Hallmark provides a simple and efficient way to identify and flag potentially problematic JavaScript code patterns or "hallmarks." It analyzes abstract syntax trees (ASTs) generated from JavaScript code to detect specific constructs often associated with antipatterns, security vulnerabilities, or code style inconsistencies. This allows developers to proactively identify and address such issues during development, improving code quality and maintainability. It's customizable, allowing you to define your own hallmark rules.
Hallmark package downloads show a general upward trend since March 2024, with significant spikes in April, June, and July 2025. August 2025 saw a decrease, and September 2025 downloads are currently lower, likely due to incomplete monthly data. Overall growth indicates increasing package adoption.
