JsonApiRequestStrategy

Defined in: src/lib/strategies/json-api-request.strategy.ts:22

Request strategy for the JSON:API driver

Generates URIs in the JSON:API format:

  • Fields: fields[articles]=title,body&fields[people]=name
  • Filters: filter[status]=active
  • Includes: include=author,comments.author
  • Pagination: page[number]=1&page[size]=15
  • Sort: sort=-created_at,name (- prefix = DESC)

Constructors​

Constructor​

new JsonApiRequestStrategy(): JsonApiRequestStrategy

Returns​

JsonApiRequestStrategy

Inherited from​

AbstractRequestStrategy.constructor

Properties​

capabilities​

readonly capabilities: IStrategyCapabilities

Defined in: src/lib/strategies/json-api-request.strategy.ts:28

Filters, sorts, includes, per-model fields — same shape as Spatie but with bracket-style pagination

Overrides​

AbstractRequestStrategy.capabilities

Methods​

assertResource()​

protected assertResource(state): void

Defined in: src/lib/strategies/abstract-request.strategy.ts:89

Throw if the resource is not set on the state

Centralises the message that was previously copy-pasted across four of the five concrete strategies.

Parameters​

state​

IQueryBuilderState

The current query builder state

Returns​

void

Throws​

Error if state.resource is empty

Inherited from​

AbstractRequestStrategy.assertResource

baseUri()​

protected baseUri(state): string

Defined in: src/lib/strategies/abstract-request.strategy.ts:101

Compute the base path (no query string)

Parameters​

state​

IQueryBuilderState

The current query builder state

Returns​

string

The base URI without the query separator (e.g. /users or https://api.example.com/users)

Inherited from​

AbstractRequestStrategy.baseUri

buildUri()​

buildUri(state, options): string

Defined in: src/lib/strategies/abstract-request.strategy.ts:42

Compose the full request URI from the given state

Template method: validates the resource, computes the base path, delegates the per-driver query-string segments to parts(...), and joins them with the conventional ?/& separators.

Parameters​

state​

IQueryBuilderState

The current query builder state

options​

QueryBuilderOptions

The query parameter key name configuration

Returns​

string

The composed URI string

Throws​

Error if the resource is not set

Inherited from​

AbstractRequestStrategy.buildUri

join()​

protected join(base, segments): string

Defined in: src/lib/strategies/abstract-request.strategy.ts:115

Glue the base URI and the per-driver query-string segments

Returns the bare base when no segments were emitted (e.g. PostgREST in RANGE mode with no filters), otherwise joins with ? + &.

Parameters​

base​

string

The base URI from _baseUri

segments​

string[]

The query-string fragments from parts(...)

Returns​

string

The full URI

Inherited from​

AbstractRequestStrategy.join

parts()​

protected parts(state, options): string[]

Defined in: src/lib/strategies/json-api-request.strategy.ts:46

Emit JSON:API-format query-string segments in canonical order: include → fields → filters → pagination → sort

Parameters​

state​

IQueryBuilderState

The current query builder state

options​

QueryBuilderOptions

The query parameter key name configuration

Returns​

string[]

Ordered query-string fragments

Overrides​

AbstractRequestStrategy.parts

validateLimit()​

validateLimit(limit): void

Defined in: src/lib/strategies/abstract-request.strategy.ts:59

Validate that a limit value is acceptable for this driver

Default policy: positive integer. Drivers that recognise a sentinel (NestJS treats -1 as "fetch all") override this method.

Parameters​

limit​

number

The limit value to validate

Returns​

void

Throws​

If the value is not a positive integer

Inherited from​

AbstractRequestStrategy.validateLimit
