React Components example

In this tutorial, we're gonna look at how to create React Components (Nesting Components, too).

Related Posts:

I. Technologies

  • React 16
  • NodeJs 6.11.2
  • NPM 3.10.10
  • Yarn 1.5.1
  • Babel 6.24.1

    II. How to

    1. Create a Component

    To do this, we extend React.Component, then return template for component inside render() method
    class MyComponent extends React.Component {
    render() {
        return (
            <div>
                <h2>Java Sample Approach</h2>
                <h4>Java/JavaScript Technology - Spring Framework</h4>
            </div>
        )
    }
    }

    2. Create Nesting Component

    Nesting Component contains one or many Components. We use tags specified for nested Components like this:
    class MyComponent extends React.Component {
    render() {
        return (
            <div>
                <h2>Java Sample Approach</h2>
                <ChildOne />
                <ChildTwo />
                <ChildThree />
            </div>
        )
    }
    }

class ChildOne extends React.Component { ... }
class ChildTwo extends React.Component { ... }
class ChildThree extends React.Component { ... }

III. Practice

1. Overview

react-components-example-overview

We have 5 Components: NoteApp, Header, Notes, Note, Action.
NoteApp and Notes are nesting Components that contain other Components:

  • Notes contains 3 Note
  • NoteApp contains Header, Notes and Action

    2. Project Structure

    3. Step by Step

    3.0 Set up Environment

    We need NodeJs, Yarn and Babel to compile and run this example. Please visit Set up Environment for step by step.
