homefront

Build Status

Merge, flatten, expand, search in, fetch from, remove from, put in and work with objects easily.

Image unrelated

Makes working with javascript objects really easy, in both the browser and on the server.

Installation

npm i --save homefront

Tests

npm test

Usage

Usage is pretty straight forward.

Homefront class

Working with homefront

let Homefront = require('homefront').Homefront;
let homefront = new Homefront(data, Homefront.MODE_NESTED);

// Put a value.
homefront.put('me', 'down');

// Fetch a value.
homefront.fetch('me', 'default value');

// Remove a value.
homefront.remove('me');

// Use dot-notation for nested objects.
homefront.put('user.profile.username', 'Frank');
homefront.fetch('user.profile.username');
homefront.fetchOrPut('user.profile.username', 'Francis');
homefront.remove('user.profile.username');

// Merge new data into your object
homefront.merge({override: 'something'}, {and: {add: {something: 'else'}}});

// And the same again, but with nested keys!
homefront.merge(
  {'no.way.this.is.not.possible': 'right?', 'you.are.wrong': 'It is'},
  {mind: 'blown'},
  new Homefront({andThis: 'also works'})
);

// And, sorry, the same again, but static.
Homefront.merge({foo: 'bar'}, {bat: 'baz'});

// And sort of the same, apply defaults.
homefront.defaults('you.are', {
  wrong : 'never set, because it already exists',
  right : 'applied because non-existent',
  nested: {also: 'works'}
});

// Flatten object (nested objects to dot-notation keys):
homefront.flatten();

// Expand object (dot-notation keys to nested objects):
homefront.expand();

// Helpers
homefront.isModeFlat();
homefront.isModeNested();
homefront.getMode();
homefront.setMode(Homefront.MODE_FLAT);

// Constants
Homefront.MODE_FLAT;
Homefront.MODE_NESTED;

Expand

let expand   = require('homefront').expand;
let data     = {'my.nested.key': 'value', 'my.nested.other': 'value'};
let expanded = expand(data); // => {my: {nested: {key: 'value', other: 'value'}}}

Flatten

Returns a flattened object, with all nested keys dot separated.

let flatten   = require('homefront').flatten;
let data      = {foo:{bar:{bat:'baz'}}};
let flattened = flatten(data); // => {'foo.bar.bat': 'baz'}

Building the code

For this code to work in the browser, there's an extra transpile step included. Running this is as easy as executing the following command:

npm run build

The built code will appear in the dist directory.

Breaking changes

Since the last major version bump, method .defaults() has been renamed to .applyDefaults() as defaults cause exceptions on some browser. It shadows the name of a strict-mode function.
