📦 Installation

Basic Installation (without Chart support)

npm install @pubwave/editor
# or
yarn add @pubwave/editor
# or
pnpm add @pubwave/editor

With Chart Support

If you want to use Chart blocks, also install Chart.js:

npm install @pubwave/editor chart.js
# or
yarn add @pubwave/editor chart.js
# or
pnpm add @pubwave/editor chart.js

Note: chart.js is an optional peer dependency. Only install it if you plan to use Chart block functionality.

🚀 Quick Start

import { PubwaveEditor } from '@pubwave/editor';
import '@pubwave/editor/style.css';

function MyEditor() {
  const [content, setContent] = useState({
    type: 'doc',

EditorAPI Methods

The editor exposes a public API through the ref prop or onReady callback:

import { useRef } from 'react';
import type { EditorAPI } from '@pubwave/editor';

const editorRef = useRef<EditorAPI | null>(null);

<PubwaveEditor
  ref={editorRef}
  onReady={(api) => {
    editorRef.current = api;
  }}
/>;

// Later, use the API
editorRef.current?.setContent(newContent);
editorRef.current?.getJSON();
editorRef.current?.toggleBold();

🖼️ Image Upload

The editor supports two image upload modes:

1. Base64 (Default) - Images are converted to base64 data URLs and embedded directly
2. Custom Upload Service - Images are uploaded to your server and URLs are stored

Base64 Mode (Default)

By default, images are converted to base64. No configuration needed:

<PubwaveEditor />

Custom Upload Service

Configure a custom upload handler to upload images to your server:

<PubwaveEditor
  imageUpload={{
    handler: async (file: File) => {
      const formData = new FormData();
      formData.append('image', file);

      const response = await fetch('/api/upload', {
        method: 'POST',
        body: formData,
      });

      const data = await response.json();
      return data.url; // Return the image URL
    },
    maxSize: 5 * 1024 * 1024, // 5MB (optional, default: 10MB)
    accept: ['image/jpeg', 'image/png', 'image/webp'], // Optional, default: ['image/*']
  }}
/>

Image Upload Features

• File Picker: Use /image command in slash menu to open file picker
• Paste Support: Paste images from clipboard (Ctrl/Cmd+V)
• Automatic Fallback: If custom upload fails, automatically falls back to base64
• File Validation: Validates file type and size before upload
• Error Handling: Logs errors to console if upload fails

Custom Upload Service

The handler function receives a File object and should return a Promise that resolves to the image URL. The editor will automatically fall back to base64 if the upload fails.

<PubwaveEditor
  imageUpload={{
    handler: async (file: File) => {
      // Upload to your server (Cloudinary, AWS S3, etc.)
      const formData = new FormData();
      formData.append('image', file);

      const response = await fetch('/api/upload', {
        method: 'POST',
        body: formData,
      });

      const data = await response.json();
      return data.url; // Return the image URL
    },
    maxSize: 10 * 1024 * 1024, // 10MB (optional)
    accept: ['image/jpeg', 'image/png', 'image/webp'], // Optional
  }}
/>

🎨 Theming

Pubwave Editor supports full theme customization through the theme prop. You can customize colors, backgrounds, and more.

Basic Theme Configuration

import { PubwaveEditor } from '@pubwave/editor';
import type { EditorTheme } from '@pubwave/editor';

const theme: EditorTheme = {
  colors: {
    background: '#ffffff',
    text: '#1f2937',
    textMuted: '#6b7280',
    border: '#e5e7eb',
    primary: '#3b82f6',
  },
};

<PubwaveEditor theme={theme} />;

For complete EditorTheme interface definition, see TypeScript definitions. Key properties:

• colors - Color configuration (background, text, border, primary, linkColor)
• locale - Locale code for internationalization
• backgroundImage - Optional background image URL
• backgroundImageOptions - Background image display options (size, position, repeat, attachment)

Predefined Themes

The editor includes several predefined themes:

Light Theme

const lightTheme: EditorTheme = {
  colors: {
    background: 'linear-gradient(135deg, #ffffff 0%, #f8fafc 100%)',
    text: '#1f2937',
    textMuted: '#6b7280',
    border: '#e5e7eb',
    primary: '#3b82f6',
  },
};

Dark Theme

const darkTheme: EditorTheme = {
  colors: {
    background: 'linear-gradient(135deg, #0f172a 0%, #1e293b 100%)',
    text: '#f1f5f9',
    textMuted: '#94a3b8',
    border: '#334155',
    primary: '#60a5fa',
    linkColor: '#3b82f6',
  },
};

Other themes: Violet, Rose, Sky (gradient themes).

