I used to be studying Gabby’s weblog put up 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 might be JavaScript heavy, “entrance finish apps” or TypeScript targeted, it may be complicated as to “the place does .NET slot in?”
You should contemplate the duties of your varied tasks or subsystems and the a number of completely legitimate methods you’ll be able to construct a website or internet app. Let’s contemplate 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 perhaps have simply added JavaScript by way of <script> tags
- Perhaps you added a script minimizer/minifier activity
- Will be complicated as a result of it may 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 could possibly be served from any internet server (node, kestrel, static internet apps, nginx, and so forth)
- This app could use Vue or React or Angular however it’s not an “ASP.NET app”
- It calls backend Internet APIs which may be served by ASP.NET, Azure Capabilities, third get together REST APIs, or all the above
- This situation has generally 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 based mostly on TS. It gives a TypeScript NuGet Bundle so you’ll be able to construct your entire 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 permits you to create standalone Angular, React, and Vue tasks in Visible Studio.
The .esproj idea is nice for people aware of Visible Studio as we all know {that a} Resolution comprises a number of Initiatives. Visible Studio manages information for a single software in a Mission. The undertaking contains supply code, assets, and configuration information. On this case we will have a .csproj for a backend Internet 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 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 Mission” there are Standalone templates that remedy Instance 2 above. I will choose JavaScript React.
Then I will click on “Add integration for Empty ASP.NET Internet API. It will give me a frontend with javascript able to name a ASP.NET Internet 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 would like it to be.
Then I will add my ASP.NET Internet 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 internet improvement server and proxyMiddleware to proxy localhost:3000 calls over to the ASP.NET Internet 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 Of us 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 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, comply with this tutorial as a result of that is additionally doable!
