@json-render/image

Image renderer that converts JSON specs into SVG and PNG images using Satori.

Quick Start

import { renderToPng } from "@json-render/image/render";
import type { Spec } from "@json-render/core";

const spec: Spec = {
  root: "frame",
  elements: {
    frame: {
      type: "Frame",
      props: { width: 1200, height: 630, backgroundColor: "#1a1a2e" },
      children: ["heading"],
    },
    heading: {
      type: "Heading",
      props: { text: "Hello World", level: "h1", color: "#ffffff" },
      children: [],
    },
  },
};

const png = await renderToPng(spec, {
  fonts: [{ name: "Inter", data: fontData, weight: 400, style: "normal" }],
});

Using Standard Components

import { defineCatalog } from "@json-render/core";
import { schema, standardComponentDefinitions } from "@json-render/image";

export const imageCatalog = defineCatalog(schema, {
  components: standardComponentDefinitions,
});

Adding Custom Components

import { z } from "zod";

const catalog = defineCatalog(schema, {
  components: {
    ...standardComponentDefinitions,
    Badge: {
      props: z.object({ label: z.string(), color: z.string().nullable() }),
      slots: [],
      description: "A colored badge label",
    },
  },
});
