NestjsxCrudResponseStrategy

src/strategies/nestjsx-crud-response.strategy.ts4 public methodsclass

Response strategy for the @nestjsx/crud driver

Parses @nestjsx/crud’s getMany envelope:

{
  "data": [{ "id": 1, "name": "John" }],
  "count": 10,
  "total": 48,
  "page": 2,
  "pageCount": 5
}

Default key paths are configured in NestjsxCrudResponseOptions. The envelope carries no from/to indices and no navigation links, so from/to are computed from page × count by the inherited traversal algorithm and the URL slots resolve to undefined unless the consumer overrides their paths via PaginationConfig.

Note that count is the number of entities on the current page, not the requested page size — on the last page of a result set the derived from/to can underestimate. Consumers needing exact indices should compute them from the requested limit instead.

The dot-notation traversal is inherited from AbstractDotPathResponseStrategy; this class exists so DriverEnum.NESTJSX_CRUD resolves to a distinct identity at the DI layer even though the parsing logic is shared with JSON:API, NestJS, and Strapi.

Constructor

new NestjsxCrudResponseStrategy()

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
