Hello world

\n```\n\n## 示例\n\n### 基础序列化\n\n```ts\nimport { hastToHtml } from \"@unifast/core\";\nimport type { HastRoot } from \"@unifast/core\";\n\nconst hast: HastRoot = {\n type: \"root\",\n children: [\n {\n type: \"element\",\n tagName: \"p\",\n properties: {},\n children: [\n { type: \"text\", value: \"This is \" },\n {\n type: \"element\",\n tagName: \"strong\",\n properties: {},\n children: [{ type: \"text\", value: \"bold\" }],\n },\n { type: \"text\", value: \" text.\" },\n ],\n },\n ],\n};\n\nconsole.log(hastToHtml(hast));\n//

This is bold text.

\n```\n\n### 空元素\n\n空元素（`
`、``、`
` 等）会自动以自闭合形式输出：\n\n```ts\nimport { hastToHtml } from \"@unifast/core\";\nimport type { HastRoot } from \"@unifast/core\";\n\nconst hast: HastRoot = {\n type: \"root\",\n children: [\n {\n type: \"element\",\n tagName: \"img\",\n properties: { src: \"photo.jpg\", alt: \"A photo\" },\n children: [],\n },\n ],\n};\n\nconsole.log(hastToHtml(hast));\n// \"A\n```\n\n### 配合 compile() 输出使用\n\n```ts\nimport { compile } from \"@unifast/node\";\nimport { hastToHtml } from \"@unifast/core\";\nimport type { HastRoot } from \"@unifast/core\";\n\nconst result = compile(\"**bold text**\", { outputKind: \"hast\" });\nconst hast: HastRoot = JSON.parse(result.output as string);\n\nconsole.log(hastToHtml(hast));\n//

bold text

\n```\n\n### 原始 HTML 透传\n\n```ts\nimport { hastToHtml } from \"@unifast/core\";\nimport type { HastRoot } from \"@unifast/core\";\n\nconst hast: HastRoot = {\n type: \"root\",\n children: [\n { type: \"raw\", value: \"

\" },\n ],\n};\n\nconsole.log(hastToHtml(hast));\n//
Raw HTML
