Setting Up Ollama with Firebase Auth

Setting up Ollama with Firebase Authentication may sound daunting, but fear not! Whether you're a seasoned developer or just venturing into the world of AI, this comprehensive guide will walk you through every step of the process smoothly. Plus, we’ll sprinkle in some expert tips & tricks along the way!

Why Choose Ollama with Firebase?

Before diving into the setup, believe it or not, the combination of Ollama & Firebase offers a robust solution for building AI-driven applications. Ollama provides support for running local Large Language Models (LLMs) like Gemma, while Firebase takes care of user authentication seamlessly. This duo can help enhance user engagement & maintain a secure application environment.

Benefits of Using Ollama with Firebase

Local Model Running: Ollama allows you to run models locally, avoiding dependency on online services.
Secure Authentication: Firebase Authentication is a tried & true method for securely managing users.
Customizability: Tailor the chatbots to fit your unique branding and needs.
Easy Integration: Ollama & Firebase can integrate nicely, streamlining the authentication for users.

Prerequisites

Before you jump into the setup, you’ll need to have a few things ready:

Node.js installed on your machine (version 14 or higher is typically recommended).
Firebase Account: If you don’t have one, create it by visiting Firebase.
Ollama Installed: Make sure you have Ollama set up correctly. To install Ollama on your machine follow instructions on Ollama's download page.

Step 1: Setting Up Firebase

First things first. You need to create a project on Firebase.

Head over to Firebase Console.
Click on Add Project. Name it accordingly (e.g., Ollama-Firebase-Demo).
For now, you can skip Google Analytics unless you feel adventurous!
Click on Create Project.

Step 1.1: Enable Authentication

Once your project is created, it’s high time to set up authentication:

In the Firebase console, navigate to the Build section & click Authentication.
Click on Get Started.
Go to the Sign-in Method tab.
Enable Email/Password provider and hit Save.

Now that we have our Firebase Authentication up and running, it’s time to configure Ollama!

Step 2: Install Ollama Plugin for Genkit

You’ll want to install the Ollama plugin using npm, and here's how:

1
2

bash
npm install --save genkitx-ollama

This plugin will help us interact with Ollama's functionalities within our Firebase setup.

Step 3: Configure Ollama Plugin

Once you have the plugin installed, you need to configure it to work with Firebase Authentication. We’ll ensure that Ollama is aware of your local model & can communicate with Firebase securely using tokens.

Step 3.1: Setting Up Ollama Server

Before you configure, you must run the Ollama server:

Pull the model you want to use, let’s say Gemma:
1 2bash ollama pull gemma
Start the Ollama server with:
1 2bash ollama run gemma

Step 3.2: Code Configuration

Let's write some code to set everything up: Create a new JavaScript file for your configuration. We'll name ours

configureOllama.js

: ```javascript import { ollama } from 'genkitx-ollama'; import { configureGenkit, isDevEnv } from '@genkit-ai/core';

export default configureGenkit({ plugins: [ ollama({ models: [ { name: 'gemma', type: 'generate', // specify either 'chat' | 'generate' }, ], serverAddress: 'http://127.0.0.1:11434' // default local address }), ], }); ```

Step 3.3: Authentication Authorization

To access remote deployments, Ollama requires specific headers for authentication:

javascript
ollama({
  models: [{ name: 'gemma' }],
  requestHeaders: { 'api-key': 'YOUR_API_KEY' },
  serverAddress: 'https://your-deployment-url',
});

When setting up Firebase, you’ll need to ensure that you have the necessary API key handy from your Firebase Console settings.

Step 3.4: Initialize Firebase Auth in Your App

Next, set up Firebase Authentication in your JavaScript file: ```javascript import { initializeApp } from 'firebase/app'; import { getAuth } from 'firebase/auth';

const firebaseConfig = { apiKey: 'YOUR_API_KEY', authDomain: 'YOUR_AUTH_DOMAIN', // more details here };

// Initialize Firebase const app = initializeApp(firebaseConfig); const auth = getAuth(app); ``` This will initialize the Firebase application along with the authentication service.

It’s time to tie everything together by implementing user sign-up/login. Let’s do the following:

For user sign-up, call

createUserWithEmailAndPassword

: ```javascript import { createUserWithEmailAndPassword } from 'firebase/auth';

const email = 'user@example.com'; // get from input field const password = 'yourpassword'; // get from input field

createUserWithEmailAndPassword(auth, email, password) .then((userCredential) => { const user = userCredential.user; console.log('User signed up:', user); }) .catch((error) => { const errorCode = error.code; const errorMessage = error.message; console.error('Error signing up:', errorMessage); }); ```

Step 4.2: Log In Existing Users

For logging in users, you can do the following: ```javascript import { signInWithEmailAndPassword } from 'firebase/auth';

signInWithEmailAndPassword(auth, email, password) .then((userCredential) => { const user = userCredential.user; console.log('User signed in:', user); }) .catch((error) => { const errorCode = error.code; const errorMessage = error.message; console.error('Error signing in:', errorMessage); }); ```

Step 5: Handling Authentication State

Firebase provides an easy way to manage user states. This means keeping track of whether a user is logged in or not. Use the

onAuthStateChanged

method: ```javascript import { onAuthStateChanged } from 'firebase/auth';

onAuthStateChanged(auth, (user) => { if (user) { console.log('User is signed in:', user); } else { console.log('No user is signed in.'); } }); ```

This will help you update the user interface based on whether the user is authenticated.

Step 6: Test Everything

At this point, you should be ready to run your application locally. Check if everything is configured correctly:

Start your Ollama server:
1 2bash ollama run gemma
Run your application & test the sign-up & sign-in processes.
If everything works smoothly, GREAT! You've successfully set up Ollama with Firebase Auth!
