I used to be studying Gabby’s weblog submit 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.
Should you’re used to ASP.NET apps when you consider apps which are JavaScript heavy, “entrance finish apps” or TypeScript targeted, it may be complicated as to “the place does .NET slot in?”
It’s essential to think about the tasks of your varied initiatives or subsystems and the a number of completely legitimate methods you possibly can construct a web page or net app. Let’s think about only a few:
- 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 perhaps have simply added JavaScript through
- A largely JavaScript/TypeScript frontend app the place the HTML might be served from any net server (node, kestrel, static net apps, nginx, and many others)
- This app could use Vue or React or Angular however it’s not an “ASP.NET app”
- It calls backend Net APIs that could be served by ASP.NET, Azure Features, third celebration REST APIs, or the entire above
- This situation 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 assist into VS with a full JavaScript Language Service primarily based on TS. It offers a TypeScript NuGet Package deal so you possibly can construct your complete 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 initiatives in Visible Studio.
The .esproj idea is nice for people aware of Visible Studio as we all know {that a} Answer comprises a number of Tasks. Visible Studio manages recordsdata for a single utility in a Challenge. The mission contains supply code, assets, 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 shopper 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 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. This can give me a frontend with javascript able to name a ASP.NET Net API backend. I am going to 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 am going to 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 mission system – on this case extra JavaScript targeted than .NET targeted. This one makes use of npm to startup the mission utilizing their net improvement server and proxyMiddleware to proxy localhost:3000 calls over to the ASP.NET Net 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 People are used to, and that is OK. This exhibits me that Visible Studio 2022 can assist 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 would like.
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 attainable!
