How can I ensure compatibility between Python and Node.js dependencies in a mixed-stack application during CI/CD?

To ensure compatibility between Python and Node.js dependencies in a mixed-stack application, start by implementing a comprehensive CI/CD pipeline. When doing this, you can consider using tools like pipenv for Python and npm for Node.js to properly manage dependencies and lock the correct versions. Then, set up separate test suites for each component, running Python tests with tools like pytest and Node.js tests with Jest.

Once you've done this, integrate these tests into your CI/CD pipeline to automatically check compatibility whenever you push changes. You can also monitor for dependency updates and use tools like Dependabot to receive automated pull requests for updates. This proactive approach helps maintain compatibility and keeps your application running smoothly.
