From 2931f600b4bcd1ad7324477c91cf00be55dd7dc7 Mon Sep 17 00:00:00 2001 From: Shunsuke Hayashi Date: Mon, 26 Jan 2026 06:57:01 +0900 Subject: [PATCH] feat(artifacts): add S3-based artifact management system MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement artifact storage and distribution for θ-cycle outputs: - src/artifacts/types.ts: Artifact, ArtifactMetadata interfaces * ArtifactType enum (file, code, report, image, log, json) * SaveArtifactOptions, DownloadUrlOptions, ArtifactFilter - src/artifacts/manager.ts: S3 + DynamoDB client * save() / saveFile() - Upload to S3, store metadata in DynamoDB * getDownloadUrl() - Generate presigned URL (default: 1 hour) * get() - Retrieve artifact metadata * listBySession() / listByUser() - Query artifacts * deleteArtifact() / deleteBySession() - Cleanup * initializeTable() - DynamoDB table setup - src/artifacts/manager.test.ts: Unit tests (skeleton) - src/artifacts/index.ts: Module exports Features: - S3 storage with automatic expiration - Presigned URLs for secure downloads - DynamoDB metadata with TTL (default: 24 hours) - GSI for sessionId/userId/type queries - Session-based cleanup Co-Authored-By: Claude --- src/artifacts/index.ts | 8 + src/artifacts/manager.test.ts | 140 +++++++++++++ src/artifacts/manager.ts | 379 ++++++++++++++++++++++++++++++++++ src/artifacts/types.ts | 103 +++++++++ 4 files changed, 630 insertions(+) create mode 100644 src/artifacts/index.ts create mode 100644 src/artifacts/manager.test.ts create mode 100644 src/artifacts/manager.ts create mode 100644 src/artifacts/types.ts diff --git a/src/artifacts/index.ts b/src/artifacts/index.ts new file mode 100644 index 000000000..596c77848 --- /dev/null +++ b/src/artifacts/index.ts @@ -0,0 +1,8 @@ +/** + * 成果物管理モジュール + * + * @module artifacts + */ + +export * from "./types.js";
