What is the best way to manage dependencies and libraries when porting code?

由人工智能和领英社区提供技术支持

Porting code from one operating system to another can be a challenging task, especially when it comes to managing dependencies and libraries. Dependencies are external components that your code relies on, such as frameworks, libraries, or modules. Libraries are collections of reusable code that provide specific functionality, such as encryption, compression, or networking. When you port code, you need to ensure that your dependencies and libraries are compatible with the target operating system, and that you can access them without errors or conflicts. In this article, we will discuss some best practices for managing dependencies and libraries when porting code.

1 Choose portable dependencies

One of the best ways to avoid dependency issues when porting code is to choose dependencies that are portable, meaning that they can run on multiple operating systems without major modifications. Portable dependencies are usually written in a cross-platform language, such as C, Java, Python, or Ruby, and use standard interfaces and protocols. Some examples of portable dependencies are OpenSSL, zlib, and SQLite. By using portable dependencies, you can reduce the amount of code you need to rewrite or adapt for the target operating system, and simplify the installation and configuration process.

These days all modern programming languages are portable and if we choose any open source based langauge like python, Java, node etc. they work as it is on all platforms. Consider using docker as your runtimes to avoid any type of native locking

2 Use dependency managers

Another best practice for managing dependencies when porting code is to use dependency managers, which are tools that automate the process of downloading, installing, and updating dependencies. Dependency managers can help you keep track of the versions and locations of your dependencies, and resolve any conflicts or inconsistencies. Some dependency managers also allow you to create virtual environments, which are isolated spaces where you can install and run your dependencies without affecting the rest of the system. Some examples of dependency managers are pip for Python, npm for Node.js, and Maven for Java. By using dependency managers, you can save time and avoid errors when porting code.

Use a good dependency management system like Maven , gradle etc in your apps. That allows upgrading of versions easily as per need basis. Use a central BOM, parent project to manage it securely. It takes efforts to manage and update those but that makes sure you use always the secure and latest version in apps.

3 Bundle your dependencies

A third best practice for managing dependencies when porting code is to bundle your dependencies, which means to include them in your code package or distribution. Bundling your dependencies can help you ensure that your code has access to the exact versions and configurations of the dependencies it needs, and that it does not depend on the availability or compatibility of the system libraries. Bundling your dependencies can also make your code more portable and easier to deploy, as you do not need to install or update the dependencies separately. However, bundling your dependencies can also increase the size and complexity of your code package, and introduce security or licensing issues. Therefore, you should only bundle your dependencies if they are essential, stable, and compliant.

4 Test your code

A final best practice for managing dependencies when porting code is to test your code thoroughly on the target operating system, and on different versions and configurations if possible. Testing your code can help you identify and fix any dependency issues that may arise during the porting process, such as missing, outdated, or incompatible dependencies, or dependency conflicts or errors. Testing your code can also help you verify that your code functions correctly and meets the performance and quality standards of the target operating system. You can use various tools and methods to test your code, such as unit tests, integration tests, regression tests, or debugging tools.

Having a good test coverage in pipeline helps in porting process. Our build pipelines should have good coverage in terms of unit tests, integration tests, regression tests, contract tests. If there are any compatibility issues , they get reported earlier with all this.
