# Essential Checklist for Evaluating Package Dependencies

Integrating a third-party package dependency into your codebase is a significant decision that requires careful consideration. While such packages may offer solutions, they could potentially introduce complications in the future.

Below are key questions to help assess whether a package dependency justifies inclusion:

Prior to incorporating any new package, conduct thorough evaluations and secure approval from Technical leads and senior developers, confirming the package's necessity and the absence of superior alternatives.

Follow this assessment checklist:

* What **security classification** has Snyk assigned? If High or Medium risk, are we comfortable accepting this vulnerability?
    
* Is there **ongoing maintenance**? Infrequent **updates** might indicate unreliability.
    
* What is the dependency's **size** impact? If substantial and not reducible through **tree shaking**, can we accept potential performance implications?
    
* Is **documentation** comprehensive? Inadequate documentation will complicate understanding and implementation.
    
* How robust is the **user community** and what is the update frequency?
    
* What **dependencies does this package itself require**? Do these meet our evaluation criteria?
    
* What **licensing** terms apply? Is usage permitted under the current license? Is it commercial or open-source?
    

[Bundlephobia](https://bundlephobia.com/) provides a valuable resource for identifying size, download times, what dependencies \[package\] relies on and whether it is tree-shakeable.

By examining these factors, you can make well-informed choices regarding third-party package integration, thereby reducing risks and supporting long-term project viability.
