Convert object keys from camelCase to lowercase with a custom separator
The `decamelize-keys` npm package is designed to convert object keys from camelCase to lowercase with a customizable separator, making it useful for transforming JavaScript object keys to match different coding or data format conventions.
Convert object keys from camelCase to a custom separator
This feature allows you to convert the keys of an object from camelCase to another format using a custom separator, such as a hyphen. It's particularly useful for preparing data to be sent to APIs or systems that require a different naming convention.
const decamelizeKeys = require('decamelize-keys');
const result = decamelizeKeys({ 'fooBar': true, 'barBaz': 'yes' }, '-');
console.log(result); // Output: { 'foo-bar': true, 'bar-baz': 'yes' }Exclude specific keys from being decamelized
This functionality allows you to exclude certain keys from being transformed. It's useful when you have specific keys that need to remain in camelCase for consistency or compatibility reasons.
const decamelizeKeys = require('decamelize-keys');
const options = { exclude: ['fooBar'] };
const result = decamelizeKeys({ 'fooBar': true, 'barBaz': 'yes' }, '-', options);
console.log(result); // Output: { 'fooBar': true, 'bar-baz': 'yes' }Similar to `decamelize-keys`, `humps` can also convert keys between camelCase and snake_case. However, `humps` provides more comprehensive options for both decamelizing and camelizing keys, making it a versatile choice for different case conversion needs.
The `snakeize` package is focused on converting object keys to snake_case. While it serves a similar purpose to `decamelize-keys` in terms of changing the case of keys, it is specifically tailored for snake_case conversion without the flexibility of choosing a custom separator.
As the inverse of `decamelize-keys`, `camelcase-keys` converts object keys from snake_case or kebab-case to camelCase. It's useful for scenarios where you need to convert data to match JavaScript's naming conventions, offering a complementary functionality.

decamelize
This project was forked from camelcase-keys and converted to do the opposite
$ npm install --save decamelize-keys
const decamelizeKeys = require('decamelize-keys');
decamelizeKeys({fooBar: true}, '-');
//=> {'foo-bar': true}
