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
