Deploying

These are the instructions for deploying the RecFlare infrastructure to Cloudflare.

Why Cloudflare?

• Makes it easy to mirror RecNet Rec Room's backend is (was) a set of independent microservices, not one big monolith. Modeling each service as its own isolated Worker keeps RecFlare's structure close to the real thing — services scale, fail, and deploy independently — instead of collapsing everything into a single giant server.
• It's free/cheap to run a lot of service. Cloudflare Workers' free tier is keyed to usage, not to the number of Workers — so whether you deploy 1 service or all 36, the baseline cost is the same. You only start paying once usage crosses the free-tier limits. Additionally for development or maybe a private instance, the cost is near zero when not in use.
• Bundled Cloud CDN/Storage/SQL Cloudflare offers several cloud services we can rely on so the microservices can remain stateless (effectively read-only). They are also scalable by default so we don't need to worry about adding more disk space or upgrading services. If we start outgrowing the limits of these, well, we'll cross that bridge when we get to it. - D1 (a SQLite-compatible distributed database) - R2 (service like S3 for mass file hosting) - KV (service to distributed offer key/value stores) - Durable Objects (for a notifications hub)

Do I have to use Cloudflare?

Short answer, no. The services are plain Hono apps, so the request-handling code isn't tied to Cloudflare and can be deployed to other hosting providers — AWS, Vercel, Netlify, Fly.io, a plain Node/Bun server, and so on.

Long answer: the catch is everything around the code. RecFlare leans on Cloudflare for the deployment (Wrangler) and infrastructure layer — custom-domain routing per service, plus the storage bindings (D1, KV, R2, Durable Objects) the workers use. On another provider you'll need to provide equivalents (per-service routing, databases, object storage, a pub/sub or WebSocket layer) and wire up the deployment yourself.

So for example if you wanted to run on Vercel, you'd have to swap out KV for Redis, which are very similar services but would require small code changes.

Prerequisites

• node (modern)
• pnpm
• bun
• jq/awk/sed
• A Cloudflare account with a zone (domain) you control, for deploying.

Cloudflare's free plan is good enough for testing (100k worker requests/day) but the Rec Room client is very chatty. Frequent testing may exhaust that quota. The $5/month Worker plan includes 10M requests/month.

Getting Started

Install dependencies:

We use Just for convenience. This will install all dependencies across the microservices.

just install

Configure your custom domain:

Create a new .env file from the template:

cp .env.example .env

Edit .env and set RECFLARE_DOMAIN to your domain (or declare it with export RECFLARE_DOMAIN=rec.example.com)

(Optional) - per-app subdomain overrides come from RECFLARE_SUBDOMAINS (a JSON object, e.g. '{"playersettings":"settings"}'). This would be used if you wanted to merge two services together.

Create the storage resources:

The workers bind Cloudflare storage primitive. Create them once against your Cloudflare account, then record the IDs in .env. The committed wrangler.jsonc files carry "local" placeholders; the real IDs are spliced in at deploy time, so nothing in version control needs editing. Authenticate wrangler first (wrangler login).

wrangler d1 create recflare
wrangler kv namespace create RECFLARE_MATCH_PRESENCE
wrangler kv namespace create RECFLARE_PLAYER_SETTINGS
wrangler secrets-store store create recflare --scopes workers

Take the IDs output from the commands and put them into .env. (or with CI: RECFLARE_KV='{"RECFLARE_MATCH_PRESENCE":"<id>","RECFLARE_PLAYER_SETTINGS":"<id>"}')

The secrets store holds the shared JWT_SECRET HS256 signing key — every worker binds it so tokens signed by auth verify everywhere. Record its id in .env as RECFLARE_SECRETS_STORE, then set the key value once (all workers share it):

wrangler secrets-store secret create <store-id> --name JWT_SECRET --scopes workers --remote

Then apply the schema. just migrate will set up the database and populate it with data. This runs non-interactively, so be careful!

just migrate                 # migrate every worker that owns migrations
just migrate -F rooms        # or scope to one worker

R2 and Durable Objects

You only have to create the buckets:

wrangler r2 bucket create recflare-cdn
wrangler r2 bucket create recflare-img

Durable Objects

Nothing manual to do here. The object is created manually.

Run the development microservices:

⚠️ Note: This runs, but the name-server document still advertises the deployed hosts, not your local instances — so service discovery won't resolve locally. You can still call each service directly; each Wrangler instance runs on its own port. Maybe we can get this working somehow. @todo

just dev

Deploy or upgrade all workers

This will deploy or upgrade all workers to respective endpoints (*.example.com)

It will additionally run any necessary DB migrations.

Deploying requires wrangler to be authenticated against your Cloudflare account (wrangler login, or CLOUDFLARE_API_TOKEN / CLOUDFLARE_ACCOUNT_ID in the environment).

It requires the storage to be set up above, otherwise, deployments may fail.

You can always re-run it as often as you wish. DB migrations will only run once.

just install # Makes sure dependencies are up to date
just migrate # Runs DB migrations
just deploy # Deploy code

Optionally if you know there was only a change to a single service, you can use just [migrate|deploy] -F econ for example to only deploy the econ microservice.

Repository Structure

• apps/ - The service workers, one deployable Worker per subdirectory. Each has its own README.md, wrangler.jsonc, src/, and tests.
• packages/ - Shared libraries and configuration used across the workers.
  • @repo/hono-helpers - Hono framework utilities (logging, error handling).
  • @repo/tools - The runx CLI and the bin/ scripts each worker's package.json delegates to, so build/test/deploy stays consistent.
  • @repo/typescript-config, @repo/oxlint-config - Shared TS and lint config.
• turbo/generators/ - turbo gen templates for scaffolding new workers/packages.
• Justfile - Convenient aliases for common development tasks.

Available Commands

This repository uses a Justfile. Run just (or just --list) to see every command. Some key ones:

• just install - Install all dependencies.
• just dev - Start the dev server (context-aware: runs bun runx dev).
• just build - Build all workers.
• just test - Run tests (vitest).
• just check - Check code quality: deps, lint, types, format.
• just fix - Fix code issues: deps, lint, format, workers-types.
• just deploy - Deploy all workers to your domain.
• just new-worker (alias: just gen) - Scaffold a new service worker.
• just new-package - Scaffold a new shared package.
• just update deps - Update dependencies across the monorepo with syncpack.

For a single worker, scope with -F, e.g. just deploy -F playersettings.
