It is a common understanding that packages listed under devDependencies are typically not included in the final build. So why do we remove them for the sake of performance optimization?
For instance, there are discussions about replacing Moment.js with a lighter alternative even when Moment.js is only in devDependencies. How does this decision affect various frameworks such as Ember, React, Vue, and Angular?
devDependencies do not necessarily mean that the dependency is essential for the production environment, as it may only be required during the build process to generate a bundle for a website using webpack. This means that while the package is included in the bundle created by webpack, it is not needed by the system or server installing the package for production use.
For instance, if your package app includes moment.js in its distribution bundle, then when you install package app as a dependency in another package like server, there is no need to separately install moment.js since it is already bundled within app's distribution. In this case, you would define moment.js as a devDependency in app's package.json file.
When it comes to performance, there are different perspectives. Some may focus solely on the productivity of production code, while others prioritize the efficiency of the build system. One way to enhance performance is by eliminating redundant devDependencies, which can help streamline the build process and save time and resources for tools like npm.
