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.

Constructors​

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
