A high level overview of tools used:
- [TypeScript](https://www.typescriptlang.org/) as the development language
-- [Vite](https://vitejs.dev/) and [ESBuild](https://esbuild.github.io/) for development bundling
+- [Vite](https://vite.dev/) and [ESBuild](https://esbuild.github.io/) for development bundling
- [Rollup](https://rollupjs.org) for production bundling
- [Vitest](https://vitest.dev/) for unit testing
- [Prettier](https://prettier.io/) for code formatting
- Internet Explorer 11 support: [Vue 3 has officially dropped the plan for IE11 support](https://github.com/vuejs/rfcs/blob/master/active-rfcs/0038-vue3-ie11-support.md). If you still need to support IE11 or below, you will have to stay on Vue 2.
-- Server-side rendering: the migration build can be used for SSR, but migrating a custom SSR setup is much more involved. The general idea is replacing `vue-server-renderer` with [`@vue/server-renderer`](https://github.com/vuejs/core/tree/main/packages/server-renderer). Vue 3 no longer provides a bundle renderer and it is recommended to use Vue 3 SSR with [Vite](https://vitejs.dev/guide/ssr.html). If you are using [Nuxt.js](https://nuxtjs.org/), it is probably better to wait for Nuxt 3.

### Expectations
1. Upgrade tooling if applicable.
- If using custom webpack setup: Upgrade `vue-loader` to `^16.0.0`.
- If using `vue-cli`: upgrade to the latest `@vue/cli-service` with `vue upgrade`
- - (Alternative) migrate to [Vite](https://vitejs.dev/) + [vite-plugin-vue2](https://github.com/underfin/vite-plugin-vue2). [[Example commit](https://github.com/vuejs/vue-hackernews-2.0/commit/565b948919eb58f22a32afca7e321b490cb3b074)]

2. In `package.json`, update `vue` to 3.1, install `@vue/compat` of the same version, and replace `vue-template-compiler` (if present) with `@vue/compiler-sfc`:
