JavaScript Modules Importing with side effects

30% OFF - 9th Anniversary discount on Entity Framework Extensions until December 15 with code: ZZZANNIVERSARY9

Example

Sometimes you have a module that you only want to import so its top-level code gets run. This is useful for polyfills, other globals, or configuration that only runs once when your module is imported.

Given a file named test.js:

console.log('Initializing...')

You can use it like this:

import './test'

This example will print Initializing... to the console.
