Building with Tambo

Detect tech stack and integrate Tambo while preserving existing patterns.

Reference Guides

Load these when you reach the relevant step or need deeper implementation details:

• Components - Load at Step 5. Generative vs interactable components, propsSchema, ComponentRenderer.
• Component Rendering - Streaming props, loading states, persistent state. Load when building custom message rendering.
• Threads and Input - Load when building custom chat UI. useTambo(), useTamboThreadInput(), userKey/userToken auth, suggestions, voice.
• Tools and Context - Load when wiring host app APIs. defineTool(), MCP servers, contextHelpers.
• CLI Reference - Load at Step 6. tambo add component library, tambo init flags, non-interactive mode.
• Skills - Mention as a next step after setup. Project-scoped agent skills via CLI and dashboard.
• Add Components to Registry - Load when registering existing app components. Analyzes props, generates Zod schemas, writes descriptions.

Shared references (components, rendering, threads, tools/context, CLI, skills) are duplicated into generative-ui so each skill works independently. add-components-to-registry is unique to this skill.

Workflow

1. Detect tech stack - Analyze package.json, lock files, project structure, monorepo layout
2. Confirm with user - Present findings, ask about preferences
3. Install dependencies - Add @tambo-ai/react and zod using the project's package manager
4. Create provider setup - Wire TamboProvider with apiKey, userKey, components
5. Create component registry - Set up lib/tambo.ts
6. Add chat UI - Install pre-built Tambo components via CLI, set up path aliases and globals.css

Step 1: Detect Tech Stack

Check these files to understand the project:

# Key files to read
package.json           # Dependencies, scripts, AND package manager
tsconfig.json          # TypeScript config, path aliases
next.config.*          # Next.js
vite.config.*          # Vite
tailwind.config.*      # Tailwind CSS
postcss.config.*       # PostCSS
src/index.* or app/    # Entry points
yarn.lock / pnpm-lock.yaml / package-lock.json  # Which package manager

Detection Checklist

Package Manager Detection

Always detect and use the project's package manager. Do not assume npm.

For monorepos, install in the correct workspace:

• Yarn: yarn workspace <app-name> add @tambo-ai/react
• pnpm: pnpm --filter <app-name> add @tambo-ai/react
• npm: npm install @tambo-ai/react -w <app-name>

Monorepo Detection

Check for monorepo indicators:

• workspaces field in root package.json
• pnpm-workspace.yaml
• turbo.json or nx.json
• Multiple package.json files in apps/ or packages/

If monorepo detected, identify which package is the web app that will use Tambo (usually in apps/web, apps/frontend, or similar).

Global Keyboard Shortcuts Detection

Check if the app captures keyboard events globally (common in drawing tools, editors, IDEs). Look for:

• document.addEventListener("keydown",...) in the codebase
• Canvas-based apps (Excalidraw, Figma-like, code editors)
• Keyboard shortcut libraries (hotkeys-js, mousetrap, etc.)

If found, the Tambo chat UI wrapper must stop event propagation (see Step 6).

Step 2: Confirm with User

Present findings including the package manager and any special concerns:

I detected your project uses:
- Framework: Next.js 14 (App Router)
- Package manager: Yarn
- Styling: Tailwind CSS
- Validation: No Zod (will need to add)
- TypeScript: Yes
- Monorepo: No
- Global keyboard shortcuts: No

Should I:
1. Install Tambo with these settings?
2. Use plain CSS instead of Tailwind for Tambo components?
3. Something else?

Step 3: Install Dependencies

Use the project's package manager (detected in Step 1):

# npm
npm install @tambo-ai/react
npm install zod  # if no Zod installed

# yarn
yarn add @tambo-ai/react
yarn add zod

# pnpm
pnpm add @tambo-ai/react
pnpm add zod

# Monorepo (install in the correct workspace)
yarn workspace <app-name> add @tambo-ai/react zod
pnpm --filter <app-name> add @tambo-ai/react zod
npm install @tambo-ai/react zod -w <app-name>

Step 4: Create Provider Setup

Next.js App Router

// app/providers.tsx
"use client";
import { TamboProvider } from "@tambo-ai/react";
import { components } from "@/lib/tambo";

export function Providers({ children }: { children: React.ReactNode }) {
  return (
    <TamboProvider
      apiKey={process.env.NEXT_PUBLIC_TAMBO_API_KEY}
      userKey="default-user"
      components={components}
    >
      {children}
    </TamboProvider>
  );
}

IMPORTANT: userKey is required for authentication. Without it, message submission fails at runtime with "authentication is not ready." Note: userKey is typed as optional in TypeScript (userKey?: string), so the compiler won't catch this — the failure is purely at runtime. In production, use a real user identifier (e.g., session ID, user ID from your auth system). For development/demo, a static string such as "default-user" works.

