Learn Nuxt, Redux-observable and Webstorm

Handling async actions that affect your application’s state sounds like a tall order, but Redux makes it possible — and a win-win for you and your app’s users.

In this course, we will begin with nothing more than an empty directory and a text editor. Through small, focused lessons, we’ll learn how to set up a React project that uses Redux for state management and redux-observable for asynchronous actions. We’ll see how ‘epics’ are registered and how they each receive a ‘stream’ of actions from the store.

With an understanding of how things work, we’ll move onto solving common problems like: 
- Ajax cancellation
- creating sequences of async actions
- enabling code reuse through higher-order Observables 
- and much more.

RxJS 5-based middleware for Redux. Compose and cancel async actions to create side effects and more.

Up and Running with redux-observable

This course walks you through the steps of creating a News web app using Vue.js and the Nuxt framework. You will learn how to create dynamic pages for each section of your application and load, store, display, filter, and style the data. Then end result will be a News app with multiple category pages, comments for each section, and user pages.

Vue (pronounced /vjuː/, like view) is a progressive framework for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only, and is very easy to pick up and integrate with other libraries or existing projects. On the other hand, Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.

In this video you'll learn how to deploy a static Nuxt site to AWS's global edge CDN in less than two minutes. We'll start from scratch, creating a new Nuxt site using npx and walk through the build configuration to set up the deployment target for Jamstack / static site hosting. From there, we'll initialize a new Amplify project using the Amplify CLI and walk through the settings to configure the proper build command for Amplify hosting. Finally, we'll deploy and view the live site. Once we're finished, we'll delete the project and the hosting service.

Deploying a Nuxt Site to AWS with the Amplify CLI

In this video you'll learn how to use Amplify hosting to deploy a Nuxt site from a Git repository. We'll begin by walking through the steps of creating the deployment and configuring the correct build settings to enable a static build. Once the site is deployed, we'll view the live site hosted on AWS.

In this lesson we’ll learn exactly what’s needed to incorporate redux-observable into an existing React/Redux application. We’ll learn what ‘Epics’ are, and how they receive a stream of actions and return a stream of actions. In-between is where we get to apply side-effects, call out to external services etc etc. In this lesson we’ll demonstrate the ‘async’ nature of epics by responding to an action with another, delay action.

Add redux-observable to an existing Redux project

Redux is a predictable state container for JavaScript apps.
It helps you write applications that behave consistently, run in different environments (client, server, and native), and are easy to test.

In this lesson we’ll learn how to perform an Ajax request to an external API in response to an action in the redux store. We’ll see how, within the epic, we get access to actions after any reducers have been executed and how we can convert that incoming action into a resulting one that will save the data received into the redux store.

Use redux-observable for simple Ajax requests

With redux-observable, we have the power of RxJS at our disposal - this means tasks that would otherwise be complicated and imperative, become simple and declarative. In this lesson we’ll respond to an action by queuing up 2 separate Ajax requests that will execute sequentially. Then we’ll group the results from both into an array and produce a single action from our epic that will save the data into the redux store

Create a queue of Ajax requests with redux-observable and group the results.

When accepting user input and converting it into a request that talks to the outside world, we can often end up in a situation where responses are no longer relevant. This is a common case in type-ahead style input fields - we would only want to call an external search API after the user has stopped typing for a short amount of time. In this lesson we’ll see how we can begin to combine RxJS operators to solve such problems. 

Debounce user input to avoid repeated Ajax requests

Any application that uses external services such as APIs should be able to handle errors gracefully. Often this requires no more that displaying a message to the user and ensuring the application continues to function. In this lesson we’ll look at how we can convert an error from the network into an action that is dispatched into the Redux store, allowing us to show an error message to the user and prevent the application from crashing.

Handle network errors gracefully

Although ‘epics’ in RxJS are often described as ‘actions in, actions out’, there may be times when you need to ‘bail out’ of an action, or to just ignore the current one given some condition. By learning about RxJS’s `filter` Operator, we’ll see how easy it is to do ‘nothing’ when you need to. We’ll also see how the composition techniques available in RXJS allow us to control the UI in a declarative manner.

Filter a stream to exclude empty values

In certain situations, you care more about the final state of the redux store than you do about the particular stream of events coming out of an epic. In this lesson we explore a technique for dispatching actions direction into the store, having the epic execute as they would normally in production, and then assert on the updated store’s state.

Use tests to verify updates to the Redux store

When exploring a new framework or technology, it is nice to have a seed project or sandbox so you can just get in and start playing. Let's build our React playground using npm, browserify, 6to5, and more within WebStorm!

Setting up a React Playground Dev Environment

Before each page loads, Nuxt supports pre-fetching data to render what you need on the server. This lesson walks you through using Nuxt's `fetch` to load data then save it in the Vuex store.

Load Data from APIs with Nuxt and Vuex

The Vue-CLI helps you to quickly and easily setup new Vue projects. Nuxt.js is a library that helps you build server-rendered Vue.js applications. This lesson shows you how to use the nuxt/starter template with the Vue-CLI to quickly start a new project.

Most applications require state to be shared across the application. In the case of Nuxt, you'll share state across pages. Nuxt integrates easily with Vuex by simply adding JavaScript files in the `store` directory. This lesson walks you through setting up a basic store and using it in your template

Manage Vue.js State with Vuex and Nuxt

You commit changes to state in Vuex using defined `mutations`. You can easily access these state mutations in your template using `mapMutations`. This lesson shows you have to wire together your Vue.js template with your Vuex store using mutations and mapMutations.

Update Vuex State with Mutations and MapMutations in Vue.js

You'll notice soon after working with Nuxt that you'll begin to see your styles flash in during each page load. This is due to the development mode of Nuxt where it injects the styles into the page after the initial page render. You can rest assured that when you use `nuxt build`, your styles will render before the page loads.

Understand the Flash of Unstyled Content in Nuxt

Because Nuxt renders pages on the server, you should use the `nuxt-link` components to navigate between pages. Each time a page loads, you can check if you're on the client or server and avoid doing unnecessary loading based on how the page was rendered. This lesson walks you through using `nuxt-link` and `isClient` to navigate and avoid reloading data.

Navigate with nuxt-link and Customize isClient Behavior in Nuxt and Vue.js

You can isolate parts of templates you want to re-use into components, but you can also reuse those components across pages using layouts. This lesson walks you through creation a navigation component then extracting it out into the default layout.

Build a Navigation Component in Vue.js and Use in a Nuxt Layout

You can easily add CSS libraries to Nuxt using `yarn` or `npm` to install them, then simply adding them to the `nuxt.config.js` so they're included in each page. Then all the classes will be available for use in all of your templates. This lesson walks your through installing a library then adding it to your `nuxt.config.js`.
