Dub

Dub is an open source modern link management platform for entrepreneurs, creators, and growth teams.

This plugins allows you to track leads when a user signs up using a Dub link. It also adds OAuth linking support to allow you to build integrations extending Dub's linking management infrastructure.

Installation

npm install @dub/better-auth

npm install dub

import { betterAuth } from "better-auth"
import { dubAnalytics } from "@dub/better-auth"
import { dub } from "dub"
 
export const auth = betterAuth({
    plugins: [
        dubAnalytics({
            dubClient: new Dub()
        })
    ]
})

Usage

Lead Tracking

By default, the plugin will track sign up events as leads. You can disable this by setting disableLeadTracking to true.

import { dubAnalytics } from "@dub/better-auth";
import { betterAuth } from "better-auth";
import { Dub } from "dub";
 
const dub = new Dub();
 
const betterAuth = betterAuth({
  plugins: [
    dubAnalytics({
      dubClient: dub,
      disableLeadTracking: true, // Disable lead tracking
    }),
  ],
});

OAuth Linking

The plugin supports OAuth for account linking.

First, you need to setup OAuth app in Dub. Dub supports OAuth 2.0 authentication, which is recommended if you build integrations extending Dub’s functionality Learn more about OAuth.

Once you get the client ID and client secret, you can configure the plugin.

dubAnalytics({
  dubClient: dub,
  oauth: {
    clientId: "your-client-id",
    clientSecret: "your-client-secret",
  },
});

And in the client, you need to use the dubAnalyticsClient plugin.

import { createAuthClient } from "better-auth/client";
import { dubAnalyticsClient } from "@dub/better-auth/client";
 
const authClient = createAuthClient({
  plugins: [dubAnalyticsClient()],
});

To link account with Dub, you need to use the dub.link.

const response = await authClient.dub.link({
  callbackURL: "/dashboard", // URL to redirect to after linking
});
