trymodule 
A simple cli tool for trying out different nodejs modules.
Installation
npm install -g trymodule
Usage
trymodule colors
Downloads the module colors if needed, and starts a nodejs REPL with colors loaded in the current scope, ready for you to use.
trymodule colors lodash
Same as above but with many packages in one go!
trymodule colors=c lodash=l
Assign packages to custom variable names.
trymodule --clear
Removes the directory where trymodules stores the node modules. Removes TRYMODULE_PATH + '/node_modules'
Configuration
There are a couple of environment variables you can use to customize trymodule.
TRYMODULE_PATH for setting the path of where modules are stored. By default this is $HOME/.trymodule or $USERPROFILE/.trymodule
TRYMODULE_NONINTERACTIVE for making trymodule not fire up the repl in the end. This is useful if you want to just install some packages for future use. By default this is undefined. Setting it to any value would make trymodule non-interactive.
TRYMODULE_HISTORY_PATH for changing where to save the repl history. Should be pointing to a user write-able file. Defaults to $TRYMODULE_PATH/repl_history
You can set the environment variables for one session with export TRYMODULE_PATH=/usr/bin/trymodule or for just one time by doing TRYMOUDLE_PATH=/usr/bin/trymodule trymodule colors.

Inspiration
Inspiration comes from a leiningen plugin called lein-try that allows you to try out clojure libraries without having to declare them in an existing project. Thanks to @rkneufeld for the inspiration!
