Installation:

yarn add lensify

or if you prefer npm:

npm install --save lensify

Development:

yarn install

npm run watch:js

run tests: npm test

How to use

import lensify from 'lensify';

const initialState = {
	playerMoves: 0,
	totalScore: 100,
	deeper: {
		deepProp: "foo",
	},
};

const stateL = lensify(initialState);

Now stateL is an object with the exact same structure as initial state, except all keys are now (ramda) lenses.

You can use them in a redux reducer, for example:

const scoring = (state = initialState, action) => {
	switch (action.type) {
		case actionTypes.UPDATE_PLAYER_MOVES:
			return R.over(stateL.playerMoves, R.add(action.moves), state);
		case actionTypes.UPDATE_TOTAL_SCORE:
			return R.over(stateL.totalScore, R.add(action.points), state);
		default:
			return state;
	}
};
