Create React App

First we need to create our react application using the following command in terminal

sudo npx create-react-app navbar --use-npm

After done or create React.js application in your local system. application structure looks like bellow.

navbar
├── node_modules
├── public
│   ├── favicon.ico
│   ├── index.html
│   └── manifest.json
├── src
│   ├── App.css
│   ├── App.js
│   ├── App.test.js
│   ├── index.css
│   ├── index.js
│   ├── logo.svg
│   └── serviceWorker.js
├── .gitignore
├── package.json
└── README.md

make the above files folder structure like that and remove un-necessary files and older.

Install-Package

after the create one fresh react application then install the following package in your react application's root directory.

npm install react-spring styled-components
// OR
nmp install react-spring
nmp install styled-components

you can also install packages in both ways.

Create Global.js

First, we need to create a Global.js file in the following directory path.

src/style/Global.js

import { createGlobalStyle } from 'styled-components';

const GlobalStyles = createGlobalStyle`

  @import url('https://fonts.googleapis.com/css?family=Montserrat:400,600&display=swap');;

  *,
  *::after,
  *::before {
    margin: 0px;
    padding: 0px;
    box-sizing: inherit;
  }

  html {
    font-size: 62.5%;
  }

  body {
    box-sizing: border-box;
    font-family: 'Montserrat', sans-serif;
  }
`;

export default GlobalStyles;

Create Brand.js

src/components/navbar/Brand.js

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

import logo from "../../logo.svg";

const Brand = () => {
  return (
    <Image src={logo} alt="Company Logo" />
  )
}

export default Brand

const Image = styled.img`
  height: 85%;
  margin: auto 0;
`;

Create BurgerMenu.js

src/components/navbar/BurgerMenu.js

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

const Burgermenu = (props) => {
  return (
    <Wrapper onClick={props.handleNavbar}>
      <div className={ props.navbarState ? "open" : "" }>
        <span> </span>
        <span> </span>
        <span> </span>
      </div>
    </Wrapper>
  );
}

export default Burgermenu;

const Wrapper = styled.div`
  position: relative;
  padding-top: .7rem;
  cursor: pointer;
  display: block;

  & span {
    background: #fdcb6e;
    display: block;
    position: relative;
    width: 3.5rem;
    height: .4rem;
    margin-bottom: .7rem;
    transition: all ease-in-out 0.2s;
  }

  .open span:nth-child(2) {
      opacity: 0;
    }

  .open span:nth-child(3) {
    transform: rotate(45deg);
    top: -11px;
  }

  .open span:nth-child(1) {
    transform: rotate(-45deg);
    top: 11px;
  }
`;

Create CollapseMenu.js

src/components/navbar/CollapseMenu.js

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

import { useSpring, animated } from 'react-spring';

const CollapseMenu = (props) => {
  const { open } = useSpring({ open: props.navbarState ? 0 : 1 });

  if (props.navbarState === true) {
    return (
      <CollapseWrapper style={{
        transform: open.interpolate({
          range: [0, 0.2, 0.3, 1],
          output: [0, -20, 0, -200],
        }).interpolate(openValue => `translate3d(0, ${openValue}px, 0`),
      }}
      >
        <NavLinks>
          <li><a href="/" onClick={props.handleNavbar}>link n1</a></li>
          <li><a href="/" onClick={props.handleNavbar}>link n2</a></li>
          <li><a href="/" onClick={props.handleNavbar}>link n3</a></li>
          <li><a href="/" onClick={props.handleNavbar}>link n4</a></li>
        </NavLinks>
      </CollapseWrapper>
    );
  }
  return null;
};

export default CollapseMenu;

const CollapseWrapper = styled(animated.div)`
  background: #2d3436;
  position: fixed;
  top: 4.5rem;
  left: 0;
  right: 0;
`;

const NavLinks = styled.ul`
  list-style-type: none;
  padding: 2rem 1rem 2rem 2rem;

  & li {
    transition: all 300ms linear 0s;
  }

  & a {
    font-size: 1.4rem;
    line-height: 2;
    color: #dfe6e9;
    text-transform: uppercase;
    text-decoration: none;
    cursor: pointer;

    &:hover {
      color: #fdcb6e;
      border-bottom: 1px solid #fdcb6e;
    }
  }
`;

Create Navbar.js

src/components/navbar/Navbar.js

import React from 'react'
import styled from "styled-components";
import { useSpring, animated, config } from "react-spring";

import Brand from "./Brand";
import BurgerMenu from "./BurgerMenu";
import CollapseMenu from "./CollapseMenu";

const Navbar = (props) => {
  const barAnimation = useSpring({
    from: { transform: 'translate3d(0, -10rem, 0)' },
    transform: 'translate3d(0, 0, 0)',
  });

  const linkAnimation = useSpring({
    from: { transform: 'translate3d(0, 30px, 0)', opacity: 0 },
    to: { transform: 'translate3d(0, 0, 0)', opacity: 1 },
    delay: 800,
    config: config.wobbly,
  });

  return (
    <>
      <NavBar style={barAnimation}>
        <FlexContainer>
          <Brand />
          <NavLinks style={linkAnimation}>
            <a href="/">link n1</a>
            <a href="/">link n2</a>
            <a href="/">link n3</a>
            <a href="/">link n4</a>
          </NavLinks>
          <BurgerWrapper>
            <BurgerMenu
              navbarState={props.navbarState} 
              handleNavbar={props.handleNavbar}
            />
          </BurgerWrapper>
        </FlexContainer>
      </NavBar>
      <CollapseMenu 
        navbarState={props.navbarState} 
        handleNavbar={props.handleNavbar}
      />
   </>
  )
}

export default Navbar

const NavBar = styled(animated.nav)`
  position: fixed;
  width: 100%;
  top: 0;
  left: 0;
  background: #2d3436;
  z-index: 1;
  font-size: 1.4rem;
`;

const FlexContainer = styled.div`
  max-width: 120rem;
  display: flex;
  margin: auto;
  padding: 0 2rem;;
  justify-content: space-between;
  height: 5rem;
`;

const NavLinks = styled(animated.ul)`
  justify-self: end;
  list-style-type: none;
  margin: auto 0;

  & a {
    color: #dfe6e9;
    text-transform: uppercase;
    font-weight: 600;
    border-bottom: 1px solid transparent;
    margin: 0 1.5rem;
    transition: all 300ms linear 0s;
    text-decoration: none;
    cursor: pointer;

    &:hover {
      color: #fdcb6e;
      border-bottom: 1px solid #fdcb6e;
    }

    @media (max-width: 768px) {
      display: none;
    }
  }
`;

const BurgerWrapper = styled.div`
  margin: auto 0;

  @media (min-width: 769px) {
    display: none;
  }
`;

Change in App.js

src/App.js

import React, { Component } from 'react'
import Navbar from "./components/navbar/Navbar";

import GlobalStyle from './style/Global';

class App extends Component {
  state = {
    navbarOpen: false
  }

  handleNavbar = () => {
    this.setState({ navbarOpen: !this.state.navbarOpen });
  }

  render() {

    return (
      <>
        <Navbar 
          navbarState={this.state.navbarOpen} 
          handleNavbar={this.handleNavbar}
        />
        <GlobalStyle />
      </>
    )
  }
}

export default App
