npm devDependencies vs dependencies
Raw
npm-deps.md

  • devDependencies are things like babel-cli and prettier or ava that you need to develop your app. If it is a command line tool or something that makes development possible, it should be here.

  • install using npm install <package> --dev or npm install <package> --save-dev to add to package.json in devDependencies

  • dependencies are packages that you are going to ship with the final product, and are required for your user to run your app, service or product.

  • install using npm install <package> or npm install <package> --save to add to package.json in dependencies

  • sometimes dependencies can also be devDependencies. Lodash is a common example of a package that is commonly used for development code (think unit tests, configuration scripts and similar) as well as front end.
