React JS Get URL Params Without Router

React url parameter without router. In this tutorial, i am going to show you how to get parameters value from in URL without using react-router in react js app.

In this example, i will create a simple home page with query string url and get parameter value from it using this.props.location.search in react js app.

Get Parameter Value From Query String in React JS

  • Step 1 – Create React App
  • Step 2 – Install Query String and Bootstrap 4 Package
  • Step 3 – Create Home Component
  • Step 4 – Add Component in App.js

Step 1 – Create React App

Start your terminal and run the following command on your terminal to create a new react app:

npx create-react-app my-react-app

To run the React app, execute the following command on your terminal:

npm start

Check out your React app on this URL: localhost:3000

Step 2 – Install Query String and Bootstrap 4 Package

Run the following commands to install query string and boostrap 4 library into your react app:

npm install bootstrap --save
npm install query-string 

Then, Add react router and bootstrap.min.css file in src/App.js file:

import React from 'react';
import '../node_modules/bootstrap/dist/css/bootstrap.min.css';
import { BrowserRouter as Router, Switch, Route } from 'react-router-dom';
function App() {
  return (
    <div>
      <h2>How to Get Parameter in URL in React js with Router</h2>
    </div>
  );
}
export default App;

Step 3 – Create Home Component

Go to src directory of your react js app and create home component named Home.js. And add the following code into it:

import React from 'react'
import queryString from 'query-string'
class Home extends React.Component{
state = {
    site: 'unknown',
    subject: 'i dont know'
  }
  
  handleQueryString = () => {
    // Parsing the query string 
    // Using parse method
    let queries = queryString.parse(this.props.location.search)
    console.log(queries)
    this.setState(queries)
  }
  
  render() {
    return (
      <div style={{ margin: 200 }}>
          
      <p> WebSite: {this.state.site} </p>
  
          
      <p> Subject: {this.state.subject} </p>
  
        <button
          onClick={this.handleQueryString}
          className='btn btn-primary'>
          click me </button>
      </div>
    );
  }
}
  
export default Home;

Let’s assume you have the following URL “http://localhost:3000/?site=laratutorials&subject=get-query-string” that can be displayed into react js application. So, when you clicking on the button, you will get query string parameter on your react js app page.

Step 4 – Import Component in App.js

Import Home.js file in src/App.js file:

import React from 'react';
import '../node_modules/bootstrap/dist/css/bootstrap.min.css';
iimport queryString from 'query-string'
import Home from './Home'
function App() {  
    
  return (  
    <div className="App">  
      <Home />  
    </div>  
  );  
}  
export default App;
