+// This definition file follows a somewhat unusual format. ESTree allows
+// runtime type checks based on the `type` parameter. In order to explain this
+// to typescript we want to use discriminated union types:
+// https://github.com/Microsoft/TypeScript/pull/9163
+//
+// For ESTree this is a bit tricky because the high level interfaces like
+// Node or Function are pulling double duty. We want to pass common fields down
+// to the interfaces that extend them (like Identifier or
+// ArrowFunctionExpression), but you can't extend a type union or enforce
+// common fields on them. So we've split the high level interfaces into two
+// types, a base type which passes down inherited fields, and a type union of
+// all types which extend the base type. Only the type union is exported, and
+// the union is how other types refer to the collection of inheriting types.
+//
+// This makes the definitions file here somewhat more difficult to maintain,
+// but it has the notable advantage of making ESTree much easier to use as
+// an end user.

+
+## Asset URL handling
+
+When `@vitejs/plugin-vue` compiles the `<template>` blocks in SFCs, it also converts any encountered asset URLs into ESM imports.
+
+For example, the following template snippet:
+
+```vue
+<img src="../image.png" />
+```
+
+Is the same as:
+
+```vue
+<script setup>
+import _imports_0 from '../image.png'
+</script>
+
+<img :src="_imports_0" />
+```
+
+By default the following tag/attribute combinations are transformed, and can be configured using the `template.transformAssetUrls` option.
+
+```js
+{
+  video: ['src', 'poster'],
+  source: ['src'],
+  img: ['src'],
+  image: ['xlink:href', 'href'],
+  use: ['xlink:href', 'href']
+}
+```
+
+Note that only attribute values that are static strings are transformed. Otherwise, you'd need to import the asset manually, e.g. `import imgUrl from '../image.png'`.
+
+## Example for passing options to `vue/compiler-sfc`:
+
+```ts
+import vue from '@vitejs/plugin-vue'
+
+export default {
+  plugins: [
+    vue({
+      template: {
+        compilerOptions: {
+          // ...
+        },
+        transformAssetUrls: {
+          // ...
+        },
+      },
+    }),
+  ],
+}
+```
+
+## Example for transforming custom blocks
+
+```ts
+import vue from '@vitejs/plugin-vue'
+import yaml from 'js-yaml'
+
+const vueI18nPlugin = {
+  name: 'vue-i18n',
+  transform(code, id) {
+    // if .vue file don't have <i18n> block, just return
+    if (!/vue&type=i18n/.test(id)) {
+      return
+    }
+    // parse yaml
+    if (/\.ya?ml$/.test(id)) {
+      code = JSON.stringify(yaml.load(code.trim()))
+    }
+    // mount the value on the i18n property of the component instance
+    return `export default Comp => {
+      Comp.i18n = ${code}
+    }`
+  },
+}
+
+export default {
+  plugins: [vue(), vueI18nPlugin],
+}
+```
+
+Create a file named `Demo.vue`, add `lang="yaml"` to the `<i18n>` blocks, then you can use the syntax of `YAML`:
+
+```vue
+<template>Hello</template>
+
+<i18n lang="yaml">
+message: 'world'
+fullWord: 'hello world'
+</i18n>
+```
+
+`message` is mounted on the i18n property of the component instance, you can use like this:
+
+```vue
+<script setup lang="ts">
+import Demo from 'components/Demo.vue'
+</script>
+
+<template>
+  <Demo /> {{ Demo.i18n.message }}
+  <div>{{ Demo.i18n.fullWord }}</div>
+</template>
+```
+
+## Using Vue SFCs as Custom Elements
+
+> Requires `vue@^3.2.0` & `@vitejs/plugin-vue@^1.4.0`
+
+Vue 3.2 introduces the `defineCustomElement` method, which works with SFCs. By default, `<style>` tags inside SFCs are extracted and merged into CSS files during build. However when shipping a library of custom elements, it may be desirable to inline the styles as JavaScript strings and inject them into the custom elements' shadow root instead.
+
+Starting in 1.4.0, files ending with `*.ce.vue` will be compiled in "custom elements" mode: its `<style>` tags are compiled into inlined CSS strings and attached to the component as its `styles` property:
+
+```js
+import { defineCustomElement } from 'vue'
+import Example from './Example.ce.vue'
+
+console.log(Example.styles) // ['/* css content */']
+
+// register
+customElements.define('my-example', defineCustomElement(Example))
+```
+
+Note in custom elements mode there is no need to use `<style scoped>` since the CSS is already scoped inside the shadow DOM.
+
+The `customElement` plugin option can be used to configure the behavior:
+
+- `{ customElement: true }` will import all `*.vue` files in custom element mode.
