Create the strategy instance

import { GitlabStrategy } from "remix-auth-gitlab";

let gitlabStrategy = new GitlabStrategy(
  {
    clientID: "YOUR_CLIENT_ID",
    clientSecret: "YOUR_CLIENT_SECRET",
    callbackURL: "https://example.com/auth/gitlab/callback",
  },
  async ({ accessToken, extraParams, profile }) => {
    // Get the user data from your DB or API using the tokens and profile
    return User.findOrCreate({ email: profile.emails[0].value });
  }
);

authenticator.use(gitlabStrategy);

Setup your routes

// app/routes/login.tsx
export default function Login() {
  return (
    <Form action="/auth/gitlab" method="post">
      <button>Login with Gitlab</button>
    </Form>
  );
}

// app/routes/auth/gitlab.tsx
import { ActionFunction, LoaderFunction, redirect } from "remix";
import { authenticator } from "~/auth.server";

export let loader: LoaderFunction = () => redirect("/login");

export let action: ActionFunction = ({ request }) => {
  return authenticator.authenticate("gitlab", request);
};

// app/routes/auth/gitlab/callback.tsx
import { LoaderFunction } from "remix";
import { authenticator } from "~/auth.server";

export let loader: LoaderFunction = ({ request }) => {
  return authenticator.authenticate("gitlab", request, {
    successRedirect: "/dashboard",
    failureRedirect: "/login",
  });
};
