February 2026 — Monthly performance summary for erxes/erxes. Key features delivered (business value-focused): - Form Handling and Validation Improvements: enhanced form field handling, validation logic, and UI layout; added null checks for select options, optional placeholders, fallback values, and dynamic grid span calculations; moved validateFieldValues into the forms module and cleaned up FormPreview imports for maintainability. Commits included: 986035990a..., 1b24f69cc6..., d37fe998d0... - GraphQL Federation and Tagging API Enhancements: federation support via @key directive on Channel type and new cpTagsTag mutation to enable tagging functionality. Commits: f7c975f948..., c36bd5e649... - Client Portal Ticketing Enhancements: ticket creation now uses the correct user ID and filtering supports createdBy parameter for better access control. Commit: c885696d8615... - Permissions Management Modernization: security and permissions overhaul removing legacy checks and deprecating old logic to adopt a clearer permission strategy. Commits: 3ff8045a6a..., a18da4fdddda... Major bugs fixed: - Group Validation Efficiency Improvement: optimized group validation by fetching an existing group only when both group code and ID are provided, reducing unnecessary database calls. Commit: e51df6dde7345f01a5ab9ea140ecaa377c8128c3 Overall impact and accomplishments: - Reduced database load, improved maintainability, and strengthened security posture across forms, permissions, and client-facing APIs. Enhanced GraphQL federation readiness and a smoother client portal experience. - Demonstrated end-to-end value from UI/UX improvements to backend optimizations and API enhancements, accelerating future feature delivery. Technologies and skills demonstrated: - TypeScript, GraphQL federation (@key on Channel), tRPC module organization, and targeted code refactors. - Frontend/UI patterns (dynamic grid spans, robust validation), backend performance optimization, and security/permissions modernization. - Codebase hygiene through import cleanup and de-duplication.
