Boilerplate and helper functions for redux that can be shared amongst FounderLab apps
createGroupByReducer
Use this to take an action parsed by responseParser and generate a map of lists of model ids grouped by a given key
e.g. here the byLesson property of the state will be a list of file ids that share a lessonId
const byLesson = createGroupByReducer([TYPES.FILE_LOAD + '_SUCCESS'], file => file.lessonId)
...
/*
state will look like:
{
...
byLesson: {
123: {
id: 1,
lessonId: 123
},
456: {
id: 2,
lessonId: 456
},
},
}
*/
