Filter

Allow to keep only the defined container’s keys.

filter(paths)

Filter the container’s body to keep only the keys listed on the paths argument array.

Argument	Type	Description
paths	string or [string]	Required. Paths or path to filter on the body.

If the container’s body currently contains those data:

{
  "username": "shudrum",
  "birthdate": "1982-12-28",
  "firstname": "Julien",
  "lastname": "Martin"
}

You can filter values simply by calling the filter worker:

const workflow = [
  filter(['firstname', 'lastname']),
];

The resulting container’s body will be:

{
  "firstname": "Julien",
  "lastname": "Martin"
}
