From 9e095e1a436a751b12ba3a88d4259edec2c7a259 Mon Sep 17 00:00:00 2001 From: Max Kowalski Date: Wed, 25 Jun 2025 17:46:23 +0200 Subject: [PATCH] Refactor code for improved readability and consistency - Updated formatting in SessionDetails component for better readability. - Enhanced documentation in scheduler-fixes.md to clarify issues and solutions. - Improved error handling and logging in csvFetcher.js and processingScheduler.js. - Standardized code formatting across various scripts and components for consistency. - Added validation checks for CSV URLs and transcript content to prevent processing errors. - Enhanced logging messages for better tracking of processing status and errors. --- TODO.md | 130 +++++++++++++++------------- components/MessageViewer.tsx | 19 ++-- components/SessionDetails.tsx | 4 +- docs/scheduler-fixes.md | 10 ++- lib/csvFetcher.js | 51 ++++++++--- lib/processingScheduler.js | 99 ++++++++++++++------- lib/processingScheduler.ts | 72 +++++++++++---- lib/scheduler.js | 4 +- lib/transcriptParser.js | 105 ++++++++++++++-------- pages/api/dashboard/session/[id].ts | 25 +++--- scripts/manual-triggers.js | 61 ++++++------- scripts/process_sessions.mjs | 26 ++++-- scripts/process_sessions.ts | 32 +++++-- server.js | 22 ++--- server.mjs | 28 +++--- server.ts | 26 +++--- 16 files changed, 455 insertions(+), 259 deletions(-) diff --git a/TODO.md b/TODO.md index c6dd717..b4702c7 100644 --- a/TODO.md +++ b/TODO.md @@ -2,95 +2,107 @@ ## Dashboard Integration -- [ ] **Resolve `GeographicMap.tsx` and `ResponseTimeDistribution.tsx` data simulation** -
