A TypeScript implementation of JSON-DOC, a standardized format for storing structured content in JSON files, inspired by Notion's data model.

• Programmatically Generated Types: All TypeScript interfaces are automatically generated from JSON schemas
• React Renderer: Complete React component library for rendering JSON-DOC content
• Rich Content Support: Supports all major block types including paragraphs, headings, lists, tables, images, and more
• Recursive Rendering: Handles nested blocks at arbitrary depth
• Notion-like Styling: CSS styling inspired by Notion's visual design

npm install @textcortex/jsondoc

import React from "react";
import { JsonDocRenderer } from "@textcortex/jsondoc";
import * as fs from "fs";
import * as JSON5 from "json5";

// Load JSON-DOC data (with comment support)
const pageData = JSON5.parse(fs.readFileSync("document.json", "utf-8"));

// Render the document
function App() {
  return (
    <div>
      <JsonDocRenderer page={pageData} />
    </div>
  );
}

import React from "react";
import { BlockRenderer } from "@textcortex/jsondoc";

function MyComponent({ block }) {
  return (
    <div>
      <BlockRenderer block={block} depth={0} />
    </div>
  );
}

View any JSON-DOC file directly in your browser with a single command:

# View a JSON-DOC file
npm run view path/to/your/document.json

# Example: View the test document
npm run view ../schema/page/ex1_success.json

This will:

1. Start a local server at http://localhost:3000
2. Automatically open your browser
3. Render the JSON-DOC file with full styling
4. Support all block types including nested structures

The viewer includes:

• Live rendering of all supported block types
• Notion-like styling with responsive design
• Automatic browser opening for convenience
• File information in the header (filename, block count)
• Comment support using JSON5 parsing

The renderer supports all major JSON-DOC block types:

• Text Blocks: paragraph, heading_1, heading_2, heading_3
• List Blocks: bulleted_list_item, numbered_list_item
• Rich Content: code, quote, equation
• Media: image (both external URLs and file references)
• Layout: table, table_row, column_list, column
• Interactive: to_do, toggle
• Utility: divider

Rich text content supports:

• Formatting: Bold, italic, strikethrough, underline, code
• Colors: All Notion color options
• Links: External links with proper target="_blank"
• Equations: Inline mathematical expressions

# Install dependencies
npm install

# Generate TypeScript types from JSON schemas
npm run generate-types

# Build the project
npm run build

# Run tests
npm test

# View example JSON-DOC file in browser
npm run view ../schema/page/ex1_success.json

The test suite includes:

# Run all tests
npm test

# Tests cover:
# - JSON utility functions (loadJson, deepClone)
# - Example file loading with comment support
# - Block type detection and validation

The tests verify:

• ✅ JSON loading and parsing functionality
• ✅ Deep cloning of complex objects
• ✅ Loading of the comprehensive example file (47 blocks, 16 types)
• ✅ Block type enumeration and structure validation

• src/models/: TypeScript type definitions (generated from schemas)
• src/renderer/: React components for rendering JSON-DOC
• src/utils/: Helper functions
• tests/: Test suite

JSON-DOC uses a hierarchical structure similar to Notion:

{
  "object": "page",
  "id": "page-id",
  "properties": {
    "title": {
      "title": [
        {
          "type": "text",
          "text": { "content": "Document Title" }
        }
      ]
    }
  },
  "children": [
    {
      "object": "block",
      "type": "paragraph",
      "id": "block-id",
      "paragraph": {
        "rich_text": [
          {
            "type": "text",
            "text": { "content": "Hello, world!" },
            "annotations": {
              "bold": true,
              "color": "blue"
            }
          }
        ]
      },
      "children": []
    }
  ]
}

1. Recursive Rendering: All block renderers support children blocks with proper nesting
2. Type Safety: Full TypeScript support with generated types
3. Accessibility: Proper ARIA attributes and semantic HTML
4. Responsive Design: Mobile-friendly layout with responsive columns
5. Interactive Elements: Toggle blocks can be expanded/collapsed, to-do items show state

The renderer uses Notion-inspired CSS classes for styling:

• .json-doc-renderer - Main container
• .notion-selectable - Individual blocks
• .notion-text-block, .notion-header-block - Block types
• .notion-list-item-box-left - List item bullets/numbers
• .notion-table-content - Table containers
• .notion-inline-code - Inline code formatting

We use bumpp to automatically bump package.json and lock files, create git tags and commits

1. Run:

 npx bumpp

2. You should see:

4 Commits since the last version:

5217cd1   : update readme
7a3c03d   : Expose page delimiter
e2791a4   : Merge branch 'main' of github.com:textcortex/JSON-DOC
b7b30c1   : Make more typesafe

✔ Current version 0.2.0-alpha.3 ›          next 0.2.0-alpha.4

   files package-lock.json
         package.json
  commit chore: release v0.2.0-alpha.4
     tag typescript-v0.2.0-alpha.4

    from 0.2.0-alpha.3
      to 0.2.0-alpha.4

You can choose a different version from the list or create new one. But bumpp is smart enough to use appropriate next version.

3. Verify and confirm
4. Push commit and tag

git push --follow-tags

5. The new tag will trigger a release on github actions.
6. Go to github and create release using the new tag. Make sure you set the correct previous tag prefixed with typescript-v

• setup eslint

      "**/generated/**",
      "src/serialization/**",
  

• add counter for numbered lists

• setup up bumpp: https://www.npmjs.com/package/bumpp

• migrate test runner to vitest

• move vite app to typescript root examples dir

• setup monorepo tooling

• fix model generation for Image and RichText, then type renderers

• use katex or similar package for equations

• add error boundry

• add page title highlighting

• validate page prop somehow. not clear how to do yet. we can't use the /schema because it's HUGE and also because it's outside of /typescript. Will need to think about this.

maybe do something like this?

import type { Page } from "../models/generated/page/page";
import { isPage } from "../models/generated/essential-types";

export function validatePage(obj: unknown): obj is Page {
  console.log("isPage(obj) ", isPage(obj));
  return (
    isPage(obj) &&
    typeof (obj as any).id === "string" &&
    Array.isArray((obj as any).children)
  );
}

export function validatePageWithError(obj: unknown): {
  valid: boolean;
  error?: string;
} {
  if (!isPage(obj)) {
    return { valid: false, error: "Not a valid page object" };
  }

  if (typeof (obj as any).id !== "string") {
    return { valid: false, error: "Page id must be a string" };
  }

  if (!Array.isArray((obj as any).children)) {
    return { valid: false, error: "Page children must be an array" };
  }

  return { valid: true };
}

will require us to write a validator and we won't benefit from the defined schema jsons.
