Methods

`Private`buildDocumentSearchParams

buildDocumentSearchParams(
    params: {
        dateFrom?: string;
        documentType?: string;
        limit?: number;
        offset?: number;
    },
): Record<string, unknown>
Private
Builds EP API parameters for document search.
Parameters
- params: { dateFrom?: string; documentType?: string; limit?: number; offset?: number }
Returns Record<string, unknown>
- Defined in clients/ep/documentClient.ts:52

clearCache

clearCache(): void
Clears all entries from the LRU cache.

Returns void
Inherited from BaseEPClient.clearCache
- Defined in clients/ep/baseClient.ts:694

`Private`filterDocuments

filterDocuments(
documents: LegislativeDocument[],
params: { committee?: string; dateTo?: string; keyword?: string },
): LegislativeDocument[]
Private
Applies client-side keyword, committee, and date-range filters to documents.
Parameters
- documents: LegislativeDocument[]
- params: { committee?: string; dateTo?: string; keyword?: string }
Returns LegislativeDocument[]
- Defined in clients/ep/documentClient.ts:85

`Protected`get

get<T extends Record<string, unknown>>(
    endpoint: string,
    params?: Record<string, unknown>,
    minimumTimeoutMs?: number,
): Promise<T>
Protected
Executes a cached, rate-limited GET request to the EP API.
Type Parameters
- T extends Record<string, unknown>
  Expected response type (extends Record<string, unknown>)
Parameters
- endpoint: string
  API endpoint path (relative to baseURL)
- Optionalparams: Record<string, unknown>
  Optional query parameters
- OptionalminimumTimeoutMs: number
  Optional per-request minimum timeout in milliseconds. When provided, the effective timeout is Math.max(minimumTimeoutMs, this.timeoutMs), so the global timeout (set via --timeout or EP_REQUEST_TIMEOUT_MS) can still extend it beyond the per-endpoint minimum. Use for known slow EP API endpoints such as procedures/feed and events/feed.
Returns Promise<T>
Promise resolving to the typed API response

Throws
On HTTP errors, network failures, or parse failures
Inherited from BaseEPClient.get
- Defined in clients/ep/baseClient.ts:626
