Everything you need to build world-class upload experiences

Built for Performance

Optimized from the ground up for speed and efficiency

🎯 Problem

Traditional upload libraries are slow, bloated, and don't leverage modern browser capabilities. Users abandon slow uploads, and developers waste time optimizing.

💡 Solution

Uploadista uses streaming, chunked uploads, parallel processing, and intelligent retry strategies to maximize throughput while minimizing resource usage.

📊 Results

  • Up to 10x faster uploads with parallel chunk processing
  • Automatic connection pooling and retry with exponential backoff
  • Memory-efficient streaming for files of any size
  • Optimistic UI updates with real-time progress
App.tsx 
import { UploadistaProvider, useUpload } from '@uploadista/react';

// Wrap your app with the provider
function App() {
  return (
    <UploadistaProvider
      baseUrl="https://api.example.com"
      chunkSize={5 * 1024 * 1024} // 5MB chunks
      storeFingerprintForResuming={true}
    >
      <UploadForm />
    </UploadistaProvider>
  );
}

// Use the upload hook in components
function UploadForm() {
  const { upload, progress, status } = useUpload({
    flowId: 'optimize-flow',
    onProgress: (p) => console.log(`${p.percentage}%`),
  });

  return <input type="file" onChange={(e) => upload(e.target.files)} />;
}

Extreme Flexibility

Multi-cloud storage with a unified, type-safe API

🎯 Problem

Every cloud provider has different APIs and patterns. Switching providers or supporting multiple storage backends requires complete rewrites.

💡 Solution

Uploadista provides a single, unified API that works across S3, Azure Blob Storage, Google Cloud Storage, and local filesystem. Switch providers with a configuration change, not code changes.

📊 Results

  • Support for AWS S3, Azure Blob, GCS, and filesystem
  • Zero code changes when switching providers
  • Multi-region and multi-cloud strategies
  • Custom storage adapters for any backend
storage-config.ts 
import { s3Store } from '@uploadista/data-stores-s3';
import { azureStore } from '@uploadista/data-stores-azure';

// S3 storage for production
const prodStorage = s3Store({
  deliveryUrl: 'https://cdn.example.com',
  s3ClientConfig: {
    bucket: 'my-uploads',
    region: 'us-east-1',
    credentials: { accessKeyId: '...', secretAccessKey: '...' },
  },
});

// Azure storage for backups
const backupStorage = azureStore({
  deliveryUrl: 'https://backup.blob.core.windows.net',
  containerName: 'backups',
  connectionString: process.env.AZURE_CONNECTION,
});

// Both use the same DataStore interface
// Switch providers with config changes, not code changes

Powerful Processing

Visual flow-based processing with built-in transformations

🎯 Problem

Processing uploaded files requires complex pipelines, error handling, and coordination between multiple services. Code becomes brittle and hard to maintain.

💡 Solution

Uploadista's flow engine lets you define processing pipelines as directed acyclic graphs. Chain transformations, route based on conditions, and handle errors declaratively.

📊 Results

  • Visual flow builder for complex pipelines
  • Built-in nodes: resize, optimize, convert, validate
  • Conditional routing and parallel processing
  • Type-safe flow definitions with full IntelliSense
flows/optimize-flow.ts 
import { createFlow, createInputNode } from '@uploadista/core';
import { createResizeNode, createOptimizeNode } from '@uploadista/flow-images-nodes';
import { createStorageOutputNode } from '@uploadista/flow-output-nodes';

// Define flow as a DAG with nodes and edges
export const optimizeFlow = createFlow({
  flowId: 'optimize-flow',
  name: 'Optimize Flow',
  nodes: [
    createInputNode('input'),
    createResizeNode('resize', { width: 800, height: 600, fit: 'cover' }),
    createOptimizeNode('optimize', { quality: 85, format: 'webp' }),
    createStorageOutputNode('output'),
  ],
  edges: [
    { source: 'input', target: 'resize' },
    { source: 'resize', target: 'optimize' },
    { source: 'optimize', target: 'output' },
  ],
});

Developer Experience First

Built with TypeScript and Effect-TS for maximum productivity

🎯 Problem

Upload libraries have poor TypeScript support, unclear error messages, and lack modern development patterns. Debugging issues is painful.

💡 Solution

Uploadista is built from the ground up with TypeScript and Effect-TS. Every function is fully typed, errors are structured and actionable, and the API is designed for discoverability.

📊 Results

  • 100% TypeScript with complete type inference
  • IntelliSense for every configuration option
  • Structured error handling with Effect-TS
  • Comprehensive documentation and examples
flows/typed-flow.ts 
import { createFlow, createInputNode } from '@uploadista/core';
import { createOptimizeNode } from '@uploadista/flow-images-nodes';
import { createStorageOutputNode } from '@uploadista/flow-output-nodes';

// Fully typed flow definition with IntelliSense
export const typedFlow = createFlow({
  flowId: 'typed-flow',
  nodes: [
    createInputNode('input'),
    createOptimizeNode('optimize', {
      quality: 85,  // TypeScript knows valid options
      format: 'webp',
    }),
    createStorageOutputNode('output'),
  ],
  edges: [
    { source: 'input', target: 'optimize' },
    { source: 'optimize', target: 'output' },
  ],
});
