Mar 1, 2026March 2026 performance snapshot for the justifi-tech/web-component-library. Focused on build process modernization, expanded test coverage, and architectural refinements to improve reliability, developer velocity, and release readiness. Key outcomes include removing pnpm-lock.yaml and streamlining dist packaging, extensive end-to-end and unit test coverage across UFC, modular checkout, tokenize payments, and payment provisioning, and major refactors consolidating core payment and dispute components into cohesive Justifi modules. Release readiness was strengthened with a version bump to 1.1.1 and a dedicated release tag 6.12.2, plus documentation improvements (CodeBlock usage, modular checkout docs) to improve developer experience and onboarding. Additional US/Canada checkout enhancements were implemented to improve compliance and reduce data-entry errors. These efforts deliver faster, safer releases, higher test confidence, and a more maintainable codebase with improved business onboarding flows.

Jan 1, 2026January 2026 monthly summary for justifi-tech/web-component-library: Key features delivered include the deprecation/redesign of Business Form and Payment Provisioning components to align with the new strategy, with documentation cleanup (removal) and future-direction updates, followed by a rollback to preserve stability. Additionally, the Web Component Library documentation and UX were significantly enhanced with framework-agnostic guidance, improved version display, complete code samples, updated event/method references, and localization support. Dispute notification component styling was strengthened with consistent CSS ::part theming to enable external theming and maintainability. Major fixes and reliability improvements encompassed comprehensive documentation accuracy updates across 16 MDX files (corrected event/method names, added missing events, removed non-existent methods) and a rollback of unintended documentation deletions to ensure stability. Overall, these efforts reduce technical debt, improve cross-framework developer experience, and better align with the product strategy. Technologies/skills demonstrated include documentation engineering (MDX/markdown), cross-framework guidance, dynamic versioning, CSS ::part theming, localization, and rigorous commit hygiene.
