Learn Dart, Postgres 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

You've got some practice with using SQL to select, update, and join database tables.

But perhaps you've found yourself with a sneaking suspicion that you could be more efficient with your PostgreSQL.

Does your query seem slow?

A lesson on how to profile queries will point you in the direction of a fix.

Are you performing multi-step operations one at a time that are susceptible to errors?

The "all or nothing" transaction is the cure.

These are just a couple of examples of the techniques, tips, and tricks that Tyler Clark has learned in his years of experience working on large scale production applications.

Other topics in this course include working with CSV files, different techniques for aggregating & filtering, and more!

Watch Tyler's course, and continue your journey toward SQL mastery.

Advanced SQL for Professional Developers

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

Most applications rely on databases to store data. Understanding how to create a database and communicate with it unlocks a critical power in your web development career. 

In this course, Tyler presents all the building blocks of creating and interacting with a PostgreSQL database. From creating a brand new table, up through organizing and aggregating data across multiple tables, you will learn the fundamental skills of SQL — and you’ll be prepared to apply them right away.

After completing this course, you’ll be ready to tackle more challenging SQL topics like proper data modeling, normalizing data, and exploring different database types.

***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.

Build Async Vue.js Apps with RxJS

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.

Offline-First Progressive Web Apps (PWA) in Vue.js

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.

Vue.js State Management with Vuex and TypeScript

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.

You know the basics of Postgres, but most meaningful queries will require you to combine tables in novel ways to ask questions you couldn't ask with a single table alone. Joins and unions come up over and over again in interview questions -- because of how fundamental they are. This course will make you a master of your tables, and give you the power to answer questions you couldn't before. 

Understand Joins and Unions in Postgres

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.

Build a Server Rendered Vue.js App with Nuxt and Vuex

In this course we will show you how to wield the power behind the elusive window function. Which five movies were the highest grossing each year? Who are the highest performers in each department relative to their peers? These questions ask us to partition records into subgroups and answer questions about those groups -- that’s the power of a window function. 

Many programmers will reach for their favorite scripting language to solve problems like these, but window functions allow you to answer them with the speed and efficiency of the Postgres query planner.

Plus, with the power to further slice and dice this derivative information, there’s no limit to the questions you can answer with raw SQL.

If you’re interested in the Postgres client that is used in this course you can [download it here](https://macpostgresclient.com/?source=brett) to check it out and follow along.

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

When you are first building your blog site, it can be difficult to choose what content management system you want to use, and choosing a new framework can be daunting. They can be overwhelming and have a large learning curve.

Open up your knowledge of a powerful Nuxt module with Nuxt Content! Nuxt has a low barrier of entry and you don't have to fight with a content management system or API keys. 

In this course, you will learn how to create your own blog with just Nuxt and a folder of markdown files. Ben will take you from creating your Nuxt project from scratch all the way to deploying your digital garden on Netlify. 

Ben Hong is one of the core team members over at Vue.js and has developed this course to give you a concrete understanding of Nuxt Content and how to build your blog efficiently.

**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)

Create a GraphQL Powered Vue 3 Application

Supabase is an open-source tool for rapidly building application backends with real-time data and authentication. In this course, you'll learn the fundamentals of Supabase. You'll learn how to model complex data using PostgreSQL and SQL, build authentication flows with Oauth, and add real-time data to a Next.js application to build a fully-featured chat application, similar to Discord.

The chat app will have different "channels," which will be powered by data inside of Supabase. Users can visit these channels and write messages, which will be sent in real-time to other current users of the platform.

After this course, you will be able to model real-world scenarios in actual relational databases, understand how to manage real-time data, and leverage key functionality provided by Supabase, such as authentication, instant APIs, and real-time subscriptions.

Supabase is an open source Firebase alternative. A service to:

- Listen to database changes.
- Query your tables, including filtering, pagination, and deeply nested relationships (like GraphQL).
- Create, update, and delete rows.
- Manage your users and their permissions.
- Interact with your database using a simple UI.

Supabase is not a 1-to-1 mapping of Firebase. Most notably, Supabase uses Postgres rather than a NoSQL store.
