What is the best way to compare competing npm libraries before adding a dependency?▼

Comparing npm libraries is done by retrieving their NPMS.io scores and package metadata, allowing you to evaluate quality, popularity, and GitHub activity insights side-by-side to assess risk.

How does NPMS.io calculate package maintenance and popularity?▼

NPMS.io evaluates package maintenance and popularity by aggregating package metadata, usage statistics, and GitHub activity insights into a final score to validate reliability across projects.

Can I assess npm dependency reliability for large projects using NPMS scores?▼

Yes, you can assess dependency reliability for projects by retrieving NPMS.io health metrics, which provide an overall score and breakdowns to validate package maintenance and evolving package health.

When do I need to analyze npm package health metrics?▼

You need to analyze npm package health metrics when vetting new dependencies, selecting between competing libraries, or monitoring evolving package health over time to inform dependency choices.

Are there limitations to evaluating npm packages using only NPMS.io scores?▼

NPMS.io scores provide an aggregated view of package quality, popularity, and maintenance based on metadata and GitHub activity, but should be combined with project-specific requirements when making dependency decisions.
