nave

Virtual Environments for Node

Installation

If you want a global nave command, you could install this thing with npm. But that's not really necessary. You can run the nave.sh shell script from here, or symlink it wherever you want.

Usage

nave install 0.1.92             # install version 0.1.92 of node
nave test 0.1.92                # run the tests on node version 0.1.92
nave use 0.1.92                 # enter a subshell where 0.1.92 is being used
nave use 0.1.92 my-program.js   # run my-program.js with node 0.1.92
nave ls                         # show the versions fetched/installed
nave clean 0.1.92               # delete the source code for 0.1.92
nave uninstall 0.1.92           # delete the install for 0.1.92

That's about it. Enjoy.

env vars

Check the $NAVE variable to see which version is being used. $NAVELVL tells you how many layers in you are. (A lot of nave use commands can create a nested situation. Not really sure what this would be useful for, though.)

When you're done using a specific version of node, just exit the shell to return to where you were before using nave.

Credits

nave borrows concepts, inspiration, and code from Tim Caswell's "nvm" and Kris Kowal's "sea" programs.

Sea is really nice, but is very tied to Narwhal. Also, it's a require.paths manager, which nave is not.

Nvm is also really nice, but has to be sourced rather than being run, and thus is a little bit wonky for some use cases. But it doesn't involve subshells, which makes it better for many others.
