analyze-require-default v0.2.0

analyze-require-default

Analyze require() statements of ES modules without .default.

JavaScript's module systems can be confusing sometimes, specifically the tiny differences in default exports/imports between ES modules (import/export) and commonjs (module.exports/require) syntax.

Such differences can be hard to find manually, and could potentially cause weird behaviours/bugs, and this is what this package is for!

Here's a quick example to demonstrate:

// a.js

module.exports = 1;

// b.js

export default 2;

// Import default from
import a from 'a'; // This is fine, even though we're mixing 2 different module systems
import b from 'b'; // This is fine, we're on the same module system

const a = require('a'); // This is fine, we're on the same module system
const b = require('b'); // This is NOT fine, we'll get "{ default: 2 }"

npm i -g analyze-require-default
