jscs is a code style checker for JavaScript. It helps ensure consistent code formatting and style across a project by enforcing a set of rules. Think of it as a linter specifically focused on style. It integrates with many popular editors and build tools, providing real-time feedback on code style issues. While deprecated, jscs played a significant role in standardizing JavaScript code style before ESLint gained prominence, proving valuable for maintaining readability and consistency in larger projects.
The npm package jscs had frequent releases between June 2013 and April 2016. The most active months were June 2013 (12 releases) and October 2015 (8 releases). After April 2016, the release frequency significantly decreased, ceasing entirely after July 2016. There have been no releases since then as of September 13, 2025.
jscs downloads show volatility. From March 2024 to August 2025 downloads generally fluctuated between 200k and 300k, with peaks in July 2025 (384k). September 2025 shows a significant drop to 115k, but that data is incomplete.
