I couldn't find a 'signUp with social' function when using authClient. Is there any reference I could use as a guide? Thank you.

I've only managed to reach the email login stage, but when I log in, I don't get an 'email not found' error. I thought it would create a new account automatically.

yeah i think When a user signs in with OAuth for the first time, Better Auth automatically creates a new account unless you mention a flag called disableImplicitSignUp is set to true. it is flag that controls the bevaiour on a newly signed user via oauth

here is how you do it -

socialProviders: {
  google: {
    clientId: "YOUR_GOOGLE_CLIENT_ID",
    clientSecret: "YOUR_GOOGLE_CLIENT_SECRET",
    disableImplicitSignUp: true, // Requires explicit sign-up request
  }
}

I received a message like this:
2025-04-09T15:05:49.434Z ERROR [Better Auth]: Provider did not return email. This could be due to misconfiguration in the provider settings.
I am using ElysiaJS and Next.js separately, here's my files:

// auth.ts (server)

export const auth = betterAuth({
  plugins: [openAPI({ disableDefaultReference: true }), username(), nextCookies(), oAuthProxy()],
  account: {
    accountLinking: {
      enabled: true,
    },
  },
  database: drizzleAdapter(db, {
    schema,
    provider: 'pg',
  }),
  emailAndPassword: {
    enabled: true,
    autoSignIn: false,
  },
  socialProviders: {
    github: {
      clientId: process.env.GITHUB_CLIENT_ID as string,
      clientSecret: process.env.GITHUB_CLIENT_SECRET as string,
      disableImplicitSignUp: false,
    },
    google: {
      clientId: process.env.GOOGLE_CLIENT_ID as string,
      clientSecret: process.env.GOOGLE_CLIENT_SECRET as string,
      disableImplicitSignUp: false,
    },
  },
  trustedOrigins: [WEB_URL],
});

// auth.ts (web)

export const authClient = createAuthClient({
  baseURL: "http://localhost:44720",
  plugins: [usernameClient()],
});

My goal is that when a user creates an account and signs up using their provider, they will automatically be redirected to a specific page, and their data will be stored in the database. Are there any methods I might have missed based on what I have already set up?

Yes, that's correct. I've tried it and saw that the user data is stored in the table. However, when I try to log in again, the provider informs me that the user is not found, including with GitHub.

First, I'm just learning, and I see this library is really complete and open source. I want to try implementing sign-up using Google and GitHub accounts. I haven't found many tutorials on YouTube yet. For now, just these two websites, before trying others. I've also created the Client ID and Client Secret. And I saw in the documentation that the tutorial only has the method authClient.signIn.social, but I thought there would be authClient.signUp.social.

So, when the user successfully registers or logs into the app using their social media account, I will delete that data and try with another social media account. That's my goal.

It turns out that Google works safely, previously because I didn't provide the callback URL. GitHub has a message saying that the email was not found.
