snake-to-camel-converter

A simple npm package for converting object keys from snake_case to camelCase.

Installation

npm install snake-to-camel-converter

Usage

const snakeToCamelConverter = require('snake-to-camel-converter');

// String Case Conversions
const inputString = "this_is_a_test_string";

const camelCaseString = snakeToCamelConverter.convertToCamelCase(inputString);
console.log(camelCaseString);

const snakeCaseString = snakeToCamelConverter.convertToSnakeCase(camelCaseString);
console.log(snakeCaseString);

const pascalCaseString = snakeToCamelConverter.convertToPascalCase(snakeCaseString);
console.log(pascalCaseString);

const kebabCaseString = snakeToCamelConverter.convertToKebabCase(pascalCaseString);
console.log(kebabCaseString);

// Object Key Conversions
const inputObject = {
  first_name: 'John',
  last_name: 'Doe',
  contact_info: {
    email_address: '[email protected]',
    phone_number: '123-456-7890'
  }
};

const camelCaseObject = snakeToCamelConverter.convertToCamelCase(inputObject);
console.log(camelCaseObject);

const snakeCaseObject = snakeToCamelConverter.convertToSnakeCase(camelCaseObject);
console.log(snakeCaseObject);

const pascalCaseObject = snakeToCamelConverter.convertToPascalCase(snakeCaseObject);
console.log(pascalCaseObject);

const kebabCaseObject = snakeToCamelConverter.convertToKebabCase(pascalCaseObject);
console.log(kebabCaseObject);

Example

Input

const inputObject = {
  my_key: 'value',
  nested_object: {
    another_key: 'another_value'
  }
};

Output

{
  myKey: 'value',
  nestedObject: {
    anotherKey: 'another_value'
  }
}

Input with array

const inputObject = {
  my_key: 'value',
  nested_object: {
    another_key: 'another_value'
  },
  my_array: [
    {
      my_key: 'value',
      nested_object: {
        another_key: 'another_value'
      }
    },
    {
      my_key: 'value',
      nested_object: {
        another_key: 'another_value'
      }
    }
  ]
};

Output with array

 {
  myKey: 'value',
  nestedObject: {
    anotherKey: 'another_value'
  },
  myArray: [
    {
      myKey: 'value',
      nestedObject: {
        anotherKey: 'another_value'
      }
    },
    {
      myKey: 'value',
      nestedObject: {
        anotherKey: 'another_value'
      }
    }
  ]
};

Example with JSON

{
  "first_name": "John",
  "last_name": "Doe",
  "contact_info": {
