Deploy to Cloudflare

OpenStory deploys to Cloudflare Workers, using D1 (SQLite) for the database and R2 for media storage.

One-Click Deploy

The deploy button clones the repo into your GitHub/GitLab account, provisions the resources declared in wrangler.jsonc, prompts for the secrets listed in .dev.vars.example, and sets up CI for your copy.

The created repo is an independent clone, not a fork — there's no upstream link for GitHub's "Sync fork" button. To pull future OpenStory updates into a button-deployed copy, add the upstream remote manually (git remote add upstream https://github.com/openstory-so/openstory && git pull upstream main). If you'd rather start from a real fork, fork on GitHub first, then connect the fork to Workers Builds in the Cloudflare dashboard (or deploy from a local clone with bun setup --prod).

AI keys (FAL_KEY, OPENROUTER_KEY) are deliberately not part of the deploy prompts — every field in that dialog is mandatory, and a placeholder value would be worse than none. Add them after deploy, either per team in the app (Settings → API Keys) or server-wide with wrangler secret put.

Guided Setup

From your own clone, bun setup --prod walks through everything interactively: production env vars (.env.production), R2 domains + CORS, optional services, pushing secrets to Cloudflare and GitHub, and the first deploy. bun setup --deploy re-runs just the secrets-push + deploy phase, and bun setup --pr-preview pushes preview secrets to the GitHub staging environment used by PR preview deploys.

Prerequisites

• A Cloudflare account
• Wrangler CLI (installed as a dev dependency — use bunx wrangler)
• CLOUDFLARE_ACCOUNT_ID and CLOUDFLARE_API_TOKEN available in your environment

wrangler.jsonc

Bindings live in wrangler.jsonc at the repo root:

• DB — D1 database (openstory-prd)
• R2_PUBLIC_ASSETS_BUCKET — public assets (served via custom domain)
• R2_STORAGE_BUCKET — private storage for generated media

The Worker entry point is src/server.ts with nodejs_compat enabled.

Build & Deploy

Upstream production (openstory-so/openstory → the openstory worker) deploys through Workers Builds — the same mechanism Deploy-to-Cloudflare button clones use, so upstream dogfoods the exact pipeline users get. Workers Builds is wrangler-authenticated, so the prod path needs no Cloudflare secrets in GitHub. The dashboard configuration (the only deploy state not versioned in the repo):

• Repository / branch: openstory-so/openstory, main
• Build command: bun run build
• Build env vars: CLOUDFLARE_ENV=production (bakes the [env.production] block into dist/server/wrangler.json), VITE_R2_PUBLIC_ASSETS_DOMAIN, VITE_PUBLIC_POSTHOG_PROJECT_TOKEN, VITE_PUBLIC_POSTHOG_HOST
• Deploy command: bun run deploy:production — flatten migrations → wrangler d1 migrations apply DB --env=production --remote → wrangler deploy. The plain wrangler deploy picks up the flattened dist/server/wrangler.json via .wrangler/deploy/config.json; the --env flag matters only for the migrate step, which reads the source wrangler.jsonc.

For a manual deploy from a local checkout:

# Generate Worker types from wrangler.jsonc
bun cf:typegen

# Deploy to production (typegen, CLOUDFLARE_ENV=production build, migrate, wrangler deploy)
bun cf:deploy:prd

Database Migrations

Remote databases are migrated with wrangler d1 migrations apply (tracked in wrangler's d1_migrations table). drizzle-kit only generates migrations (bun db:generate); it never touches a remote database.

Because drizzle-kit emits nested <timestamp>_<name>/migration.sql files that wrangler can't read, scripts/flatten-migrations.ts renders them to flat drizzle/migrations-wrangler/*.sql (gitignored) first. The relevant scripts run it automatically:

bun run deploy             # flatten → wrangler d1 migrations apply DB --remote → wrangler deploy
                           # (what Deploy to Cloudflare button clones run)
bun run deploy:production  # same, but --env=production on the migrate step
                           # (what upstream's Workers Builds runs)
bun db:migrate:prd         # flatten → wrangler d1 migrations apply DB --env=production --remote

• Button deploys: the deploy package script is picked up as the deploy command and re-runs on every push, so new migrations apply idempotently. It references the binding name DB (not the database name) so it works whatever the user named their database.
• Upstream production (Workers Builds): deploy:production is the configured deploy command — identical to deploy except the migrate step targets the [env.production] D1.
• PR previews: CI applies migrations with wrangler d1 migrations apply DB --remote after patching the PR's database id into the config.
• Local dev / e2e: unchanged — drizzle-orm's migrator applies the nested files directly against the Miniflare binding (bun db:migrate:local).

Migrations must stay backwards-compatible for the moment between migrate and deploy, and the D1 table-rebuild CASCADE trap (see CLAUDE.md) applies to every remote apply path.

