Selector for JSON contents

[roniemartinez]

There are existing ways to extract data from JSON without traversing the contents one by one.

Options

• JsonPath
• JMESPath

Proposed style

@select(jsonpath="$.store.book[0].title")
def extract_title(title):
    return {"title": title}


@select(jmespath="locations[?state == 'WA'].name | sort(@)")
def extract_washington_cities(cities):
    return {"cities": cities}

Notes

• Only applies if content type is application/json
