javascript - Making Node.js work with tree-model-js -

thanks tree-model-js, great lib! new node.js , i'm trying import tree-model. npmed successfully. trying make node.js work library. guess node question , not tree-model issue, asking anyway in case lib needs changed it.

i have following:

var tm = require('tree-model'); //all far. 

but when trying recreate code works on webpage

//is how access it? tm.tree = new treemodel(); 

it giving me error. have examples on how can achieved in node?

essentially trying within main.js node file struggling understand how access variables/functions. works when on webpage when following:

tree = new treemodel();  root = tree.parse({ name: "ben , jerry" }); 

any examples appreciated. please keep in mind new node.js , somehow rookie on javascript. learn better examples feel free point me in right direction.

the error quite simple: treemodel not defined.

require('tree-model') returns new node(this.config, model) , in code, node assigned variable tm. should use new tm() instantiate node or change variable name treemodel
