- Implemented security headers following OWASP 2025 recommendations, including X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, and Content-Security-Policy.
- Applied headers globally across all routes for enhanced security.
- Migrated from Next.js 15 to Next.js 16, updating all related dependencies and configurations.
- Enhanced ESLint setup with stricter rules, expanded plugin support, and improved type-aware linting options.
- Archived middleware by renaming it to `middleware.disabled.ts` for potential future use.
- Relocated `i18n` configuration files to `src/lib/i18n` for better organization.
- Removed obsolete `request.ts` and `routing.ts` files, simplifying `i18n` setup within the project.
- Added extensive tests for `i18n/utils` to validate locale-related utilities, including locale name, native name, and flag retrieval.
- Introduced a detailed `I18N_IMPLEMENTATION_PLAN.md` to document implementation phases, decisions, and recommendations for future extensions.
- Enhanced TypeScript definitions and modularity across i18n utilities for improved developer experience.
- Integrated `next-intl` for server-side and client-side i18n support.
- Added English (`en.json`) and Italian (`it.json`) localization files.
- Configured routing with locale-based subdirectories (`/[locale]/path`) using `next-intl`.
- Introduced type-safe i18n utilities and TypeScript definitions for translation keys.
- Updated middleware to handle locale detection and routing.
- Implemented dynamic translation loading to reduce bundle size.
- Enhanced developer experience with auto-complete and compile-time validation for i18n keys.
- Consolidated multi-line arguments into single lines where appropriate in `useAuth`.
- Improved spacing and readability in data processing across components (`ProfileSettingsForm`, `PasswordChangeForm`, `SessionCard`).
- Applied consistent table and markdown formatting in design system docs (e.g., `README.md`, `08-ai-guidelines.md`, `00-quick-start.md`).
- Updated code snippets to ensure adherence to Prettier rules and streamlined JSX structures.
- Extracted password reset logic into `PasswordResetConfirmContent` wrapped in `Suspense` for cleaner and more modular component structure.
- Updated ESLint config to ignore generated files and added rules for stricter code quality (`eslint-comments`, `@typescript-eslint` adjustments).
- Automated insertion of `eslint-disable` in auto-generated TypeScript files through `generate-api-client.sh`.
- Replaced unsafe `any` type casts with safer `Record<string, unknown>` type assertions for TypeScript compliance.
- Added `lint:tests` script for pre-commit test coverage checks.
- Improved `useAuth` hooks and related type guards for better runtime safety and maintainability.
- Introduced `isAPIErrorArray` type guard to improve error handling in authentication forms, replacing type assertions for better runtime safety.
- Refactored error handling logic across `RegisterForm`, `LoginForm`, `PasswordResetRequestForm`, and `PasswordResetConfirmForm` for unexpected error fallbacks.
- Updated `next.config.ts` and `.eslintrc.json` to exclude generated API client files from linting and align configuration with latest project structure.
- Added comprehensive documentation on Phase 2 completion in `IMPLEMENTATION_PLAN.md`.
- Created `generate-api-client.sh` for OpenAPI-based TypeScript client generation.
- Added `src/lib/api` with Axios-based API client, error handling utilities, and placeholder for generated types.
- Implemented Zustand-based `authStore` for user authentication and token management.
- Integrated reusable UI components (e.g., `Dialog`, `Select`, `Textarea`, `Sheet`, `Separator`, `Checkbox`) using Radix UI and utility functions.
- Established groundwork for client-server integration, state management, and modular UI development.
Implemented a full-stack template combining Next.js (frontend), FastAPI (backend), and PostgreSQL. Included Docker configurations for development and production, environment file templates, Makefile commands, and initial setup for database migrations and builds. The stack is production-ready and supports hot-reloading for local development.
