Package description
The camelcase-keys npm package is designed to convert object keys to camel case. It can be used to transform keys in objects, arrays of objects, and deeply nested objects. This is particularly useful when dealing with APIs that return data in snake_case or other formats and you want to convert the keys to camelCase to maintain JavaScript naming conventions.
Convert object keys to camel case
Converts the keys of a single object to camel case. For example, {'foo_bar': true} would become {'fooBar': true}.
{"foo_bar": true}Convert array of objects
Converts the keys of every object in an array to camel case. For example, [{'foo_bar': true}, {'bar_baz': false}] would become [{'fooBar': true}, {'barBaz': false}].
[{"foo_bar": true}, {"bar_baz": false}]Deep key conversion
Converts keys to camel case recursively for deeply nested objects. For example, {'foo_bar': {'inner_key': 'value', 'another_key': {'deep_key': 'deep_value'}}} would become {'fooBar': {'innerKey': 'value', 'anotherKey': {'deepKey': 'deepValue'}}}.
{"foo_bar": {"inner_key": "value", "another_key": {"deep_key": "deep_value"}}}Exclude keys from being camelCased
Allows certain keys to be excluded from being converted to camel case. For example, {'foo_bar': true, 'do_not_change': false} with 'do_not_change' as an excluded key would result in {'fooBar': true, 'do_not_change': false}.
{"foo_bar": true, "do_not_change": false}The humps package is similar to camelcase-keys and provides functions for converting between camelCase and snake_case. It also offers the ability to decamelize keys, which camelcase-keys does not.
As the name suggests, snakecase-keys is designed to convert object keys to snake_case. It is the opposite of camelcase-keys, which converts keys to camelCase.
This package offers a variety of case transformations for object keys, including camelCase, snake_case, and others. It provides more general case conversion functionality compared to camelcase-keys, which focuses specifically on camelCasing.
Readme
Convert object keys to camelCase using
camelcase
$ npm install --save camelcase-keys
const camelcaseKeys = require('camelcase-keys');
// Convert an object
camelcaseKeys({'foo-bar': true});
//=> {fooBar: true}
// Convert an array of objects
camelcaseKeys([{'foo-bar': true}, {'bar-foo': false}]);
//=> [{fooBar: true}, {barFoo: false}]
camelcaseKeys({'foo-bar': true, nested: {unicorn_rainbow: true}}, {deep: true});
//=> {fooBar: true, nested: {unicornRainbow: true}}
const camelcaseKeys = require('camelcase-keys');
const argv = require('minimist')(process.argv.slice(2));
//=> {_: [], 'foo-bar': true}
camelcaseKeys(argv);
//=> {_: [], fooBar: true}
