read params query react code example

Example 1: react parameter value from query string

// As far as I know there are three methods you can do that.
// Suppose an URL looks like this
// http://www.google.com.au?token=123

// 1) use a third library called 'query-string'.
import queryString from 'query-string'

const value=queryString.parse(this.props.location.search);
const token=value.token;
console.log('token',token)//123

// 2) Without library - Get a single query string
const query = new URLSearchParams(this.props.location.search);

const token = query.get('token')
console.log(token)//123

// 3) One liner - Get query string with '&' and without any library
const getQueryParams = () => window.location.search.replace('?', '').split('&').reduce((r,e) => (r[e.split('=')[0]] = decodeURIComponent(e.split('=')[1]), r), {});

Example 2: reactjs get url query params as object

new URLSearchParams(location.search).get("your_query_param_key")
______________________________________

    if(location && location?.search?.includes("registration_token")){
      const emailValue = new URLSearchParams(location.search).get("email")
      const regTokenValue = new URLSearchParams(location.search).get("registration_token")

      setValue("email", emailValue) 
      setValue("registration_token", regTokenValue) 
      console.log(regTokenValue, emailValue);
    }

Example 3: use query params react

const query = new URLSearchParams(this.props.location.search);

const token = query.get('token')
console.log(token)//123
