Overview

5 clean steps from signup to production. Drop in a React component, pass your agent ID, and ship a sub-500ms voice experience.

What You'll Learn

This guide shows React developers exactly how to embed AnveVoice in a Create React App, Vite, or Remix project. You will learn how to load the widget script without blocking render, wrap it in a reusable React component, pass configuration via props, and capture conversation events with a custom hook — all while respecting StrictMode and SSR constraints.

Key Points

• Loads asynchronously — zero impact on React bundle size
• Works with Create React App, Vite, Remix, and legacy setups
• Ships in under 10 minutes with sub-500ms response latency

Benefits

• Zero Bundle Impact: The widget loads asynchronously from AnveVoice's CDN. Your React bundle size, Lighthouse score, and Core Web Vitals stay exactly where they are.
• React-Native Ergonomics: Configure via props, subscribe via hooks, clean up in useEffect. No imperative DOM manipulation — everything stays idiomatic React.
• Works Everywhere React Runs: Create React App, Vite, Remix, Gatsby, Next.js, React Native Web — the integration pattern is identical across every React toolchain.

Steps

• Step 1 — Create Your AnveVoice Agent: Sign up at anvevoice.app and create a new agent. Paste your production URL so AnveVoice can crawl your React app and auto-build a knowledge base from your routes. Copy the generated agent ID — you will need it in Step 3.
• Step 2 — Load the Widget Script in index.html: Open public/index.html (CRA) or index.html (Vite) and add the AnveVoice script tag just before the closing </body> tag. The script is async and roughly 18KB gzipped, so it will not block your React bundle or Time to Interactive.
• Step 3 — Create a AnveVoiceWidget React Component: Build a thin wrapper component that reads the agent ID from props (or process.env.REACT_APP_ANVEVOICE_AGENT_ID) and calls window.AnveVoice.init inside a useEffect. Return null from the render function — the widget injects its own DOM outside your React tree.
• Step 4 — Mount the Component in Your Root Tree: Import <AnveVoiceWidget /> in App.jsx or App.tsx and render it once at the top level — never inside a routed child, otherwise it will unmount and remount on every navigation. Pass your agentId prop from an environment variable so staging and production can use different agents.
• Step 5 — Handle Conversation Events: Subscribe to window.AnveVoice.on('message', handler) inside useEffect to pipe conversation events into your analytics or CRM. Common events include conversation_started, user_said, agent_said, lead_captured, and conversation_ended. Do not forget to unsubscribe in the cleanup function.

Summary

Add voice AI to any React app in 5 steps: sign up for AnveVoice, load the widget script in index.html, mount a wrapper component inside your root tree, pass your agent ID as a prop, and listen to conversation events with a React hook.
