Set `singlePortMode: true` to route **every** proxy through one shared listener instead — requests are dispatched to the right upstream by their `Host` header (and path). The port is configurable via `httpPort` (default `80`) and `httpsPort` (default `443`): ```ts const config: MultiProxyConfig = { https: false, singlePortMode: true, httpPort: 8080, proxies: [ { from: 'localhost:3000', to: 'foo.localhost' }, { from: 'localhost:3001', to: 'bar.localhost' }, { from: 'localhost:3002', to: '*.localhost' }, ], } ``` ```bash rpx start --single-port-mode --https-port 8443 ``` > When HTTPS is enabled and more than one proxy is configured, rpx already shares > a single `:443` listener automatically; `singlePortMode` extends that to the > HTTP-only and single-proxy cases and makes the port configurable. ### `changeOrigin` Set `changeOrigin: true` to rewrite the `Origin` request header to the upstream target — mirroring [`http-proxy`](https://github.com/http-party/node-http-proxy)'s option. Useful when the upstream enforces CORS or same-origin checks. ```ts const config: ProxyOptions = { from: 'localhost:5173', to: 'my-app.localhost', changeOrigin: true } ``` ```bash rpx start --from localhost:5173 --to my-app.localhost --change-origin ``` To learn more, head over to the [documentation](https://reverse-proxy.sh/). ## Production: multi-app gateway on one server rpx can front many apps on a single server, routing by `Host`, terminating TLS with real certificates, proxying WebSockets, and serving static sites — all from one listener on `:443`. ### WebSocket proxying WebSocket upgrades are proxied transparently for **every** route and mode — single proxy, multi-proxy, single-port, and the daemon. A request with `Upgrade: websocket` is accepted by rpx and piped to the upstream (`ws://`) in both directions, including the control-channel of a tunnel server that accepts the upgrade on any path. No configuration needed; it works wherever HTTP proxying works. This is what makes **dev-server HMR work over HTTPS**: Vite and friends open a `wss://` connection for hot-module reload, and rpx terminates the TLS and forwards it to the dev server's `ws://` endpoint. Point rpx at your dev server and HMR keeps working behind the custom HTTPS domain. ### Static file serving A route can serve a local directory instead of proxying. Set `static` (and omit `from`): ```ts const config: ProxyOptions = { proxies: [ // Proxy an app { from: 'localhost:3000', to: 'app.example.com' }, // Serve a built static site { to: 'docs.example.com', static: { dir: '/srv/docs/dist', cleanUrls: true, // /about.html -> 301 /about pathRewriteStyle: 'directory', // /about -> about/index.html ('flat' -> about.html) maxAge: 3600, // Cache-Control: public, max-age=3600 }, }, // Single-page app (client-side routing fallback to index.html) { to: 'spa.example.com', static: { dir: '/srv/spa/dist', spa: true } }, ], https: true, } ``` `static` also accepts a bare string shorthand for the directory: `{ to: 'site.example.com', static: '/srv/site' }`. ### Wildcard host routing Register a route for `_.example.com` and any `sub.example.com` matches it at request time. Lookup prefers an exact host match, then the most-specific (deepest-suffix) wildcard: ```ts const config: ProxyOptions = { proxies: [ { from: 'localhost:3002', to: '_.tunnel.example.com' }, // catch-all subdomains { from: 'localhost:3000', to: 'api.tunnel.example.com' }, // exact wins over the wildcard ], https: true, } ``` A bare apex (`example.com`) is **not** matched by `_.example.com`. ### Per-domain SNI certificates (Let's Encrypt) In production, serve a different real certificate per domain over SNI on one listener. Point the daemon at a directory of PEM files following the convention `.crt` / `.key`, with `_wildcard..crt` / `.key` mapping to the SNI server name `_.`: ```bash rpx daemon:start --certs-dir /etc/letsencrypt/rpx ``` Programmatically (or via an explicit map): ```ts import { runDaemon } from '@stacksjs/rpx' await runDaemon({ productionCerts: { certsDir: '/etc/letsencrypt/rpx', // or explicit per-server-name: domains: { 'api.example.com': { certPath: '/etc/ssl/api.crt', keyPath: '/etc/ssl/api.key' }, '_.example.com': { certPath: '/etc/ssl/wild.crt', keyPath: '/etc/ssl/wild.key' }, }, }, }) ``` When no usable production certs are found, rpx falls back to its local-CA / dev self-signed flow, so development is unchanged. ### On-demand TLS (lazy Let's Encrypt for unknown hosts) rpx can issue a real Let's Encrypt certificate for an **unknown host the first time it's needed** — handy for wildcard/tunnel setups where you don't know every subdomain ahead of time. Issuance is **gated** by an `ask` callback and/or