Lazy Require
Lazy require allows you to require modules lazily, meaning that when you lazy require a module that is missing, lazy require will automatically install it for you.
Usage
// Importvar lazyRequire = // Attempt to load the module `ambi`, if it doesn't exist, then try to install it and load it again// Do this synchronously, only available in Node 0.12 and above// Passing a callback as the 3rd argument will do this asynchronously, available in all node versionsvar ambi = if ambi instanceof Error // Error .... console else // Success ... // Attempt to load the module `ambi`, if it doesn't exist, then try to install it and load it again// Do this synchronously but with a callback, only available in Node 0.12 and abovelazyRequire // Attempt to load the module `ambi`, if it doesn't exist, then try to install it and load it again// Do this asynchronously, available in all node versionslazyRequire // Attempt to load the module `ambi`, if it doesn't exist, then try to install it and load it again// Do this synchronously if supported (Node 0.12 and above), otherwise do it asynchronouslylazyRequire
The following options are supported:
