What is the most effective strategy for managing dependencies for npm packages?

I am currently working on extracting a few Vue.js components from the main application and converting them into an npm package stored in a repository. This package will be imported and utilized across two different websites. To bundle everything, I am utilizing Webpack, but I have some questions regarding the appropriate layout to use.

Since Vue.js and Vuex are already dependencies of the main application, I understand that once the package is installed on the two websites, it will automatically have access to these libraries.

My main dilemma lies in how to manage dependencies specific to the package itself. Should I include them in the webpack bundling, or will running npm install on the websites automatically handle the installation of these 'dependencies of dependencies'? Is there a standard practice for handling this situation?

Answer №1

The most straightforward approach is to include the dependencies in your package.json file under the 'dependencies' section. Your package manager tool (typically either npm or 'yarn`) will handle deduplication of dependencies, ensuring that if both your main app and subproject have the same dependencies, only one copy will be included in the final bundle.

I recommend being more flexible with version numbers in your component projects compared to your main project. For instance, you could specify a dependency like 

"vue": "1.2.3"
in the main project, while using 
"vue": "^1.1.0"
in the component project. This way, the main project dictates specific versions while allowing components to adopt the actual version from the parent.