an `allowedSuffixes` allowlist so it can't be abused into minting certs for arbitrary hostnames. ```ts import { runDaemon } from '@stacksjs/rpx' const daemon = await runDaemon({ // Seed the SNI set from any certs already on disk. productionCerts: { certsDir: '/etc/letsencrypt/rpx' }, onDemandTls: { enabled: true, email: 'admin@example.com', // Fast-path allowlist: any host under these suffixes is auto-issued. allowedSuffixes: ['apps.example.com'], // And/or decide dynamically (e.g. check a DB of registered tenants). ask: async host => isRegisteredTenant(host), // Where issued PEMs are written (.crt / .key). Defaults to the // productionCerts certsDir so issued certs survive restarts. certsDir: '/etc/letsencrypt/rpx', // staging: true, // use Let's Encrypt staging while testing }, }) // Pre-warm a cert programmatically (e.g. a tunnel server registering a new // subdomain) so the cert exists before the first browser hit: await daemon.ensureCert('alice.apps.example.com') ``` A host is approved for issuance when **either**`allowedSuffixes` matches**or** `ask(host)` resolves truthy. With neither configured, on-demand issuance refuses every host (fail-closed). Concurrent requests for the same host are de-duped so exactly one ACME order runs; failures are negatively cached briefly so rpx doesn't hammer Let's Encrypt's rate limits. #### How it works (and the Bun limitation it works around) The challenge is served over HTTP-01: when the ACME CA fetches `http:///.well-known/acme-challenge/`, rpx answers it from its own `:80` listener (same process, so the token is reachable the instant issuance registers it). > **Important:** Bun cannot mint a certificate _during_ the TLS handshake. > `Bun.serve` has no working `SNICallback`, and `server.reload({ tls })` does > **not** update certificates at runtime (verified on Bun 1.3.14 and 1.4.0). So > rpx implements on-demand TLS as **ask-gated issuance + listener recreate**, > not at-handshake issuance: > > 1. The first plaintext request for an approved-but-uncovered host on `:80` > triggers `ensureCert(host)` (fire-and-forget) before the HTTP→HTTPS > redirect. > 2. Once the cert is obtained and written, rpx rebuilds the `:443` listener > with the augmented SNI set — a sub-second `server.stop()` + re-`Bun.serve()` > (the rebind is retried briefly while the OS frees the port; in-flight > requests on the old listener drain first). > 3. The browser's subsequent HTTPS request finds the freshly-issued cert. > > For a host you know about ahead of time, call `daemon.ensureCert(host)` to > pre-warm the cert so even the very first HTTPS request is already covered. On-demand TLS is fully opt-in (`onDemandTls.enabled`); existing deployments are unaffected. ### On-demand sites (lazy dev servers, Valet-style) Stop running dev servers by hand. rpx can boot a project's dev server the **first time you open its URL** — visit `myapp.localhost` and rpx finds `~/Code/myapp`, runs its dev command (frontend + API + docs), shows a "starting…" page that reloads itself, and switches to the live app the moment it's ready. After the site goes idle it's stopped again, so a machine can "have" dozens of sites but only run the ones you're using. ```sh # Start the daemon once in on-demand mode (reads `onDemand` from rpx.config.ts) # then just open https://.localhost in the browser rpx daemon:start --on-demand # See everything rpx can boot (and what's currently live) rpx sites ``` A host resolves to a project two ways: an explicit `onDemand.sites` entry (exact host, then `_.suffix` wildcard), or by convention — `.` → `/` for each root (default `~/Code`) and dev TLD (`localhost`, `test`). A Stacks app (a `./buddy` launcher or `@stacksjs/_` dependency) boots frontend/`/api`/`/docs`; any project with a `dev` script boots `bun run dev`. ```ts // rpx.config.ts import type { OnDemandSitesConfig } from '@stacksjs/rpx' const onDemand: OnDemandSitesConfig = { enabled: true, roots: ['~/Code', '~/work'], // where to look for .localhost projects idleTimeoutMs: 30 _ 60_000, // stop a site after 30 min idle sites: [ // Explicit site for a project outside the roots / with a custom command. { to: 'api.localhost', dir: '~/services/api', command: 'bun run start', routes: [{ path: '/', portEnv: 'PORT', defaultPort: 4000 }] }, ], } export default { onDemand } ``` rpx picks a free port per backend, injects it into the command's env (`PORT`/`PORT_API`/`PORT_DOCS`), waits for the ready-gate ports to answer, then publishes the routes. Failed boots render a `502` with the site's log tail; a browser refresh retries. A booting host is added to the dev cert's SAN before its splash is served, so it's trusted HTTPS from the first hit. On-demand