Month: 2024-11. Focused on improving code quality and developer visibility in faker-js/faker. Key feature delivered: Linting Progress Visualization by introducing eslint-plugin-file-progress to surface ESLint progress during lint runs. This feature was integrated into the ESLint configuration and required an update to the pnpm-lock.yaml to include the new dependency, ensuring reproducible builds in CI. Bugs: No major bugs fixed for faker-js/faker this month. Impact: The added visibility into lint progress enables faster issue identification, reduces time-to-feedback for developers, and strengthens CI quality gates, contributing to more reliable releases and better maintainability. Notes: Work tracked under commit 2ec9c4779591a430822b159ca79d0486e9a0c545 with message "infra: show eslint progress (#3172)".
