treeize

treeize

v0.0.3

Converts row data (in JSON/associative array format) to object/tree structure based on column naming conventions.

Installation

npm install --save treeize

Usage

Treeize currently has a single function, grow, that takes your results/rows of flat associative data and returns a full object graph;

• The column/attribute order is not important. All attributes are sorted by depth before mapping.
• To imply a collection, use a plural name (e.g. "subjects" instead of "subject"). Otherwise, use a singular name.
• Use a + to seperate path nodes (e.g. "toys+name" implies a "toys" collection on a root level item. Each toy item would have [at least] a "name" attribute)

var treeize = require('treeize');

var flatData = [
  {
    "name":             "Mittens",
    "age":              12,
    "toys+name":        "mouse",
    "toys+owner+name":  "Mittens"
  },
  {
    "name":             "Mittens",
    "age":              12,
    "toys+name":        "yarn",
    "toys+owner+name":  "Ms. Threadz"
  },
  {
    "name":             "Tiger",
    "age":              7,
    "toys+name":        "a stick",
    "toys+owner+name":  "Mother Nature"
  }
];

var converted = treeize.grow(flatData);

Output

  {
    "name": "Mittens",
