# jpath
# jsonpath-cli
Command Line node application to query JSON using jsonpath
## Motivation
jq is an awsome json query utility however jsonpath has (IMHO) a much simpler query language and easier to learn. I did not find a command line implementation to directly use JSON path queries.
### Reference:
https://www.npmjs.com/package/jsonpath#jsonpath-syntax
jq is an awsome json query utility however jsonpath has (IMHO) a much simpler query language and easier to learn. I did not find a command line implementation to directly use JSON path queries.
## How to install
1. Clone the repo
2. install globally
```
npm install -g jsonpath-cli
```
## How to execute
```
npm install -g .
cat <input.json> | jpath <jsonpath query>
```
Note: on Windows, the generated jpath.cmd file was incorrect. if you face batch file error, replace the jpath.cmd file with the file in project folder.
### Jsonpath query quick Reference:
3. Execute using following command
```
cat input.json | jpath <jsonpath query>
```
