@json-render/solid

@json-render/solid renders json-render specs into Solid component trees with fine-grained reactivity.

Quick Start

import { Renderer, JSONUIProvider } from "@json-render/solid";
import type { Spec } from "@json-render/solid";
import { registry } from "./registry";

export function App(props: { spec: Spec | null }) {
  return (
    <JSONUIProvider registry={registry} initialState={{}}>
      <Renderer spec={props.spec} registry={registry} />
    </JSONUIProvider>
  );
}

Create a Catalog

import { defineCatalog } from "@json-render/core";
import { schema } from "@json-render/solid/schema";
import { z } from "zod";

export const catalog = defineCatalog(schema, {
  components: {
    Button: {
      props: z.object({
        label: z.string(),
        variant: z.enum(["primary", "secondary"]).nullable(),
      }),
      description: "Clickable button",
    },
    Card: {
      props: z.object({ title: z.string() }),
      description: "Card container",
    },
  },
  actions: {
    submit: { description: "Submit data" },
  },
});

Define Components

Components receive ComponentRenderProps from the renderer:

interface ComponentRenderProps<P = Record<string, unknown>> {
  element: UIElement<string, P>;
  children?: JSX.Element;
  emit: (event: string) => void;
  on: (event: string) => EventHandle;
  bindings?: Record<string, string>;
  loading?: boolean;
}

Example:

import type { BaseComponentProps } from "@json-render/solid";

export function Button(props: BaseComponentProps<{ label: string }>) {
  return (
    <button onClick={() => props.emit("press")}>{props.props.label}</button>
  );
}

Create a Registry

import { defineRegistry } from "@json-render/solid";
import { catalog } from "./catalog";
import { Card } from "./Card";
import { Button } from "./Button";

const { registry, handlers, executeAction } = defineRegistry(catalog, {
  components: {
    Card,
    Button,
  },
  actions: {
    submit: async (params, setState, state) => {
      // custom action logic
    },
  },
});
