Jun 1, 2025June 2025 focused on strengthening developer experience and expanding the data model to support shelter tracking in the HSLdevcom/jore4-ui repo. Delivered workflow modernization to standardize local development, reduced setup time, and improved data seeding. Extended the GraphQL Shelter Information Schema to include shelter_external_id and shelter_number, enabling precise shelter data queries and analytics. No major bug fixes were reported for this period; maintenance and documentation updates ensured long-term maintainability and clearer onboarding. These efforts collectively improve developer throughput, reduce environment-related errors, and lay groundwork for enhanced reporting and data insights.

May 1, 2025May 2025: Stabilized UI deployment workflows by updating environment variable replacement tooling. Fixed the replace-environment-variables.sh script to support a new environment variable naming format and to correctly substitute values containing special characters (for example, dollar signs) in JavaScript assets, preventing misconfigurations during builds. This ensures NEXT_PUBLIC_DIGITRANSIT_API_KEY is reliably replaced across the codebase, reducing deployment risks and post-deploy hotfixes.
