Main Issues Fixed: 1. Tools Disabled on Initial Login (Required Page Refresh) Problem: After successful login, all PDF tools appeared grayed out/disabled until the user refreshed the page. Root Cause: Race condition where tools checked endpoint availability before JWT was stored in localStorage. Fix: - Implemented optimistic defaults in useEndpointConfig - assumes endpoints are enabled when no JWT exists - Added JWT availability event system (jwt-available event) to notify components when authentication is ready - Tools now remain enabled during auth initialization instead of defaulting to disabled 2. Session Lost on Page Refresh (Immediate Logout) Problem: Users were immediately logged out when refreshing the page, losing their authenticated session. Root Causes: - Spring Security form login was redirecting API calls to /login with 302 responses instead of returning JSON - /api/v1/auth/me endpoint was incorrectly in the permitAll list - JWT filter wasn't allowing /api/v1/config endpoints without authentication Fixes: - Backend: Disabled form login in v2/JWT mode by adding && !v2Enabled condition to form login configuration - Backend: Removed /api/v1/auth/me from permitAll list - it now requires authentication - Backend: Added /api/v1/config to public endpoints in JWT filter - Backend: Configured proper exception handling for API endpoints to return JSON (401) instead of HTML redirects (302) 3. Multiple Duplicate API Calls Problem: After login, /app-config was called 5+ times, /endpoints-enabled and /me called multiple times, causing unnecessary network traffic. Root Cause: Multiple React components each had their own instance of useAppConfig and useEndpointConfig hooks, each fetching data independently. Fix: - Frontend: Created singleton AppConfigContext provider to ensure only one global config fetch - Frontend: Added global caching to useEndpointConfig with module-level cache variables - Frontend: Implemented fetch deduplication with fetchCount tracking and globalFetchedSets - Result: Reduced API calls from 5+ to 1-2 per endpoint (2 in dev due to React StrictMode) Additional Improvements: CORS Configuration - Added flexible CORS configuration matching SaaS pattern - Explicitly allows localhost development ports (3000, 5173, 5174, etc.) - No hardcoded URLs in application.properties Security Handlers Integration - Added IP-based account locking without dependency on form login - Preserved audit logging with @Audited annotations Key Code Changes: Backend Files: - SecurityConfiguration.java - Disabled form login for v2, added CORS config - JwtAuthenticationFilter.java - Added /api/v1/config to public endpoints - JwtAuthenticationEntryPoint.java - Returns JSON for API requests Frontend Files: - AppConfigContext.tsx - New singleton context for app configuration - useEndpointConfig.ts - Added global caching and deduplication - UseSession.tsx - Removed redundant config checking - Various hooks - Updated to use context providers instead of direct fetching --------- Signed-off-by: dependabot[bot] <support@github.com> Signed-off-by: stirlingbot[bot] <stirlingbot[bot]@users.noreply.github.com> Co-authored-by: dependabot[bot] <49699333+dependabot[bot]@users.noreply.github.com> Co-authored-by: Ludy <Ludy87@users.noreply.github.com> Co-authored-by: EthanHealy01 <80844253+EthanHealy01@users.noreply.github.com> Co-authored-by: Ethan <ethan@MacBook-Pro.local> Co-authored-by: Anthony Stirling <77850077+Frooodle@users.noreply.github.com> Co-authored-by: stirlingbot[bot] <195170888+stirlingbot[bot]@users.noreply.github.com> Co-authored-by: ConnorYoh <40631091+ConnorYoh@users.noreply.github.com> Co-authored-by: Connor Yoh <connor@stirlingpdf.com> |

Stirling-PDF
Stirling-PDF is a robust, locally hosted web-based PDF manipulation tool using Docker. It enables you to carry out various operations on PDF files, including splitting, merging, converting, reorganizing, adding images, rotating, compressing, and more. This locally hosted web application has evolved to encompass a comprehensive set of features, addressing all your PDF requirements.
All files and PDFs exist either exclusively on the client side, reside in server memory only during task execution, or temporarily reside in a file solely for the execution of the task. Any file downloaded by the user will have been deleted from the server by that point.
