Possible solution to Redux action type name confilcts.

actions.js

//Action type constants don't have to have the same name as their value.
//Really, the const string value doesn't even have to be related to the action itself.
const UPDATE = 'randomValueGeneratedSomehow';

let updateThing = function(newValue) {
    return {
        type: UPDATE,
        payload: newValue,
    }
}

module.exports = {
    UPDATE,
    updateThing,
}

reducer.js

//The reducer doesn't care about the action type string value, only that the constant matches.
//So this constant name can be used by other reducers in other files without conflicting with this one.
let { UPDATE } = require('./actions.js');

function thingReducer(state = {}, action) {
    if(action.type === UPDATE) {
        return action.payload;
    }
    return state;
}
