From 4e29c8cf846fba15183ffe76ac453cfa4f2a2dbb Mon Sep 17 00:00:00 2001 From: adityagarud Date: Thu, 2 Oct 2025 13:20:10 +0530 Subject: [PATCH 1/4] feat(knowledge-bases): add waitForDatabase polling helper Add helper function to poll knowledge base database status until ONLINE state. Includes error handling for failed states, timeout protection, and configurable polling intervals. Fixes the need for manual polling loops. --- src/index.ts | 8 + .../knowledge-bases/knowledge-bases.ts | 33 ++++ .../knowledge-bases/wait-for-database.ts | 173 ++++++++++++++++++ .../knowledge-bases/wait-for-database.test.ts | 81 ++++++++ 4 files changed, 295 insertions(+) create mode 100644 src/resources/knowledge-bases/wait-for-database.ts create mode 100644 tests/resources/knowledge-bases/wait-for-database.test.ts diff --git a/src/index.ts b/src/index.ts index 0223275..397c40f 100644 --- a/src/index.ts +++ b/src/index.ts @@ -20,3 +20,11 @@ export { PermissionDeniedError, UnprocessableEntityError, } from './core/error'; + +// Export knowledge base helpers +export { + waitForDatabase, + type WaitForDatabaseOptions, + WaitForDatabaseTimeoutError, + WaitForDatabaseFailedError, +} from './resources/knowledge-bases/wait-for-database'; diff --git a/src/resources/knowledge-bases/knowledge-bases.ts b/src/resources/knowledge-bases/knowledge-bases.ts index 2f13105..1a8a7e3 100644 --- a/src/resources/knowledge-bases/knowledge-bases.ts +++ b/src/resources/knowledge-bases/knowledge-bases.ts @@ -34,6 +34,7 @@ import { import { APIPromise } from '../../core/api-promise'; import { RequestOptions } from '../../internal/request-options'; import { path } from '../../internal/utils/path'; +import { waitForDatabase } from './wait-for-database'; export class KnowledgeBases extends APIResource { dataSources: DataSourcesAPI.DataSources = new DataSourcesAPI.DataSources(this._client); @@ -135,6 +136,31 @@ export class KnowledgeBases extends APIResource { ...options, }); } + + /** + * Polls for knowledge base database creation to complete. + * + * This helper method polls the knowledge base status until the database is ONLINE, + * handling various error states and providing configurable timeout and polling intervals. + * + * @example + * ```ts + * const kb = await client.knowledgeBases.waitForDatabase('123e4567-e89b-12d3-a456-426614174000'); + * console.log('Database is ready:', kb.database_status); // 'ONLINE' + * ``` + * + * @param uuid - The knowledge base UUID to poll for + * @param options - Configuration options for polling behavior + * @returns Promise - The knowledge base with ONLINE database status + * @throws WaitForDatabaseTimeoutError - If polling times out + * @throws WaitForDatabaseFailedError - If the database enters a failed state + */ + async waitForDatabase( + uuid: string, + options?: import('./wait-for-database').WaitForDatabaseOptions + ): Promise { + return waitForDatabase(this._client, uuid, options); + } } /** @@ -422,6 +448,13 @@ export interface KnowledgeBaseListParams { KnowledgeBases.DataSources = DataSources; KnowledgeBases.IndexingJobs = IndexingJobs; +export { + waitForDatabase, + WaitForDatabaseOptions, + WaitForDatabaseTimeoutError, + WaitForDatabaseFailedError, +} from './wait-for-database'; + export declare namespace KnowledgeBases { export { type APIKnowledgeBase as APIKnowledgeBase, diff --git a/src/resources/knowledge-bases/wait-for-database.ts b/src/resources/knowledge-bases/wait-for-database.ts new file mode 100644 index 0000000..7443fd6 --- /dev/null +++ b/src/resources/knowledge-bases/wait-for-database.ts @@ -0,0 +1,173 @@ +// File generated from our OpenAPI spec by Stainless.
