Serialisasi dasar

import { hastToHtml } from "@unifast/core";
import type { HastRoot } from "@unifast/core";

const hast: HastRoot = {
  type: "root",
  children: [
    {
      type: "element",
      tagName: "p",
      properties: {},
      children: [
        { type: "text", value: "This is " },

const hast: HastRoot = {
  type: "root",
  children: [
    {
      type: "element",
      tagName: "img",
      properties: { src: "photo.jpg", alt: "A photo" },
      children: [],
    },
  ],
};

console.log(hastToHtml(hast));
// <img alt="A photo" src="photo.jpg" />

Dengan output compile()

import { compile } from "@unifast/node";
import { hastToHtml } from "@unifast/core";
import type { HastRoot } from "@unifast/core";

const result = compile("**bold text**", { outputKind: "hast" });
const hast: HastRoot = JSON.parse(result.output as string);

console.log(hastToHtml(hast));
// <p><strong>bold text</strong></p>

import { hastToHtml } from "@unifast/core";
import type { HastRoot } from "@unifast/core";

  type: "root",
  children: [
    { type: "raw", value: "<div class=\"custom\">Raw HTML</div>" },
  ],
};

console.log(hastToHtml(hast));
// <div class="custom">Raw HTML</div>