Seeding

There are no CI seed steps: the worker self-seeds system templates on first request (src/server.ts → src/lib/db/seed-system-templates.ts). A hash of the template definitions is stored in app_metadata; when it matches, the check is a single SELECT per isolate, and when it doesn't (fresh database, or a deploy that changed templates) the idempotent sync runs once. bun db:seed:local / bun scripts/seed.ts --test reuse the same module for local setup.

Secrets

Secrets are pushed to the Worker via wrangler secret bulk. The full list is defined in .github/workflows/deploy-cloudflare.yml. Core secrets include:

Variable	Description
BETTER_AUTH_SECRET	Better Auth signing secret
VITE_APP_URL	Public URL of the deployment
FAL_KEY	fal.ai API key for image/video generation
OPENROUTER_KEY	OpenRouter API key for LLM script analysis
GOOGLE_CLIENT_ID / GOOGLE_CLIENT_SECRET	Google OAuth credentials
EMAIL_FROM	Sender address for transactional email (domain onboarded in Cloudflare Email Service)

Prod database cutover (velro-prd → openstory-prd)

One-time runbook for #897: the production D1 predates the project rename (the account still calls it velro-prd) and its migration history lives in drizzle's __drizzle_migrations table, which wrangler doesn't read. D1 has no rename, so the move is a recreate — which also gives the new database a fully native d1_migrations history with no baselining:

# 1. Snapshot (also the import source). Quiet window: writes after this are lost.
bunx wrangler d1 export velro-prd --remote --output=backup.sql

# 2. Create the fresh DB and flip wrangler.jsonc to it FIRST:
#    set [env.production].d1_databases[0].database_id to the new DB's id
#    (keep database_name openstory-prd). Unlike `d1 export`/`execute`,
#    `d1 migrations apply` resolves ONLY from wrangler config — it can't
#    look a database up by name, and without the flip `--env=production`
#    would target the old velro id.
bunx wrangler d1 create openstory-prd
# ... edit wrangler.jsonc ...

# 3. Apply all migrations to the empty DB (rebuild-pattern migrations in our
#    history are CASCADE-safe with no rows). Same command prod CI runs:
bun db:migrate:prd

# 4. Data-only import. Three transforms on the raw export:
#    - drop drizzle's tracking rows (that table doesn't exist in the new DB —
#      wrangler's d1_migrations replaces it)
#    - reorder tables parent-first: D1 ingests large files in multiple
#      internal transactions, the dump's single leading
#      `PRAGMA defer_foreign_keys=TRUE` doesn't span them, and the export's
#      alphabetical order (`account` before `user`) fails at a chunk commit
#      with "FOREIGN KEY constraint failed" and rolls the import back.
#      Parent-first order needs no deferral, so chunking can't break it.
bunx wrangler d1 export velro-prd --remote --no-schema --output=data-raw.sql
grep -v '__drizzle_migrations' data-raw.sql > data.sql
bun scripts/reorder-d1-dump.ts data.sql data-ordered.sql
bunx wrangler d1 execute openstory-prd --remote --file=data-ordered.sql

# 5. Commit the wrangler.jsonc flip, merge, deploy. The deploy's
#    `wrangler d1 migrations apply` reports everything already applied.

# 6. Soak, then delete the old DB:
bunx wrangler d1 delete velro-prd

Merge order matters: run this runbook (through step 4) before merging the PR that contains the id flip. Merging first isn't destructive — wrangler sees an empty d1_migrations on the old DB, migration #1's CREATE TABLE fails against the existing tables, the file rolls back, and CI fails loudly with the previous deploy still serving — but it blocks deploys until the cutover is done.

Existing PR-preview databases also only have drizzle tracking — close and reopen the PR to get a fresh, wrangler-tracked preview database.

CI/CD

Production pushes to main deploy via Workers Builds (see Build & Deploy above). deploy-cloudflare.yml handles the PR previews, which stay on GitHub Actions because Workers Builds branch previews share production bindings — no per-PR D1 provisioning, no workflow-name namespacing, no teardown on close:

• PR previews: each PR gets its own Worker (pr-<number>) and D1 database (openstory-pr-<number>), with secrets pushed and the preview URL posted as a PR comment. Previews also get namespaced workflows (*-pr-<number>) and a video-export container application (pr-<number>-videoexportcontainer).
• Cleanup: closing a PR deletes the Worker, namespaced workflows, container application, and D1 database. Container apps are account-level and outlive the worker — skipping them blocks reopened-PR redeploys and accrues provisioned instances (see #1052).

Platform Detection

OpenStory automatically detects the deployment platform:

import { getDeploymentPlatform } from '@/lib/utils/environment';

const platform = getDeploymentPlatform();
// Returns: 'cloudflare' | 'local' | 'unknown'
