Usage

$3

First you need to create a new application in the Linkedin's developers page. Then I encourage you to read this documentation page, it explains how to configure your app and gives you useful information on the auth flow.
The app is mandatory in order to obtain a clientID and client secret to use with the Linkedin's API.

``ts
// linkedin.server.ts
import { createCookieSessionStorage } from 'remix';
import { Authenticator } from 'remix-auth';
import { LinkedinStrategy } from "remix-auth-linkedin";

// Personalize this options for your usage.
const cookieOptions = {
path: '/',
httpOnly: true,
sameSite: 'lax' as const,
maxAge: 24 60 60 1000 30,
secrets: ['THISSHOULDBESECRET_AND_NOT_SHARED'],
secure: process.env.NODE_ENV !== 'development',
};

const sessionStorage = createCookieSessionStorage({
cookie: cookieOptions,
});

export const authenticator = new Authenticator(sessionStorage, {
throwOnError: true,
});

const linkedinStrategy = new LinkedinStrategy(
{
clientID: "YOUR_CLIENT_ID",
clientSecret: "YOUR_CLIENT_SECRET",
// LinkedIn is expecting a full URL here, not a relative path
// see: https://learn.microsoft.com/en-us/linkedin/shared/authentication/authorization-code-flow?tabs=HTTPS1#step-1-configure-your-application
callbackURL: "https://example.com/auth/linkedin/callback";
},
async ({accessToken, refreshToken, extraParams, profile, context}) => {
/*
profile:
type LinkedinProfile = {
id: string;
displayName: string;
name: {
givenName: string;
familyName: string;
};
emails: Array<{ value: string }>;
photos: Array<{ value: string }>;
_json: LiteProfileData & EmailData;
} & OAuth2Profile;
*/

// Get the user data from your DB or API using the tokens and profile
return User.findOrCreate({ email: profile.emails[0].value });
}
);

authenticator.use(linkedinStrategy, 'linkedin');
