Lesson 32: Modules: require & exports

Split code across files with CommonJS.

What you'll learn

• export with module.exports = ... or exports.x = ...
• import with const x = require('./file')
• each file is its own module (own scope)
• ESM alternative: import/export with "type": "module"

Example

See examples/.

Exercise

Split a 50-line file into 3 modules.
