Learn Algolia, Leaflet and Vue

If you've ever worked on a website for a business, there's a good chance you've included a map.

A Google Map embed is sufficient for showing a location, but doesn't leave you many customization options.

React Leaflet to the rescue!

In this course, Colby Fayock will guide you through a series of lessons and challenges that will build your map making skills as you build out a web app for a fictional restaurant.

You'll get practice with handling API keys and using React Hooks to implement a custom interactive map complete with metadata and additional overlays.

This course has built-in challenges that you are encouraged to pause and work through, but feel free to just watch.

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

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.

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.

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

Today’s users expect great things from their search experiences — speed, relevance, and usability, to name a few. Algolia provides developers with out-of-the-box and customizable search experiences that are a joy to build.

This introductory course on the Algolia search solution focuses on the user-facing part of search. Using the Algolia InstantSearch.js front-end library, we’ll see how to build an engaging search experience in no time. (28 minutes, to be exact.) 

**Prerequisites:** 
You don’t need previous experience with search to follow this course — we’ll use an example index with an e-commerce data set preconfigured. We will work mainly in JavaScript, so basic JS knowledge is expected.

If you want to play with your own index settings and data set, you can [create a free Algolia account here](https://www.algolia.com/users/sign_up/hacker/?utm_medium=link&utm_source=egghead&utm_campaign=education), but this is not required to follow along with this first course. 

Algolia's full suite APIs enable teams to develop unique search and discovery experiences for their customers across all platforms and devices. Type a query. Click a link. Open an app. Everything your customers do sends a signal about what they want. Algolia decodes that intent to deliver the right content - instantly.

Getting Started with Algolia InstantSearch.js

***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.

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

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

HTML has a few elements with semantic meaning. While they can be a bit subjective as to when you should use them, you should avoid using them as names for your Vue components.

The stats widget is used to display useful insights about the current results like the number of hits and the time taken to compute the results inside the engine.

Inform users about the current result set with Instantsearch JS Stats widget

The first step to implement Algolia on the front end using Instantsearch : importing and setting up the library with your credentials. This is what will allow the library to initiate the connection to Algolia servers and the first step to complete before adding some useful widgets.

Set up the Instantsearch JS Library

In this lesson we’ll build a search experience reduced to it’s 2 essential components : a search input and the displayed results. As simple as it is, to build this from scratch would require a fair amount of work. Between listening to the input, making the api call, parsing and displaying the result... To build this using Algolia’s Instantsearch library requires a few lines of code with simply two widgets: the Searchbox and the Hits widget.

Search an Algolia Index with Instantsearch JS searchbox and hits widgets

Displaying barebones Hits won’t catch your user’s attention. The UI is key to provide a good search experience and hits are the meat of this experience so they need extra attention. By using Mustache templating we’ll see how to display rich results to your users. 

Display Rich results with templates in the Hits widget for Instantsearch JS

Every  good search UX make users understand instantly why a given hit is being displayed as part of the result set. One way to achieve that is to highlight the keywords from the query directly inside the Hits. This is built in the API JSON response and in this video we’ll explain how to leverage it easily.

Highlight Keywords in Query Results using the Instantsearch JS Hits Widget

Searching is obviously not limited to inputting text in a searchbox. If your dataset allows it Algolia can leverage of attributes and values. To make use of those facets on the front end, one of the most common widget that you can find in a search UI is the refinement list. With this widget, the user can filter the dataset based on facets. This widget only displays the most relevant facets for the current search context.
