What is detective-es6?

The detective-es6 npm package is designed to analyze JavaScript files to find and extract import/require statements. This is particularly useful for tools that need to understand dependencies between modules in ES6, CommonJS, or similar module systems. It can be used for tasks such as bundling, dependency analysis, and refactoring.

What are detective-es6's main functionalities?

Extract import statements from ES6 modules

This feature allows you to extract all import statements from a string of ES6 module code. It's useful for analyzing module dependencies.

const detective = require('detective-es6');
const src = `import { foo } from 'my-module';`;
const dependencies = detective(src);
console.log(dependencies); // Outputs: ['my-module']

Extract require statements from CommonJS modules

This feature enables the extraction of require statements from CommonJS module code, helping in the analysis of dependencies in a Node.js environment.

const detective = require('detective-es6');
const src = `const foo = require('my-module');`;
const dependencies = detective(src);
console.log(dependencies); // Outputs: ['my-module']
