SieveRequestStrategy

Defined in: src/lib/strategies/sieve-request.strategy.ts:31

Request strategy for the Sieve (.NET) driver

Generates URIs in Sieve's compact expression format:

  • Filters: a single filters= parameter holding comma-joined (AND) Field{op}Value terms; multi-value terms use the pipe (OR) on the value side (status==active|pending)
  • Operator filters: translated from FilterOperatorEnum — see the mapping on _formatOperatorTerms
  • Sorts: sorts=field,-other (CSV, - prefix = DESC)
  • Pagination: page=N&pageSize=N

Sieve has no per-model field selection, no relation includes, no flat column selection, and no global search parameter — the corresponding fluent methods throw the matching Unsupported*Error. PostgREST-native full-text search operators (FTS, PHFTS, PLFTS, WFTS) throw UnsupportedFilterOperatorError.

Constructors​

Constructor​

new SieveRequestStrategy(): SieveRequestStrategy

Returns​

SieveRequestStrategy

Inherited from​

AbstractRequestStrategy.constructor

Properties​

capabilities​

readonly capabilities: IStrategyCapabilities

Defined in: src/lib/strategies/sieve-request.strategy.ts:38

Filters, operator filters, sorts — no per-model fields, no includes, no flat select, no global search (use CONTAINS / ILIKE operator filters for partial matches)

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/sieve-request.strategy.ts:72

Emit Sieve-format query-string segments in canonical order: filters → sorts → page → pageSize

Parameters​

state​

IQueryBuilderState

The current query builder state

options​

QueryBuilderOptions

The query parameter key name configuration (used for page, whose default matches the wire format; the filters / sorts / pageSize keys are 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

AbstractRequestStrategy.validateLimit
