$renameKeys

Renames keys of an object where they stand, so the order of the keys is kept. A key that is not there is passed over.

The source

{
  endpoint: {
    url: '/api/todos',
    body: { done: false },
    transform: 'rows',
  },
}

The config

{
  $renameKeys: {
    from: { $ref: '$.endpoint' },
    map: {
      body: 'request',
      transform: 'response',
      headers: 'meta',
    },
  },
}

What comes out

{
  url: '/api/todos',
  request: { done: false },
  response: 'rows',
}
