jq for JSON

I sufficiently old to recollect after we thought XML was going to vary the programming world…then JSON saved us from that hell. Parsing and querying JSON knowledge is prime activity we have all coded for, however typically I simply wish to get some knowledge domestically with minimal fuss. I simply discovered of a extremely superior library to take action: jq. Let’s take a look at some cool issues we are able to do with jq!

Begin by putting in jq through a utility like Homebrew:

brew set up jq

With Homebrew put in and a neighborhood actors.json file, let’s go to work on pulling some knowledge!

// Utilizing this JSON file:
// https://uncooked.githubusercontent.com/algolia/datasets/grasp/motion pictures/actors.json

// Get the tenth merchandise in an array
cat actors.json | jq '.[10]'
// {
//   "identify": "Dwayne Johnson",
//   "ranking": 1568,
//   "image_path": "/akweMz59qsSoPUJYe7QpjAc2rQp.jpg",
//   "alternative_name": "The Rock",
//   "objectID": "551486400"
// }

// Get a property from the tenth merchandise in array
// > "Dwayne Johnson"

// Get a number of gadgets
jq '.[10:12]'

// Get gadgets as much as the twelfth place
jq '.[:12]'

// Get gadgets after the twelfth place
jq '.[12:]'

// Get an array of properties from all objects
jq '.[].identify'
// > ["William Shatner", "Will Ferrell", ...]
