A sample Remix Application showing account creation, login, logout and forgot password using Firebase

check out video here: https://www.youtube.com/watch?v=ZUVztkkY218

• the application uses the firebase client SDK to get the token from user authentication and saves it in a cookie on the server, using the firebase-admin SDK sdk to verify the token in the cookie is still valid
• add values to the app/firebase-config.json file to support client side API
• for the server, you will need to download the service account information into a file app/service-account.json

• cannot happen on the server so were do the login on the client side and then pass the idToken to the server to create the same cookie as we do with a normal login.
• use the useFetcher hook to call the ActionFuntion and pass appropriate properties as formData

// login.jsx - client
const signInWithGoogle = () => {
  const provider = new GoogleAuthProvider();
  signInWithPopup(auth, provider)
    .then(async (res) => {
      const idToken = await res.user.getIdToken();
      fetcher.submit(
        {
          "idToken": idToken,
          "google-login": true,
        },
        { "method": "post" }
      );
    })
    .catch((err) => {
      console.log("signInWithGoogle", err);
    });
};

This snippet of code is from the ActionFunction

let googleLogin = formData.get("google-login");
...
if (googleLogin) {
    const resp = await sessionLogin(formData.get("idToken"));
    return await setCookieAndRedirect(resp.sessionCookie);
} else {
    // handle emailPassword login
}

To get the icons to work I had to copy the assets into the public directory after install. The solutions i found in the discord channel lead me to believe there is no other solution at this time. See package.json for more details

From your terminal:

npm run dev

This starts your app in development mode, rebuilding assets on file changes.

First, build your app for production:

npm run build

Then run the app in production mode:

npm start

Now you'll need to pick a host to deploy it to.

If you're familiar with deploying node applications, the built-in Remix app server is production-ready.

Make sure to deploy the output of remix build

• build/
• public/build/

When you ran npx create-remix@latest there were a few choices for hosting. You can run that again to create a new project, then copy over your app/ folder to the new project that's pre-configured for your target server.

cd ..
# create a new project, and pick a pre-configured host
npx create-remix@latest
cd my-new-remix-app
# remove the new project's app (not the old one!)
rm -rf app
# copy your app over
cp -R ../my-old-remix-app/app app
