MODULES

everything is a module

Modules everywhere

• Your app code is written as modules

• Libraries you use are modules

• Your whole app is one big module

“The main thing that distinguishes legacy code is a lack of tests.”

- Michael Feathers

Module Learnings

• Write some code

• Export: module.exports = { say: say }

• Import: var doge = require(‘../doge’)

• Write some tests

• Compose modules into apps

• The outside world: package.json
