  • options.resolver {(source, options) => string[]} The core method for resolving dependencies. (optional, default require('./resolver'))
  • options.returnAbsolutePath {boolean} whether returning the local module's absolute path, or use real module id instead. (optional, default true)

Examples

const { detectDep } = require('detect-dep')
const dependencies = detectDep('some code', {})

Returns any dependencies {String[]} - dependencies list
