base-tree - npm

Add a tree method to generate a hierarchical tree structure representing nested applications and child objects.

Install with npm:

var tree = require('base-tree');

Creates a .tree method on app that will recursively generate a tree of nodes specified by the names option passed in.

Params

• options {Object}: Options to use in .tree method
• options.names {String|Array}: Names of the collection objects to look for child nodes.
• options.method {String}: Optional method names defined on the app. Defaults to tree.
• options.tree {Function}: Optional tree function to use to generate the node or tree of nodes for the current app. Takes app and options as parameters.
• options.getLabel {Function}: Get a label for the node being built. Takes app and options as parameters.
• options.getMetadata {Function}: Get a metadata object for the node being built. Takes app and options as parameters.
• returns {Function}: plugin

Example

var app = new Base();
app.use(tree({names: 'children'}));

app.children = {};
app.children.one = new Base();
app.children.two = new Base();
app.children.three = new Base();

console.log(app.tree());
console.log(archy(app.tree()));

Default tree building function. Gets the label and metadata properties for the current app and recursively generates the child nodes and child trees if possible.

This method may be overriden by passing a .tree function on options.

Params

• app {Object}: Current application to build a node and tree from.
• options {Object}: Options used to control how the label and metadata properties are retreived.
• returns {Object}: Generated node containing label, metadata, and nodes properties for current segment of a tree.

Figure out a label to add for a node in the tree.

Params

• app {Object}: Current node/app being iterated over
• options {Object}: Pass getLabel on options to handle yourself.
• returns {String}: label to be shown

Additional metadata that should be added to a node

Params

• app {Object}: Current node/app being iterated over
• options {Object}: Pass getMetadata on options to handle yourself.
• returns {Object}: metadata object to add to node

Clone the repository, install dependencies and run the example with node.

$ git clone https://github.com/doowb/base-tree
$ cd base-tree
$ npm install
$ node example.js

The example will output the raw object and a formatted tree structure using archy
