Install

Install with npm:

$ npm install --save filter-object

Usage

Filter with glob patterns

var filter = require('filter-object');

console.log(filter({a: 'a', b: 'b', c: 'c'}, '*'));
//=> {a: 'a', b: 'b', c: 'c'}

console.log(filter({a: 'a', b: 'b', c: 'c'}, 'b'));
//=> {b: 'b'}

console.log(filter({foo: 'a', bar: 'b', baz: 'c'}, 'b*'));
//=> {bar: 'b', baz: 'c'}

console.log(filter({a: 'a', b: 'b', c: 'c'}, '{b,c}'));
//=> {b: 'b', c: 'c'}

console.log(filter({a: 'a', b: 'b', c: 'c'}, ['a', 'b']));
//=> {a: 'a', b: 'b'}

Negation patterns

console.log(filter({foo: 'a', bar: 'b', baz: 'c'}, ['!b*']));
//=> { foo: 'a' }

console.log(filter({a: {b: {foo: 'a', bar: 'b', baz: 'c'}}}, ['!a.b.b*']));
//=> {a: {b: {foo: 'a'}}}
