Applies the typescript compiler during vite transform build phase.
npm install --save-dev vite-plugin-typescript-transformSee the Options interface.
As of now, vite uses esbuild to transpile typescript, which doesn't yet support the new ECMAScript decorators.
But typescript added support for them in v5.
This example transpiles the new ECMAScript decorators into code that is usable in runtimes that do not yet support it.
import { vitePluginTypescriptTransform } from 'vite-plugin-typescript-transform';
import { defineConfig } from 'vitest/config';
export default defineConfig({
