@computesdk/s3

AWS S3 storage provider for ComputeSDK - object storage with S3-compatible API.

Installation

npm install @computesdk/s3

Usage

import { s3 } from '@computesdk/s3';

// Create storage instance
const storage = s3({
  accessKeyId: process.env.TIGRIS_STORAGE_ACCESS_KEY_ID,
  secretAccessKey: process.env.TIGRIS_STORAGE_SECRET_ACCESS_KEY,
  endpoint: 'https://t3.storage.dev'
});

// Upload a file
await storage.upload('my-bucket', 'path/to/file.txt', 'Hello, World!');

// Upload with options
await storage.upload('my-bucket', 'image.png', buffer, {
  contentType: 'image/png',
  metadata: { author: 'user-123' }
});

// Download a file
const result = await storage.download('my-bucket', 'path/to/file.txt');
console.log(Buffer.from(result.data).toString());

// Delete a file
await storage.delete('my-bucket', 'path/to/file.txt');

// List objects
const list = await storage.list('my-bucket', { prefix: 'path/to/' });
for (const obj of list.objects) {
  console.log(`${obj.key}: ${obj.size} bytes`);
}
