Also look for signs of active maintenance and consider how difficult the library would be to replace. A quick-start example or popularity alone cannot answer those questions.
Start with fit and supported environments
Identify the interaction your project needs, then check whether the library’s documentation describes that use case and its limitations. Confirm support for the exact language, runtime, framework, and platform versions in your project. Read the current support matrix and release notes: compatibility cannot be inferred from a generic installation example.

- Does the library handle the interaction you need, or does it solve a broader problem with extra complexity?
- Are supported platforms and versions stated clearly?
- Are known limitations and unsupported cases documented?
Check how integration and upgrades work
Look beyond the shortest quick-start path. The documentation should make installation, configuration, API usage, and the transition between releases understandable. Examples help show how an API is used; upgrade instructions and breaking-change notes help estimate the cost of keeping it in a real application.

- Can you configure the library for your intended use without relying on undocumented behavior?
- Does the project explain breaking changes and migration steps?
- Can the library be isolated behind a small interface, or would its API spread throughout your application?
Inspect dependencies, permissions, and data access
A library brings more than its own code. Its direct and transitive dependencies can enlarge the dependency graph and add packages your team must review and maintain. OpenTelemetry’s JavaScript guidance, for example, notes that bundled auto-instrumentation packages increase dependency graph size and recommends installing individual packages when the required set is known: OpenTelemetry: Using instrumentation libraries.
Permissions deserve a separate check on Android. Android Developers states, “When you include a library, you also inherit its permission requirements.” Review which permissions an app requests, what each is used for, and what happens if a user denies access. Android’s guidance recommends requesting only permissions needed for a task: Permissions on Android.
- List direct and transitive dependencies, including optional or bundled packages.
- Determine whether the library accesses sensitive data or requires platform permissions.
- Check whether optional features can be omitted and whether denial of a permission is handled appropriately.
Verify the license for the release you plan to use
Check the license attached to the exact version you intend to install, along with the licenses of relevant dependencies. Assess those terms against your project’s intended use and distribution rather than assuming the package’s current or historical license applies to every release. Android’s dependency-upgrade guidance notes that license terms can change between releases and advises checking compatibility when upgrading: Upgrade dependency versions.
Assess maintenance and security response
Check recent releases, the project’s stated support policy, how it handles security advisories, and whether it documents breaking changes. A library’s maintenance needs do not end at installation: decide who will monitor updates, evaluate them, and apply security fixes.
Historical studies show why that work merits attention, but their figures are not current industry-wide rates. A 2017 study of more than 4,600 GitHub projects and 2,700 library dependencies reported that 81.5% of the studied systems retained outdated dependencies. In the same study’s survey, 69% of respondents who had promptly migrated away from a vulnerable dependency said they had been unaware of the vulnerability. Those findings describe the study’s projects and participants, not all software teams today: Kula et al., “Do Developers Update Their Library Dependencies?”.
Rank #3
Use documentation as evidence, not a guarantee
Useful documentation should explain the library’s purpose, installation, usage, and license. A 2018 study examined README files for 43,900 JavaScript packages drawn from npm and GitHub and found usage, installation, and license among common themes. That result describes a historical sample of JavaScript packages; it is not a universal documentation standard or proof that any particular library is suitable: Ikeda et al., “An Empirical Study on README contents for JavaScript Packages”.
When evaluating candidates, compare them against the same needs rather than treating a polished README or familiar name as proof of fit.
Quick Recap
Best Value
- Fit: Does it support the interaction and environment you actually need?
- Clarity: Are installation, configuration, API usage, and migration explained?
- Footprint: What dependencies and bundled packages will it add?
- Access: What permissions or data does it need, and why?
- Terms: Is the exact release’s license compatible with your use?
- Stewardship: Are releases, security handling, and breaking changes visible?
- Exit cost: How much application code would need to change if you replaced it?
