SieveResponseStrategy

src/strategies/sieve-response.strategy.ts4 public methodsclass

Response strategy for the Sieve (.NET) driver

Sieve itself does not define a response envelope — it returns an IQueryable that the ASP.NET developer wraps in a paging DTO of their choosing. This strategy therefore ships a sensible default mapping for the common hand-rolled PagedResult<T> shape:

{
  "data": [{ "id": 1, "title": "Hello" }],
  "page": 2,
  "pageSize": 10,
  "total": 48,
  "totalPages": 5
}

Every key path is configurable through Config.response (dot notation supported), so any wrapper shape — { items, meta: {...} }, { results, pagination: {...} } — can be mapped without subclassing. Defaults are encoded in SieveResponseOptions. from/to are computed from page × pageSize by the inherited traversal algorithm, and the navigation-URL slots resolve to undefined unless paths are provided.

The dot-notation traversal is inherited from AbstractDotPathResponseStrategy; this class exists so DriverEnum.SIEVE resolves to a distinct identity at the DI layer.

Constructor

new SieveResponseStrategy()

Methods

paginate()

paginate(response: RawResponse, options: ResponseOptions): PaginatedCollection<T>

Parse a nested-envelope pagination response into a PaginatedCollection

Parameter	Type	Description
response	RawResponse	The raw API response object
options	ResponseOptions	The response key name configuration (dot-notation paths supported)

Returns — A typed PaginatedCollection instance

resolve()

resolve(response: RawResponse, path: string): unknown

Resolve a value from a response object using a dot-notation path

Supports both flat keys ('data') and nested paths ('meta.totalItems').

Parameter	Type	Description
response	RawResponse	The raw response object
path	string	The dot-notation path to resolve

Returns — The resolved value, or undefined if any segment is missing

resolveFrom()

resolveFrom(response: RawResponse, options: ResponseOptions, currentPage: number, perPage?: number): number | undefined

Resolve the “from” index value

If options.from resolves to a value in the response, use it. Otherwise compute (currentPage - 1) * perPage + 1 when both are known.

Parameter	Type	Description
response	RawResponse	The raw response object
options	ResponseOptions	The response key name configuration
currentPage	number	The current page number
perPage	number	The number of items per page

Returns — The “from” index, or undefined when neither path nor inputs suffice

resolveTo()

resolveTo(response: RawResponse, options: ResponseOptions, currentPage: number, perPage?: number, total?: number): number | undefined

Resolve the “to” index value

If options.to resolves to a value in the response, use it. Otherwise compute Math.min(currentPage * perPage, total) when all three are known.

Parameter	Type	Description
response	RawResponse	The raw response object
options	ResponseOptions	The response key name configuration
currentPage	number	The current page number
perPage	number	The number of items per page
total	number	The total number of items

Returns — The “to” index, or undefined when neither path nor inputs suffice
