+
+## What is this?
+
+This package contains two extensions that add support for MDX ESM syntax in
+markdown to [mdast][].
+These extensions plug into
+[`mdast-util-from-markdown`][mdast-util-from-markdown] (to support parsing
+ESM in markdown into a syntax tree) and
+[`mdast-util-to-markdown`][mdast-util-to-markdown] (to support serializing
+ESM in syntax trees to markdown).
+
+## When to use this
+
+You can use these extensions when you are working with
+`mdast-util-from-markdown` and `mdast-util-to-markdown` already.
+
+When working with `mdast-util-from-markdown`, you must combine this package
+with [`micromark-extension-mdxjs-esm`][extension].
+
+When you are working with syntax trees and want all of MDX, use
+[`mdast-util-mdx`][mdast-util-mdx] instead.
+
+All these packages are used in [`remark-mdx`][remark-mdx], which
+focusses on making it easier to transform content by abstracting these
+internals away.
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 16+), install with [npm][]:
+
+```sh
+npm install mdast-util-mdxjs-esm
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {mdxjsEsmFromMarkdown, mdxjsEsmToMarkdown} from 'https://esm.sh/mdast-util-mdxjs-esm@2'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+<script type="module">
+  import {mdxjsEsmFromMarkdown, mdxjsEsmToMarkdown} from 'https://esm.sh/mdast-util-mdxjs-esm@2?bundle'
+</script>
+```
+
+## Use
+
+Say our document `example.mdx` contains:
+
+```mdx
+import a from 'b'
+export const c = ''
+
+d
+```
+
+…and our module `example.js` looks as follows:
+
+```js
+import fs from 'node:fs/promises'
+import * as acorn from 'acorn'
+import {fromMarkdown} from 'mdast-util-from-markdown'
+import {toMarkdown} from 'mdast-util-to-markdown'
+import {mdxjsEsm} from 'micromark-extension-mdxjs-esm'
+import {mdxjsEsmFromMarkdown, mdxjsEsmToMarkdown} from 'mdast-util-mdxjs-esm'
+
+const doc = await fs.readFile('example.mdx')
+
+const tree = fromMarkdown(doc, {
+  extensions: [mdxjsEsm({acorn, addResult: true})],
+  mdastExtensions: [mdxjsEsmFromMarkdown()]
+})
+
+console.log(tree)
+
+const out = toMarkdown(tree, {extensions: [mdxjsEsmToMarkdown()]})
+
+console.log(out)
+```
+
+…now running `node example.js` yields (positional info removed for brevity):
+
+```js
+{
+  type: 'root',
+  children: [
+    {
+      type: 'mdxjsEsm',
+      value: "import a from 'b'\nexport const c = ''",
+      data: {
+        estree: {

+                {
+                  type: 'ImportDefaultSpecifier',
+                  local: {type: 'Identifier', name: 'a'}
+                }
+              ],
+              source: {type: 'Literal', value: 'b', raw: "'b'"}
+            },

+                    type: 'VariableDeclarator',
+                    id: {type: 'Identifier', name: 'c'},
+                    init: {type: 'Literal', value: '', raw: "''"}
+                  }
+                ],
+                kind: 'const'
+              },
+              specifiers: [],

+            }
+          ],

+      }
+    },
+    {type: 'paragraph', children: [{type: 'text', value: 'd'}]}

