Options

const mxik = createMxik({
  lang: 'ru', // 'ru' | 'uz'
  pageSize: 20,
  timeout: 10_000, // ms, 0 disables it
  cache: false, // true, or a cache implementation
  baseURL: 'https://tasnif.soliq.uz/api/cls-api',
  fetch: globalThis.fetch,
  headers: {},
})

All options are optional, the values above are the defaults.

Cache

Off by default. The catalog changes rarely, so caching saves a lot of reque
