Stacks Browser

Stacks Browser

Frontend/browser utilities for STX applications.

Key Paths

• Core package: storage/framework/core/browser/src/
• Auto-imports: storage/framework/browser-auto-imports.json

Authentication Composable (useAuth)

const { user, isAuthenticated, login, register, logout, token, errors, loading } = useAuth()

// Login
await login({ email: 'user@example.com', password: 'secret' })

// Register
await register({ email: 'new@example.com', password: 'secret', name: 'John' })

// Logout
await logout()

// Auth guard (redirect if not authenticated)
authGuard()              // redirect to /login
authGuard({ guest: true })  // redirect if authenticated (for login page)

API Client (Fetch)

import { Fetch, initApi } from '@stacksjs/browser'

initApi({ baseUrl: '/api', onUnauthorized: () => router.push('/login') })

const users = await Fetch.get('/users')
await Fetch.post('/users', { name: 'John' })
await Fetch.patch('/users/1', { name: 'Jane' })
await Fetch.put('/users/1', data)
await Fetch.destroy('/users/1')
Fetch.setToken('bearer-token')

Stripe Billing (Browser-Side)

import { loadCardElement, loadPaymentElement, confirmCardSetup, confirmCardPayment, confirmPayment, createPaymentMethod } from '@stacksjs/browser'

// Load Stripe Elements
const cardElement = await loadCardElement(clientSecret)
const paymentElement = await loadPaymentElement(clientSecret)

// Confirm payment
const { paymentIntent, error } = await confirmCardPayment(clientSecret, elements)
const { setupIntent, error } = await confirmCardSetup(clientSecret, elements)
const { paymentIntent, error } = await confirmPayment(elements)
const { paymentIntent, error } = await createPaymentMethod(elements)

Browser Model Loading

import { loadBrowserModels, getBrowserModel, getBrowserModelNames } from '@stacksjs/browser'

await loadBrowserModels()               // loads all models from app/Models/
const User = getBrowserModel('User')
const names = getBrowserModelNames()     // ['User', 'Post', ...]

Browser Query Builder

import { browserQuery, BrowserQueryBuilder, browserAuth, createBrowserModel, createBrowserDb } from '@stacksjs/browser'

const users = await browserQuery('users').where('active', true).get()
const db = createBrowserDb({ baseUrl: '/api' })

Utility Functions

// Date
useDateFormat(date, 'YYYY-MM-DD')
useNow()

// Formatting
formatAreaSize(sqMeters)       // '1,234 sq ft' or 'X acres'
formatDistance(miles)           // '1.5 mi' or '2,640 ft'
formatElevation(feet)          // '1,234 ft'
formatDuration(seconds)        // '2h 15m'
getRelativeTime(dateString)    // '5 minutes ago'

// Async
fetchData(fetcher, { onError, fallback })

// Random
random(size?)                  // nanoid
customAlphabet(alphabet, size) // custom nanoid


// Retry
retry(fn, { retries: 3, initialDelay: 100, backoffFactor: 2 })

// Sleep
sleep(ms), wait(ms), delay(ms)
waitUntil(condition, { interval, timeout })
waitWhile(condition, options)

// Promise
createSingletonPromise(fn)
createControlledPromise()
createPromiseLock()

Guards

• notNullish(v) — type guard for non-null/undefined
• noNull(v) — excludes null
• notUndefined(v) — excludes undefined
• isTruthy(v) — excludes falsy values

Auto-Initialization

autoInit()  // initializes all browser utilities, exposes on window.StacksBrowser

Re-exports from Composables

useDark, useFetch, useOnline, useStorage, useToggle, useDateFormat, useNow, usePreferredDark

Gotchas

• All browser utilities are auto-imported in STX templates
• initApi() must be called before using Fetch
• loadCardElement() requires Stripe.js to be loaded
• publishableKey must be set for Stripe integration
• Browser models use a different query builder than server-side models
• autoInit() exposes utilities on window.StacksBrowser
• Do NOT use document.*, window.* directly in STX templates
