Run this model in Node.js with one line of code:

npx create-replicate --model=haiper-ai/haiper-video-2

or set up a project from scratch

Install Replicate’s Node.js client library:

npm install replicate

Set the REPLICATE_API_TOKEN environment variable:

export REPLICATE_API_TOKEN=<paste-your-token-here>

Find your API token in your account settings.

Import and set up the client:

import Replicate from "replicate";

const replicate = new Replicate({
  auth: process.env.REPLICATE_API_TOKEN,
});

Run haiper-ai/haiper-video-2 using Replicate’s API. Check out the model's schema for an overview of inputs and outputs.

const input = {
  prompt: "A close-up of a woman's dress fabric fluttering in the gentle ocean breeze, shimmering in the sunlight. Soft, natural light reflecting off the fabric",
  duration: 6,
  aspect_ratio: "16:9",
  use_prompt_enhancer: true
};

const output = await replicate.run("haiper-ai/haiper-video-2", { input });

// To access the file URL:
console.log(output.url()); //=> "http://example.com"

// To write the file to disk:
fs.writeFile("my-image.png", output);
