Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

🚀 Revolutionary Data Pipeline Framework

The next-generation streaming data processing library that will transform how you build scalable applications

TypeScript Performance Developer Experience

🌟 What Makes This Revolutionary?

This isn't just another data processing library. It's a paradigm shift that combines the elegance of React's component model, the power of functional programming, and the robustness of enterprise-grade systems into one unified framework.

✨ The Magic

// From this traditional approach...
const processor = new BlockProcessor()
processor.onData(async (data) => {
    try {
        const transformed = await transform(data)
        const filtered = await filter(transformed)
        await database.save(filtered)
    } catch (error) {
        // Complex error handling...
    }
})

// To this revolutionary fluent API...
Pipeline
    .fromSource(blockchainSource)
    .transform(extractTransactions)
    .filter(highValueOnly)
    .batch(100, '5s')
    .parallel(8)
    .retry(ErrorRecoveryStrategies.exponentialBackoff())
    .use(Middleware.logging())
    .use(Middleware.metrics())
    .tap(sendRealTimeAlerts)
    .to(database)
    .start()

🔥 Game-Changing Features

1. Fluent API That Reads Like English

Write data pipelines that are self-documenting and instantly understandable:

Pipeline
    .fromSource(ethereumBlocks)
    .filter(batch => batch.blocks.some(b => b.gasUsed > threshold))
    .transform(extractDeFiTransactions)
    .parallel(4) // Process with 4 workers
    .use(Middleware.rateLimit(100)) // Respect API limits
    .retry(ErrorRecoveryStrategies.forkRecovery()) // Handle blockchain reorgs
    .to(analyticsDatabase)

2. Revolutionary Middleware System

Extend functionality without touching core code:

// Built-in middleware for common patterns
.use(Middleware.logging())
.use(Middleware.metrics())
.use(Middleware.caching(1000))
.use(Middleware.rateLimit(50))

// Custom middleware for domain-specific logic
.use(customSecurityMiddleware())
.use(businessLogicMiddleware())

3. Fork and Merge Pipelines Like Git Branches

Split processing streams and merge them back:

const [ethPipeline, polygonPipeline] = pipeline.fork()

const processed = Pipeline.merge(
    ethPipeline.transform(processEthereum),
    polygonPipeline.transform(processPolygon)
).use(crossChainAnalysis())

4. Battle-Tested Error Recovery

Handle failures gracefully with sophisticated recovery strategies:

.retry(ErrorRecoveryStrategies.exponentialBackoff(5))
.retry(ErrorRecoveryStrategies.forkRecovery()) // Blockchain-specific
.retry(customRecoveryStrategy) // Your domain logic

5. Real-Time Metrics and Observability

Monitor everything out of the box:

pipeline.on('batch-processed', ({ metrics }) => {
    console.log(`
        Blocks processed: ${metrics.blocksProcessed}
        Throughput: ${metrics.throughputPerSecond}/s
        Avg processing time: ${metrics.averageProcessingTime}ms
    `)
})

🚀 Quick Start

Installation

npm install @sqd/pipeline-core

Your First Revolutionary Pipeline

import { Pipeline, Middleware, ErrorRecoveryStrategies } from '@sqd/pipeline-core'

// Create a production-ready pipeline in minutes
const pipeline = Pipeline
    .fromSource(dataSource)
    .use(Middleware.logging(console))
    .transform(data => ({ ...data, processed: true }))
    .filter(item => item.isValid)
    .batch(50, '10s') // Batch 50 items or every 10 seconds
    .parallel(4) // Use 4 concurrent workers
    .retry(ErrorRecoveryStrategies.exponentialBackoff(3))
    .to(database)

// Start with full lifecycle management
await pipeline.start({
    maxRetries: 5,
    enableMetrics: true,
    gracefulShutdownTimeoutMs: 30000
})

🏗️ Advanced Patterns

Multi-Chain Data Processing

function createMultiChainPipeline() {
    const [ethPipeline, polygonPipeline] = Pipeline
        .fromSource(combinedSource)
        .fork()

    return Pipeline
        .merge(
            ethPipeline.transform(processEthereum),
            polygonPipeline.transform(processPolygon)
        )
        .use(crossChainCorrelationMiddleware())
        .to(unifiedDatabase)
}

Real-Time Analytics

Pipeline
    .fromSource(liveDataFeed)
    .use(anomalyDetectionMiddleware())
    .tap(sendInstantAlerts) // Side effects
    .transform(calculateMetrics)
    .batch(1, '1s') // Real-time processing
    .parallel(8) // High concurrency
    .to(analyticsEngine)

Custom Middleware

function rateLimitMiddleware(requestsPerSecond: number): PipelineMiddleware {
    return {
        name: 'rate-limiter',
        async process(batch, next) {
            await enforceRateLimit(requestsPerSecond)
            return next()
        }
    }
}
