Learn Algolia, React-native and Tachyons

How to create buttons in React Native depending on the level of desired customisability: the quick and simple Button, a more customisable Touchable, and the most customisable Pressable.

Button component is useful for quick prototyping.

TouchableOpacity is the most common way of creating buttons and other touchable areas, and is suitable for most use cases.

Pressable gives you the most control over the look and feel of your button, including customising the pressed state and text, as well as handling long presses separately from regular presses.

React Native lets you build mobile apps using only JavaScript. It uses the same design as React, letting you compose a rich mobile UI from declarative components.

Creating Buttons in React Native with Three Levels of Customization

If you already know React, then React Native is a great way to build mobile apps for iOS and Android. Of course, web and mobile apps are very different to build — but this course serves as your guide.

In this course, we’ll build a mobile app from start to release with React Native for both iOS and Android. Prior React experience is required, but you don’t have to know anything about mobile development to participate.

Throughout the course, we’ll be building a “Restaurant Review” app. We’ll use all the standard mobile UI elements like text, images, form inputs, buttons, scroll views, and icons, and we’ll show several navigation techniques like push, modal, and tabs. The app will make HTTP API calls to a server and will store data on the device with AsyncStorage. Finally, we’ll specify a custom app icon and splash screen, deploy the app to a physical device, and prepare the app for release to the App Store and Play Store or for ad-hoc release.

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

React makes it intuitive to build real-world web application. But in reality, you need to use a host of other services to get the app in front of real users. 

This course walks you through setup and implementation to get your cloud-based application up and running. 

You’ll learn to set up:
* a new project in AWS Amplify configured to your React app
* user authentication with Amazon Cognito 
* managed GraphQL with AWS AppSync
* image storage and retrieval with Amazon S3
* text translation via Lambda functions
* and finally, deployment of your application on AWS using Amazon S3

You’ll finish the course ready to quickly and easily deploy your serverless React application, so users can start using and enjoying it right away.

React Navigation makes the easy things easy and the hard things possible. This course will help you understand how to customize and use React Navigation for more complex navigation patterns.

You'll learn different ways to display content within the navigators, which demonstrates the built-in customizations within React Navigation. As well as learn how to interact with different UI components within React navigation, which will help you structure your application. 

Building off this, you'll learn how you can customize the default navigator behavior to provide a custom look and feel to your React Navigation application

To succeed in this course, you’ll want a basic understanding of the React Navigation API and how to use the default navigators.

Note: React Navigation has been updated to v2. This course was recorded on v1.x and the lesson code has been updated to reflect v2. The principles and patterns taught in the videos remain valid.

React Navigation for Native Mobile Applications

React Native Video is a community supported video element for React Native. It allows for remote loading of videos and also works with the React Native asset management system to load videos. Having a flexible video component is essential to developing and enhancing your application.
Like many React Native elements, the video element is very basic and doesn't ship with anything besides a flexible API. This allows you to develop the exact layout, controls, and custom overlays to match your application.

In this course we'll take a look at a basic setup. Then explore the different ways we can load and show videos. We'll show how to use a few of the custom callbacks to overlay errors and buffering elements. Because there are no controls shipped with `react-native-video` we'll show how to write custom video controls and animate them when the video has not been interacted with.

Finally we'll cover a few common paradigms found in the wild. Including repeating background cover videos, auto-playing videos when they scroll onto the screen and auto-stopping them when they are scrolled away from.

Fundamentals of React Native Video

In this course we'll explore how to create many popular animated concepts in applications across web and mobile applications. We'll look at both simple, complex, and subtle interactions that you can use to enhance your React Native application.


This course should empower you to look at an animation in an application, break down the effect, and rebuild it in your own application.


The ultimate goal is to show how using the basic Animated calls we can build out effective and complex animations that take your application to the next level.

Real World React Native Animations

In this course we will learn and demonstrate the basic concepts of the React Native Animated API. We'll use Animated calls like `timing` and `spring` to animate style properties, and learn how to combine animations to create more complex effects. We'll learn about more advanced interactions like animations with touch events, interpolation, and flip animations. The ultimate goal is to gain an understanding of how to animate React Native Views, how you can apply them to many different types of styles, and how to enhance the experience in your application.

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.

Animate React Native UI Elements

In this course we’ll explore getting started with a basic React Native application on both iOS and Android. We’ll learn about using React Native components, how to build custom components, how to layout an application using Flexbox, and how to style components.


We’ll also focus on how to use state to control components, how to persist information across application reloads with AsyncStorage, and how to inline edit in a ListView.

The ultimate goal is to gain an understanding of how to get started building simple React Native applications.

Build a React Native Todo Application

If you're a web developer who has been itching to get into native development, now is your chance. In this series we'll be talking all about React Native. React Native allows you to build native iOS and Android applications in JavaScript and React.js. 

Regardless of your experience with React, or even with iOS development, my hope is that this series will be beneficial to everyone who is starting out with React Native. We'll jump straight into developing with React Native by looking first at the ecosystem of building React Native apps - including  Xcode, the iPhone simulator, live reload, debugging, and more. 

Once we get our ecosystem set up and our hello world example running using ES5, we'll jump straight into building a fully functioning iPhone app which utilizes many of the best parts of developing with React Native all while covering React.js and refactor to ES6 along the way.

React Native Fundamentals

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.

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.

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.
