JS cheat sheet

Bundling

When to bundle:

• when the project's output is a website or callable script (i.e., not a library)
• when it's important to distribute the dependencies along with the project
  • this is probably most useful in cases of IIFE scripts in the browser
• when it's important to minify the project to reduce its size

When not to bundle:

• when the project's output is a library (i.e., not a website or callable script) that will be consumed by other developers
• when the project will only be used in a Node context

By "callable script" in the above lists, I mean something that's exported via the "bin" field in the project's package.json and which is installable via npm link or npm i -g.
