    Usage

    Hide some fields from an object

    const project = require('mongo-project');
     
    const object = {
      title: 'Bar title',
      author: {
        name: 'Foo Person',
        email: 'foo.person@example.com',
      },
    };
     
    const projectedObject = project(object, {
      'author.email': 0,
    });
     
    console.dir(projectedObject);
    // {
    //   title: 'Bar title',
    //   author: {
    //     name: 'Foo Person'
    //   }
    // }

    Only show specific fields of an object

    const project = require('mongo-project');
     
    const object = {
      title: 'Bar title',
      author: {
        name: 'Foo Person',
        email: 'foo.person@example.com',
      },
    };
     
    const projectedObject = project(object, {
      'title': 1,
      'author.name': 1,
    });
     
    console.dir(projectedObject);
    // {
    //   title: 'Bar title',
    //   author: {
    //     name: 'Foo Person'
    //   }
    // }

    More complex examples can be found in the tests.