Background Image

You can add a background image to the editor container:

<PubwaveEditor
  theme={{
    colors: {
      background: '#ffffff',
      text: '#1f2937',
    },
    backgroundImage: 'https://example.com/background.jpg',
    backgroundImageOptions: {
      size: 'cover',
      position: 'center',
      repeat: 'no-repeat',
      attachment: 'fixed',
    },
  }}
/>

Background Image Options:

• size: 'cover' (default) | 'contain' | custom CSS value (e.g., '100% 100%')
• position: CSS position value (default: 'center')
• repeat: 'no-repeat' (default) | 'repeat' | 'repeat-x' | 'repeat-y'
• attachment: 'scroll' (default) | 'fixed' | 'local'

Note: The background image will be layered on top of the background color. If you want the image to be the only background, set background: 'transparent' in the colors.

Internationalization (i18n)

Pubwave Editor supports multiple languages through the locale option in the theme configuration. The editor defaults to English ('en').

Supported Locales

The following locale codes are supported:

• 'en' - English (default)
• 'zh' - Chinese
• 'zh-CN' - Simplified Chinese
• 'ja' - Japanese
• 'ko' - Korean
• 'fr' - French
• 'de' - German
• 'es' - Spanish
• 'pt' - Portuguese

Note: Currently, only English translations are fully implemented. Other languages will fall back to English. The framework is ready for future language additions.

Setting the Locale

import { PubwaveEditor } from '@pubwave/editor';
import type { EditorTheme } from '@pubwave/editor';

const theme: EditorTheme = {
  locale: 'en', // Default, can be set to any supported locale
  colors: {
    background: '#ffffff',
    text: '#1f2937',
    primary: '#3b82f6',
  },
};

<PubwaveEditor theme={theme} />;

The locale affects all user-facing text in the editor, including:

• Slash command menu items and descriptions
• Toolbar button labels and tooltips
• Accessibility labels (ARIA)
• Block type labels
• Placeholder text

CSS Custom Properties

The editor also uses CSS custom properties for styling. Define these in your CSS:

:root {
  --pubwave-bg: #ffffff;
  --pubwave-text: #1a1a1a;
  --pubwave-text-muted: #6b7280;
  --pubwave-border: #e5e7eb;
  --pubwave-primary: #3b82f6;
  --pubwave-hover: rgba(0, 0, 0, 0.05);
}

Inline Tags

Pubwave Editor supports inline tag marks in content JSON.

Supported attributes:

• variant: 'soft' | 'outline' | 'solid'
• tone: 'primary' | 'neutral'
• size: 'sm' | 'md'
• backgroundColor: custom background color
• textColor: custom text color
• borderColor: custom border color
• spacing: trailing spacing such as '8px' or '0.5rem'

Example content:

const content = {
  type: 'doc',
  content: [
    {
      type: 'paragraph',
      content: [
        {
          type: 'text',
          text: 'Live Preview',
          marks: [
            {
              type: 'tag',
              attrs: {
                variant: 'outline',
                backgroundColor: 'rgba(20, 10, 31, 0.38)',
                textColor: '#f5f3ff',
                borderColor: '#5b21b6',
                spacing: '0.75rem',
              },
            },
          ],
        },
      ],
    },
  ],
};

You can also use the standalone Tag component outside the editor:

import { Tag } from '@pubwave/editor';

<Tag
  variant="outline"
  colors={{
    background: 'rgba(20, 10, 31, 0.38)',
    text: '#f5f3ff',
    border: '#5b21b6',
  }}
  spacing="0.75rem"
>
  Live Preview
</Tag>;

🔧 Advanced Usage

Setting Editor Width

By default, the editor takes 100% of the parent container width. You can customize the width using the width prop:

// Full width (default)
<PubwaveEditor width="100%" />

// Fixed width
<PubwaveEditor width="1200px" />

// Responsive width
<PubwaveEditor width="90vw" />
<PubwaveEditor width="calc(100% - 40px)" />

The width prop accepts any valid CSS width value. When set, it will override the default max-width constraint.

