To manage app dependencies, use a package manager to track and update libraries. Regularly audit your dependencies for security vulnerabilities and remove unused packages.

Effectively managing app dependencies is crucial for maintaining the stability and security of your cross-platform application. Start by using a package manager like npm or Yarn to track all your libraries and their versions. This allows you to easily update dependencies when new versions are released. Regularly audit your dependencies for security vulnerabilities using tools like npm audit or Snyk, and address any identified issues promptly. Unused packages can increase your app's size and introduce unnecessary vulnerabilities, so make a habit of reviewing and removing any dependencies that are no longer needed. Consider using tools like Dependabot to automate the process of keeping your dependencies up to date. Additionally, keep documentation of your dependencies, including their purpose and usage, to facilitate easier onboarding for new team members. By implementing these practices, you can ensure a more stable, secure, and efficient development environment.