+
+```markdown

+
+## API
+
+This package exports the identifiers
+[`mdxjsEsmFromMarkdown`][api-mdxjs-esm-from-markdown] and
+[`mdxjsEsmToMarkdown`][api-mdxjs-esm-to-markdown].
+There is no default export.
+
+### `mdxjsEsmFromMarkdown()`
+
+Create an extension for [`mdast-util-from-markdown`][mdast-util-from-markdown]
+to enable MDX.js ESM in markdown.
+
+When using the [micromark syntax extension][extension] with `addResult`, nodes
+will have a `data.estree` field set to an ESTree [`Program`][program] node.
+
+###### Returns
+
+Extension for `mdast-util-from-markdown` to enable MDX.js ESM
+([`FromMarkdownExtension`][from-markdown-extension]).
+
+### `mdxjsEsmToMarkdown()`
+
+Create an extension for [`mdast-util-to-markdown`][mdast-util-to-markdown]
+to enable MDX.js ESM in markdown.
+
+###### Returns
+
+Extension for `mdast-util-to-markdown` to enable MDX.js ESM
+([`ToMarkdownExtension`][to-markdown-extension]).
+
+### `MdxjsEsm`
+
+MDX ESM (import/export) node (TypeScript type).
+
+###### Type
+
+```ts
+import type {Program} from 'estree-jsx'
+import type {Data, Literal} from 'mdast'
+
+interface MdxjsEsm extends Literal {
+  type: 'mdxjsEsm'
+  data?: MdxjsEsmData | undefined
+}
+
+export interface MdxjsEsmData extends Data {
+  estree?: Program | null | undefined
+}
+```
+
+### `MdxjsEsmHast`
+
+Same as [`MdxjsEsm`][api-mdxjs-esm], but registered with `@types/hast`
+(TypeScript type).
+
+###### Type
+
+```ts
+import type {Program} from 'estree-jsx'
+import type {Data, Literal} from 'hast'
+
+interface MdxjsEsmHast extends Literal {
+  type: 'mdxjsEsm'
+  data?: MdxjsEsmHastData | undefined
+}
+
+export interface MdxjsEsmHastData extends Data {
+  estree?: Program | null | undefined
+}
+```
+
+## HTML
+
+MDX ESM has no representation in HTML.
+Though, when you are dealing with MDX, you will likely go *through* hast.
+You can enable passing MDX ESM through to hast by configuring
+[`mdast-util-to-hast`][mdast-util-to-hast] with `passThrough: ['mdxjsEsm']`.
+
+## Syntax
+
+See [Syntax in `micromark-extension-mdxjs-esm`][syntax].
+
+## Syntax tree
+
+The following interfaces are added to **[mdast][]** by this utility.
+
+### Nodes
+
+#### `MdxjsEsm`
+
+```idl
+interface MdxjsEsm <: Literal {
+  type: 'mdxjsEsm'
+}
+```
+
+**MdxjsEsm** (**[Literal][dfn-literal]**) represents ESM import/exports
+embedded in MDX.
+It can be used where **[flow][dfn-flow-content]** content is expected.
+Its content is represented by its `value` field.
+
+For example, the following Markdown:
+
+```markdown
+import a from 'b'
+```
+
+Yields:
+
+```js
+{
+  type: 'mdxjsEsm',
+  value: 'import a from \'b\''
+}
+```
+
+### Content model
+
+#### `FlowContent` (MDX.js ESM)
+
+```idl
+type FlowContentMdxjsEsm = MdxjsEsm | FlowContent
+```
+
+Note that when ESM is present, it can only exist as top-level content: if it has
+a *[parent][dfn-parent]*, that parent must be **[Root][dfn-root]**.
+
+## Types
+
+This package is fully typed with [TypeScript][].
+It exports the additional types [`MdxjsEsm`][api-mdxjs-esm] and
+[`MdxjsEsmHast`][api-mdxjs-esm-hast].
+
+It also registers the node type with `@types/mdast` and `@types/hast`.
+If you’re working with the syntax tree, make sure to import this utility
+somewhere in your types, as that registers the new node types in the tree.
+
+```js
+/**
+ * @typedef {import('mdast-util-mdxjs-esm')}
+ */
+
+import {visit} from 'unist-util-visit'
+
+/** @type {import('mdast').Root} */
+const tree = getMdastNodeSomeHow()
+
+visit(tree, function (node) {
+  // `node` can now be an ESM node.
+})
+```
+
+## Compatibility
+
+Projects maintained by the unified collective are compatible with maintained
+versions of Node.js.
+
+When we cut a new major release, we drop support for unmaintained versions of
+Node.
+This means we try to keep the current release line, `mdast-util-mdxjs-esm@^2`,
+compatible with Node.js 16.
+
+This utility works with `mdast-util-from-markdown` version 2+ and
+`mdast-util-to-markdown` version 2+.
