I used to be studying Gabby’s weblog submit concerning the new TypeScript/JavaScript mission expertise in Visible Studio 2022. You must learn the docs on JavaScript and TypeScript in Visible Studio 2022.
Should you’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?”
It is advisable contemplate the tasks of your numerous tasks or subsystems and the a number of completely legitimate methods you’ll be able to construct a web page 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 will have a Internet 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 activity
- Might be complicated as a result of it will possibly really feel like your app must ‘construct each the shopper and the server’ from one mission
- A principally 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 might use Vue or React or Angular but it surely’s not an “ASP.NET app”
- It calls backend Internet APIs that could be served by ASP.NET, Azure Features, third celebration REST APIs, or the entire above
- This situation has typically 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 primarily based on TS. It gives a TypeScript NuGet Package deal so you’ll be able to 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 mission kind (.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} Answer incorporates a number of Initiatives. Visible Studio manages information for a single utility in a Undertaking. The mission consists of supply code, sources, and configuration information. On this case we are able to 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 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 Undertaking” there are Standalone templates that clear up 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. It will 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 need 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 improvement 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 reveals 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 (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!
