Deploying a text-to-video generation app through Vercel makes the process straightforward by providing serverless functions, global edge delivery, and seamless integration with frameworks like Next.js. In this guide, we"ll walk through the steps to prepare your app, connect it with a video generation API, and deploy it live on Vercel.

Prerequisites

Before deploying, you should have the following:

  • Codebase: A working Next.js or Node.js project for your text-to-video app.
  • Vercel Account: Sign up for free at vercel.com.
  • Git Repository: Your project should be pushed to GitHub, GitLab, or Bitbucket.
  • Environment Variables: API keys for your text-to-video provider stored securely.

Prepare Your Text-to-Video App

Before deploying to Vercel, it"s important to have a working app structure in place. Preparing your text-to-video app ensures that both the frontend (user input and video display) and they are correctly set up.

Project Setup

Initialize your Next.js app:

code
npx create-next-app@latest text-to-video-appcd text-to-video-app

Build a Minimal Frontend (UI)

Create an index.js file in your pages folder. This file will contain the UI code for the applications. Your UI only needs three core elements:

  • A text input field (prompt).
  • A Generate Video button.
  • A <video> element to display the result.
code
// pages/index.js
import { useState } from "react";

export default function Home() {
const [prompt, setPrompt] = useState("");
const [videoUrl, setVideoUrl] = useState("");

async function generateVideo() {
const res = await fetch("/api/generate", {
method: "POST",
headers: { "Content-Type": "application/json" },
body: JSON.stringify({ prompt }),
});
const data = await res.json();
setVideoUrl(data.videoUrl);
}

return (
<div>
<h1>Text-to-Video Generator</h1>
<input
type="text"
placeholder="Enter a scene description..."
value={prompt}
onChange={(e) => setPrompt(e.target.value)}
/>
<button onClick={generateVideo}>Generate Video</button>
{videoUrl && <video controls src={videoUrl} />}
</div>
);
}

Tip: Keep dependencies minimal and UI logic lean to ensure fast execution in edge environments.

Connect to the Text-to-Video API

To turn user prompts into videos, your app needs to communicate with a text-to-video provider. By connecting through a Next.js API route, the prompt entered in the frontend is securely sent to the provider"s API.??

The API then processes the request using its video generation model and returns a video URL, which your app can display in the browser. This setup keeps API keys safe and ensures smooth integration between your app and the video service.

Create an API Route

code
// pages/api/generate.js
export default async function handler(req, res) {
if (req.method !== "POST") {
return res.status(405).json({ error: "Method not allowed" });
}

const { prompt } = req.body;

try {
const response = await fetch("https://api.text-to-video-provider.com/generate", {
method: "POST",
headers: {
"Authorization": `Bearer ${process.env.API_KEY}`,
"Content-Type": "application/json",
},
body: JSON.stringify({ prompt, duration: 5 }), // e.g. 5s clip
});

const data = await response.json();
res.status(200).json({ videoUrl: data.url });
} catch (error) {
console.error(error);
res.status(500).json({ error: "Video generation failed" });
}
}

Configure Environment Variables

In development, add keys to .env.local:

code
API_KEY=your-provider-api-key

In Vercel, set environment variables in Project Settings → Environment Variables.

Note:

  • Your API key should never be hardcoded. Store it in Vercel Environment Variables instead.
  • Many text-to-video APIs generate async videos (first returning a job ID, then polling until the video is ready). You can handle this with background tasks or frontend polling.

Development Validation Locally

Start the dev server:

code
npm run dev

Verify:

  • Prompt input triggers an API call.
  • API route reaches the provider.
  • Returned video URL plays as expected.

Deploy to Vercel

Deploying to Vercel makes your app accessible to anyone through a live URL. When a user enters a prompt, it travels from the app"s frontend to the backend API route, which sends the request to the text-to-video provider.

The provider processes the prompt, generates the video, and sends back a URL. Your app then retrieves this URL and plays the generated video directly in the browser.Now you need to do:

  1. Enter a prompt in the input box. Example:
A futuristic city with flying cars at sunset
  1. Click Generate Video.
  2. After a short wait, the generated video will play directly in the browser.

Sample Output (Demo Preview):

code
<video controls autoplay width="480">
<source src="https://cdn.text-to-video-provider.com/generated/futuristic-city.mp4" type="video/mp4" />
</video>

At this point, your text-to-video app is fully functional on Vercel, you can share the live URL and anyone worldwide can try it.
