CodeSandbox link

You can find the full code for this tutorial at https://codesandbox.io/s/props-ig53j.

Create your data array

To start off, we'll need to create an array of objects, save it into a variable and export it directly. It's an array of objects, and each object should have the same keys. In our case, each key has a title and an image. Both them of strings.

export const menuData = [
    {
        title: "Courses",
        image: "https://designcode.io/images/icons/courses.svg"
    },
    {
        title: "Tutorials",
        image: "https://designcode.io/images/icons/tutorials.svg"
    },
    {
        title: "Livestreams",
        image: "https://designcode.io/images/icons/livestreams.svg"
    },
    {
        title: "Pricing",
        image: "https://designcode.io/images/icons/pricing.svg"
    }
];

Create the NavigationButton component

Then, we'll need to create our NavigationButton component. It'll take the title and the image as props. Learn more about props in the Props section of this handbook.

import React from "react";

const NavigationButton = (props) => {
    return (
        <div>
            <img src={props.image} />
            <p>{props.title}</p>
        </div>
    );
};

export default NavigationButton;

Loop through the data

All we have left to do is to loop through the data. Go in your App.js file and import the data at the top.

import { menuData } from "./menuData";

In the return body, we'll just map through the menuData array and return the NavigationButton for each object in the menuData array. We'll pass the image, as well as the title to the NavigationButton.

{menuData.map((data) => {
    return <NavigationButton image={data.image} title={data.title} />;
})}

And there it is! We now have a navigation bar like the one on Design+Code's website!

Final code with styling

You can style your components by using the styled-components package in your project. Learn more about it in the Styling in React section of this handbook.

The final code for App, using styled-components, is:

import React from "react";
import styled from "styled-components";

import { menuData } from "./menuData";
import NavigationButton from "./NavigationButton";

const App = () => {
    return (
        <Wrapper>
            <ButtonsWrapper>
                {menuData.map((data) => {
                    return <NavigationButton image={data.image} title={data.title} />;
                })}
            </ButtonsWrapper>
        </Wrapper>
    );
}

export default App

const Wrapper = styled.div`
    padding-top: 150px;
    margin: 0 auto;
`;

const ButtonsWrapper = styled.div`
    display: flex;
    justify-items: space-between;
    justify-content: center;
`;

The final code for NavigationButton, using styled-components, is:

import React from "react";
import styled from "styled-components";

const NavigationButton = (props) => {
    return (
        <Wrapper>
          <Image src={props.image} />
          <Title>{props.title}</Title>
        </Wrapper>
      );
};

export default NavigationButton;

const Wrapper = styled.button`
    display: flex;
    background: none;
    border: none;
    border-radius: 14px;
    padding: 10px 20px;
    transition: 0.3s ease-in-out;
    cursor: pointer;
    background-blend-mode: overlay;

    p {
        transition: 0.3s ease-in-out;
      }

    :hover {
        background: rgba(255, 255, 255, 0.2);
        box-shadow: 0px 20px 40px rgba(31, 47, 71, 0.25), 0px 1px 5px rgba(0, 0, 0, 0.1), inset 0 0 0 0.5px rgba(255, 255, 255, 0.4);

        p {
          color: #fff;
          transform: translateY(-1px);
        }
    }

    :focus {
        outline: none;
    }
`;

const Image = styled.img`
    margin: auto;
    height: 24px;
    width: 24px;
    object-fit: cover;
`;

const Title = styled.p`
    align-items: center;
    color: #ffffff;
    text-align: center;
    margin: auto;
    margin-left: 10px;
`;
