Installation

npm install --save react-linkedin-login-oauth2@latest

Overview

We will trigger linkedInLogin by using useLinkedIn (recommended) or LinkedIn (using render props technique) after click on Sign in with LinkedIn button, a popup window will show up and ask for the permission. After we accepted, the pop up window will redirect to redirectUri (should be LinkedInCallback component) then notice its opener about the authorization code Linked In provides us. You can use react-router-dom or Next.js's file system routing

Usage

First, we create a button and provide required props:

import React, { useState } from 'react';

import { useLinkedIn } from 'react-linkedin-login-oauth2';
// You can use provided image shipped by this package or using your own
import linkedin from 'react-linkedin-login-oauth2/assets/linkedin.png';

function LinkedInPage() {
  const { linkedInLogin } = useLinkedIn({
    clientId: '86vhj2q7ukf83q',
    redirectUri: `${window.location.origin}/linkedin`, // for Next.js, you can use `${typeof window === 'object' && window.location.origin}/linkedin`
    onSuccess: (code) => {
      console.log(code);
    },
    onError: (error) => {
      console.log(error);
    },
  });

  return (
    <img
      onClick={linkedInLogin}
      src={linkedin}
      alt="Sign in with Linked In"
      style={{ maxWidth: '180px', cursor: 'pointer' }}
    />
  );
}

If you don't want to use hooks. This library offer render props option:

import React, { useState } from 'react';

import { LinkedIn } from 'react-linkedin-login-oauth2';
// You can use provided image shipped by this package or using your own
import linkedin from 'react-linkedin-login-oauth2/assets/linkedin.png';

function LinkedInPage() {
  return (
    <LinkedIn
      clientId="86vhj2q7ukf83q"
      redirectUri={`${window.location.origin}/linkedin`}
      onSuccess={(code) => {
        console.log(code);
      }}
      onError={(error) => {
        console.log(error);
      }}
    >
      {({ linkedInLogin }) => (
        <img
          onClick={linkedInLogin}
          src={linkedin}
          alt="Sign in with Linked In"
          style={{ maxWidth: '180px', cursor: 'pointer' }}
        />
      )}
    </LinkedIn>
  );
}

Then we point redirect_url to LinkedInCallback. You can use react-router-dom or Next.js's file system routing

react-router-dom:

import React from 'react';
import { LinkedInCallback } from 'react-linkedin-login-oauth2';

import { BrowserRouter, Route } from 'react-router-dom';

function Demo() {
  return (
    <BrowserRouter>
      <Route exact path="/linkedin" component={LinkedInCallback} />
    </BrowserRouter>
  );
}

Next.js's file system routing:

// pages/linkedin.js
import { LinkedInCallback } from 'react-linkedin-login-oauth2';
export default function LinkedInPage() {
  return <LinkedInCallback />;
}

Support IE

Support for IE is dropped from version 2
