TA (somewhat) polished BetterAuth x Convex starter template with (decently) sane defaults
Hey ya'll,
as part of my work for the Hackathon, I decided to take some of the effort I put into the Auth layer and factor it out into an easy to start with Template.
Some things you get out of the box:
-
Full auth flows (passphrase, magic links, email codes, resets), all wired to Convex with shared schemas so client + server don't drift.
-
Social sign-in & linking (GitHub, Google, Apple) – just plug in envs and go.
-
Security helpers built in – zxcvbn passphrase strength meter, Have I Been Pwned plugin (Better Auth does have some neat plugins to say the least), email OTP.
-
Pre-styled UI using 9ui.dev primitives (think shadcn/ui but with Base UI + Tailwind v4 under the hood); can easily replace with shadcn/ui as they use the same CLI and I will probably improve the setup script to allow choosing between 9ui and shadcn/ui.
-
Rate limiting & audit trails baked in – destructive ops log to Convex automatically.
-
A realtime counter example so you can check Convex queries/mutations are working.
-
Email preview in dev mode (no setup required – just sends them to console).
-
Cron job - deletes temporary 24h username holds during verification.
-
Readme - An overly verbose readme that explains some decisions I made.
-
Easter eggs - Cause why not?
-
Solid DX: One command to setup everything.
Happy to get some feedback, harsh criticism is always welcome as well. Hope you can get some use out of it.
