Flattener

Object flattener helper library. Convert (nested) objects to and from flat objects of keypath values.

Documentation

flatten

flatten(source,[delimeter='.'])

Transform any deep nested object in a flat object of keypath values. You can specify a custom path delimiter (defaults to .)

Flattener.flatten({user: { name: 'peperone' }});
{'user.name': 'peperone'}

Custom delimiter:

Flattener.flatten({user: { name: 'peperone' }}, '/');
{'user/name': 'peperone'}

unflatten

unflatten(flatObject,[delimeter='.'])

Transform a flattened object into a regular object.

Flattener.flatten({'user.name': 'peperone'});
{user: { name: 'peperone' }}

Custom delimiter:

Flattener.flatten({'user/name': 'peperone'}, '/');
{user: { name: 'peperone' }}

glob

glob(flatObject,regexp)

Iterate over all keys and return the ones matching a given regexp.

Examples

The following is an example of flattening a user object:

let user = {
  name: { title: 'mr', first: 'brad', last: 'gibson' },
  location: {
    street: '9278 new road',
    city: 'kilcoole',
    state: 'waterford',
    postcode: '93027',
    coordinates: { latitude: '20.9267', longitude: '-7.9310' },
    timezone: { offset: '-3:30', description: 'Newfoundland' }
  },
  email: '[email protected]',
  handles: [
    { site: 'twitter', handle: 'mr.brad' },
    { site: 'github', handle: 'bradC0d3z' }
  ]
};

let flatUser = Flattener.flatten(user);
console.log(flatUser);

The output in the console would show something similar to the following:

{
  'name.title': 'mr',
  'name.first': 'brad',
  'name.last': 'gibson',
  'location.street': '9278 new road',
  'location.city': 'kilcoole',
  'location.state': 'waterford',
  'location.postcode': '93027',
  'location.coordinates.latitude': '20.9267',
  'location.coordinates.longitude': '-7.9310',
  'location.timezone.offset': '-3:30',
  'location.timezone.description': 'Newfoundland',
  email: '[email protected]',
  'handles.0.site': 'twitter',
  'handles.0.handle': 'mr.brad',
  'handles.1.site': 'github',
  'handles.1.handle': 'bradC0d3z'
}

You can go back to a regular object:

let obj = Flattener.unflatten(flatUser);

Getting Started

Download the production version or the development version.

Development

npm install && bower install

If you need to sudo the npm command, you can try to:

sudo chown $(whoami) ~/.npm
sudo chown $(whoami) /usr/local/share/npm/bin
sudo chown -R $(whoami) /usr/local/lib/node_modules

If you bump versions, remember to update:

• package.json
• bower.json
• component.json
• etc.

Bower

Bower is a package manager for the web. It offers a generic, unopinionated solution to the problem of front-end package management, while exposing the package dependency model via an API that can be consumed by a more opinionated build stack. There are no system wide dependencies, no dependencies are shared between different apps, and the dependency tree is flat.

To register flattener in the bower registry: bower register flattener git://github.com/goliatone/gflattener.git

Then, make sure to tag your module:

git tag -a v0.1.0 -m "Initial release."

And push it:

git push --tags

Travis

In order to enable Travis for this specific project, you need to do so on your Travi's profile. Look for the entry goliatone/flattener, activate, and sync.
