Migrating from 0.4.0 to 0.5.0

• Plugins and client plugins exported by the Convex Better Auth component are now exported under / plugins and / client / plugins respectively.
• A new crossDomain plugin is available.It’s functionality was previously baked into the convex plugin.
• Projects that were running v0.4.x will need to add the crossDomain plugin to their Better Auth client and server instances. convex / auth.ts

convex/auth.ts

import { convex, crossDomain } from "@erquhart/convex-better-auth/plugins";
import { betterAuth } from "better-auth";
import { GenericCtx } from "./_generated/server";

export const createAuth = (ctx: GenericCtx) =>
  betterAuth({
    // ...
    plugins: [crossDomain(), convex()],
  });

lib/auth-client.ts

import { createAuthClient } from "better-auth/react";
import {
  convexClient,
  crossDomainClient,
} from "@erquhart/convex-better-auth/client/plugins";

export const authClient = createAuthClient({
  // ...
  plugins: [crossDomainClient(), convexClient()],
});

The betterAuthComponent.authApi method is now betterAuthComponent.createAuthFunctions. All four named exports returned from betterAuthComponent.createAuthFunctions are now required, even if you’re only providing an onCreateUser hook. If you pass your DataModel to betterAuthComponent.createAuthFunctions, everything is now typed except for Ids, which still need to be asserted.Any other type assertions from before can be removed.

convex/users.ts

import { betterAuthComponent } from "./auth";
import type { DataModel } from "./_generated/dataModel";

export const { createUser, deleteUser, updateUser, createSession } =
  betterAuthComponent.createAuthFunctions<DataModel>({
    onCreateUser: async (ctx, user) => {
      return await ctx.db.insert("users", {});
    },
  });

• The authFunctions object (formerly authApi) is now passed to the BetterAuth constructor, and is no longer passed to convexAdapter.
• authFunctions is now typed using the AuthFunctions type.
• convexAdapter now takes the betterAuthComponent instance instead of the components.betterAuth object.

convex/auth.ts

import { BetterAuth, type AuthFunctions } from "@erquhart/convex-better-auth";
import { convex, crossDomain } from "@erquhart/convex-better-auth/plugins";
import { components, internal } from "./_generated/api";

const authFunctions: AuthFunctions = internal.users;

export const betterAuthComponent = new BetterAuth(
  components.betterAuth,
  authFunctions
);

export const createAuth = (ctx: GenericCtx) =>
  betterAuth({
    database: convexAdapter(ctx, betterAuthComponent),
    trustedOrigins: ["http://localhost:3000"],
    plugins: [convex(), crossDomain()],
  });
