Resources

Resources centralize remote options, cascades, async validation, and business queries.

Register a request

import { ResourceManager } from '@formxjs/vue'

ResourceManager.register('getCities', async (params) => {
  return api.getCities(params)
})

Bind from schema

{
  id: 'city',
  type: 'select',
  label: 'City',
  optionsFrom: {
    requestKey: 'getCities',
    params: {
      province: '${province}'
    }
  }
}

Why it matters

Requests stay outside schema while schema remains declarative. The runtime can manage params, refresh, cache, debounce, retry, and diagnostics.

Advice

• Use TTL for dictionaries.
• Use debounce and latest strategy for search.
• Clear downstream values when cascade parents change.
• Keep request implementations in runtime registration, not inside schema.
