- Integrated OpenAPI-generated TypeScript SDK (`sdk.gen.ts`, `types.gen.ts`, `client.gen.ts`) for API interactions.
- Refactored `authStore` tests to include storage mock reset logic with default implementations.
- Deleted legacy `config` module and replaced its usage with the new runtime-validated `app.config`.
- Removed old custom Axios `apiClient` with outdated token refresh logic.
- Cleaned up redundant crypto-related mocks in storage tests and replaced them with real encryption/decryption during testing.
- Updated Jest coverage exclusions to reflect the new file structure and generated client usage.
- Introduced Web Crypto API polyfills (`@peculiar/webcrypto`) for Node.js to enable SSR-safe cryptography utilities.
- Added Jest setup file for global mocks (e.g., `localStorage`, `sessionStorage`, and `TextEncoder/Decoder`).
- Enhanced token validation behavior in `storage` tests to reject incomplete tokens.
- Replaced runtime configuration validation with clamping using `parseIntSafe` constraints for improved reliability.
- Updated `package.json` and `package-lock.json` to include new dependencies (`@peculiar/webcrypto` and related libraries).
- Removed outdated `crypto` tests; added dedicated and structured tests for `authStore`, `storage`, and `app.config`.
- Enhanced test coverage for user and token validation, secure persistence, state management, and configuration parsing.
- Consolidated encryption and storage error handling with thorough validation to ensure SSR-safety and resilience.
- Improved runtime validations for tokens and configuration with stricter type checks and fallback mechanisms.
- Added robust validation for `user` object fields to ensure non-empty strings.
- Improved `calculateExpiry` with value range checks and warnings for invalid `expiresIn`.
- Incorporated try-catch in `initializeAuth` to log errors and prevent app crashes during auth initialization.
- Introduced SSR guards for browser APIs in `crypto` and `storage` modules.
- Enhanced resilience with improved error handling for encryption key management, token storage, and retrieval.
- Added validation for token structure and fallback mechanisms for corrupted data.
- Refactored localStorage handling with explicit availability checks for improved robustness.
- Centralized and refactored configuration management (`config`) with runtime validation for environment variables.
- Introduced utilities for secure token storage, including AES-GCM encryption and fallback handling.
- Enhanced `authStore` state management with token validation, secure persistence, and initialization from storage.
- Modularized authentication utilities and updated export structure for better maintainability.
- Improved error handling, input validation, and added detailed comments for enhanced clarity.
- 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.