sites are opt-in for raw rpx (`--on-demand`) and run on the single-process daemon only (ignored with `--workers > 1`) — but **on by default in Stacks projects**. Define a project's startup by hand with a `rpx.site.json` (or a `"rpx"` key in its `package.json`) — `command`, `env`, and `routes` — which wins over auto-detection. See [the on-demand sites guide](./docs/features/on-demand-sites.md) for the full reference. ### Running on a real server (hosts management off + systemd) On a real server with real DNS, rpx should never touch `/etc/hosts` or set up local DNS resolvers. Disable all hosts management with `hostsManagement: false` (or the legacy `cleanup: { hosts: false }`): ```ts const config: ProxyOptions = { proxies: [/_ ... _/], https: true, hostsManagement: false, // no /etc/hosts reads/writes, no dev DNS } ``` Under systemd, run the daemon directly as root — when the process is already root it binds `:443`/`:80` without re-executing through `sudo`: ```ini # /etc/systemd/system/rpx.service [Service] ExecStart=/usr/local/bin/rpx daemon:start --certs-dir /etc/letsencrypt/rpx User=root Restart=always ``` ### The gateway entry point `rpx gateway` serves a whole box. It reads one `.json` fragment per app from a sites directory, merges them into a single configuration, and serves the result on `:80` and `:443`, so independent deploys compose instead of overwriting each other: ```bash rpx gateway --sites-dir /etc/rpx/sites.d ``` It prints its route count, source directory, port and TLS mode on startup, and the reason when it cannot start, so `journalctl` tells a gateway that came up with no routes apart from one that never came up. The same entry is `startGateway(options)` from the library. On Linux the CLI hangs at startup today ([#2267](https://github.com/stacksjs/rpx/issues/2267)), so run it there from a launcher that calls `startGateway`. Flags and merge rules: [Gateway mode](./docs/config.md#gateway-mode). ### HTTPS on a LAN (local CA) A host on a private network cannot get a public certificate, because an ACME challenge has to reach it and nothing routes there. `localCa` runs a Root CA on the box, mints one leaf covering the LAN hostnames and IP addresses you name, and serves it per SNI name and as the listener's default context, so an IP-literal URL (which sends no SNI) gets it too: ```bash rpx gateway --local-ca-dir /etc/rpx/local-ca --local-ca-hosts pi-stacks.local --local-ca-ips 192.168.1.20 --install-trust ``` Clients trust `/etc/rpx/local-ca/rpx-root-ca.crt` once. The full walkthrough, Raspberry Pi included, is in [LAN gateway](./docs/advanced/lan-gateway.md). ## Benchmarks rpx ships a reproducible benchmark suite that pits its real request-handling hot path against **caddy**and**nginx**, a raw `Bun.serve` proxy (the floor for the fetch-based approach), and a direct-to-origin baseline. Latency is measured with [mitata](https://github.com/evanwashere/mitata); throughput with [`oha`](https://github.com/hatoo/oha) under real concurrency. ```bash # from packages/rpx bun run bench # full suite (latency + throughput) bun run bench:latency # latency only bun run bench:throughput # throughput only bun run bench -n 100000 -c 100 --large # tune load / forward 100 KB bodies brew install caddy nginx oha # caddy & nginx are auto-skipped if absent ``` Representative single-machine run (Apple Silicon, plain HTTP, 50 concurrent, keepalive — your numbers will vary, read each proxy _relative to_ `direct` and `bun-raw` in the same run): Tiny-payload run (routing-bound — measures per-request overhead): | Target | Throughput | Latency (avg) | |----------|---------------:|--------------:| | direct | ~171,000 req/s | ~24 µs | | nginx | ~96,000 req/s | ~49 µs | | bun-raw | ~84,000 req/s | ~54 µs | | **rpx**|**~80,000 req/s**|**~59 µs** | | caddy | ~59,000 req/s | ~72 µs | At low concurrency rpx beats caddy and does real host routing + `X-Forwarded-*` on top; nginx (C) and a bare `Bun.serve` + `fetch` proxy lead raw throughput. HTML run (`bun run bench:html`, a ~16 KB page — the core real-world workload, body-bound): | Target | Throughput | |----------|--------------:| | direct | ~98,000 req/s | | nginx | ~77,000 req/s | | caddy | ~38,000 req/s | | bun-raw | ~27,000 req/s | | **rpx**|**~25,000 req/s**| On body-heavy responses the picture changes: nginx splices kernel→kernel (zero-copy), while Bun copies bodies through userspace — so **even a bare `Bun.serve` + `fetch` proxy (`bun-raw`) is ~3× behind nginx**. That gap is a Bun platform ceiling, not rpx-specific; rpx tracks right under it (~0.9× of bare fetch). See [`bench/FINDINGS.md`](./packages/rpx/bench/FINDINGS.md). ### Forwarding transport: a bounded keepalive pool rpx forwards