Using the Better Auth component in "use node" context

🔑Auth✅Resolved

Coming from a different database, I'm in the process of migrating over to Convex (cloud, not self-hosted), and using Better Auth Convex component (local install) as auth solution.

Ideally I want to re-use the users's password hash, which are hashed using argon2idargon2id, this requires the node runtime instead of the default v8 runtime Convex uses.

When adding "use node""use node" at the top of the /convex/auth.ts/convex/auth.ts where I the betterAuthbetterAuth instance with the password hash override like so:

"use node";

export const createAuth = (ctx: GenericCtx<DataModel>, { optionsOnly } = { optionsOnly: false }) => {
  return betterAuth({
    ...
    emailAndPassword: {
      enabled: true,
      minPasswordLength: 12,
      password: {
        hash: async (password) => await argon2.hash(password),
        verify: async ({ hash, password }) => await argon2.verify(hash, password),
      },
    },
    ...
  });
};

"use node";

export const createAuth = (ctx: GenericCtx<DataModel>, { optionsOnly } = { optionsOnly: false }) => {
  return betterAuth({
    ...
    emailAndPassword: {
      enabled: true,
      minPasswordLength: 12,
      password: {
        hash: async (password) => await argon2.hash(password),
        verify: async ({ hash, password }) => await argon2.verify(hash, password),
      },
    },
    ...
  });
};

this will causes the following errors (not only from node:cryptonode:crypto also node:utilnode:util fsfs, pathpath and osos)

✘ [ERROR] Could not resolve "node:crypto"

    node_modules/argon2/argon2.cjs:1:49:
      1 │ const { randomBytes, timingSafeEqual } = require("node:crypto");

  The package "node:crypto" wasn't found on the file system but is built into node. Are you trying
  to bundle for node? You can use "platform: 'node'" to do that, which will remove this error.

It looks like you are using Node APIs from a file without the "use node" directive.
Split out actions using Node.js APIs like this into a new file only containing actions that uses "use node" so these actions will run in a Node.js environment.

this essentially means I can't override the password hash?
