jq.node - like jq but WAY MORE powerful (300+ helpers 🔥)
Full Description

jq.node - Become a shell hero, get super-power

jq.node is JavaScript and Lodash in your shell (along with the 300K+ npm modules). It's a powerful command-line JSON/string processor. It so easy it feels like cheating your inner-bearded-sysadmin.


I'm a huge fan of jq but it was so many times inconsistent and irritating. It sometimes felt like JavaScript but it was not.
jq.node is what jq should be in my opinion. First version was written in 25 lines of JavaScript code and was already way more powerful than jq, backed from day one by more than 300 helpers from Lodash FP.

Why jq.node? Why not jq?

  • jq.node does not try to implement its own expression language, it's pure JavaScript
  • no need to learn new operators or helpers, if you know lodash/fp, you know jq.node helpers
  • more powerful than jq will ever be jqn 'filter(has("email")) | groupBy(u =>"@")[1]) | csv'
  • through --require command option, jq.node leverages 300K+ npm modules. Hard to do more powerful than that!

Why jq? Why not jq.node?

  • performance matters more than feature set (in our current implementation jq is faster than jq.node, C vs JavaScript)
  • some features of jq are not currently implemented in jq.node
  • jq is a binary, jq.node is a NodeJS project (🌟 soon accessible through a docker image)

Install (NodeJS)

npm install jq.node -g

Shameless plug


# the 4 commands below do the same thing
cat users.json | jqn 'filter(has("email")) | groupBy(function(u){return"@")[1]}) | csv'
cat users.json | jqn 'filter(has("email")) | groupBy(u =>"@")[1]) | csv'
cat users.json | jqn 'filter(has("email")) | groupBy(u => get("@"), 1)) | csv'
cat users.json | jqn 'filter(has("email")) | groupBy(flow(get("email"), split("@"), get(1))) | csv'

Note: the pipe | must always be surrounded by space to be understood by jqn as a pipe.


Be notified when a JSON value Changelog

while true; do curl -s | jqn 'property("task.status"), thru(a => exit(a === "IN_PROGRESS" ? 0 : 1))' || osascript -e 'display notification "Task done"'; sleep 5; done

Open every links from the clipboard

pbpaste | jqn -x -r opn 'split("\n") | forEach(opn)'
  • pbpaste, echoes clipboard content, MacOS only (use xclip or xsel in Linux)
  • opn is "a better node-open. Opens stuff like websites, files, executables. Cross-platform."


-h, --help

Display the help message and exit.

-j, --json

Force the result to be output as JSON. Without this, jqn outputs strings verbatim and non-strings as JSON.

-x, --raw-input

Read input as a string.

-c, --color

Colorize JSON (--color=false to disable it)

-r, --require <npm-module-name>

Require a NPM module <npm-module-name>. jq.node will automatically installs in a temporary folder it if its not available. The module will be available in the expression through its name (e.g. lodash for the lodash module). Module names that are invalid JavaScript variable names (e.g. js-yaml) will be exposed in camel-case format (e.g. jsYaml).

-v, --version

Display the version and exit.
