Methods

Sync vs Async vs Async/Await

Most methods are async by default. All async methods will return a promise if the callback isn't passed.

Sync methods on the other hand will throw if an error occurs.

Also Async/Await will throw an error if one occurs.

Sync

• findPackageJsonSync
• installSync
• uninstallSync

Async

• findPackageJson
• install
• uninstall
• latest
