Learn A11y, Algolia and Angularjs

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.

- Web audio APIs include support for features that aren't available by default in the native HTML audio element.
- The operating system includes basic controls
- Custom controls must be accessible with a keyboard, and make sense to a screen reader
- Don't hide the built-in controls until you know that your custom controls are working
- Listening to what VoiceOver reads should inform the a11y information you include
    - VoiceOver says "Elapsed Time" on its own, so we wouldn't want to write it in our code.
- `loadedmetadata` should have the duration to avoid glitches from new audio not being loaded.
- Elements should be labeled with a unique `id`

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.

One of the hardest things about writing non-trivial applications is managing state. In our attempt to effectively manage state, we introduce additional complexity by trying to control application flow and the amount of code volume that comes from all of this. Redux gives us the ability to address state management and communication in astonishingly simple semantics that can be explained in just a couple minutes. The beauty of Redux is that it is not only a library but a pattern that works very will within Angular 1.x applications. In this series, we are going to learn how to integrate redux (the pattern) into Eggly from scratch and then introduce **ng-redux** and add in **Redux DevTools** at the end for fun.

AngularJS is an open-source JavaScript framework, maintained by Google, that assists with running single-page applications. Its goal is to augment web-based applications with model–view–controller (MVC) capability, in an effort to make both development and testing easier.

Web accessibility (also referred to as a11y) is the design and creation of websites that can be used by everyone. Accessibility support is necessary to allow assistive technology to interpret web pages.

React fully supports building accessible websites, often by using standard HTML techniques.

Erin Doyle is an expert in creating accessible React applications and has developed a course that will give you a concrete process for auditing react apps for accessibility. In this course, you will go through different tools and libraries to audit components in a React app.

Fast, easy and reliable testing for anything that runs in a browser.

Implementing modern component-based architecture in your new or existing Angular 1.x web application is a breath of fresh air.

In this course, you are going to take a close look at Eggly, an Angular 1.x application for organizing bookmarks, and build it using modern patterns and practices, inspired by Angular 2's recommended architecture.

You will learn how to leverage ES6 in your Angular 1 applications through Babel, and fully understand the core patterns that are used in a composed modular web application. 

This course will teach you how to leverage your existing knowledge of Angular, while preparing your mind (and applications!) for the future.

If you are interested, there is a [companion guide](http://www.angular2patterns.com/) that digs deeper into the patterns found in this course and Angular 2.

How much work would it take for you to move all of your directives and their templates to several different new directories? You'd have to update the templateUrl, script tags, etc., etc. With webpack, this can be trivial. For example, you don't need to worry about loading your templates in the $templateCache ever again. Webpack will help you modularize your css and tests. All of these things and more in this series so you can start using webpack with Angular today.

Introduction to AngularJS Material

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.

Filter Datasets with Facets using Instantsearch JS to add a Refinement List

The hierarchical menu widget is used to create a navigation based on a hierarchy of facet attributes. We generally implement it for categories with subcategories.

Browse results based on a hierarchy of Facets (HierarchicalMenu) in Instantsearch JS

The range input is a simple but useful widget that allows a user filter the results by selecting a numeric range with a minimum and maximum input. In an e-commerce website for instance, this widget would be useful to limit the results where the price is comprised between $X and $Y.

Refine a dataset using a numeric range in Instantsearch JS with the Range Input widget

When performing a complex query, based on several active facets and filters, its tedious for the user to start from scratch if she has to unset all refinements one by one. Thanks to the clearAll widget, this task becomes a one click action for the user and is trivial to implement for us developers as it requires no configuration.

Reset all active refinements with the clearRefinements Instantsearch JS widget

When you have a large result set for a specific query and usually not displaying more than a few dozen simultaneously. Pagination is a popular widget that allows the user to switch between pages of the results.

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

All Instantsearch widgets are added to the page in a similar fashion and they also share a number of common options that we’ll cover in this video. We will be playing with a dummy menu widget that won’t be part of the final project just to showcase all those options.

angular-formly provides a very simple API to dynamically change properties of your field (like disabled, hidden, and required) using the powerful expressionProperties property on your field.

angular-formly: expressionProperties

angular-formly allows you to default the values of fields for your angular forms using the `defaultValue` property. To default the value of a field, you can either initialize the `model` with the default value, or use this `defaultValue` property on the field configuration.

angular-formly: Default Values

AngularJS validation can be tough, but angular-formly makes it extremely simple with a single validation API that enables basic and advanced field validation. You can specify a string expression, function that returns true/false, or a function that returns a promise which is resolved/rejected.