Setting Editor Height

You can control the editor's height using the height and minHeight props:

// Fixed height with scrollable content
<PubwaveEditor height="500px" />

// Minimum height (expands with content)
<PubwaveEditor minHeight="300px" />

// Combined: fixed height with minimum fallback
<PubwaveEditor
  height="600px"
  minHeight="400px"
/>

// Using viewport units
<PubwaveEditor height="80vh" />

Important Notes:

• The editor has default padding of 96px top and bottom (192px total). Your height value should account for this padding to ensure content is visible.
• For example, height="100px" would leave no space for content (100px - 192px padding = negative space).
• Recommended minimum height: At least 300px for desktop to accommodate padding and content.
• When height is set, the editor becomes a scrollable container - content will scroll vertically when it exceeds the height.
• When only minHeight is set, the editor will grow automatically with content but maintain at least the minimum height.
• Both props accept any valid CSS height value (px, vh, rem, %, etc.).

Programmatic Content Manipulation

const editorRef = useRef<EditorAPI | null>(null);

<PubwaveEditor
  ref={editorRef}
  onReady={(api) => {
    editorRef.current = api;
  }}
/>;

// Set content programmatically
editorRef.current?.setContent({
  type: 'doc',
  content: [
    {
      type: 'heading',
      attrs: { level: 1 },
      content: [{ type: 'text', text: 'Hello World' }],
    },
  ],
});

// Get content
const json = editorRef.current?.getJSON();
const html = editorRef.current?.getHTML();
const text = editorRef.current?.getText();

// Apply formatting
editorRef.current?.toggleBold();
editorRef.current?.setLink('https://example.com');

Event Handling

<PubwaveEditor
  onChange={(content) => {
    // Content changed
    console.log('New content:', content);
  }}
  onSelectionChange={() => {
    // Selection changed (toolbar may appear/disappear)
  }}
  onFocus={() => {
    // Editor gained focus
  }}
  onBlur={() => {
    // Editor lost focus
  }}
  onReady={(api) => {
    // Editor is ready, API is available
    console.log('Editor ready:', api);
  }}
/>

Read-only Mode

<PubwaveEditor editable={false} content={readOnlyContent} />

In read-only mode:

• All editing affordances are hidden
• Toolbar does not appear
• Slash commands are disabled
• Drag handles are hidden
• Content is still selectable and copyable

Custom Slash Commands

You can extend the editor with custom slash commands:

import { PubwaveEditor } from '@pubwave/editor';
import type { SlashCommand } from '@pubwave/editor';

const customCommands: SlashCommand[] = [
  {
    id: 'custom-block',
    title: 'Custom Block',
    description: 'Insert a custom block',
    icon: <CustomIcon />,
    aliases: ['custom', 'cb'],
    group: 'basic',
    action: (editor) => {
      // Your custom action
    },
  },
];

// Note: Custom slash commands require access to internal APIs
// This is an advanced feature - see source code for implementation details

📊 Chart Support

The editor includes support for interactive charts powered by Chart.js. Charts are fully editable and support multiple chart types.

Chart Types

Supported chart types:

• Bar Chart - Vertical/horizontal bars for comparisons
• Line Chart - Data trends over time

4. Save changes to update the chart

🤖 AI

Pubwave ships built-in AI integration: the AIBar — a compact floating bar — drives the flow, while the model's output streams directly into the editor as real Tiptap nodes (heading, list, table, code block, …) marked as "pending" until you Apply or Discard.

You bring the model — any OpenAI-compatible endpoint, Anthropic, Gemini, or Ollama works out of the box; you can also drop in any custom adapter.

Entry points (all open the same bar)

| Trigger | When | |---|---| | Type /ai | Anywhere in the editor | | Click the ✨ button in the bubble toolbar | Text is selected | | Press ⌘J / Ctrl+J | Always |

What it does

• Streams into the editor, not into a popover. AI's output appears in place — heading becomes a real heading, list becomes a real list, table becomes a real table — with a faded "pending" highlight while it's still in review.
• Two implicit modes based on what's selected when you open the bar:
  • Selection present → transform mode: pending range replaces the selection
  • No selection → generate mode: pending range is a new block below the cursor
• Compact floating bar carries only the controls — prompt input + Send/Stop and Apply / Discard / Try again. No context dropdowns or preset menus.
• Conversational refinement: after a reply, type "shorter" or "make it more formal" and Send — the previous output is dropped and the new one streams into the same spot, with the prior turns kept as conversation history.
• Output language follows theme.locale — Chinese editor → AI replies in Chinese, etc.
• Markdown understood: the model is asked to use standard Markdown for structured content (headings, lists, tables, code, quotes, links, marks). Pubwave parses it via Tiptap's HTML pipeline, so what lands in the doc is real schema-typed nodes.

