Package Exports

loopback-filters

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (loopback-filters) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

loopback-filters

This module implements LoopBack style filtering without any dependencies on LoopBack.

Install

Usage

Below is a basic example using the module

var applyFilter = require('loopback-filters');
var data = [{foo: 'bar'}, {bat: 'baz'}, {foo: 'bar'}];

console.log(filtered);

The output would be:
