A popular alternative development environment to our preferred JetBrains Rider IDE is to use Visual Studio, the primary issue with this is that VS Code is a better IDE with richer support for npm projects whilst Visual Studio is a better IDE for C# Projects.

Essentially this is why we recommend Rider where it’s best at both, where both C# and npm TypeScript projects can be developed from within the same solution.

Developing with just VS Code

If you prefer the dev UX of a lightweight text editor or your C# project isn’t large, than VS Code on its own can provide a great development UX which is also what Vue recommends themselves, to be used together with the Volar extension.

VSCode’s Integrated Terminal has great multi-terminal support you can toggle between the editor and terminal with Ctrl+ or open a new Terminal Window with Ctrl+Shift+` to run the /ui dev server with:

$ npm run dev

Then in a new Terminal Window, start a new watched C# .NET Server build with:

$ dotnet watch

With both projects started you can open and leave a browser tab running at http://localhost:3000 where it will automatically reload itself at every Ctrl+S save point.

When you’re ready to preview a development build of the Client UI in your .NET App, run:

$ npm run build:local

Which will publish your Vue 3’s App static assets to the .NET App’s /wwwroot where it can be previewed from https://localhost:5001.

Using Visual Studio

As your C# project grows you’ll want to consider running the back-end C# Solution with Visual Studio .NET with its much improved intelli-sense, navigation, tests runner & debug capabilities.

As we’ve never had a satisfactory experience trying develop npm SPA projects with VS.NET, we’d recommend only running the C# /api project in VS.NET and continuing to use VSCode for /ui project.

Deploying to Production

When you’re ready to deploy your App you can create a production build with:

$ npm run publish

Which will generate production builds of your C# projects and npm projects with its static generated UI assets written to /wwwroot to be deployed together with your complete .NET App.

Our recommendation for the best possible responsive UX is to deploy your App’s /wwwwroot static assets to a CDN in order for the initial load of your App to be downloaded from nearby CDN edge caches.

To do this configure the production url the UI should use for all its /api Ajax requests by modifying DEPLOY_API in your vite.config.ts:

const DEPLOY_API = 'https://vue-ssg-api.jamstacks.net'

This template also includes the necessary GitHub Actions to deploy this Apps production static assets to GitHub Pages CDN, for more info, checkout GitHub Actions Deployments.

Get Started

Driven by the static typing benefits of TypeScript, Vue 3 was itself written in TypeScript, a benefit that sees it extend to elevate TypeScript with first-class citizen support that development IDEs like Rider take full advantage of that’s used to power its type-safe & productive intelli-sense dev UX.
