From 26d26ab30f50fd6ef8a4a08a96b04e4b2416614f Mon Sep 17 00:00:00 2001 From: gidson5 Date: Mon, 30 Mar 2026 06:05:35 +0100 Subject: [PATCH] feat: implement Stellar Transaction History Importer module (#642) - HistoryImportJob entity (id, walletId, status, totalImported, cursor, startedAt, completedAt) with PENDING/RUNNING/COMPLETED/FAILED states - StellarHistoryImporterService with importHistory, getImportStatus, syncNewTransactions, mapHorizonTxToInternal, deduplicateByTxHash, and resumeFromCursor methods - Cursor-based Horizon pagination (200 tx/page), progress saved after each page so jobs are resumable on failure - Deduplication by txHash via stellar_transactions table with graceful fallback when table does not exist yet - HistoryImportProcessor (BullMQ WorkerHost) with 3 retries and exponential backoff - StellarHistoryImporterController: POST /wallets/:id/import-history and GET /wallets/:id/import-status - WalletVerifiedListener auto-triggers import on wallet.verified event - BullModule.forRootAsync wired into AppModule with Redis config - Unit tests (22 cases) covering all public methods with mocked Horizon SDK and repository - Added @nestjs/bullmq, bullmq, ioredis, @nestjs/event-emitter to deps --- backend/package.json | 4 + backend/src/app.module.ts | 14 +- .../dto/import-status.dto.ts | 17 + .../entities/history-import-job.entity.ts | 48 ++ .../listeners/wallet-verified.listener.ts | 27 ++ .../processors/history-import.processor.ts | 33 ++ .../stellar-history-importer.controller.ts | 46 ++ .../stellar-history-importer.module.ts | 26 ++ .../stellar-history-importer.service.ts | 333 ++++++++++++++ .../stellar-history-importer.service.spec.ts | 413 ++++++++++++++++++ 10 files changed, 960 insertions(+), 1 deletion(-) create mode 100644 backend/src/stellar-history-importer/dto/import-status.dto.ts create mode 100644 backend/src/stellar-history-importer/entities/history-import-job.entity.ts create mode 100644 backend/src/stellar-history-importer/listeners/wallet-verified.listener.ts create mode 100644 backend/src/stellar-history-importer/processors/history-import.processor.ts create mode 100644 backend/src/stellar-history-importer/stellar-history-importer.controller.ts create mode 100644 backend/src/stellar-history-importer/stellar-history-importer.module.ts create mode 100644 backend/src/stellar-history-importer/stellar-history-importer.service.ts create mode 100644 backend/src/stellar-history-importer/tests/stellar-history-importer.service.spec.ts diff --git a/backend/package.json b/backend/package.json index c486808d3..4f7d3cf53 100644 --- a/backend/package.json +++ b/backend/package.json @@ -40,6 +40,10 @@ "rxjs": "^7.8.1", "sharp": "^0.34.4", "socket.io": "^4.8.1", + "@nestjs/bullmq": "^11.0.2", + "@nestjs/event-emitter": "^3.0.1", + "bullmq": "^5.56.0", + "ioredis": "^5.6.1", "stellar-sdk": "^13.3.0", "typeorm": "^0.3.26" }, diff --git a/backend/src/app.module.ts b/backend/src/app.module.ts index 07d47df62..d5b4f6079 100644 --- a/backend/src/app.module.ts +++ b/backend/src/app.module.ts @@ -1,6 +1,7 @@ import { Module } from '@nestjs/common';
