API Platform Driver

Targets API Platform — the leading REST/GraphQL framework for PHP/Symfony, with bracket-based filter syntax and the Hydra/JSON-LD collection envelope.

Configure

import { DriverEnum, provideNgQubee } from 'ng-qubee';

bootstrapApplication(AppComponent, {
  providers: [provideNgQubee({ driver: DriverEnum.API_PLATFORM })]
});

Wire format

Concern	Output
Filters (single value)	field=value (exact)
Filters (multi-value)	field[]=v1&field[]=v2 (array syntax, OR)
Filters (relation)	dot paths pass through: author.name=John
Operator filters	bracket syntax field[op]=value — see below
Sort	order[name]=desc&order[id]=asc (one param per rule)
Pagination	page=N&itemsPerPage=M

page honours IConfig.request overrides (its default matches the wire format); order and itemsPerPage are fixed API Platform conventions.

note

API Platform filters are opt-in server-side — each property only accepts the syntax whose filter (SearchFilter, RangeFilter, ExistsFilter, …) is declared on the resource. The driver emits the standard form; the server must have the matching filter enabled.

Operator filters

FilterOperatorEnum translates to API Platform's filter syntax:

import { FilterOperatorEnum } from 'ng-qubee';

qb.addFilterOperator('price', FilterOperatorEnum.GT, 100);            // price[gt]=100
qb.addFilterOperator('price', FilterOperatorEnum.BTW, 10, 50);        // price[between]=10..50
qb.addFilterOperator('title', FilterOperatorEnum.CONTAINS, 'ring');   // title[partial]=ring
qb.addFilterOperator('title', FilterOperatorEnum.ILIKE, 'Ring');      // title[ipartial]=Ring
qb.addFilterOperator('title', FilterOperatorEnum.SW, 'The');          // title[start]=The
qb.addFilterOperator('id', FilterOperatorEnum.IN, 1, 2, 3);            // id[]=1&id[]=2&id[]=3
qb.addFilterOperator('author', FilterOperatorEnum.NULL, true);        // author[exists]=false
qb.addFilterOperator('author', FilterOperatorEnum.NULL, false);       // author[exists]=true

Translation table

FilterOperatorEnum	API Platform syntax
EQ	bare exact match (field=value)
GT / GTE / LT / LTE	RangeFilter field[gt]= / [gte] / [lt] / [lte]
BTW	RangeFilter field[between]=min..max (arity-checked)
CONTAINS	SearchFilter field[partial]=
ILIKE	SearchFilter field[ipartial]= (case-insensitive)
SW	SearchFilter field[start]=
IN	array syntax field[]=v1&field[]=v2
NULL (true)	ExistsFilter field[exists]=false — inverted: exists=false ⇔ IS NULL
NULL (false)	ExistsFilter field[exists]=true
NOT	unsupported — no negation filter in core; throws UnsupportedFilterOperatorError
FTS / PHFTS / PLFTS / WFTS	unsupported — throws UnsupportedFilterOperatorError

Value shape rules

Enforced at call time — both throw InvalidFilterOperatorValueError:

• BTW requires exactly 2 values (min, max).
• NULL requires exactly 1 boolean value.

Date filtering

API Platform's DateFilter (after / before / strictly_after / strictly_before) has no FilterOperatorEnum counterpart, but the bracket key passes through addFilter directly:

qb.addFilter('createdAt[after]', '2023-01-01');   // createdAt[after]=2023-01-01

Feature matrix

Method	Supported?	Notes
addFilter / deleteFilters	✓	Exact match (single) or array-syntax OR (multi); relation dot paths pass through
addFilterOperator / deleteOperatorFilters	✓	See translation table above
addSort / deleteSorts	✓	One order[field]=dir param per rule
setLimit / setPage	✓	page + itemsPerPage
addSelect / deleteSelect	✗	No column-projection parameter (serialization groups are server-side)
addFields / deleteFields / deleteFieldsByModel	✗	No per-model field selection
addIncludes / deleteIncludes	✗	Relations embed via serialization groups, not a query param
addEmbedded / deleteEmbedded	✗	Throws UnsupportedEmbeddedError
setSearch / deleteSearch	✗	No standard global search parameter

Response shape

API Platform's default Hydra/JSON-LD collection envelope:

{
  "@context": "/contexts/Book",
  "@type": "hydra:Collection",
  "hydra:totalItems": 48,
  "hydra:member": [{ "id": 21, "title": "The Ring" }],
  "hydra:view": {
    "@id": "/books?page=3&itemsPerPage=10",
    "hydra:first": "/books?page=1",
    "hydra:previous": "/books?page=2",
    "hydra:next": "/books?page=4",
    "hydra:last": "/books?page=5"
  }
}

The body names no current-page or page-size field, so ApiPlatformResponseStrategy derives them from the hydra:view URLs:

• page from the page param of the view's @id (no view → page 1).
• perPage from the itemsPerPage param of the view's @id — echoed whenever the request set it, which this driver always does — falling back to the item count of a page that has a hydra:next successor.
• lastPage from the page param of hydra:last, falling back to ceil(total ÷ perPage).

Relative links (/books?page=4) are handled and surfaced as-is on the collection's URL slots. The Hydra key paths are configurable (dot notation supported — the colon-keys are dot-free segments):

provideNgQubee({
  driver: DriverEnum.API_PLATFORM,
  response: {
    data: 'member',
    total: 'totalItems'
  }
});

note

JSON:API and HAL serialization formats are out of scope for this driver — for API Platform's JSON:API output, use the JSON:API driver instead.

Defaults are encoded in ApiPlatformResponseOptions.
