Quick Analysis

const report = analyze('./my-project');

console.log(report.stats);     // Dependency counts
console.log(report.unused);    // Unused packages
console.log(report.issues);    // Potential problems
console.log(report.tree);      // ASCII tree

Get Dependencies

const deps = getDependencies('./my-project');

deps.dependencies       // Production deps
deps.devDependencies    // Dev deps
deps.peerDependencies   // Peer deps
deps.all                // All combined

Find Unused Dependencies

const unused = findUnused('./my-project');

console.log(unused.unused);      // ['lodash', 'moment']
console.log(unused.used);        // ['express', 'react']
console.log(unused.unusedCount); // 2

Get Statistics

const stats = getStats('./my-project');
// {
//   dependencies: 15,
//   devDependencies: 8,
//   peerDependencies: 2,
//   optionalDependencies: 0,
//   total: 25
// }
