buildQueryString

Serialises a params object into a URL query string, with special-case handling for empty values, arrays, and nested objects.

Signature​

import { buildQueryString } from '@conduction/nextcloud-vue'

buildQueryString({ _search: 'foo', _page: 1, _limit: 20 })
// '?_search=foo&_page=1&_limit=20'

buildQueryString({})              // ''
buildQueryString({ tags: [] })    // ''

Behaviour​

Rules applied to each key/value pair, in order:

ValueResult
undefined, null, ''key is skipped
Empty array []key is skipped
Empty plain object {}key is skipped
Non-empty arrayappended once per element (e.g. tags=a&tags=b). Empty/null entries inside the array are also skipped.
Non-empty plain objectserialised via JSON.stringify (single param value). Used for _order: { field: 'asc' } and similar.
Primitivestringified via String(value).

Returns '?' + ... when any params survive, else the empty string.

Typical use​

Used inside the object-store actions to build list-endpoint URLs:

const url = `${base}/${register}/${schema}` + buildQueryString({
  _limit: 20,
  _page: 1,
  _search: 'alice',
  _order: { createdAt: 'desc' },       // JSON.stringify'd
  status: ['open', 'pending'],         // repeated param
})
