Email and password auth with Better Auth

Edit on Github

Better Auth is a framework-agnostic, TypeScript-first auth library. It needs a database; this uses Deno's built-in node:sqlite so there is nothing extra to install. Generate the tables once with `deno run -A npm:@better-auth/cli migrate`, then run this. Better Auth serves its routes under /api/auth.

import { betterAuth } from "npm:better-auth";
import { DatabaseSync } from "node:sqlite";

export const auth = betterAuth({
  database: new DatabaseSync("auth.db"),

Enable classic email and password accounts. Social providers can be added alongside this with socialProviders: { github: { ... } }.

  emailAndPassword: { enabled: true },
});

auth.handler takes a Request and returns a Response. Routes live under /api/auth, e.g. POST /api/auth/sign-up/email and /api/auth/sign-in/email.

Deno.serve((req) => auth.handler(req));

Run this example locally using the Deno CLI:

deno run -N -E -R -W https://docs.deno.com/examples/scripts/better_auth.ts
