Why collect-ts?
A living synchronization with Laravel Collections.
- 🔄 Version tracked —
laravelCollectionVersion: 12.43in package.json - 🔧 Sync infrastructure — Scripts to pull updates from Laravel's repository
- ✅ Test parity — Tests ported from Laravel's own test suite
When Laravel adds new methods, we add them. When bugs are fixed upstream, we fix them.
Installation
bash
npm install collect-tsbash
pnpm add collect-tsbash
yarn add collect-tsbash
npx jsr add @ovdlinden/collect-tsQuick Start
typescript
import { collect } from 'collect-ts'
const result = collect([1, 2, 3, 4, 5])
.filter(n => n > 2)
.map(n => n * 2)
.sum()
// => 24LazyCollection for Large Datasets
Process millions of items without loading everything into memory:
typescript
import { lazy } from 'collect-ts'
const result = lazy(hugeDataset)
.filter(item => item.active)
.map(item => item.id)
.take(100)
.all()
// Only processes what's neededTypeScript-First
Not JavaScript with types bolted on. Real TypeScript with advanced patterns:
typescript
// Type-safe property extraction
const names = collect(users).pluck('name') // Collection<string>
// Higher-order messaging with full typing
const emails = collect(users).map.email // Collection<string>
// Conditional types that infer correctly
const flat = collect([[1, 2], [3, 4]]).collapse() // Collection<number>Next Steps
