So far, you have used a email/password combination to authenticated with the application. Firebase offers more than this sign in method. If you take a closer look at their documentation, you can find social sign in methods for Google, Facebook, Twitter and others. In this section, I want to show you how to use these social logins to give users…
First off, this tutorial assumes that you have some knowledge of how React works. If you're just getting started to React, I'd highly recommend reading through The Road to learn React before trying to dive into ReasonReact. It's really important to have at least a basic foundational understanding of React. After all, ReasonReact is an abstraction…
Previously, we implemented authentication for this Firebase in React application. Along the way, we added authorization with roles. You may have experienced a flicker every time you reload/refresh your browser, because the application doesn't know from the start if a user is authenticated or not since the authenticated user is null. It will happen…
So far, you've used broad authorization rules that check user authentication, where the dedicated authorization higher-order component redirects them to the login page if the user is not authenticated. In this section, you will apply a more specific authorization mechanism. It works with roles (e.g. Admin, Author) assigned to a user, but also with…

Today, I am super excited to announce the release of The Road to GraphQL - Your journey to master pragmatic GraphQL in JavaScript with React.js and Node.js . Writing this book proved to be a challenge with GraphQL technologies changing often, but I managed to get an updated version published in time to keep you ahead of the curve. Perhaps the best…
Before we start to build full-fledged GraphQL applications, on the client- and server-side, let's explore GraphQL with the tools we have installed in the previous sections. You can either use GraphiQL or the GitHub's GraphQL Explorer. In the following, you will learn about GraphQL's fundamentals by executing your first GraphQL queries, mutations…
Apollo is an entire ecosystem built by developers as an infrastructure for GraphQL applications. You can use it on the client-side for a GraphQL client application, or server-side for a GraphQL server application. At the time of writing this tutorial, Apollo offers the richest and most popular ecosystem around GraphQL in JavaScript. There are other…
As I worked with my recent client to develop their lay out the groundwork for their React application, I found out that testing was an important topic for them. They are shipping their React application into embedded systems only once or twice a year. As conclusion there must be a guarantee that everything is working as expected, because there are…
Recently a client of mine inspired me to learn RxJS for State Management in React. When I did a code audit for their application, they wanted to get my opinion about how to proceed with it after only using React's local state . They reached a point where it wasn't feasible to only rely on React's state management . The initial discussion was…
