bo-selecta v1.0.0

bo-selecta

Wanted to put some 😍😍😍 into my mapStateToProps and came up with this.

const mapStateToProps = (state, {userId}} => {
  user: select('users').from(state).byId(userId),
};

It should integrate okay with your existing selectors if you've been structuring your Redux work in a reasonably standard way, like writing your selectors in the same file as the reducers whose state they read from.

Documentation

createSelect

const { createSelect } = require('bo-selecta');
exports.select = createSelect({
  users: {
    byId: (state, id) {
      return state[id];
    }
  }
});

stateAccessor

It assumes you're doing a very typical redux setup where the store is a plain JS object and each selector only reads from its reducer's section of the overall state. If the above don't apply, e.g. maybe you use Immutable.js, you can pass a custom stateAccessor to get the correct state param to your selectors.

const { createSelect } = require('bo-selecta');
const { * as userSelectors } = require('./reducers/users');
exports.select = createSelect({ users: userSelectors }, {
  stateAccessor(s, entity) {
    // Use the Immutable.js Map API to pass the correct subproperty of the store
    // to the selector functions
    return s.get(entity);
  }
});
