Does not work as a node.js module

[pmaxhogan]

Download this repo, cd there, and run node. Type this in:

var shoco = require("./shoco.js");shoco.decompress(shoco.compress("Hello, World!"));

I get this error:

TypeError: shoco.compress is not a function

instead of the expected "Hello, World!". FYI, var shoco = require("./shoco.js");Object.keys(shoco); returns:

BTW, var shoco = require("./shoco.js");shoco._shoco_decompress(shoco._shoco_compress("hi")); returns 0.
