# Deploy and Host a SvelteKit + Better Auth Starter on Railway

[![Deploy on Railway](https://railway.com/button.svg)](https://railway.com/new/template/sveltekit-better-auth-starter?utm_medium=integration&utm_source=button&utm_campaign=sveltekit-better-auth-starter)

A minimal, production-shaped SvelteKit app to build on: sign-in, password reset and email verification (Better Auth), Postgres via Drizzle with migrations, URL-locale i18n (`/`, `/pl`, `/de`, `/uk`, `/es`), transactional email, security headers, a health endpoint and one protected area. Source: [nomideusz/sveltekit-better-auth-starter](https://github.com/nomideusz/sveltekit-better-auth-starter).

## About Hosting a SvelteKit + Better Auth Starter

Two services: the SvelteKit server (Node adapter, built by Railpack from the repo) and PostgreSQL 17 on a volume. Every deploy runs Drizzle migrations and then creates the admin account from `ADMIN_EMAIL` / `ADMIN_PASSWORD` if it does not exist yet, so a fresh deploy has someone who can sign in without opening public sign-up. Sessions, password-reset and verification tokens live in Postgres (Better Auth tables). Email goes out over Resend's HTTP API when `RESEND_API_KEY` is set (Railway's Hobby plan blocks outbound SMTP ports, so this is the transport that works there) or over SMTP; with neither, reset and verification emails are logged instead of sent and the app runs fully. Built on `@sveltejs/kit` 3.0.0-next (pre-release) and Svelte 5.

## Common Use Cases

- The starting point for a SaaS, internal tool or member area that needs real auth on day one
- A reference for the SvelteKit 3 layout: config in `vite.config.ts`, declared env vars, `#lib` imports
- Multilingual sites: default locale un-prefixed, others at `//*`, one server hook

## Dependencies for SvelteKit + Better Auth Starter Hosting

- Bundled: PostgreSQL 17 on a volume
- Optional: a Resend API key (HTTP email — works on the Hobby plan) or SMTP credentials (needs a plan where outbound SMTP is allowed)

### Deployment Dependencies

- [Better Auth documentation](https://better-auth.com/docs)
- [Drizzle ORM documentation](https://orm.drizzle.team)
- [Template source on GitHub](https://github.com/nomideusz/sveltekit-better-auth-starter)

### Implementation Details

**Sign in at `/auth/login`** with `ADMIN_EMAIL` and the generated `ADMIN_PASSWORD` (read it in the service's Variables tab). Change it afterwards via "Forgot your password?" once email is configured (`RESEND_API_KEY` or SMTP).

Variable wiring:

- `DATABASE_URL = postgres://${{postgres.POSTGRES_USER}}:${{postgres.POSTGRES_PASSWORD}}@${{postgres.RAILWAY_PRIVATE_DOMAIN}}:5432/${{postgres.POSTGRES_DB}}?sslmode=disable` (private network)
- `ORIGIN = https://${{RAILWAY_PUBLIC_DOMAIN}}` (auth base URL and email links; change when you attach a custom domain)
- `BETTER_AUTH_SECRET` generated; `ADMIN_PASSWORD` generated
- `railway.toml` in the repo sets the build, pre-deploy (`migrate` + `bootstrap-admin`), start command and `/api/health`

Notes:

- Add your tables to `src/lib/server/db/schema.ts`, run `pnpm db:generate` locally, commit the migration; it applies on the next deploy.
- Public sign-up is off by default; set `ALLOW_SIGNUP=true` to open `/auth/signup` (new accounts get a verification email).
- Upgrade path: fork the repo, point the service at your fork.
