#recursive-lowercase-json
This module provides a function that accepts one argument, a JSON-compatible JavaScript object. It returns a deep copy of that object with all object keys transformed to lowercase-only (including objects nested inside of arrays).
Any object will work, but if it contains JSON-incompatible properties (e.g. functions), they will be ignored (or interpreted as empty objects). The module's intended use is for JSON responses from APIs, which may contain object keys with a capitalized format -- perhaps not in line with your application's conventions.
##Installation (get it from npm):
npm install recursive-lowercase-json
Usage:
/**
* ES6/ES2015 syntax
*/
import recursivelyLowercaseJSONKeys from 'recursive-lowercase-json';
const data = {
Data1: {
FieldA: 1,
FieldB: false
},
Data2: [
{
FieldC: "hello"
}
]
};
const lowercaseData = recursivelyLowercaseJSONKeys(data);
console.log(lowercaseData);
/**
* prints:
* { data1: { fielda: 1, fieldb: false },
* data2: [ { fieldc: 'hello' } ] }
*
