Hello world

\n```\n\n## Ejemplos\n\n### Serialización básica\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### Elementos vacíos (void)\n\nLos elementos vacíos (`
`, ``, `
`, etc.) se autocierran automáticamente:\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### Con la salida de compile()\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### Paso de HTML crudo\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: \"
Raw HTML
\" },\n ],\n};\n\nconsole.log(hastToHtml(hast));\n//
Raw HTML
\n```\n\n## Comportamiento\n\n- **Escape HTML:** el contenido de texto se escapa (`&`, `<`, `>`, `\"`)\n- **Elementos void:** `area`, `base`, `br`, `col`, `embed`, `hr`, `img`, `input`, `link`, `meta`, `param`, `source`, `track`, `wbr` se autocierran\n- **Atributos:** ordenados alfabéticamente; los arrays `className` se unen con espacios y se renderizan como `class`; el booleano `true` se renderiza como un atributo sin valor; `false`/`null`/`undefined` se omiten\n- **Comentarios:** se renderizan como ``\n- **Doctype:** se renderiza como ``\n- **Nodos raw:** se emiten tal cual, sin escape", "alternates": [ { "locale": "en", "url": "https://unifast.dev/docs/packages/core/hast-to-html/", "api": "https://unifast.dev//api/docs/packages/core/hast-to-html.json" }, { "locale": "ja", "url": "https://unifast.dev/ja/docs/packages/core/hast-to-html/", "api": "https://unifast.dev//api/ja/docs/packages/core/hast-to-html.json" }, { "locale": "zh-CN", "url": "https://unifast.dev/zh-CN/docs/packages/core/hast-to-html/", "api": "https://unifast.dev//api/zh-CN/docs/packages/core/hast-to-html.json" }, { "locale": "zh-TW", "url": "https://unifast.dev/zh-TW/docs/packages/core/hast-to-html/", "api": "https://unifast.dev//api/zh-TW/docs/packages/core/hast-to-html.json" }, { "locale": "ko", "url": "https://unifast.dev/ko/docs/packages/core/hast-to-html/", "api": "https://unifast.dev//api/ko/docs/packages/core/hast-to-html.json" }, { "locale": "fr", "url": "https://unifast.dev/fr/docs/packages/core/hast-to-html/", "api": "https://unifast.dev//api/fr/docs/packages/core/hast-to-html.json" }, { "locale": "it", "url": "https://unifast.dev/it/docs/packages/core/hast-to-html/", "api": "https://unifast.dev//api/it/docs/packages/core/hast-to-html.json" }, { "locale": "es", "url": "https://unifast.dev/es/docs/packages/core/hast-to-html/", "api": "https://unifast.dev//api/es/docs/packages/core/hast-to-html.json" }, { "locale": "pt-BR", "url": "https://unifast.dev/pt-BR/docs/packages/core/hast-to-html/", "api": "https://unifast.dev//api/pt-BR/docs/packages/core/hast-to-html.json" }, { "locale": "de", "url": "https://unifast.dev/de/docs/packages/core/hast-to-html/", "api": "https://unifast.dev//api/de/docs/packages/core/hast-to-html.json" }, { "locale": "ru", "url": "https://unifast.dev/ru/docs/packages/core/hast-to-html/", "api": "https://unifast.dev//api/ru/docs/packages/core/hast-to-html.json" }, { "locale": "hi", "url": "https://unifast.dev/hi/docs/packages/core/hast-to-html/", "api": "https://unifast.dev//api/hi/docs/packages/core/hast-to-html.json" }, { "locale": "id", "url": "https://unifast.dev/id/docs/packages/core/hast-to-html/", "api": "https://unifast.dev//api/id/docs/packages/core/hast-to-html.json" }, { "locale": "tr", "url": "https://unifast.dev/tr/docs/packages/core/hast-to-html/", "api": "https://unifast.dev//api/tr/docs/packages/core/hast-to-html.json" }, { "locale": "vi", "url": "https://unifast.dev/vi/docs/packages/core/hast-to-html/", "api": "https://unifast.dev//api/vi/docs/packages/core/hast-to-html.json" } ] }
