Mar 1, 2025March 2025 performance summary for software-mansion/live-debugger: Delivered a set of UX-focused Live Debugger improvements, routing overhauls, and robustness fixes. Key features include LiveView discovery with LvProcess model and nested LiveViews visualization in the channel dashboard; a loading spinner for collapsible event bodies with simulated large messages to reflect real-world data loads; and a comprehensive Active LiveViews UI overhaul with embedded LiveViews and improved accessibility. Implemented a routing and navigation overhaul with a dedicated Routes module and standardized URLs/parameters across dashboards. Added a Messages LiveView with a reusable Button component and capped refreshed traces to improve performance on large messages. Release patch v0.1.1 for the LiveDebugger. Fixed font rendering by adding missing font-face definitions, hardened process state retrieval, and stabilized collapsible sections across screen sizes (renaming and default non-collapsible).

Jan 1, 2025Monthly Summary — 2025-01 (software-mansion/live-debugger) Key features delivered: - LiveDebugger Detail View and Node Identification System: Added a comprehensive detail view for inspecting LiveView and LiveComponent nodes, refactored the node navigation sidebar, introduced a CID-based node ID system, and added PID/CID parsing utilities and router updates. This enables precise node inspection and stable navigation during debugging. - LiveDebugger UI Improvements and UX Enhancements: Enhanced the detail view with collapsible sections, improved display of assigns and events, introduced a friendly 'No events have been recorded yet' message, and refined mobile/desktop sidebar behavior for responsiveness. Major bugs fixed: - LiveDebugger Redirect on Deleted Node: Fixed redirect to base URL when the currently debugged node is deleted, eliminating dead references and improving navigation stability. Maintenance, Dependencies, and CI/QA Improvements: - Updated dependencies (heroicons rename, heroicons_petal integration), version bumps, session handling toggles, and CI/QA improvements including caching and tests, culminating in a release (v0.0.3). Overall impact and accomplishments: - The changes significantly improve debugging reliability and developer productivity, reduce navigation errors, accelerate issue diagnosis, and enhance CI/CD stability. This supports the 0.0.3 release and provides a solid foundation for future iterations. Technologies/skills demonstrated: - Elixir/Phoenix LiveView architecture, CID-based node identification, PID/CID parsing utilities, router updates, responsive UI design, GitHub Actions CI/CD optimization, dependency management, and test coverage for LiveView components.
