|
|
> Convert object keys to camel case using [`camelcase`](https://github.com/sindresorhus/camelcase)
|
|
|
|
## Install
|
|
|
|
```
|
|
$ npm install camelcase-keys
|
|
```
|
|
|
|
## Usage
|
|
|
|
```js
|
|
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}}
|
|
|
|
camelcaseKeys({a_b: 1, a_c: {c_d: 1, c_e: {e_f: 1}}}, {deep: true, stopPaths: ['a_c.c_e']}),
|
|
//=> {aB: 1, aC: {cD: 1, cE: {e_f: 1}}}
|
|
|
|
// Convert object keys to pascal case
|
|
camelcaseKeys({'foo-bar': true, nested: {unicorn_rainbow: true}}, {deep: true, pascalCase: true});
|
|
//=> {FooBar: true, Nested: {UnicornRainbow: true}}
|
|
```
|
|
|
|
```js
|
|
const camelcaseKeys = require('camelcase-keys');
|
|
|
|
const argv = require('minimist')(process.argv.slice(2));
|
|
//=> {_: [], 'foo-bar': true}
|
|
|
|
camelcaseKeys(argv);
|
|
//=> {_: [], fooBar: true}
|
|
```

|
|
c_e: {

e_f: 1
|
|
}
|
|
}
|
|
}, {
|
|
deep: true,
