Helpers for using ramda with immutable.js

Currently only provides lenses using the lens function.

Installing#

npm install --save ramda-immutable

Make sure you install ramda and immutable too cause they are peer dependencies.

Helpers#

lensProp and lensIndex#

import { set } from 'ramda';
import { lensProp } from 'ramda-immutable';
import { fromJS } from 'immutable';

const feelingLens = lensProp('feeling');
const afterSet = set(
	feelingLens,
	'awesome',
	fromJS({ id: 1, feeling: 'sad' })
); // => { id: 1, feeling: 'yay!' }

the only difference between lensIndex and lensProp is the key type.

lensPath#

creating a path of lenses.

import { set } from 'ramda';
import { lensPath } from 'ramda-immutable';
import { fromJS } from 'immutable';

const afterSet = set(
	lensPath([0, 'sad']),
	'awesome',
	fromJS([{ id: 1, feeling: 'sad' }, { id: 2, feeling: 'good' }]),
);
