passport-linkedin-oauth2-proxied

LinkedIn OAuth2 strategy for Passport.js with configurable URLs. Authorization, token exchange, and profile requests go either directly to LinkedIn (default) or through a proxy by setting full URLs only (no base URL + paths).

Installation

npm install passport-linkedin-oauth2-proxied

Usage

Default (direct LinkedIn)

Omit URL options to use standard LinkedIn endpoints.

const Strategy = require("passport-linkedin-oauth2-proxied").Strategy;

passport.use(
  new Strategy(
    {
      clientID: process.env.LINKEDIN_CLIENT_ID,
      clientSecret: process.env.LINKEDIN_CLIENT_SECRET,
      callbackURL: process.env.LINKEDIN_CALLBACK_URL,
      scope: ["openid", "profile", "email"],
    },
    (accessToken, refreshToken, profile, done) => {
      return done(null, profile);
    },
  ),
);

Via proxy (full URLs)

Pass full URLs for each endpoint when using a proxy (Lambda, custom domain, etc.). If an option is omitted, the default LinkedIn URL is used.

passport.use(
  new Strategy(
    {
      clientID: process.env.LINKEDIN_CLIENT_ID,
      clientSecret: process.env.LINKEDIN_CLIENT_SECRET,
      callbackURL: process.env.LINKEDIN_CALLBACK_URL,
      scope: ["openid", "profile", "email"],
      authorizationURL: process.env.LINKEDIN_AUTHORIZATION_URL, // optional
      tokenURL: process.env.LINKEDIN_TOKEN_URL, // optional
      profileURL: process.env.LINKEDIN_PROFILE_URL, // optional
    },
    (accessToken, refreshToken, profile, done) => {
      return done(null, profile);
    },
  ),
);

Example env (use full URLs to your proxy, e.g. Lambda):

• LINKEDIN_AUTHORIZATION_URL=https://your-proxy.example.com/oauth/authorization
• LINKEDIN_TOKEN_URL=https://your-proxy.example.com/oauth/token
• LINKEDIN_PROFILE_URL=https://your-proxy.example.com/oauth/userinfo
