SpringRequestStrategy

Defined in: src/lib/strategies/spring-request.strategy.ts:25

Request strategy for the Spring Data REST driver

Generates URIs in Spring Data REST's pagination format:

  • Sorts: sort=field,asc&sort=other,desc (repeatable param, one per rule)
  • Pagination: page=N&size=Npage is 0-indexed on the wire; the library state stays 1-indexed and the strategy subtracts 1 at emission time

Spring Data REST defines no standard query parameter convention for filtering, field selection, includes, or global search — those are implemented server-side via custom query methods or Specifications. The corresponding fluent methods (addFilter, addFilterOperator, addSelect, addFields, addIncludes, setSearch) throw the matching Unsupported*Error on this driver.

Constructor

new SpringRequestStrategy(): SpringRequestStrategy

Returns

AbstractRequestStrategy.constructor

Properties

capabilities

readonly capabilities: IStrategyCapabilities

Defined in: src/lib/strategies/spring-request.strategy.ts:32

Sorts only — Spring Data REST has no standard wire convention for filters, operator filters, per-model fields, flat select, includes, or global search

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/spring-request.strategy.ts:63

Emit Spring-format query-string segments in canonical order: sort → page → size

Parameters

state

IQueryBuilderState

The current query builder state

options

QueryBuilderOptions

The query parameter key name configuration (used for page and sort, whose defaults match the wire format; the size key is fixed by the server)

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
