Learn Apollo, Openapi and Vue

  Vue is a progressive framework for building UIs that allows you to incrementally integrate the technology into any existing project that you're working on. This makes it a great tool for you to learn as you can bring it anywhere.

This course is for learners just starting out in web development as well as for those who want to get up to speed on Vue 3 as fast as possible. You'll learn all the foundational skills of web development and how they are presented in Vue. 

We will start with an HTML, CSS, and JavaScript file as to not distract you with any possible tooling that goes on top of the building websites with Vue. 

You will incrementally build an app that sells comedy event tickets. In the end, you'll see how to deploy the application with Netlify Drag and Drop.

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.

The Beginner's Guide to Vue 3

Ever built a website? Did it have more than one page?

If it did, you learned quickly how essential routing is to the success of your project. And in so many frameworks routing is a painful and complex thing to learn.

But not in Vue!

Vue has an incredibly clean and powerful library called vue-router that takes care of everything you could need.

In this course, we'll cover what you need to know to get started with vue-router.

A Journey with Vue-Router

Modern applications know how to keep users informed of realtime updates through notifications, popups, and other messages.

On the development side, the ability to not only create web apps but have them communicate in realtime is a quirky, standout skill for your resume. It’s interesting, useful, and powerful.

In this course, Mark Barton will show you how to use Socket.io to facilitate bi-directional client-server communication and notifications using Vue on the frontend. Socket.io is a JS library that connects a client-side library to a node.js server. In the course, you’ll see how to use Socket.io to broadcast simultaneously to all or targeted clients based on filters you set up — so the right people see the right message at the right time.

You’ll learn to set up and connect Socket.io with node.js and Vue, and you’ll get practice making informed, complex architectural decisions around realtime broadcast messaging.

Vue and Socket.io for Real-Time Communication

GraphQL is a fan favorite for good reason. It lets a client make specific, complex, and/or aggregate queries for data, and it’s user-friendly to boot.

If you’ve been meaning to learn GraphQL and start harnessing its powers, this is a great place to start.

This course is for GraphQL newbies with a basic understanding of React. It focuses on the client-side implementation of GraphQL usage using the Apollo client.

We’ll start with a guide on how to add the Apollo client to an existing project, then move on using the Query and Mutation components to fetch and manipulate data using a GraphQL API.

React is one of the web’s most popular frameworks for building JavaScript applications. 

If you know what you’re doing, React can drastically simplify how you build, use, and maintain code.

Whether you’re a React newbie or you’re ready for advanced techniques, you can level-up with egghead. Explore our in-depth courses, lessons, and community resources to build more powerful applications and crack open your career.

***Note: RxJS imports have changed since the publication of this course, these changes to RxJS have been reflected in the code examples underneath each lesson. The concepts being taught on RxJS are still applicable.***

Vue.js is an amazing framework that can easily update and reflect user input using templates and data-binding. But there are many scenarios where complex asynchronous behaviors (like loading data, handling "pending" states, timeouts, etc) are solved much easier by leveraging the streaming capabilities of RxJS. This course covers how to setup and use the features of "vue-rx" to enable streams within your templates and easily solve complex scenarios.

Progressive Web Apps are just Web pages, but with superpowers.  They load under uncertain network conditions, even offline. They’re fast and engaging, providing the best user experience. They can be installed on your smartphone if the browser supports it, feeling like a native app.

In this course I’m gonna show you how to take an existing Single Page App made in Vue.js and pragmatically convert it to a Progressive Web App by creating a web manifest, then it goes through caching static assets, external resources and streams using service workers, applying code-splitting and lazy loading, notifying new versions of the app or wether is online or offline, understanding the preload and precache directives, finishing up by showing how to audit a Progressive Web App.

Vue is known for being super easy to pick up and quickly build great applications using the built-in template bindings and directives. As your application grows in complexity, you'll need finer control of your components.

In this course, we’ll define where content of a component should land when you define the content inside of a parent component with Vue slots and manage that relationship with slot-scope. We’ll continue with dynamic and async Vue components as well as use JSX inside Vue for complete JavaScript control of your components. 

This course provides an overview of Advanced Vue.js Components with quick demonstrations on how to leverage Vue Component patterns.

Advanced Fine-Grained Control of Vue.js Components

In [Use TypeScript to Develop Vue.js Web Applications](https://egghead.io/courses/use-typescript-to-develop-vue-js-web-applications) we’ve seen how TypeScript Vue apps development by creating class based components and using decorators.

This course will extend it, showing you how you can use Vuex with TypeScript in order to manage the state of your Vue app. We’ll see how to type-safe your store, organize the state in modules, modify it using mutations and actions and write Vuex plugins, all by creating a beer shop app throughout the course.

TypeScript is a powerful JavaScript superset which brings you first-class static type-checking along with latest ECMA Script features. Vue is one of the most modern libraries for managing the view layer.

Angular has fully adopted TypeScript as its language, and React has broad support for it. But, what about Vue?

This course will show how to take full advantage of TypeScript static typing on Vue apps by using class based components, typing directives and using decorators.

Use TypeScript to Develop Vue.js Web Applications

Vue.js has a first-class ecosystem to help construct Vue.js apps. This includes Nuxt.js which enables server-rendered applications and a page-based approach. 

This course will start with an empty app and walk through how to use Vue.js for building the app, Nuxt.js for organizing the app, and Vuex for managing state.

