# Using yarn
yarn add @transform-in/sdk

# Using pnpm
pnpm add @transform-in/sdk

Usage

Initialize the SDK

import TransformIn from '@transform-in/sdk';

const transformIn = new TransformIn({
  api_key: 'your-api-key',
  project_id: 'your-project-id',
  // Optional: custom base URL
  // base_url: 'https://custom-api.example.com'
});

Check API Health

const health = await transformIn.checkHealth();
console.log(health.status); // 'ok' if the API is healthy

Get Image Information

const info = await transformIn.info('https://example.com/image.jpg');
if (info.success) {
  console.log(info.data);
  // {
  //   base64: 'encoded-url',
  //   url: 'https://example.com/image.jpg',
  //   type: 'image',
  //   ext: 'jpg',
  //   content_type: 'image/jpeg',
  //   width: 1200,
  //   height: 800,
  //   size: 123456
  // }
}

Get NSFW Content Detection

const nsfwInfo = await transformIn.nsfwInfo('https://example.com/image.jpg');
if (nsfwInfo.success) {
  console.log(nsfwInfo.data);
  // {
  //   drawing: 0.01,
  //   hentai: 0.02,
  //   neutral: 0.95,
  //   porn: 0.01,
  //   sexy: 0.01
  // }
}

Generate Transformation URL

const transformationUrl = transformIn.url('https://example.com/image.jpg', {
  w: 300,       // Width
  h: 200,       // Height
  f: 'webp',    // Format
  q: 80,        // Quality (1-100)
  bl: 5         // Blur
});

// Use this URL in your <img> tags or for direct access
console.log(transformationUrl);
// https://api.transform.in.net/transformation/your-project-id/your-api-key/encoded-url/w:300,h:200,f:webp,q:80,bl:5

Prepare Transformation (Background Processing)

// Trigger transformation without waiting for completion
const preparation = await transformIn.prepareTransformation(
  'https://example.com/image.jpg',
  {
    w: 300,
    h: 200,
    f: 'webp',
    q: 80
  }
);

if (preparation.success) {
  console.log(preparation.data.message); // "Transformation is being processed"
}

// Or wait for the transformation to complete
const completedPreparation = await transformIn.prepareTransformation(
  'https://example.com/image.jpg',
  {
    w: 300,
    h: 200,
    f: 'webp',
    q: 80
  },
  true // Set to true to wait for completion
);

if (completedPreparation.success) {
  console.log(completedPreparation.data.message); // "Transformation processed"
}

Generate Video Transformation URL

const videoTransformationUrl = transformIn.url('https://example.com/video.mp4', {
  w: 640,       // Width
  h: 360,       // Height
  f: 'mp4',     // Format (currently only mp4 is supported for video)
  q: 80         // Quality (1-100)
});

// Use this URL in your <video> tags or for direct access
console.log(videoTransformationUrl);
// https://api.transform.in.net/transformation/your-project-id/your-api-key/encoded-url/w:640,h:360,f:mp4,q:80

Prepare Video Transformation

// Video transformations are typically processed asynchronously
const videoPreparation = await transformIn.prepareTransformation(
  'https://example.com/video.mp4',
  {
    w: 640,
    h: 360,
    f: 'mp4',
    q: 80
  }
);

if (videoPreparation.success) {
  console.log(videoPreparation.data.message); // "Transformation is being processed"
}

// For larger videos, it's recommended to use the asynchronous approach
// and check the status later rather than waiting for completion

Transformation Options

Option	Description	Type	Example	Supported Media
w	Width in pixels	number	w: 300	Images, Videos
h	Height in pixels	number	h: 200	Images, Videos
f	Output format	string	f: 'webp'	Images: webp, jpg, png, etc. Videos: mp4
q	Quality (1-100)	number	q: 80	Images, Videos
bl	Blur amount	number	bl: 5	Images, Videos

Error Handling

All methods return a response object with a success property that indicates whether the operation was successful. If success is false, the error property will contain details about the error.

try {
  const info = await transformIn.info('invalid-url');
} catch (error) {
  console.error('Error:', error.message);
}