upstream over a **pooled raw-socket HTTP/1.1 client** ([`src/proxy-pool.ts`](./packages/rpx/src/proxy-pool.ts)) rather than `fetch()`. Bun's `fetch()` churns upstream connections under load: even with a concurrency cap it opens and closes connections faster than the OS recycles ephemeral ports, they pile into `TIME_WAIT`, and throughput collapses ~15× (measured: ~11k `TIME_WAIT`, 45% errors at 400 concurrent). The pool caps the **total** open connections per host (`RPX_MAX_UPSTREAM_CONNS`, default 256) and **queues** excess requests, reusing a fixed set of keepalive sockets indefinitely — so there is no churn. The payoff is staying flat under load where a `fetch` proxy falls over: | Concurrency | `fetch`-based | **rpx** (pool) | |-------------|------------------:|-----------------:| | 50 | ~85,000 req/s | ~80,000 req/s | | 400 | ~4,800 req/s 💥 (45% errors) | ~34,000 req/s ✅ (0 errors) | (At 400 concurrent the pool held **10** `TIME_WAIT` sockets vs fetch's ~11,000.) The pool declines what it can't cleanly handle — streaming/large uploads, `Expect:`, protocol upgrades — falling back to `fetch()` transparently. Optional `RPX_UPSTREAM_TIMEOUT=` (default off) bounds a stalled upstream → `504`, resetting on every byte so it never severs a live stream (SSE/HMR/long-poll). See [`bench/README.md`](./packages/rpx/bench/README.md) and [`bench/FINDINGS.md`](./packages/rpx/bench/FINDINGS.md) for methodology, the apples-to-apples `--cores N` mode, and the full investigation. ### Scaling across cores (opt-in) A single rpx instance already serves ~80k small req/s on one core — far beyond any local workload — so single-process is the default. For production load on **Linux**, the daemon can run as a**multi-core cluster**: ```bash rpx daemon:start --workers 4 # or RPX_WORKERS=4 ``` A **coordinator** process owns the singletons — the lock, certs, on-demand ACME issuance, DNS, `/etc/hosts`, and the `:80` listener — and spawns N **worker** processes that bind `:443` with `reusePort` and serve traffic. The kernel load-balances accepted connections across the workers; when the coordinator issues a new on-demand cert it republishes the SNI set and `SIGHUP`s the workers to reload. Crashed workers are respawned; `SIGTERM` drains them all. > On **macOS**, `SO_REUSEPORT` doesn't load-balance across processes, so the > cluster falls back to effectively one active worker (correct, just not > parallel) — clustering is a Linux production feature. For a hand-rolled setup (or non-daemon `rpx start`), `RPX_REUSE_PORT=1` lets you run several independent instances behind your own supervisor (systemd / pm2 / a container replica set) sharing `:443`. It's **off by default** so a stray second instance still fails loudly with "port in use" rather than silently co-binding. The other direction, a small box such as a Raspberry Pi, is `RPX_WORKERS=1 RPX_REUSE_PORT=0` plus `maxTlsContexts` (default 256) to bound the certificates kept in memory; see the [environment variable reference](./docs/advanced/configuration.md#low-memory-setting). ## Testing ```bash bun test ``` ## Troubleshooting ### SSL Certificate Issues If you're experiencing SSL certificate issues when using RPX (like "Your connection is not private" browser warnings): 1. **Automatic Certificate Trust**: RPX automatically attempts to trust certificates during setup with a single password prompt. This works for most users. 2. **Use the certificate fix utility**: If you still see certificate warnings, run our automated certificate fixer: ```bash bun scripts/fix-certs.js ``` This script will: - Detect your operating system - Find all RPX certificates - Install them to the appropriate system trust stores - Provide browser-specific instructions 3. **Browser Workaround**: - **Chrome/Edge/Arc**: Type `thisisunsafe` on the warning page (you won't see what you're typing) - **Firefox**: Click "Advanced" then "Accept the Risk and Continue" - **Safari**: Click "Show Details", then "visit this website" > **Note**: After trusting certificates, restart your browser for changes to take effect. ## Changelog Please see our [releases](https://github.com/stacksjs/stacks/releases) page for more information on what has changed recently. ## Contributing Please review the [Contributing Guide](https://github.com/stacksjs/contributing) for details. ## Community For help, discussion about best practices, or any other conversation that would benefit from being searchable: [Discussions on GitHub](https://github.com/stacksjs/stacks/discussions) For casual chit-chat with others using this package: [Join the Stacks Discord Server](https://stacksjs.com/discord) ## Postcardware "Software that is free, but hopes for a postcard."
