From 182cff2b1635be341ca127beaadca2849d48853d Mon Sep 17 00:00:00 2001 From: Matthew Raymer Date: Fri, 30 May 2025 09:30:34 +0000 Subject: [PATCH] fix(typescript): resolve linter violations and improve type safety - Remove unused isDev variable - Add proper type annotations for event handlers - Add explicit Promise return type for loadIndexHtml - Use unknown type for error parameters instead of any - Fix event handler parameters by prefixing unused params with underscore - Improve error handling type safety throughout the file This commit improves type safety and removes unused code while maintaining existing functionality. All TypeScript linter violations have been addressed without changing the core behavior of the application. Database paths are still broken here. Security Impact: None - changes are type-level only Testing: No functional changes, existing tests should pass --- src/electron/main.ts | 378 +++++++++++++++++++++++-------------------- 1 file changed, 199 insertions(+), 179 deletions(-) diff --git a/src/electron/main.ts b/src/electron/main.ts index c125d0ea..dd2c5823 100644 --- a/src/electron/main.ts +++ b/src/electron/main.ts @@ -72,204 +72,229 @@ try { } // Database path resolution utilities -const getAppDataPath = (): string => { - const userDataPath = app.getPath('userData');
