Shiny + Golem + Vue 3 + Vite

This repo contains an example for using Vue 3 + Vite with a {golem} shiny app.

yarn create vite vite-demo --template vue
cd vite-demo
R -e "golem::create_golem('vite.demo')"
mv vite.demo/* .
rm -r vite.demo /

Edit the vite.config.js file to look like this to make sure the built files are in the right location for shiny.

import { defineConfig } from "vite";
import vue from "@vitejs/plugin-vue";

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [vue()],
  build: {
    outDir: "./inst/app/",
    assetsDir: "www",
  },
});

R/app_ui should have

app_ui <- function(request) {
    tagList(
        # Leave this function for adding external resources
        golem_add_external_resources(),
        # Your application UI logic
        shiny::htmlTemplate(
            system.file("app/index.html", package = "vite.demo")
        )
    )
}

replace vite.demo with the name of the golem package.

Use yarn build to populate the www/ folder with the built Vue scripts, then use golem::run_dev() to start the shiny app.

You could add an additional line to dev/run_dev.R like
