- `customElement: boolean | RegExp`: enable custom elements mode.
- `customElement: boolean | RegExp`: enable custom elements mode. An SFC loaded in custom elements mode inlines its `<style>` tags as strings under the component's `styles` option. When used with `defineCustomElement` from Vue core, the styles will be injected into the custom element's shadow root.
- Default is `/\.ce\.vue$/`
- Setting to `true` will load all `.vue` files as native Custom Elements.

2. We want the content in `script` block to be treated like `.js` files (and if it's `<script lang="ts">`, we want to to be treated like `.ts` files). Same for other language blocks. So we want webpack to apply any configured module rules that matches `.js` also to requests that look like `source.vue?vue&type=script`. This is what `VueLoaderPlugin` (`src/plugins.ts`) does: for each module rule in the webpack config, it creates a modified clone that targets corresponding Vue language block requests.
Suppose we have configured `babel-loader` for all `*.js` files. That rule will be cloned and applied to Vue SFC `<script>` blocks as well. Internally to webpack, a request like

This time though, the loader notices that the request has queries and is targeting a specific block only. So it selects (`src/select.ts`) the inner content of the target block and passes it on to the loaders matched after it.

- We need to compile the template using the Vue template compiler;
- We need to post-process the CSS in `<style scoped>` blocks, **after** `css-loader` but **before** `style-loader`.

Technically, these are additional loaders (`src/templateLoader.ts` and `src/stylePostLoader.ts`) that need to be injected into the expanded loader chain. It would be very complicated if the end users have to configure this themselves, so `VueLoaderPlugin` also injects a global [Pitching Loader](https://webpack.js.org/api/loaders/#pitching-loader) (`src/pitcher.ts`) that intercepts Vue `<template>` and `<style>` requests and injects the necessary loaders.
