Jan 1, 2025January 2025 — Klimatbyran/garbo: Delivered foundational API enhancements and data-layer readiness, driving reliability, scalability, and business value. Key features delivered include deletion routes for resource management, a schema refactor consolidating migrations and enabling PostgreSQL integration/testing, and an API surface redesign with simplified middleware. Additional performance and data-integrity improvements were shipped, notably Redis caching integration, ETag support for optimistic concurrency, and moving to cuid identifiers to improve uniqueness. Editorial workflows were enhanced by exposing IDs for editorial use and by strengthening error handling and versioning semantics. These changes establish production readiness, enable safer deployments, and accelerate future iterations. Key features delivered: - Deletion Routes: API endpoints and routing for deleting resources implemented and stabilized across commits (21058979ff1cbcdef7f92ecaa1cdddea9ca4fa47; f4b5948d668189d22175fc3eddbd7a65a06ef8ce; 45aa788b320d07c2720420ccc31e571f0b870a0a). - Schema Refactor & PostgreSQL Integration: Consolidated schemas, unified migrations, and PostgreSQL test readiness (3c80dd5f2158282f5965993a7be77e2e74d85adf; 06481df05fbdb5ec7dce3526bc74e0174641ee04; 442ed448b347788f82185a7056a6e3a0e6bf81e6; 91ffab700880fd1e8b3ac4d14d2ae6844ef66057; b31b71ec7ce2016580f22cf1bf0a7831fca8d158; 3dc7cd73c05c95c7c4f605865340440fc83e1d1c; 9c9b5a0041fac19b0d0f298fc2d1a791256ce1c1). - API Refactor & Middleware Simplification: Cleaner API surface and streamlined middlewares (da0b830dad50028ec7a4c66fe69adc57aa676a20; 36726d0b084d028c860a4038a8453f667d847b9f). - Performance & Reliability Enhancements: Redis caching integration and related setup, plus ETag support for optimistic concurrency (8a8571fa73d5e836e146ed53dec19afb620d9915; 8c3bdf537a163841ccf7ec60bb2e3ca6aa716501; 3d430dd97589af8422c15b6bb44c56c3790b0a9b; 4d44bda0f2a182df9fa70f9a0a8283543e31c0c3). - Editorial Workflows & Error Handling: Expose IDs for editorial workflows and improved error handling and version semantics (60dff7fd3ae3cc6b9c76ba4cf8b3218774f8b92b; e9de61148d1a93223572709ce5e19605ab71d677).

Overall impact and accomplishments: - Achieved PostgreSQL readiness and consolidated data layer, enabling safer migrations and scalable data access. - Improved reliability and developer productivity through API simplification, robust error handling, and editorial tooling support. - Enhanced performance and user experience with Redis caching and ETag-based concurrency, reducing latency and collisions in concurrent edits. - Strengthened data integrity and version control capabilities with structural refactors, clearer identifiers (cuid), and improved timestamp handling. Technologies/skills demonstrated: - PostgreSQL integration and migration management; schema consolidation. - Redis caching integration and connection handling. - ETag support for optimistic concurrency. - Cuid-based identifiers for improved uniqueness. - API design improvement and middleware simplification; error handling refactor. - Emissions optimization via improved querytexts and data handling; enhanced editorial tooling.
