storage/framework/core/collections/src/storage/framework/core/collections/src/index.ts@stacksjs/collectionsThe package re-exports collect from ts-collect:
import { collect } from '@stacksjs/collections'
import { collect } from '@stacksjs/collections'
// Basic operations
const result = collect([1, 2, 3, 4, 5])
.filter(n => n > 2)
.map(n => n * 2)
.toArray()
// [6, 8, 10]
// Aggregation
collect([10, 20, 30]).sum() // 60
collect([10, 20, 30]).avg() // 20
collect([10, 20, 30]).min() // 10
collect([10, 20, 30]).max() // 30
// Grouping
collect(users).groupBy('role')
// { admin: [...], user: [...] }
// Sorting
collect(items).sortBy('price').toArray()
collect(items).sortByDesc('price').toArray()
// Unique
collect([1, 2, 2, 3, 3]).unique().toArray() // [1, 2, 3]
// First / Last
collect([1, 2, 3]).first() // 1
collect([1, 2, 3]).last() // 3
// Chunk
collect([1, 2, 3, 4, 5]).chunk(2).toArray()
// [[1, 2], [3, 4], [5]]
// Pluck
collect(users).pluck('name').toArray() // ['Alice', 'Bob']
// Contains
collect([1, 2, 3]).contains(2) // true
// Reduce
collect([1, 2, 3]).reduce((sum, n) => sum + n, 0) // 6
The ts-collect library provides a comprehensive Laravel Collection-compatible API including:

collect from ts-collect, no custom additions@stacksjs/arrays may be more appropriatecollect() if neededUse for headless browser QA on Stacks applications — navigation, screenshots, responsive testing, console/network monitoring, and accessibility snapshots. Dependency-free: drives a system browser over the Chrome DevTools Protocol using only Bun (no Playwright/Puppeteer). Invoke with /stacks-browse.
Use when styling components in a Stacks application — utility-first CSS classes, theming, responsive design, variants, custom rules, or CSS generation. Crosswind is the CSS utility engine powering Stacks' Crosswind config.
Use when working with UI in a Stacks application — components, composables, reactivity (refs/watch/computed), Craft native components, Crosswind CSS, Crosswind utility framework, accessibility, or the STX templating engine. Covers @stacksjs/ui, @stacksjs/stx, and related UI tooling.
Use when building, modifying, or debugging API endpoints in a Stacks application — defining routes, handling requests, API middleware, working with the API server, HTTP client (fetcher), API resources, or OpenAPI generation. Covers both @stacksjs/api utilities and the stacks-api server implementation.
Use when working with routing in a Stacks application — defining routes, HTTP methods, route groups, middleware, named routes, URL generation, request enhancement (Laravel-style input/query/file helpers), response helpers, error responses, route model binding, or rate limiting. Covers @stacksjs/router, routes/, and app/Routes.ts.
Use when defining or organizing route files in a Stacks application — creating route files in routes/, registering them in app/Routes.ts, using route prefixes and middleware groups, or the default API routes structure. For the router API itself (request helpers, response helpers, middleware classes), see stacks-router.