// app/layout.tsx
import { Providers } from "./providers";

export default function RootLayout({ children }) {
  return (
    <html>
      <body>
        <Providers>{children}</Providers>
      </body>
    </html>
  );
}

Next.js Pages Router

// pages/_app.tsx
import { TamboProvider } from "@tambo-ai/react";
import { components } from "@/lib/tambo";

export default function App({ Component, pageProps }) {
  return (
    <TamboProvider
      apiKey={process.env.NEXT_PUBLIC_TAMBO_API_KEY}
      userKey="default-user"
      components={components}
    >
      <Component {...pageProps} />
    </TamboProvider>
  );
}

Vite / CRA

// src/main.tsx
import { TamboProvider } from "@tambo-ai/react";
import { components } from "./lib/tambo";
import App from "./App";

ReactDOM.createRoot(document.getElementById("root")!).render(
  <TamboProvider
    apiKey={import.meta.env.VITE_TAMBO_API_KEY}
    userKey="default-user"
    components={components}
  >
    <App />
  </TamboProvider>,
);

Step 5: Create Component Registry

// lib/tambo.ts (or src/lib/tambo.ts)
import { TamboComponent } from "@tambo-ai/react";

export const components: TamboComponent[] = [
  // Components will be registered here
];

Step 6: Add Chat UI

Pick the right chat layout for the app:

Choose based on the app's layout. If there's a sidebar or dashboard layout, use panel. If the chat should float over existing content, use collapsible. If the whole page is the chat, use full.

npx tambo add message-thread-panel --yes
# Or: npx tambo add message-thread-collapsible --yes
# Or: npx tambo add message-thread-full --yes

# With other package managers:
# yarn dlx tambo add <component> --yes
# pnpm dlx tambo add <component> --yes

After tambo add, complete the setup:

1. CSS setup — tambo add adds Tailwind directives and CSS variables to your project's CSS entry file. The file it modifies depends on the framework: If your entry file already imports a CSS file, tambo add modifies that file in place. No new import is needed.

- Next.js: app/globals.css (or src/app/globals.css) — already imported in layout by default. - Vite: src/index.css (or index.css) — already imported in main.tsx by default.

1. Path alias — Tambo components use @/ imports. Check if the project's tsconfig already has @/* in its paths. Many Next.js projects created with create-next-app have this, but not all (e.g., Cal.com uses ~/* and @components/* instead). If @/* is missing, add it to the app tsconfig (tsconfig.app.json when present, otherwise tsconfig.json): {"compilerOptions": {"paths": {"@/*": ["./src/*"]}}} If the project has no src/ directory and components land in the project root, use ["./*"] instead of ["./src/*"]. Check where tambo add placed the components to determine the correct path. For Vite projects, also add the alias to vite.config.ts: // vite.config.ts import path from "path"; export default defineConfig({resolve: {alias: {"@": path.resolve(__dirname, "src"),},},});

Keyboard Event Isolation

Critical for apps with global keyboard shortcuts (drawing tools, editors, terminal-like apps). Without this, typing in the Tambo chat input triggers the host app's shortcuts.

Wrap the Tambo chat UI in a div that stops keyboard event propagation:

<div
  onKeyDown={(e) => e.stopPropagation()}
  onKeyUp={(e) => e.stopPropagation()}
>
  {/* Use whichever component you installed */}
  <MessageThreadCollapsible />{" "}
  {/* or <MessageThreadPanel /> or <MessageThreadFull /> */}
</div>

Z-Index for Full-Screen Apps

Apps with full-screen canvases or overlays may render on top of the Tambo chat. The MessageThreadCollapsible component uses position: fixed, but the host app's canvas may have a higher stacking context. Wrap with a fixed container that sits above everything:

<div
  style={{ position: "fixed", inset: 0, zIndex: 9999, pointerEvents: "none" }}
>
  <div style={{ pointerEvents: "auto" }}>
    {/* Use whichever component you installed */}
    <MessageThreadCollapsible />{" "}
    {/* or <MessageThreadPanel /> or <MessageThreadFull /> */}
  </div>
</div>

The outer div creates a stacking context above the canvas, while pointerEvents: none/auto ensures only the chat panel is clickable — the rest of the screen passes clicks through to the canvas.

You can combine keyboard isolation and z-index in one wrapper.

Adapting to Existing Patterns

No Tailwind? Use Plain CSS

If the project doesn't use Tailwind, tambo add will install Tailwind v4 via PostCSS alongside the existing styling. This is additive — it won't break existing CSS/SCSS. The Tambo components use Tailwind, but the rest of your app keeps its styling.

If you'd prefer to avoid Tailwind entirely:

# Skip --yes flag to customize styling during add
npx tambo add message-thread-full
# Select "CSS Modules" or "Plain CSS" when prompted

Existing Validation Library?

If using Yup/Joi instead of Zod, user can either:

1. Add Zod just for Tambo schemas (recommended - small addition)
2. Convert schemas (more work, not recommended)

Monorepo?

Run commands from the web app package, not the monorepo root.

Run npx tambo init --project-name=<app-name> from the web app directory. This opens the browser for authentication and polls until the user completes auth (up to 15 minutes). Use a long timeout. Once auth completes, the CLI creates the project and writes the API key to .env.local.

Monorepo gotchas:

• Env vars: tambo init creates .env.local in the current directory. Vite loads env from envDir (check vite.config.*). Ensure the env file is where Vite looks for it.
• Dependency hoisting: Some package managers hoist deps to the monorepo root. If Vite can't resolve a Tambo dependency, install it at the root level too (e.g., yarn add -W @tambo-ai/react).
• Path aliases: Vite resolves from the vite.config.* directory. The @/ alias must resolve to the correct src/ directory within the workspace, not the monorepo root.

Environment Variables

npx tambo init --project-name=<name> opens the browser and polls until the user authenticates (up to 15 minutes). Use a long timeout. Once auth completes, it creates the project and writes .env.local.

If manual setup is needed (monorepo, read-only filesystem), add the appropriate variable:

Verification

After setup, verify by creating a simple test:

import { useTambo } from "@tambo-ai/react";

function TestComponent() {
  const { thread, isIdle } = useTambo();
  console.log("Tambo connected:", isIdle);
  return <div>Tambo is set up!</div>;
}
