## What it is
A single-file Node.js CLI tool called '' for parsing, validating, filtering, and pretty-printing JSON on the Unix command line. It supports lookups, in-place file editing, streaming newline-delimited JSON, and stripping HTTP headers from REST API responses.

## Use cases
- pretty-print  from curl output
- extract a field from a  response on the command line
- validate  config files from the shell
- filter and process newline-delimited  streams
- edit  files in place from a script
- strip http headers before parsing  payloads

## When to choose
- you want a zero-dependency, single-file  tool for shell pipelines
- you work with REST API responses including curl -i header blocks
- you need fast streaming processing of newline-delimited JSON objects

## When to avoid
- you need jq's full query language or advanced transformations
- you don't have Node.js installed and prefer a self-contained binary
- you need to process very large JSON documents with random access

## Facets
- artifact type: cli-tool
- maturity: stable
- function: cli, parser, developer-tools
- domain: developer-tools, apis
- platform: cli, cross-platform
- tags: -processing, pretty-printing, streaming, jq-alternative, rest-api-debugging, command-line, nodejs
