  credentials: "YOUR_FAL_KEY_HERE"
});

3. Generate your first image:

javascript

    prompt: "A serene mountain landscape at sunset, hyperrealistic style"
  }
});

console.log(result.images[0].url);

API Parameters

• `prompt` (required): Text description of the image to generate
• `aspect_ratio`: Control the dimensions of your generated image
• `num_images`: Number of images to generate in one request
• `seed`: Use for reproducible results
• `output_format`: Specify the desired image format

Integration Examples

Here's a practical example of generating images in a web application:

javascript
import { fal } from "@fal-ai/client";

async function generateImage(prompt, variant = "standard") {
  const modelMap = {
    standard: "fal-ai/imagen4/preview",
    fast: "fal-ai/imagen4/preview/fast",
    ultra: "fal-ai/imagen4/preview/ultra"
  };

  try {
    const result = await fal.subscribe(modelMap[variant], {
      input: { 
        prompt,
        num_images: 1
      }
    });
    return result.images[0];
  } catch (error) {
    console.error("Image generation failed:", error);
    throw error;
  }
}

Queue Management

For handling asynchronous requests:

javascript
// Submit request
const { request_id } = await fal.queue.submit("fal-ai/imagen4/preview", {
  input: {
    prompt: "Your detailed image description"
  }
});

// Check status
const status = await fal.queue.status("fal-ai/imagen4/preview", {
  requestId: request_id,
  logs: true
});

// Get result
const result = await fal.queue.result("fal-ai/imagen4/preview", {
  requestId: request_id
});
