处理 npm 包依赖关系的最佳方法？

Question

I am trying to breakout a couple of Vue.js components from a primary application into an npm package stored on a repository. This package can then be imported and used across two separate sites. I am using Webpack to bundle everything but have had a few queries about the layout that should be used.

Seeing that things like Vue.js and Vuex will installed as dependencies on the main application, I know that the package will have access to these once installed on the two main applications.

My primary confusion is how do I deal with dependencies that belong to the package only, do I bundle this as part of the webpack and will running npm install on the applications automatically install the 'dependencies dependencies' if you will? Is there a general standard for these things?

The simplest thing to do is list them in your dependencies section in package.json . The package manager tool you're using (usually either npm or 'yarn`) will take responsibility for deduping the dependences, so if your parent app and your subproject both have the same dependencies, you'll only end up with one copy in the final bundle.

I would strongly suggest that you be looser on version numbers in the component projects then you are in the parent project. So in the parent maybe you say the dependency is "vue": "1.2.3" and in the component project it's "vue": "^1.1.0" or something along those lines. This way the parent can control the specific versions and your component picks up the actual version from the parent.