⚠️ Phase 1 limitation: custom blocks specific to Pubwave (chart, layout, colored tag) cannot be expressed in Markdown and so cannot be produced by AI in this release. The model will fall back to a Markdown table or paragraph. A later release will add tool calling for those.

Quick start

import { PubwaveEditor, createAdapter } from '@pubwave/editor';
import type { AIConfig } from '@pubwave/editor';
import '@pubwave/editor/style.css';

const aiConfig: AIConfig = {
  adapter: createAdapter({
    provider: 'openai',
    baseURL: '/api/ai/openai',  // your server proxy (see below)
  }),
  defaultModel: 'gpt-4o-mini',
};

<PubwaveEditor ai={aiConfig} />

To turn AI off, just don't pass ai (or pass undefined). No surface appears.

Provider switch — createAdapter

createAdapter({ provider: 'openai',    baseURL, apiKey, model })
createAdapter({ provider: 'anthropic', apiKey, model, anthropicVersion })
createAdapter({ provider: 'gemini',    apiKey, model })
createAdapter({ provider: 'ollama',    baseURL, model })

The 'openai' provider covers OpenAI itself plus any OpenAI-compatible endpoint — Azure, Groq, Together, OpenRouter, DeepSeek, Moonshot, Zhipu GLM, Qwen DashScope (compat-mode), Volcengine Doubao, vLLM, LM Studio, your own proxy. Just override baseURL.

For something the union doesn't cover, use defineAIAdapter({ id, stream }) and supply your own streaming function.

Two deployment modes

A. Direct (browser → provider). Demo / local Ollama only.

adapter: createAdapter({
  provider: 'openai',
  apiKey: 'sk-...',  // ⚠️ ends up in JS bundle, anyone can DevTools it
}),

Fine for local Ollama (no key needed):

adapter: createAdapter({
  provider: 'openai',
  baseURL: 'http://localhost:11434/v1',
}),
defaultModel: 'llama3.2',

B. Server proxy (recommended for cloud providers in production).

The library ships a framework-agnostic proxy handler at @pubwave/editor/server. Use it from any Web-standard runtime (Next.js / Hono / Cloudflare Workers / Bun / Deno):

Next.js — one 3-line file covers all providers:

// app/api/ai/[...path]/route.ts
import { createAIProxyHandler } from '@pubwave/editor/server';
export const POST = createAIProxyHandler();
export const runtime = 'edge';

Hono / Bun / Deno / Cloudflare Workers:

import { createAIProxyHandler } from '@pubwave/editor/server';
const handler = createAIProxyHandler();

// Hono
app.post('/api/ai/*', (c) => handler(c.req.raw));

// Cloudflare Worker
export default {
  fetch: (req, env) => createAIProxyHandler({
    openai:    { apiKey: env.OPENAI_API_KEY },
    anthropic: { apiKey: env.ANTHROPIC_API_KEY },
    gemini:    { apiKey: env.GOOGLE_API_KEY },
  })(req),
};

Path routing (default prefix /api/ai):

| Client baseURL | Forwards to | Reads env | |---|---|---| | /api/ai/openai | ${OPENAI_BASE_URL} (default: https://api.openai.com/v1) | OPENAI_API_KEY, OPENAI_BASE_URL | | /api/ai/anthropic | ${ANTHROPIC_BASE_URL} (default: Anthropic) | ANTHROPIC_API_KEY, ANTHROPIC_BASE_URL, ANTHROPIC_VERSION | | /api/ai/gemini | ${GOOGLE_BASE_URL} (default: Gemini) | GOOGLE_API_KEY, GOOGLE_BASE_URL |

Streaming (SSE) is piped through end-to-end without buffering.

