ESLint Bamboo Formatter

An ESLint formatter that produces JSON output compatible with Atlassian Bamboo's Mocha Test Parser, enabling ESLint results to be parsed and visualized in Bamboo CI. Current version 0.1.2 is stable with low release cadence. It outputs to a file (default eslint.json) instead of stdout, making it distinct from standard ESLint formatters. Supports configurable output file via ESLINT_FILE env var and optional warning-as-error via ESLINT_WARNING_AS_ERROR.
