Mar 1, 2025Month 2025-03: Implemented a practical CI optimization for nrwl/nx by introducing a dynamic E2E test matrix driven from JSON. Replaced a static, hard-coded matrix in GitHub Actions with a dynamic matrix generated by a new prepare-matrix job, which runs a TypeScript script to produce the JSON consumed by the e2e job. This change reduces configuration drift, simplifies test configuration management, and improves CI maintainability and scalability.