In this course, we will build a ToDo API that stores notes using the OpenAPI Specification (Swagger). We will start with a blank API definition using the Swagger Online Editor. The Swagger definition file will be used to create a Node.js API. Along the way, we will discover how to implement additional details required for a fully functional API requests and responses. We will also learn about the powerful capabilities of Swagger to generate server side code and client libraries.

Open API Initiative (OAI) is focused on creating, evolving and promoting a vendor neutral API Description Format based on the Swagger Specification

Vue is a "progressive framework for building user interfaces." Its core library is designed to be fast and flexible and is only focused on the view layer.

In this course, you'll gain a basic understanding on how to construct components and nested components and see how Vue reactively keeps the DOM up to date when data is changed. You should get a taste of what Vue has to offer and gain a better understanding of how you can use it for your own application development.

Develop Basic Web Apps with Vue.js

Most developers would raise an eyebrow if they saw database queries being done in a for-loop, but GraphQL provides just enough abstraction that it isn't always intuitive exactly how many times each resolver fires at scale, nor is it obvious how to batch operations efficiently and still return the correct results to the correct consumer.

You'll learn how to use the GraphQL Data Loader pattern to improve the performance of your application, and solve scaling issues before they become a problem.

To do this, we'll first implement our own naive version of the pattern to understand why the API is shaped how it is. Then we will switch over to the official DataLoader package and explore the benefits further.

## Skills you'll Gain

- Implement a cache layer to optimize your requests
- Batch requests so your Database isn't overloaded
- Build a performant GraphQL API

Apollo provides a universal GraphQL API on top of your existing services, so you can build new application features fast without waiting on backend changes.

Use GraphQL Data Loaders to Prevent Scaling Issues by Batching & Caching Database Requests

At the core of a good client-side GraphQL library is a cache. The cache is very important for improving the efficiency of your data retrieval and providing your users with a clean user experience.

In this course, we're going to see how Apollo's powerful cache helps easily solve complex UI problems, such as pagination, handling loading and error states, optimistic updates, and minimizing network requests.

We'll start from the basics, and look at how to make queries and mutations, but then we'll look at how the cache is behind most of Apollo's immediate benefits. We'll explore in-depth how it works, how it stores data, and how we can manually modify it manually for advanced scenarios.

Even if your backend doesn't fully support GraphQL yet, we'll look at how to write GraphQL queries in your components that retrieve local client state under the hood - or that can even make REST API calls.

**Get started building dynamic apps with GraphQL and Vue3.**

As your app scales, so does the complexity of managing your routes and API endpoints. 

It gets tiresome. 

But this aspect of web development can be streamlined considerably! 

GraphQL is a powerful tool for querying and mutating your data. In this course, we are going to create a Vue3 app that leverages GraphQL to create a dynamic front end.

But what does GraphQL *do*? 

Its power comes from giving you a *single* endpoint that you make all your queries to. Instead of making a request to a specific endpoint and getting a fixed response, you can write flexible queries to a single endpoint.

![REST vs GraphQL diagram](https://res.cloudinary.com/dg3gyk0gu/image/upload/v1638989029/course-resources/create-a-graphql-powered-vue-3-application/rest_vs_graphql.png)

Vue3 has some great new features that we will be exploring, such as the setup script syntax. But you won't just be exploring Vue3's new features, we will be building a dynamic front end with an index, view pages generated from data, and forms.

To make our frontend dynamic, we will be powering it with GraphQL. We start with the basics by creating queries but we move on to more advanced topics such as query params, mutations, and pagination.

To actually use GraphQL in our Vue app we will be using the Vue Apollo Client. Which gives us convenient methods for making queries, getting the data back into the client, and handling errors.

## Gain These Skills

- Add GraphQL to a Vue 3 project
- Query and mutate data with GraphQL in Vue 3
- Create data-driven views with Apollo client
- Handle routing within a Vue 3 project
- Implement optimistic updates and infinite scroll

## Prerequisites

Some entry-level knowledge on Vue and GraphQL is recommended, but this course is beginner-friendly enough to where it isn't a strict requirement.

If you want to build a deeper foundation for both Vue and GraphQL we have a couple of awesome courses that you can hack through. 

For Vue, check out **[The Beginner's Guide to Vue 3](https://egghead.io/courses/the-beginner-s-guide-to-vue-3-1c46da8b),** which is also by Kevin. It's great for both newcomers to web dev and veterans alike. 

And for GraphQL, work through **[GraphQL Query Language](https://egghead.io/courses/graphql-query-language)** from Eve Porcello. Eve literally wrote the book on learning GraphQL and her course is similarly top quality. 

## What's Next?

Progressive Web Apps are a more advanced topic, and converting an existing Single Page **Vue** App into one makes for an excellent follow-up project. **->** [Offline-First Progressive Web Apps (PWA) in Vue.js](https://egghead.io/courses/offline-first-progressive-web-apps-pwa-in-vue-js)

If you want to take your **GraphQL** game to the next level, then becoming an expert in designing GraphQL schemas is the way to go. **->** [Designing GraphQL Schemas](https://egghead.io/courses/designing-graphql-schemas-99db)

And I know the following recommendation is a React course but *it really is that good*. You will learn some **advanced** techniques that will be applicable to Vue or any other Apollo compatible framework that you work with. **->** [Manage State in React Apps with Apollo Client and GraphQL](https://egghead.io/courses/manage-state-in-react-apps-with-apollo-client-and-graphql-a45b3b89)
