Everything and anything to do with technology in today’s world.
Roughly three years ago I started writing a series of posts on the wp.data API. Little did I know how valuable this post would be to so many people within the WordPress community (and at my current employer Automattic)! Of course, as it is with all APIs, changes happen and while the content of the […]
At various places so far in this series, you would have seen me use phrases like: I’ve also mentioned that I’d get to this mysterious “registry” reference later in the series. Well, here we are! What problem does the Registry solve? As a part of diving into what the registry is in the context of […]
Now we have a resolver for asynchronously getting products via a REST api endpoint, we have some action creators, and we have a selector. We haven’t got to the reducer yet, but before we get to it, let’s consider another problem we haven’t addressed yet. When we update or create a product using our ui, […]
The WordPress data module (or package) is a critical component of the new WordPress Editor as demonstrated by it’s implementation in (at the time of writing) 7 other WordPress packages: @wordpress/block-directory registers a store with the core/block-directory namespace. @wordpress/block-editor registers a store with the core/block-editor namespace. @wordpress/blocks registers a store with the core/blocks namespace. @wordpress/core-data […]
The primary way in which you interact with state in wp.data is through a registered store. In this post we’re going to give an overview of the api for registering a store and then subsequent posts will dive into the specific components of the store config. registerStore( reducerKey, options ) Every data store found in […]
In the last post I gave you a quick overview of the api for registering a new data store. I mentioned that this next post would take a closer look at the individual properties of a store, but before we do that, let’s take a brief break and take a look at an app that […]
In the previous post of this series, we took a brief interlude to take a look at an app that is using tree state to manage the data the app is using. We discovered that, while the app was functional, some potential problems with using state this way were beginning to surface. In this post, […]
Before we took our side detour into learning about the controls property, I mentioned that since we now have a selector for getting products, it’d be good to implement a way to retrieve the products from the server. This is where resolvers come in. Let’s get started by creating a resolver for retrieving products. If […]
In the exploration through wp.data, we’ve already created the necessary properties needed to register the custom products store for our example app. This includes, action creators, selectors, controls, and resolvers. Now it’s time to get to the last property we need for registering our store, and that’s the reducer. The reducer is arguably the most […]
To recap: so far in the series we’ve looked at the various properties of the configuration object for a store: selectors: which interface with the store for retrieving data from its state. actions: (actually action creators) which are used to dispatch action objects for handling by the reducer. reducer: which receives dispatched actions and determines […]
