Enables chained lodash functions with ES bind (::) syntax
npm install lodash-bound> Enables chained lodash functions with ES bind (::) syntax
  
babel-plugin-lodash and lodash-webpack-plugin introduced an optimizaion that includes only the used lodash methods in the compiled webpack file. So you can still import _ from 'lodash' without having the entire lodash library to load.
However, chaining is not supported. _.chain(value).method() or _(value).method() will result in an (understandable) error.
That error links to this article which suggests using lodash/fp in order to maintain somwhat chained syntax.
With the new ES bind syntax, ::, it's now possible to 'chain' a method to an object, as if it was on its prototype.
``js`
function upcase() { return this.toUpperCase() }
function shout(n) { return this + '!'.repeat(n) }
console.log('hello'::upcase()::shout(5)) // => HELLO!!!!!
This library wraps all lodash methods with functions that consider this as the value, because lodash methods take a value as a first argument, which wouldn't fit the :: syntax.
Each method requires only the single corresponding file from lodash, so no unnecessary sources are being added to the output.
`sh`
npm install lodash-bound --save
Requires also babel-preset-es2015 and babel-preset-stage-0 babel presets.
`js
import _map from 'lodash-bound/map'
import _filter from 'lodash-bound/filter'
import _groupBy from 'lodash-bound/groupBy'
import _mapValues from 'lodash-bound/mapValues'
let arr = [
{ id: 'm1', conversationId: 'c1', body: 'hello', read: true },
{ id: 'm2', conversationId: 'c1', body: 'world', read: false },
{ id: 'm3', conversationId: 'c2', body: 'foo', read: false },
{ id: 'm4', conversationId: 'c2', body: 'bar', read: false }
]
let unreadBodyByConversationId = arr
::_filter({ read: false })
::_groupBy('conversationId')
::_mapValues(x => x::_map('body'))
> Note: Webpack 2 will support 'tree-shaking' which eliminates unused requires. This will allow requiring all methods in one statements:
, without requiring all the rest of the methods.Test