Configuring providers via env

Two env vars are needed for any non-OpenAI provider that uses the OpenAI protocol (OpenRouter, DeepSeek, Moonshot, Zhipu, 千问, Groq, etc.) — both OPENAI_API_KEY AND OPENAI_BASE_URL:

# .env (or .env.local, or system env on your platform)

# --- OpenRouter (covers OpenAI / Claude / Gemini / Llama / DeepSeek with one key) ---
OPENAI_API_KEY=sk-or-v1-...
OPENAI_BASE_URL=https://openrouter.ai/api/v1

# --- OR DeepSeek ---
# OPENAI_API_KEY=sk-...
# OPENAI_BASE_URL=https://api.deepseek.com/v1

# --- OR Zhipu GLM ---
# OPENAI_API_KEY=...
# OPENAI_BASE_URL=https://open.bigmodel.cn/api/paas/v4

# --- OR Qwen DashScope (must use compat-mode path) ---
# OPENAI_API_KEY=sk-...
# OPENAI_BASE_URL=https://dashscope.aliyuncs.com/compatible-mode/v1

# --- Anthropic Claude (native) — only the key is required ---
# ANTHROPIC_API_KEY=sk-ant-...

# --- Google Gemini (native) — only the key is required ---
# GOOGLE_API_KEY=AIza...

For a fully-annotated reference of every provider's URL + model ids, see examples/nextjs/.env.example.

Common pitfall: setting only OPENAI_API_KEY (no URL) with a non-OpenAI key. The proxy will dutifully send your OpenRouter / DeepSeek / Zhipu key to OpenAI's default endpoint, which returns 401 invalid_api_key. Always set both.

Selecting the active provider in the client

Switch baseURL on the client adapter to choose which proxy path (and therefore which env vars) take effect:

createAdapter({ provider: 'openai',    baseURL: '/api/ai/openai' })     // → OPENAI_*
createAdapter({ provider: 'anthropic', baseURL: '/api/ai/anthropic' })  // → ANTHROPIC_*
createAdapter({ provider: 'gemini',    baseURL: '/api/ai/gemini' })     // → GOOGLE_*

Vite / SPA users

Vite has no server runtime. Three options:

1. Local Ollama — direct from browser, no key needed.
2. VITE_OPENAI_API_KEY in browser — demo only, key visible to anyone.
3. Separate backend — Cloudflare Worker / Hono / Express running createAIProxyHandler. Vite app points at its URL.

See Examples for runnable code.

Disabling specific surfaces

ai={{
  adapter,
  defaultModel: '...',
  enableInSlashMenu: false,    // hide /ai
  enableInToolbar: false,      // hide ✨ in bubble toolbar
  enableKeyboardShortcut: false, // disable ⌘J
}}

Security checklist

• ❌ Never put a cloud API key (OpenAI / Anthropic / Gemini / OpenRouter / etc.) in client-side code that ships to public users. Even VITE_* / NEXT_PUBLIC_* prefixes mean "this WILL be visible in the bundle."
• ✅ Use the server proxy (createAIProxyHandler) and let env vars stay on the server.
• ✅ For paid providers, add rate-limiting / auth / quotas on your proxy. The bundled handler is intentionally minimal — wrap it.
• ✅ Local Ollama and other no-auth local servers are fine to call directly from the browser.

🐛 Troubleshooting

Common Issues

Q: Styles are not applied

• Ensure you've imported the CSS: import '@pubwave/editor/style.css'
• Check that CSS custom properties are defined

Q: Slash commands don't work

• Ensure the editor is in editable mode
• Check that you're typing / in a text block (not in code blocks)

Q: Toolbar doesn't appear

• Toolbar only appears when text is selected
• Make sure you have a non-empty selection

Q: Colors don't persist

• Text and background colors are stored as marks in the content
• Ensure you're saving the full JSON content, not just HTML

Q: Image upload doesn't work

• Check that imageUpload.handler returns a valid URL string
• Verify file size is within maxSize limit
• Check browser console for error messages
• If custom upload fails, editor will automatically fall back to base64

Q: Charts don't render

• Ensure chart.js is installed: npm install chart.js (optional peer dependency)
• Check that Chart.js is compatible (v4.x or v5.x)
• Verify chart data structure is correct
• Check browser console for errors

Q: Chart colors don't match theme

• Charts use CSS variables for colors that adapt to theme changes
• Ensure CSS custom properties are defined: --pubwave-text, --pubwave-text-muted, --pubwave-border
• Chart colors will automatically update when theme changes
