Integrate the Formbricks App Survey SDK into your app using multiple options. Explore the available choices below. If you need something else, open a GitHub Discussion, and we’ll be happy to help!
Important for Self-Hosted Setups:Multi-Domain Setup: If you are using the multi-domain setup, the appUrl parameter in all SDK configurations should point to your public domain (PUBLIC_URL environment variable). This is the domain where surveys and public-facing content are served, which may be different from your admin interface domain (WEBAPP_URL).Single Domain Setup: If you are using the single domain setup, the appUrl parameter in all SDK configurations should point to your admin domain (WEBAPP_URL environment variable).

Vue.js

Learn how to use Formbricks’ React Native SDK to integrate your surveys into React Native applications.

​
Prerequisites

Before getting started, make sure you have:
  • A running web application with user authentication in your chosen framework.
  • A Formbricks account with your environment ID and API host, available in the Setup Checklist under Settings.

​
HTML

All you need to do is copy a <script> tag to your HTML head: 
<!-- START Formbricks Surveys -->
<script type="text/javascript">
!function(){
    var appUrl = "https://app.formbricks.com"; // use PUBLIC_URL if you are using multi-domain setup, otherwise use WEBAPP_URL
    var environmentId = "<your-environment-id>";
var t=document.createElement("script");t.type="text/javascript",t.async=!0,t.src=appUrl+"/js/formbricks.umd.cjs";var e=document.getElementsByTagName("script")[0];e.parentNode.insertBefore(t,e),setTimeout(function(){window.formbricks.setup({environmentId: environmentId, appUrl: appUrl})},500)}();
</script>
<!-- END Formbricks Surveys -->

Now, visit the Validate Your Setup section to verify your setup!

​
React.js

Install the Formbricks SDK using one of the following package managers: npm, pnpm, or yarn. Note that zod is required as a peer dependency and must also be installed in your project.
npm
npm install @formbricks/js zod
pnpm
pnpm add @formbricks/js zod
yarn
yarn add @formbricks/js zod
Update your App.js/ts file to initialize Formbricks.
src/App.js
// other imports
import formbricks from "@formbricks/js";

if (typeof window !== "undefined") {
  formbricks.setup({
    environmentId: "<environment-id>",
    appUrl: "<app-url>", // use PUBLIC_URL if you are using multi-domain setup, otherwise use WEBAPP_URL
  });
}

function App() {
  // your own app
}

export default App;

​
Next.js

Next.js projects use either the App Directory or the Pages Directory. Since the Formbricks SDK runs on the client side, follow these steps based on your setup:
  • App Directory: Create a new component in app/formbricks.tsx and call it in app/layout.tsx.
  • Pages Directory: Initialize Formbricks directly in _app.tsx.
Code snippets for the integration for both conventions are provided to further assist you.
npm
npm install @formbricks/js zod
pnpm
pnpm add @formbricks/js zod
yarn
yarn add @formbricks/js zod

​
App directory

app/formbricks.tsx
"use client";

import { usePathname, useSearchParams } from "next/navigation";
import { useEffect } from "react";
import formbricks from "@formbricks/js";

export default function FormbricksProvider() {
  const pathname = usePathname();
  const searchParams = useSearchParams();

  useEffect(() => {
    formbricks.setup({
      environmentId: "<environment-id>",
      appUrl: "<app-url>", // use PUBLIC_URL if you are using multi-domain setup, otherwise use WEBAPP_URL
    });
  }, []);

  useEffect(() => {
    formbricks?.registerRouteChange();
  }, [pathname, searchParams]);

  return null;
}
app/layout.tsx
// other imports
import FormbricksProvider from "./formbricks";
import { Suspense } from "react";

export default function RootLayout({
  children,
}: {
  children: React.ReactNode;
}) {
  return (
    <html lang="en">
      <Suspense>
        <FormbricksProvider />
      </Suspense>

    appUrl: "<app-url>", // use PUBLIC_URL if you are using multi-domain setup, otherwise use WEBAPP_URL
  });
}

export default function App({ Component, pageProps }: AppProps) {
  const router = useRouter();

  useEffect(() => {
    // Connect next.js router to Formbricks
    const handleRouteChange = formbricks?.registerRouteChange;
    router.events.on("routeChangeComplete", handleRouteChange);

    return () => {
      router.events.off("routeChangeComplete", handleRouteChange);
    };
  }, []);
  return <Component {...pageProps} />;

First, initialize the Formbricks SDK to run only on the client side. To track page changes, register the route change event with the Next.js router. Next, go to the Validate Your Setup section to verify your setup!

​
Vue.js

Integrating the Formbricks SDK with Vue.js is easy. We’ll ensure the SDK is only loaded and used on the client side, as it’s not meant for server-side use.
npm
npm install @formbricks/js
pnpm
pnpm add @formbricks/js
yarn
yarn add @formbricks/js
src/formbricks.js
import formbricks from "@formbricks/js";

if (typeof window !== "undefined") {
  formbricks.setup({
    environmentId: "<environment-id>",
    appUrl: "<app-url>", // use PUBLIC_URL if you are using multi-domain setup, otherwise use WEBAPP_URL
  });
}

export default formbricks;
src/main.js
// other imports
import formbricks from "@/formbricks";

const app = createApp(App);

app.use(router);

app.mount("#app");

router.afterEach((to, from) => {
  if (typeof formbricks !== "undefined") {
    formbricks.registerRouteChange();
  }
});

const config = {
  environmentId: "<environment-id>",
  appUrl: "<app-url>", // use PUBLIC_URL if you are using multi-domain setup, otherwise use WEBAPP_URL

​
Debugging Formbricks Integration

The debug mode is only available in the JavaScript SDK and works exclusively in the browser. It is not supported in mobile SDKs such as React Native, iOS, or Android.
Enabling debug mode in your browser can help troubleshoot issues with Formbricks. Here’s how to activate it and what to look for in the logs.

​
Activate Debug Mode

To enable debug mode, add ?formbricksDebug=true to your app’s URL (e.g., https://example.com?formbricksDebug=true).

​
View Debug Logs

  1. Open your browser’s developer tools:
  • Google Chrome/Edge: Press F12 or right-click and select “Inspect” > “Console”.
  • Firefox: Press F12 or right-click and select “Inspect Element” > “Console”.
  • Safari: Press Option + Command + C to open developer tools and go to the “Console” tab.

​
Common Use Cases

Debug mode is helpful for:
  • Verifying Formbricks initialization.
  • Identifying issues with survey triggers.
  • Troubleshooting unexpected behavior.

​
Debug Log Messages

Logs provide insights into:
  • API calls and responses.
  • Survey triggers and form interactions.
  • Initialization errors.
