When you create a npm package, remember it might be used in a browser or a server, or even a command line utility… For each package you create, please pay attention at what it will be used for:

1. Is it going to be used as a dependency to a nodejs application that is not bundled? (e.g. command line utilities)
2. Is it going to be used as a dependency to a nodejs application that is bundled? (e.g. AWS Lambdas)
3. Is it going to be used as a dependency to a browser application (always bundled)?.

• In cases 2) and 3) you want to allow for tree shaking.
• In cases 1) and 2) you want to benefit from the "ES6"/"ES next" features supported natively by nodejs.
• In case 3) you also want to benefit from the native support of "ES6" from your browser.
