What's the difference between dependencies, devDependencies and peerDependencies in npm package.json file?

Question

This documentation answers my question very poorly. I didn\'t understand those explanations. Can someone say in simpler words? Maybe with examples if it\'s hard to choose si

Answer 1

I'd like to add to the answer my view on these dependencies explanations

• dependencies are used for direct usage in your codebase, things that usually end up in the production code, or chunks of code
• devDependencies are used for the build process, tools that help you manage how the end code will end up, third party test modules, (ex. webpack stuff)
