    npm test

    jfq

    JSONata on the command line.

    This was inspired by the excellent jq utility, and uses JSONata rather than the jq language.

    Installation

    npm install --global jfq
    

    Usage

    jfq [options] [<JSONata query>] [<files>]
    

    It is good practice to put the JSONata query in single quotes, so that the shell does not attempt to interpret it.

    The output will formatted as JSON, unless it's an array of simple objects (e.g. string, number) when the output is flattened to a series of lines, so that it can be piped to another program such as xargs.

    Options

    • -n, --ndjson output as newline-delimited JSON (each object on a single line)
    • -j, --json force output as JSON, when it would normally be flattened
    • -y, --yaml output as YAML
    • -a, --accept-yaml accept YAML input
    • -q, --query-file <path> read JSONata query from a file

    Examples

    • To read the version of JSONata from the file package.json:
    jfq 'dependencies.jsonata' package.json
    
    # ^1.5.0
    
    • To find out how many downloads of JSONata there have been each month in the past year:
    curl -s \
      https://api.npmjs.org/downloads/range/last-year/jsonata \
      | jfq 'downloads{$substring(day, 0, 7): $sum(downloads)}'
    
    # {
    #  "2017-02": 36216,
    #  "2017-03": 46460,
    #  "2017-04": 40336,
    #  ...
    # }
    

    Install

    npm i jfq
