I used to be studying Gabby’s weblog submit concerning the new TypeScript/JavaScript venture expertise in Visible Studio 2022. You must learn the docs on JavaScript and TypeScript in Visible Studio 2022.
If you happen to’re used to ASP.NET apps when you consider apps which can be JavaScript heavy, “entrance finish apps” or TypeScript centered, it may be complicated as to “the place does .NET slot in?”
You must think about the duties of your varied tasks or subsystems and the a number of completely legitimate methods you may construct a website online or internet app. Let’s think about 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 perhaps have simply added JavaScript through <script> tags
- Perhaps you added a script minimizer/minifier activity
- Might be complicated as a result of it may well really feel like your app must ‘construct each the consumer and the server’ from one venture
- A largely 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 might 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 Capabilities, third get together 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 based mostly on TS. It supplies a TypeScript NuGet Bundle so you may construct your complete app with MSBuild and VS will do the suitable factor.
NEW: Beginning in Visible Studio 2022, there’s a new JavaScript/TypeScript venture sort (.esproj) that lets you create standalone Angular, React, and Vue tasks in Visible Studio.
The .esproj idea is nice for folk acquainted with Visible Studio as we all know {that a} Resolution accommodates a number of Initiatives. Visible Studio manages information for a single software in a Mission. The venture consists of supply code, sources, and configuration information. On this case we will 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 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 am going to decide JavaScript React.
Then I am going to click on “Add integration for Empty ASP.NET Net API. This may 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 need 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 venture system – on this case extra JavaScript centered than .NET centered. This one makes use of npm to startup the venture utilizing their internet growth server and proxyMiddleware to proxy localhost:3000 calls over to the ASP.NET Net API venture.
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 reveals me that Visible Studio 2022 can help 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 (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, comply with this tutorial as a result of that is additionally doable!
