Styles and Standards

Actions

We stick to the Flux Standard Action spec. This states that an action must take the following shape:

{
    type: 'CONST',
    meta: {
        // Everything in 'meta' will *only* handled by middleware
    },
    payload: {
        // Payload contains all data for use within a reducer
    },
    error: '' // An optional error parameter
}

By sticking to this format we separate middleware logic from reducer payloads.

Selectors

Name selectors with a get prefix. For example, if your selector gets an array of blog post titles, it might be named getPostTitles.

Why? If we name it postTitles we'll have an import like import { postTitles } from './selectors'; at the top of our code, and nothing else will be able to be called postTitles within that entire file. Essentially we'll have to rename our props from postTitles to something else.

Giving a prefix to all selectors means:

1. We don't pollute component namespaces with the above issue
2. It's easy to tell when something's a selector via the get prefix
3. It's easy to search and replace these names within your project
