Learn Android, Reason and Sequelize

This course foremost will teach you about the syntax and semantics of the programming language Reason or also referred to as ReasonML. In addition, the course touches on best practices recommended by the official documentation. Each lesson is focusing on a specific feature, concept or best practice and can be watched independently. Still, the whole course is carefully crafted, and each lesson builds up on the previous ones.

Simple, fast & type safe code that leverages the JavaScript & OCaml ecosystems.

A lot of the time, web apps are built primarily with the desktop layout in consideration, and the mobile layout suffers as a result. In this course we are going to discuss using features of user interface which are optimised for mobile devices.

We are going to discuss CSS features that make a big difference and build entire components that work great on mobile devices and browsers. We are going to take into account browser support to ensure our users are getting the experience we want them to.

More and more of our users depend on their mobile device to use our web apps. With this in mind, we are going to look at how to optimise the components we build for smaller viewports, and how to ensure our customer gets an optimised version of our web app for their device.

We are going to discuss different ways we can view, test, and debug our web app in a mobile setting so that we know what we are seeing is what our user is seeing, because sometimes a desktop browser emulating a mobile device just isn’t enough.


HTML 5 is the structure of our web pages. It is the markup that represents the DOM (document object model).

Node.js is a well established server runtime that many companies are using worldwide. Express.js is a server framework for Node.js used by over 5 million projects. ReasonML is a type-safe functional language that compiles to Javascript.

This playlist collects the basic pieces of information a programmer needs to get started building servers in ReasonML on Node.js and Express.js. Follow along to learn how to get the speed of Node, combined with the added type-safety of Reason.

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

ReasonML Applications for the React Developer

Open source framework for building truly native mobile apps with Angular, TypeScript or JavaScript.

We will learn how to add an Android library to our project and translate it’s Java api to NativeScript. For this lesson, we will look at [Filestack’s Android SDK](https://github.com/filestack/filepicker-android) built with Gradle. Specifically, we will cover how to immediately start working with the library even when a [NativeScript](/q/nativescript) plugin does not exist for it.

Flutter allows you to build beautiful native apps on iOS and Android from a single codebase.

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.

Progressive Web Apps can speed up app loading times, and even allow you to run your web app offline, and install it on a mobile device!  However, setting up a PWA correctly can be tricky.

In this course, we'll create a PWA from start to finish, using create-react-app.  We'll create a custom service worker, and use different caching strategies for different types of assets.

Finally, we'll look at how to install the app on both iOS and Android devices, and how to customize the app name, icon, and splash screen.

In this lesson we’ll learn how to use themes in order to share colors and font styles throughout our application.

In this lesson we’ll learn how to render both local & network images in a Flutter application using the Image class.

In this lesson we’ll learn about the main layout widgets you'll need when building your user interface in Flutter. We’ll take a look at Container, Center, Row, Column, Stack, & GridView widgets learn how they work.

Building Layouts in Flutter with Layout Widgets

In this lesson we’ll learn how Navigation in Flutter works by navigating to a new page when clicking on a button using the push & pop methods. We'll also look at how to pass properties to a new screen dynamically.

Getting Started with Navigation in Flutter

In this lesson, we'll learn how to specify a configuration object containing all of the routes for our application & navigate between them in a Flutter application.

ListView is the most commonly used scrolling widget in a Flutter application. In this video, we'll learn how to create dynamic lists using Flutter's ListView widget to render both lists of Strings & lists of Maps

In this lesson we’ll learn how to fetch & then display data from an API over the network in a Flutter application using the http package.

Throughout the last year, the use of React hooks has taken the world of web development. Hooks provide users with an easy way to handle interactivity within ReactJS applications, so it's no surprise that the latest release of the ReasonReact library makes great use of them. 

In this lesson, we'll get started using ReasonReact `0.7.x` by scaffolding out an application using the [BuckleScript](https://bucklescript.github.io/) command-line tool. Once scaffolded, we'll go through the steps needed in order to properly run our application within a development environment that is ripe for productivity!

Up and Running with React Hooks inside of a ReasonML 

Any React developer will agree that 2019 was the year of that hooks took the library by storm. Luckily for us, the ReasonRect library makes it possible to hooks within the context of a ReasonML application.

In this lesson we will take a test drive of the `useReducer` hook within a ReasonML application. By the end, we'll have learned how to define our actions using variants, use records to shape our state, and more!

When working with traditional React, we often pass functional stateless components the `props` object as an argument. Although there are a few minor differences when working in the context of Reason, the act of passing `props` to a component is done in an extremely similar manner.

In this lesson, we will get a first-hand look at just how similar these processes are by walking through the steps of creating a React Component in ReasonReact. By the end, you'll have developed an understanding of ReasonReact's "named args" syntax which it uses for creating components and you'll have created a re-usable Layout component that can be used to share layout throughout an application.

One of the key benefits of BuckleScript is the ease in which it makes the process of porting JavaScript libraries so they can be used within the context of a ReasonML application. The Reason Package Index, or [redex](https://redex.github.io/), provides a central place for browsing all available packages. Additionally, creating your own BuckleScript bindings is a straight forward process that also provides value in the form of knowledge surrounding the inner-workings of the library at hand.

In this lesson, we learn how to integrate the emotion css-in-js libray into our project by installing the `bs-css` package. Once installed, we'll create a `.re` file for our style rules and see how we can add global css, as well as styles for specific css classes which we'll target using React's `className` prop.

ReasonML is a fantastic way to write Javascript! But it doesn't yet have a built-in async / await syntax. Furthermore the built-in libraries for working with Javascript promises are awkward to work with, and produce code that's hard to read. This lesson will teach the viewer how to use the "bs-let" language extension (called a PPX) to achieve readable, easy to write promise-based code.

Async / Await in ReasonML

Although ReasonML has built-in libraries for working with JSON, they are low-level and difficult to use by hand. The Decco library offers automatically generated JSON decoders, and produce a result that keeps the programmer safe at runtime by telling them whether the data they got matched the shape of the data they expected. 

Automatically decode JSON into records in ReasonML using Decco

This lesson shows how the Serbet server library for ReasonML and Node.js makes handling JSON request bodies, and responding with JSON request bodies a simple task.
