I have really enjoyed its convention over configuration approach. In the JS world this is incredibly refreshing to see and a huge time saver while developing. With that leaves a bit of a gap in documentation and real-world usage from being so new. One of the tenants of functional programming is writing small functions that do one thing really well.

We often go astray from this with tight deadlines, or a lot of pressure to fix a hot issue quickly. But at some point that comes back to haunt us, and creates an opportunity to revisit designs that no longer fill their purpose.

Maybe more than once in our careers we find a variable being mutated as a side effect of another event or function call as the source of a bug? Vuex provides a one-way highway for handling application states.

To clear this up more, lets look at the architecture:. Vuex is everything inside the dotted green box. When a component is rendering, it has access to Vuex state and in turn can be used for whatever that component needs to function. Once rendered, it can dispatch or mutate the store, therefore causing anything else using that store to update.

Honestly the official documentation is very confusing about which way one should approach configuring Vuex. It is my opinion if you have more that three API calls or state management items to handle the modular approach is required. Outside of quickly getting something working at the beginning of a Nuxt project the single-store approach becomes just as painful as using global variables.

Knowing that modules are the best way to go, the documentation suggests building an index. Unless you plan on configuring Vuex with some fancy plugins or changing its configuration, index. State is a simple function that returns the object stored inside it. That is all fine if it is read-only. How annoying right? But that actually makes a lot of sense if you look at that picture above again.

If you could change state directly, then you skip the parts that will let the rest of your app know it has changed. To get around using a deeply dot-notation path you want to use the mapState helper. Deeply nested objects in a state lose reactivity.Want to learn Vue. Universal or Isomorphic JavaScript is a term that has become very common in the JavaScript community. Many modern JavaScript frameworks, like Vue. This is done to improve the user experience and make the app seem faster, since users can see updates to pages instantaneously.

Server-side rendering of JavaScript is about preloading JavaScript applications on a web server and sending rendered HTML as the response to a browser request for a page. Building server-side rendered JavaScript apps can be a bit tedious, as a lot of configuration needs to be done before you even start coding. This is the problem Nuxt. Simply put, Nuxt.

It abstracts most of the complex configuration involved in managing things like asynchronous data, middleware, and routing. According to the Nuxt. Another great feature of Nuxt. In addition to Vue.

We can do this by running the following command:. This will be basically be the file that are telling Nuxt to use contentful as a plugin, which enables us to easily fetch our data from Contentful. This file will need to hold some configuration. We need to require the newly created config file and add a bit of code to our nuxt. The env property is a way to define values that will be available when using process.

Before we can fetch content into the application, we need to create a content type and some content. Start off by navigating to the tab: Content Model and set up a new content type. Once the content type is created, we need to add some fields to it. Go ahead and create some pages based on the content type created. Our website needs a navigation so our users can navigate between pages.

First thing we need to do is import the client from the Contentful plugin we created earlier in the plugins directory. Next, we need to make use of the asyncData method. This allows us to fetch and render the data server-side. Interested in learning more about asyncData?

All it does is redirect the page if there's no auth data in the store. For a summary, the initAuth function will make auth available in the state without much configuration. Since Nuxt is running both client- and server side, it has limits on the availability of certain browser specific variables like window.

Because of that, trying to configure the feathers client to use window. There's a simple solution though:. When you configure the auth module in your feathers-client, use cookie-storage instead of window.

We only have to pass the api's that we need to hydarate on client start to the nuxtClientInit. If you have issues with sub-dependencies not loading correctly, you may want to check out this GitHub issue. One of the suggestions is likely to fix the issue.

Sometimes you just want to fetch data and pre-render it on the server without using a store. It will be called server-side once on the first request to the Nuxt app and client-side when navigating to further routes.

This method receives the context as the first argument, you can use it to fetch some data and Nuxt. You do NOT have access of the component instance through this inside asyncData because it is called before initiating the component. Choose the one you're the most familiar with:.