+- Use a string or regex pattern to change how files should be loaded as Custom Elements (this check is applied after `include` and `exclude` matches).

+# @vue/compiler-sfc
+
+> Lower level utilities for compiling Vue Single File Components
+
+**Note: as of 3.2.13+, this package is included as a dependency of the main `vue` package and can be accessed as `vue/compiler-sfc`. This means you no longer need to explicitly install this package and ensure its version match that of `vue`'s. Just use the main `vue/compiler-sfc` deep import instead.**
+
+This package contains lower level utilities that you can use if you are writing a plugin / transform for a bundler or module system that compiles Vue Single File Components (SFCs) into JavaScript. It is used in [vue-loader](https://github.com/vuejs/vue-loader) and [@vitejs/plugin-vue](https://github.com/vitejs/vite-plugin-vue/tree/main/packages/plugin-vue).
+
+## API
+
+The API is intentionally low-level due to the various considerations when integrating Vue SFCs in a build system:
+
+- Separate hot-module replacement (HMR) for script, template and styles
+
+  - template updates should not reset component state
+  - style updates should be performed without component re-render
+
+- Leveraging the tool's plugin system for pre-processor handling. e.g. `<style lang="scss">` should be processed by the corresponding webpack loader.
+
+- In some cases, transformers of each block in an SFC do not share the same execution context. For example, when used with `thread-loader` or other parallelized configurations, the template sub-loader in `vue-loader` may not have access to the full SFC and its descriptor.
+
+The general idea is to generate a facade module that imports the individual blocks of the component. The trick is the module imports itself with different query strings so that the build system can handle each request as "virtual" modules:
+
+```
+                                  +--------------------+
+                                  |                    |
+                                  |  script transform  |
+                           +----->+                    |
+                           |      +--------------------+
+                           |
++--------------------+     |      +--------------------+
+|                    |     |      |                    |
+|  facade transform  +----------->+ template transform |
+|                    |     |      |                    |
++--------------------+     |      +--------------------+
+                           |
+                           |      +--------------------+
+                           +----->+                    |
+                                  |  style transform   |
+                                  |                    |
+                                  +--------------------+
+```
+
+Where the facade module looks like this:
+
+```js
+// main script
+import script from '/project/foo.vue?vue&type=script'
+// template compiled to render function
+import { render } from '/project/foo.vue?vue&type=template&id=xxxxxx'
+// css
+import '/project/foo.vue?vue&type=style&index=0&id=xxxxxx'
+
+// attach render function to script
+script.render = render
+
+// attach additional metadata
+// some of these should be dev only
+script.__file = 'example.vue'
+script.__scopeId = 'xxxxxx'
+
+// additional tooling-specific HMR handling code
+// using __VUE_HMR_API__ global
+
+export default script
+```
+
+### High Level Workflow
+
+1. In facade transform, parse the source into descriptor with the `parse` API and generate the above facade module code based on the descriptor;
+
+2. In script transform, use `compileScript` to process the script. This handles features like `<script setup>` and CSS variable injection. Alternatively, this can be done directly in the facade module (with the code inlined instead of imported), but it will require rewriting `export default` to a temp variable (a `rewriteDefault` convenience API is provided for this purpose) so additional options can be attached to the exported object.
+
+3. In template transform, use `compileTemplate` to compile the raw template into render function code.
+
+4. In style transform, use `compileStyle` to compile raw CSS to handle `<style scoped>`, `<style module>` and CSS variable injection.
+
+Options needed for these APIs can be passed via the query string.
+
+For detailed API references and options, check out the source type definitions. For actual usage of these APIs, check out [@vitejs/plugin-vue](https://github.com/vitejs/vite-plugin-vue/tree/main/packages/plugin-vue) or [vue-loader](https://github.com/vuejs/vue-loader/tree/next).

+
+## Usage Note
+
+This package is inlined into Global & Browser ESM builds of user-facing renderers (e.g. `@vue/runtime-dom`), but also published as a package that can be used standalone. The standalone build should not be used alongside a pre-bundled build of a user-facing renderer, as they will have different internal storage for reactivity connections. A user-facing renderer should re-export all APIs from this package.
+
+For full exposed APIs, see `src/index.ts`.
+
+## Credits
+
+The implementation of this module is inspired by the following prior art in the JavaScript ecosystem:
+
+- [Meteor Tracker](https://docs.meteor.com/api/tracker.html)
+- [nx-js/observer-util](https://github.com/nx-js/observer-util)
+- [salesforce/observable-membrane](https://github.com/salesforce/observable-membrane)
+
+## Caveats
+
+- Built-in objects are not observed except for `Array`, `Map`, `WeakMap`, `Set` and `WeakSet`.

