know {that a} Resolution incorporates a number of Tasks. Visible Studio manages recordsdata for a single software in a Mission. The mission consists of supply code, assets, and configuration recordsdata. On this case we will have a .csproj for a backend Internet API and an .esproj that makes use of a consumer aspect 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 downside with Angular CLI, Create React App, and Vue CLI.
If I’m in VS and go “File New Mission” there are Standalone templates that resolve Instance 2 above. I am going to choose JavaScript React.
Then I am going to click on “Add integration for Empty ASP.NET Internet API. This can give me a frontend with javascript able to name a ASP.NET Internet 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 would like it to be.
Then I am going to add my ASP.NET Internet API backend to the identical resolution, 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 centered than .NET centered. This one makes use of npm to startup the mission utilizing their internet growth server and proxyMiddleware to proxy localhost:3000 calls over to the ASP.NET Internet 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 Of us are used to, and that is OK. This exhibits 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 internet server and internet 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!
