To add GitHub as a sign-in option to Helicone using NextAuth, you'll need to follow these steps, combining information from both the NextAuth documentation and the Helicone codebase:

1. Configure GitHub OAuth App

First, create a GitHub OAuth app. You can do this by following the instructions provided in the NextAuth documentation for the GitHub provider:

Go to GitHub - Creating an OAuth App.
Set the "Authorization callback URL" to your site's callback URL, which should match the format https://yourdomain.com/api/auth/callback/github.

2. Environment Variables

Next, add your GitHub OAuth app credentials to your environment variables. You'll need the Client ID and Client Secret provided by GitHub:

plaintext
1AUTH_GITHUB_ID=your_github_client_id
2AUTH_GITHUB_SECRET=your_github_client_secret

3. Update NextAuth Configuration

In your Helicone project, locate the NextAuth configuration file. If you're following the standard NextAuth setup, this will likely be in a file where you initialize NextAuth, such as .../pages/api/auth/[...nextauth].js or a similar setup.

Add GitHub as a provider by importing the GitHub provider from next-auth/providers and adding it to the providers array in your NextAuth configuration. Here's an example based on the NextAuth documentation:

javascript
1import NextAuth from "next-auth";
2import GitHub from "next-auth/providers/github";
3
4export default NextAuth({
5  // Configure one or more authentication providers
6  providers: [
7    GitHub({
8      clientId: process.env.AUTH_GITHUB_ID,
9      clientSecret: process.env.AUTH_GITHUB_SECRET,
10    }),
11    // ...add more providers here
12  ],
13  // Add additional NextAuth configuration here
14});

4. Handling Sign-in on the Frontend

In the Helicone frontend code, ensure you have a sign-in page or component that triggers the sign-in process. You can use the signIn method from next-auth/react to initiate the sign-in process with GitHub. For example:

javascript
1import { signIn } from "next-auth/react";
2
3// This can be triggered by a button click
4const handleSignIn = () => {
5  signIn("github"); // 'github' is the ID of the GitHub provider
6};

5. Testing

After configuring GitHub as a provider and setting up the sign-in logic, test the sign-in flow to ensure users can successfully authenticate with their GitHub accounts.

Additional Notes

Make sure to review the NextAuth documentation for more details on customization and advanced configurations.
Ensure your environment variables (AUTH_GITHUB_ID and AUTH_GITHUB_SECRET) are correctly set in your deployment environment.

By following these steps, you should be able to integrate GitHub as a sign-in option in your Helicone project using NextAuth.
