zxcvbn-typescript

The `zxcvbn-typescript` library offers a realistic and robust approach to password strength estimation, ported to TypeScript from Dan Wheeler's original zxcvbn project. It evaluates password quality by analyzing various patterns, including common words, names, dates, sequences, keyboard patterns, and leetspeak, providing a numerical score and targeted verbal feedback to guide users. The current stable version is 5.0.1. With its v5.0.0 release, the library was fully converted to TypeScript, enhancing type safety and maintainability for modern development environments. While a strict release cadence isn't defined, updates typically align with algorithm refinements or significant refactors. Its key differentiator remains its comprehensive pattern-matching capabilities, which often provide more nuanced security assessments than simpler entropy-based methods.
