How to Embed a HubSpot Form in Next.js and react js

HubSpot forms are widely used for lead generation, newsletters, onboarding workflows, and marketing funnels.

But when developers try to embed a HubSpot form inside a Next.js project, the default embed snippet usually fails.

Forms don’t load, scripts break, and SSR errors begin to appear.

Before implementing anything, it’s important to understand why this happens in a Next.js environment.

This article covers theory only — the actual working solution is linked at the end.

Why HubSpot Forms Don’t Work Directly in Next.js

HubSpot provides an embed script that works perfectly in standard HTML sites.

But Next.js renders pages on both the server and the client, causing conflicts.

Here’s why the embed fails:

🔹 1. HubSpot expects `window`

During SSR, window doesn’t exist — so HubSpot script breaks.

🔹 2. HubSpot injects HTML dynamically

It needs a target div in the DOM, which only exists after hydration.

🔹 3. Third-party scripts must run on the client side

If Next.js tries to execute the script on the server, errors appear.

In short:

HubSpot = browser code

Next.js = server + browser

→ The script must run only on the client.

The Actual Logic Behind the Fix (Theory Only)

Every working solution follows this exact formula:

✔ Load HubSpot’s script client-side only

Avoid SSR conflicts.

✔ Create a target container like `<div id="hubspotForm"></div>`

HubSpot needs a mount point.

✔ Initialize the form after the script loads

Timing matters because HubSpot injects content dynamically.

Once you understand this, embedding HubSpot in Next.js becomes straightforward.
