In March 2025, the Growi project delivered a set of API, UI, and data-model improvements that strengthen business value while stabilizing the platform for scale. Key features were delivered with a focus on visibility, data integrity, and user control; coupled with targeted reliability and quality improvements to reduce risk in production. Key features delivered: - API and UI enhancement: Added endpoint to return pagePath and descendantCount and enabled UI to display selected page paths as-is, improving navigability and downstream integrations. - Data model refactor: Renamed core identifiers for clarity and consistency (_id -> path, grantedPage -> selectedPage, userGroup -> userGroups), improving future maintainability and reducing semantic ambiguity. - Learnable page limit revamp: Introduced environment-configured LIMIT_LEARNABLE_PAGE_COUNT and per-assistant limit naming, with safeguards and exposed checks to prevent oversubscription of learnable pages. - AI Assistant governance: Added isDefault flag with toggle route and related UI, enabling a clear default AI assistant and streamlined user flows; included associated upsert/isDefault handling improvements. - UI/UX and quality improvements: Implemented dark mode support, enhanced internationalization (i18n) for management pages, and comprehensive code quality efforts (lint fixes, dependency updates, cleanup, and a shift toward React Hooks). Major bugs fixed and stability improvements: - Validation: Added error when more than 300 paths are included to prevent runaway requests and surface actionable errors. - Reverts and corrections: Reverted problematic changes to restore stable behavior where needed, minimizing disruption. - OpenAI and entity handling: Improved error handling when OpenAI entities are missing and stabilized test expectations. - Thread and vector store reliability: Strengthened thread validity checks on open and ensured VectorStore interactions are robust during page/thread operations. - Misc stability work: Code cleanup, removal of unused code, and test adjustments to align with model/validator changes, reducing flakiness. Overall impact and accomplishments: - Business value: Faster, safer feature delivery with clearer ownership of AI assistant configuration and page management, reducing risk in production and enabling smarter defaults for teams. - Technical execution: End-to-end improvements across API, data models, and UI, with a strong emphasis on type safety, environment-driven configuration, internationalization, and robust error handling. Technologies and skills demonstrated: - TypeScript typings and runtime conversions; explicit input validation; environment variable configuration and per-assistant settings; React Hooks-based UI modernization; i18n and accessibility improvements; linting, refactoring, and dependency maintenance; modularized messaging and AI workflow orchestration; and robust error handling across OpenAI integrations.
