tshirt

How to use

var tshirt = require('tshirt');
var data = [
        {a:1},
        {a:'one',b:4,c:{},d:[]},
        {a:{},b:42},
        {a:[]}
    ]
var shape = tshirt(data);
console.log(shape);
/*
{ 
    a: Set { 'number', 'string', 'object', 'array' },
    b: Set { 'number', 'optional' },
    c: Set { 'object', 'optional' },
    d: Set { 'array', 'optional' } 
}
*/

Use case inspiration

It sucks opening a 500mb list of objects and manually enumerate the data types for each property. Tshirt solves this by determining the shape of your documents.

Improvements

Support nested properties.
