React Course for Beginners by Professionals
App Building Blocks – Components, Props, State, Lifecycle Methods
First, let’s quickly talk about React’s app-building blocks. Components, props, state, and lifecycle methods are what you need to be comfortable with as a beginner. They each have a particular purpose and allow you to control how your application renders.
Components are building blocks of React apps. They contain HTML and use state or props to render differently when their data changes. Props, which stand for properties, allow you to pass information from parent components to children. On the other hand, lifecycle methods describe actions that should be performed at different stages of an app’s life cycle, such as when it is being unmounted. To get started with react, students need to learn these basics first to have a solid foundation upon which to build more advanced skills later.
Styling React Apps
React apps are essentially reusable UI components. But it’s still essential to have consistency across all of your apps. In React, you can achieve a similar level of consistency using style sheets called CSS-in-JS or SSR CSS.
React training also offers a great way to dynamically render components when required. Just use ReactDOM. Generate (), providing it with a component name, just like above. The result will be rendered in place of #myDiv. Any props that you include will be passed along to your dynamically-rendered component.
Note that due to browser limitations, the DOM element itself ( #myDiv ) must have already been in place before you call ReactDOM.render() or else ReactDOM will attempt to create it (and fail). As mentioned above, specific attributes are required on any DOM element built by React; if you try and leave them out, it will throw an error telling you what’s missing.
Server-Side Rendering (SSR)
Server-side rendering is one of those react training features that make you go wow, but it also seems difficult to implement. SSR allows developers to render React components on a server to pre-render HTML elements and send them down as plain text, thus increasing performance and decreasing load times.
If you’re not interested in working with SSR, no worries—you don’t have to use it! But if you want your app’s content to load faster or be mobile-friendly, SSR could be right up your alley.
Routing in React Apps
As with many aspects of React training development, there are plenty of options for routing – we’ll walk through what’s available and why you might choose each one. We’ll be using react-router version 4, but most solutions use similar APIs and components.
What is the Fastest Way to Learn React?
While you can learn to React independently, the fastest way to learn is with a course from online websites. These courses help beginners jump in and start coding React apps from the first day. They will teach you how to build real-world projects and why React is so much better than the status quo. Learn more about our React training course, or get started today!
Is React Better or Angular?
Angular and React are both popular frameworks for building web apps. Angular and React have many similarities, so it’s not always easy to figure out which one is better. Here we look at three main areas where Angular and React differ: community, performance, and flexibility. If you’re looking to decide between Angular or React as your framework of choice, you’ll want to consider these factors.
Is React in Demand?
Microsoft has made significant investments in React training, contributing over 80 engineers to create a cross-platform version of it called React native. In other words, we can say that React is one of those technologies you should keep an eye on! In fact, according to CareerBuilder’s recent report, Employer Skills Outlook 2018 trends show that demand for both frontend and backend developers is increasing around 10% each year.
Learning to build with React can be daunting if you’re not sure where to start, but there are many resources to help make learning React easier. This React tutorial walks you through the basics of building components from the very beginning, and by the end, you’ll know how to use React in your applications. If you want to learn about more advanced topics like Hooks, Context, Error-Boundaries, and Portals along with Redux, check out this course on our website about building apps with React training and Redux.
