From dbdec710ef046e4b2061a1879e191ed2bb6d67c5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=E9=9B=A8=E9=9C=96=E9=93=83?= Date: Fri, 29 May 2026 20:32:58 +0800 Subject: [PATCH] refactor(storageCleaner): extract executeScript helpers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Extract two generic helpers to eliminate repetitive executeScript boilerplate: - runScript(): for size/query operations (5 functions) - runCleanScript(): for cleanup operations (5 functions) Also add CLEAN_OPTION_KEYS constant shared by formatCleaningResult and isEmptyResult. - 428 lines → 379 lines (-49 lines) - Eliminates ~100 lines of duplicated try/catch/result parsing Co-Authored-By: Claude Opus 4.8 --- src/utils/storageCleaner.ts | 432 ++++++++++++++++-------------------- 1 file changed, 192 insertions(+), 240 deletions(-) diff --git a/src/utils/storageCleaner.ts b/src/utils/storageCleaner.ts index bf2591b..53aef67 100644 --- a/src/utils/storageCleaner.ts +++ b/src/utils/storageCleaner.ts @@ -1,6 +1,11 @@ import type { CleaningResult, StorageCleanerOptions, StorageCleanResult } from '@/types/storage';
