PocketbaseRequestStrategy

Defined in: src/lib/strategies/pocketbase-request.strategy.ts:41

Request strategy for the PocketBase driver

Generates URIs in PocketBase's records-list format:

  • Filters: a single filter=(...) expression-language parameter — simple single-value filters fold to field='value', multi-value filters fold to an OR group ((field='v1' || field='v2')), and all clauses join with &&
  • Operator filters: expression terms (field>=10, field~'val') — see the mapping on _formatOperatorClause
  • Sorts: sort=-created,title (CSV, - prefix = DESC)
  • Field selection (flat): fields=id,title (CSV)
  • Relation expansion: expand=author,comments (CSV)
  • Pagination (page-based): page=N&perPage=M

The page / perPage / sort / filter / expand / fields keys are fixed by the PocketBase records API and intentionally not configurable through QueryBuilderOptions; they live as private statics so they are visible in one place.

String literals are single-quoted with embedded quotes backslash-escaped (name='O\'Brien'); numbers and booleans emit bare. PocketBase has no global search param (use ~ terms instead) and no per-model field selection — the corresponding fluent methods throw the matching Unsupported*Error. The PostgREST-native full-text operators (FTS, PHFTS, PLFTS, WFTS) throw UnsupportedFilterOperatorError.

Constructor

new PocketbaseRequestStrategy(): PocketbaseRequestStrategy

Returns

PocketbaseRequestStrategy

Inherited from

AbstractRequestStrategy.constructor

Properties

capabilities

readonly capabilities: IStrategyCapabilities

Defined in: src/lib/strategies/pocketbase-request.strategy.ts:48

Filters, operator filters, sorts, expand (includes), flat field selection (select) — no per-model fields, no global search, no embedded resources

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/pocketbase-request.strategy.ts:86

Emit PocketBase-format query-string segments in canonical order: expand → fields → filter (merged) → sort → page → perPage

Simple filters and operator filters share the single filter=(...) parameter so the server receives one combined expression rather than two conflicting filter params.

Parameters

state

IQueryBuilderState

The current query builder state

_options

QueryBuilderOptions

The query parameter key name configuration (unused; PocketBase's wire 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

Inherited from

AbstractRequestStrategy.validateLimit