+# @vue/server-renderer
+
+**Note: as of 3.2.13+, this package is included as a dependency of the main `vue` package and can be accessed as `vue/server-renderer`. This means you no longer need to explicitly install this package and ensure its version match that of `vue`'s. Just use the `vue/server-renderer` deep import instead.**
+
+## Basic API
+
+### `renderToString`
+
+**Signature**
+
+```ts
+function renderToString(
+  input: App | VNode,
+  context?: SSRContext,
+): Promise<string>
+```
+
+**Usage**
+
+```js
+const { createSSRApp } = require('vue')
+const { renderToString } = require('@vue/server-renderer')
+
+const app = createSSRApp({
+  data: () => ({ msg: 'hello' }),
+  template: `<div>{{ msg }}</div>`,
+})
+
+;(async () => {
+  const html = await renderToString(app)
+  console.log(html)
+})()
+```
+
+### Handling Teleports
+
+If the rendered app contains teleports, the teleported content will not be part of the rendered string. Instead, they are exposed under the `teleports` property of the ssr context object:
+
+```js
+const ctx = {}
+const html = await renderToString(app, ctx)
+
+console.log(ctx.teleports) // { '#teleported': 'teleported content' }
+```
+
+## Streaming API
+
+### `renderToNodeStream`
+
+Renders input as a [Node.js Readable stream](https://nodejs.org/api/stream.html#stream_class_stream_readable).
+
+**Signature**
+
+```ts
+function renderToNodeStream(input: App | VNode, context?: SSRContext): Readable
+```
+
+**Usage**
+
+```js
+// inside a Node.js http handler
+renderToNodeStream(app).pipe(res)
+```
+
+**Note:** This method is not supported in the ESM build of `@vue/server-renderer`, which is decoupled from Node.js environments. Use `pipeToNodeWritable` instead.
+
+### `pipeToNodeWritable`
+
+Render and pipe to an existing [Node.js Writable stream](https://nodejs.org/api/stream.html#stream_writable_streams) instance.
+
+**Signature**
+
+```ts
+function pipeToNodeWritable(
+  input: App | VNode,
+  context: SSRContext = {},
+  writable: Writable,
+): void
+```
+
+**Usage**
+
+```js
+// inside a Node.js http handler
+pipeToNodeWritable(app, {}, res)
+```
+
+### `renderToWebStream`
+
+Renders input as a [Web ReadableStream](https://developer.mozilla.org/en-US/docs/Web/API/Streams_API).
+
+**Signature**
+
+```ts
+function renderToWebStream(
+  input: App | VNode,
+  context?: SSRContext,
+): ReadableStream
+```
+
+**Usage**
+
+```js
+// inside an environment with ReadableStream support
+return new Response(renderToWebStream(app))
+```
+
+**Note:** in environments that do not expose `ReadableStream` constructor in the global scope, `pipeToWebWritable` should be used instead.
+
+### `pipeToWebWritable`
+
+Render and pipe to an existing [Web WritableStream](https://developer.mozilla.org/en-US/docs/Web/API/WritableStream) instance.
+
+**Signature**
+
+```ts
+function pipeToWebWritable(
+  input: App | VNode,
+  context: SSRContext = {},
+  writable: WritableStream,
+): void
+```
+
+**Usage**
+
+This is typically used in combination with [`TransformStream`](https://developer.mozilla.org/en-US/docs/Web/API/TransformStream):
+
+```js
+// TransformStream is available in environments such as CloudFlare workers.
+// in Node.js, TransformStream needs to be explicitly imported from 'stream/web'
+const { readable, writable } = new TransformStream()
+pipeToWebWritable(app, {}, writable)
+
+return new Response(readable)
+```
+
+### `renderToSimpleStream`
+
+Renders input in streaming mode using a simple readable interface.
+
+**Signature**
+
+```ts
+function renderToSimpleStream(
+  input: App | VNode,
+  context: SSRContext,
+  options: SimpleReadable,
+): SimpleReadable
+
+interface SimpleReadable {
+  push(content: string | null): void
+  destroy(err: any): void
+}
+```
+
+**Usage**
+
+```js
+let res = ''
+
+renderToSimpleStream(
+  app,
+  {},
+  {
+    push(chunk) {
+      if (chunk === null) {
+        // done
+        console(`render complete: ${res}`)
+      } else {
+        res += chunk
+      }
+    },
+    destroy(err) {
+      // error encountered
+    },
+  },
+)
+```
