Installation

npm i react-linkedin-login-oauth2

Overview

We will create a Linked In button (using LinkedIn component), after clicking on this button, a popup window will show up and ask for the permission. After we accepted, the pop up window will redirect to a specified URI which should be routed to LinkedInPopUp component. It has responsible to notice our openning app the authorization code Linked In provides us. You can consider using react-router-dom as a possible solution.

Usage

First, we create a button and provide required props

import React, { Component } from 'react';

import { LinkedIn } from 'react-linkedin-login-oauth2';

class LinkedInPage extends Component {
  state = {
    code: '',
    errorMessage: '',
  };


  handleSuccess = (data) => {
    this.setState({
      code: data.code,
      errorMessage: '',
    });
  }

  handleFailure = (error) => {
    this.setState({
      code: '',
      errorMessage: error.errorMessage,
    });
  }
  
  render() {
    const { code, errorMessage } = this.state;
    return (
      <div>
        <LinkedIn
          clientId="81lx5we2omq9xh"
          onFailure={this.handleFailure}
          onSuccess={this.handleSuccess}
          redirectUri="http://localhost:3000/linkedin"
        >
          <img src={require('./assets/linkedin.png')} alt="Log in with Linked In" style={{ maxWidth: '180px' }} />
        </LinkedIn>
        {!code && <div>No code</div>}
        {code && <div>Code: {code}</div>}
        {errorMessage && <div>{errorMessage}</div>}
      </div>
    );
  }
}

export default LinkedInPage;

Then we define a route to redirect_url and pass LinkedInPopUp to it as follow:

import React, { Component } from 'react';
import { LinkedInPopUp } from 'react-linkedin-login-oauth2';

import { render } from 'react-dom';
import { BrowserRouter, Route, Switch } from 'react-router-dom';
import LinkedInPage from './LinkedInPage';

class Demo extends Component {
  render() {
    return (
      <BrowserRouter>
        <Switch >
          <Route exact path="/linkedin" component={LinkedInPopUp} />
          <Route path="/" component={LinkedInPage} />
        </Switch>
      </BrowserRouter>
    );
  }
}
