📚 API Documentation

🏗️ Classes

API & Network

Api — Static HTTP client with caching, loading indicators, and locale support

Api.setUrl('/api/v1')
Api.setHeaders({ Authorization: 'Bearer token' })

const data = await Api.get({ path: 'users' })
const result = await Api.post({ path: 'users', request: { name: 'John' } })
const updated = await Api.put({ path: 'users/123', request: { name: 'Jane' } })
await Api.delete({ path: 'users/123' })

ApiDefault — Manage default request data

const apiDefault = new ApiDefault()
apiDefault.set({ apiKey: 'key-123', version: '1.0' })
const data = apiDefault.get({ userId: '456' }) // merges with defaults

ApiHeaders — HTTP headers management

const headers = new ApiHeaders()
headers.set({ Authorization: 'Bearer token', 'X-Api-Key': 'key-123' })
const requestHeaders = headers.get({ 'Content-Type': 'application/json' })

ApiPreparation — Request lifecycle hooks

const preparation = new ApiPreparation()
preparation.set(async () => {
  // Called before request
  await refreshToken()
})
preparation.setEnd(async (response) => {
  // Called after request
  return { reset: false, data: null }
})

ApiResponse — Response caching and management

const response = new ApiResponse(apiDefault)
response.add({ path: '/users', method: 'GET', response: userData })
const cached = response.get('/users', 'GET')

ApiStatus — Track API request status

const status = new ApiStatus()
status.setStatus(200, 'OK')
status.setError('Network error')
console.log(status.getStatus()) // 200
console.log(status.getError()) // 'Network error'

Loading — Global loading indicator management

Loading.show() // show loading
Loading.hide() // hide loading
if (Loading.is()) { /* is loading */ }

Caching

Cache — Manage multiple caches with automatic invalidation

const cache = new Cache()
const data = cache.get('key', () => expensiveOperation(), [dep1, dep2])
const asyncData = await cache.getAsync('key', async () => await fetch())
cache.clear() // clear all caches

CacheItem — Low-level single cache value management

const item = new CacheItem(() => computeValue())
const value = item.getCache([dependencies])
item.clearCache()

CacheStatic — Static cache for global data

CacheStatic.set('config', configuration)
const config = CacheStatic.get('config')
CacheStatic.clear('config')

Data Storage

Cookie — Cookie management with automatic serialization

const theme = new Cookie('theme')
theme.set('dark', { age: 365 * 24 * 60 * 60 }) // 1 year
const value = theme.get('light') // with default
theme.remove()

CookieBlock — Cookie consent management

CookieBlock.set(true) // allow cookies
if (CookieBlock.isBlock()) { /* cookies blocked */ }

DataStorage — LocalStorage/SessionStorage wrapper

const storage = new DataStorage('settings')
storage.set({ theme: 'dark', lang: 'en' })
const settings = storage.get({ theme: 'light' }) // with default
storage.clear()

Hash — URL hash parameter management

Hash.set('page', 'home')
Hash.set('userId', '123')
const page = Hash.get('page', 'home')
Hash.addWatch('theme', (theme) => applyTheme(theme))
Hash.go({ page: 'products', category: 'electronics' })

const date = intl.date(new Date(), 'short') // '10/15/2024'
const relative = intl.relative(-2, 'day') // '2 days ago'
const percent = intl.percent(0.75) // '75%'

GeoFlag — Country flags management

GeoPhone — Phone codes and masks

const phone = GeoPhone.get('US')
// { phone: 1, within: 1, mask: ['+1 (***) ***-****'], value: 'US' }
const info = GeoPhone.getByPhone('+14155551234')
// detect country by phone number
const list = GeoPhone.getList() // all phone codes

🎯 Usage Examples

Caching Expensive Operations

import { Cache } from '@dxtmisha/functional-basic'

const cache = new Cache()
let userId = 1

// Data is cached on first call
const userData = cache.get(
  'user-data',
  () => {
    console.log('Loading user data...')
    return fetchUserData(userId)
  },
  [userId] // dependencies for invalidation
)

// When userId changes, cache invalidates
userId = 2
const newUserData = cache.get('user-data', () => fetchUserData(userId), [userId])

Locale-Aware Formatting

import { GeoIntl } from '@dxtmisha/functional-basic'

const intl = new GeoIntl('en-US')

// Numbers
console.log(intl.number(1234567.89)) // '1,234,567.89'

// Currency
console.log(intl.currency(99.99, 'USD')) // '$99.99'

// Dates
console.log(intl.date(new Date(), 'long')) // 'October 15, 2024'

// Relative time
console.log(intl.relative(-2, 'day')) // '2 days ago'

// Plural forms
console.log(intl.plural(5, ['item', 'items'])) // '5 items'

REST API Client

import { Api } from '@dxtmisha/functional-basic'

// Setup
Api.setUrl('/api/v1')

URL Hash Management

import { Hash } from '@dxtmisha/functional-basic'

// Set parameters
Hash.set('page', 'products')
Hash.set('category', 'electronics')
Hash.set('sort', 'price')

// URL becomes: #page:products/category:electronics/sort:price

// Get parameters
const page = Hash.get('page', 'home')
const category = Hash.get('category')

// Watch for changes

• With tree-shaking: only used functions are imported
• Minimal import: ~1KB (single function)
• Dependencies: zero runtime dependencies

🎯 Tree-shaking

The library fully supports tree-shaking:

// ❌ Bad - imports entire library
import * as functional from '@dxtmisha/functional-basic'

// ✅ Good - imports only what's needed
import { toArray, forEach, Cache } from '@dxtmisha/functional-basic'

🏆 Advantages

• ✅ Full TypeScript support — TypeScript out of the box
• ✅ Zero dependencies — no external runtime dependencies
• ✅ Framework agnostic — works with any framework or vanilla JS
• ✅ Tree-shakeable — optimal bundle size
• ✅ SSR friendly — safe for server-side rendering
• ✅ Comprehensive — everything you need in one library
• ✅ Well tested — comprehensive test coverage
• ✅ Well documented — complete API documentation
• ✅ Production ready — used in production projects
• ✅ Regular updates — active development and support

📖 Difference from @dxtmisha/functional

• @dxtmisha/functional-basic: Core utilities without Vue dependencies
• @dxtmisha/functional: Includes Vue composables and reactive utilities

Use functional-basic if:

• You're not using Vue.js
• You want minimal dependencies
• You're building a library
• You need maximum compatibility

Use functional if:

• You're building a Vue.js application
• You want reactive composables
• You need Vue-specific utilities
