miniquery

miniquery

miniquery allows you to query objects for a given path and returns you an Array of values matching.

Installation

First install miniquery in you project:

npm install --save miniquery

Getting started

Then, use it:

var miniquery = require('miniquery');
var assert = require('assert');

var fruits = [{
  name: 'orange'
  count: 2,
  colors: ['orange']
}, {
	name: 'banana',
  count: 0,
  colors: ['yellow', 'white']
}, {
	name: 'kiwi',
  count: 8,
  colors: ['brown', 'green']
}];

var orangeColor = miniquery('0.colors.0', [fruits]);
assert.deepEqual(orangeColor, ['orange']);

var counts = miniquery('*.count', [fruits]);
assert.deepEqual(counts, [2, 0, 8]);

var colors = miniquery('colors.#', fruits);
assert.deepEqual(colors, ['orange', 'yellow', 'white', 'brown', 'green']);

Note that miniquery always returns an Array even if there is no or only one result.

## CLI usage

Install miniquery globally:

sudo npm install -g miniquery

Then, simply run your queries on one or more JSON files. Let's assume we want to list distinct keywords on all of our NodeJS projects :

miniquery "keywords.*" ~/projects/*/package.json -p | uniq
# minimatch
# gulp
# svg
# gulp
# gulp-plugin
# (...)
# github
# REST
# HTTP
# server
# web
#services

Get every available options by running:

miniquery -h

# Usage: miniquery [options] <query> <file ...>
#
# Options:
#
#   -h, --help       output usage information
#   -V, --version    output the version number
#   -v, --verbose    tell me everything!
#   -j, --json       output JSON
#   -p, --primitive  print primitives only

## API

### values:Array miniquery(path:String, objs:Array) Return the values matching the given path for the objects contained in objs.
