npm install --global jfq
Usage
jfq [options] [] []
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
.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 read JSONata query from a fileExamples
- To read the version of JSONata from the file package.json:
`
jfq 'dependencies.jsonata' package.json^1.5.0
