Is it possible to set up Vite/Rollup to exclusively execute vue-tsc on entrypoints' included dependencies?

Yes, it is possible to set up Vite/Rollup to exclusively execute vue-tsc on entrypoints' included dependencies. This can be done by configuring the rollup-plugin-typescript2 plugin to use vue-tsc as the TypeScript compiler.

Here's an example Vite configuration:

// vite.config.js
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import { createVuePlugin } from 'vite-plugin-vue2'
import typescript from 'rollup-plugin-typescript2'

export default defineConfig({
  plugins: [
    vue(),
    createVuePlugin(),
    typescript({
      typescript: require('vue-tsc'),
      useTsconfigDeclarationDir: true,
      tsconfigOverride: {
        compilerOptions: {
          declaration: true,
          declarationDir: './dist/types',
        },
        include: ['path/to/entrypoints/**/*'], // Change this to match your entrypoints
        exclude: ['node_modules'],
      }
    })
  ]
})

Note the typescript options:

• typescript: require('vue-tsc'): This sets the TypeScript compiler to vue-tsc.
• useTsconfigDeclarationDir: true: This tells the TypeScript plugin to use the declarationDir specified in the tsconfigOverride.
• tsconfigOverride: This sets options specific to the TypeScript configuration. In this case, we're setting the declaration option to true to generate TypeScript declaration files, and the declarationDir option to ./dist/types to output them into this directory. We're also setting the include option to only process files in path/to/entrypoints, and excluding node_modules.

With this configuration, Vite/Rollup will only execute vue-tsc on the included dependencies of the specified entrypoints.
