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.
If you happen to’re used to ASP.NET apps when you concentrate on apps which are JavaScript heavy, “entrance finish apps” or TypeScript centered, it may be complicated as to “the place does .NET slot in?”
You should contemplate the obligations of your varied initiatives or subsystems and the a number of completely legitimate methods you may construct a web page or internet app. Let’s contemplate just some:
- An ASP.NET Net app that renders HTML on the server however makes use of TS/JS
- This will have a Net API, Razor Pages, with or with out the MVC sample.
- You possibly have simply added JavaScript by way of <script> tags
- Possibly you added a script minimizer/minifier activity
- Could be complicated as a result of it will possibly really feel like your app must ‘construct each the consumer and the server’ from one undertaking
- 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 so on)
- This app could use Vue or React or Angular but it surely’s not an “ASP.NET app”
- It calls backend Net APIs which may be served by ASP.NET, Azure Capabilities, 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 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 primarily based on TS. It gives a TypeScript NuGet Bundle so you may construct your entire app with MSBuild and VS will do the appropriate 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 initiatives in Visible Studio.
The .esproj idea is nice for people accustomed to Visible Studio as we all know {that a} Answer accommodates a number of Initiatives. Visible Studio manages recordsdata for a single utility in a Challenge. The undertaking consists of supply code, sources, and configuration recordsdata. On this case we are able to have a .csproj for a backend Net 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 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 remedy Instance 2 above. I am going to decide JavaScript React.
Then I am going to click on “Add integration for Empty ASP.NET Net API. It will give me a frontend with javascript able to name a ASP.NET Net 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 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 centered than .NET centered. This one makes use of npm to startup the undertaking utilizing their internet 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 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 usher in some TypeScript/JavaScript, observe this tutorial as a result of that is additionally attainable!
