# Changelog
## 2026-02-18 - 3.1.1 - fix(readme)
update README: add issue reporting/security section, document connection tokens and token utilities, clarify architecture/API and improve examples/formatting
- Added an 'Issue Reporting and Security' section linking to community.foss.global for bug/security reports and contributor onboarding.
- Documented connection tokens: encodeConnectionToken/decodeConnectionToken utilities, token format (base64url), and examples for hub and edge provisioning.
- Clarified Hub/Edge usage and examples: condensed event handlers, added token-based start() example, and provided explicit config alternative.
- Improved README formatting: added emojis, rephrased architecture descriptions, fixed wording and license path capitalization, and expanded example scenarios and interfaces.
## 2026-02-17 - 3.1.0 - feat(edge)
support connection tokens when starting an edge and add token encode/decode utilities
- Add classes.token.ts with encodeConnectionToken/decodeConnectionToken using a base64url compact JSON format
- Export token utilities from ts/index.ts
- RemoteIngressEdge.start now accepts a { token } option and decodes it to an IEdgeConfig before starting
- Add tests covering export availability, encode→decode roundtrip, malformed token, and missing fields
- Non-breaking change — recommend a minor version bump
## 2026-02-17 - 3.0.4 - fix(build)
bump dev dependencies, update build script, and refresh README docs
- Bumped devDependencies: @git.zone/tsbuild ^2.1.25 → ^4.1.2, @git.zone/tsbundle ^2.0.5 → ^2.8.3, @git.zone/tsrun ^1.2.46 → ^2.0.1, @git.zone/tstest ^1.0.44 → ^3.1.8, @push.rocks/tapbundle ^5.0.15 → ^6.0.3, @types/node ^20.8.7 → ^25.2.3
- Bumped runtime dependency: @push.rocks/qenv ^6.0.5 → ^6.1.3
- Changed build script: replaced "tsbuild --web --allowimplicitany" with "tsbuild tsfolders --allowimplicitany" (kept tsrust invocation)
- README updates: added RustBridge notes (localPaths must be full file paths), production binary naming conventions, rust core uses ring as rustls provider; removed emoji from example console output; clarified stunIntervalSecs is optional; renamed example status variable to edgeStatus; minor wire-protocol formatting and wording/legal text tweaks
## 2026-02-17 - 3.0.3 - fix(rust,ts)
initialize rustls ring CryptoProvider at startup; add rustls dependency and features; make native binary lookup platform-aware
- Install rustls::crypto::ring default_provider at startup to ensure ring-based crypto is available before any TLS usage.
- Add rustls dependency to remoteingress-bin and update remoteingress-core rustls configuration (disable default-features; enable ring, logging, std, tls12).
- Adjust TS classes to prefer platform-suffixed production binaries, add exact fallback names, and include explicit cargo output paths for release/debug.
- Cargo.lock updated to include rustls entry.
## 2026-02-16 - 3.0.2 - fix(readme)
Document Hub/Edge architecture and new RemoteIngressHub/RemoteIngressEdge API; add Rust core binary, protocol and usage details; note removal of ConnectorPublic/ConnectorPrivate (breaking change)
- Adds comprehensive README describing v3 Hub↔Edge topology and usage examples
- Introduces Rust core binary (remoteingress-bin) and RustBridge IPC via @push.rocks/smartrust
- Documents custom multiplexed binary frame protocol over TLS and PROXY protocol v1 for client IP preservation
- Notes STUN-based public IP discovery and cross-compiled linux/amd64 and linux/arm64 binaries
- Calls out removal/rename of ConnectorPublic/ConnectorPrivate to RemoteIngressHub/RemoteIngressEdge (breaking API change)
- Updates install instruction to use pnpm and expands API reference, events, and examples
## 2026-02-16 - 3.0.1 - fix(remoteingress)
no changes detected in diff; no code modifications to release
- No files changed in the provided diff.
- No release or version bump required based on current changes.
## 2026-02-16 - 3.0.0 - BREAKING CHANGE(remoteingress)
migrate core to Rust, add RemoteIngressHub/RemoteIngressEdge JS bridge, and bump package to v2.0.0

## 🏗️ Architecture
## Usage
`@serve.zone/remoteingress` uses a **Hub/Edge** topology with a high-performance Rust core and a TypeScript API surface:
`@serve.zone/remoteingress` is designed to facilitate the creation of secure private tunnels and enable access to private clusters from external sources, offering an integral part of the @serve.zone stack infrastructure. Below, we illustrate how to employ this package within your project, leveraging TypeScript and ESM syntax for modern, type-safe, and modular code.

```
### Prerequisites
| Component | Role |
|-----------|------|
| **RemoteIngressEdge** | Deployed at the network edge (e.g. a VPS or cloud instance). Accepts raw TCP connections and multiplexes them over a single TLS tunnel to the hub. |
| **RemoteIngressHub** | Deployed alongside DcRouter/SmartProxy in a private cluster. Accepts edge connections, demuxes streams, and forwards each to SmartProxy with a PROXY protocol v1 header so the real client IP is preserved. |
| **Rust Binary** (`remoteingress-bin`) | The performance-critical networking core. Managed via `@push.rocks/smartrust` RustBridge IPC — you never interact with it directly. Cross-compiled for `linux/amd64` and `linux/arm64`. |
Ensure that you have Node.js and TypeScript installed in your environment. Your project should be set up with TypeScript support, and you might want to familiarize yourself with basic networking concepts and TLS/SSL for secure communication.
### ✨ Key Features
### Importing and Initializing Connectors
- 🔒 **TLS-encrypted tunnel** between edge and hub (auto-generated self-signed cert or bring your own)
- 🔀 **Multiplexed streams** — thousands of client connections flow over a single tunnel
- 🌐 **PROXY protocol v1** — SmartProxy sees the real client IP, not the tunnel IP
- 🔑 **Shared-secret authentication** — edges must present valid credentials to connect
- 🎫 **Connection tokens** — encode all connection details into a single opaque string
- 📡 **STUN-based public IP discovery** — the edge automatically discovers its public IP via Cloudflare STUN
- 🔄 **Auto-reconnect** with exponential backoff if the tunnel drops
- 📣 **Event-driven** — both Hub and Edge extend `EventEmitter` for real-time monitoring
-**Rust core** — all frame encoding, TLS, and TCP proxying happen in native code for maximum throughput
`@serve.zone/remoteingress` offers two primary components: `ConnectorPublic` and `ConnectorPrivate`. Here's how to use them:
## 🚀 Usage
#### Setup ConnectorPublic
Both classes are imported from the package and communicate with the Rust binary under the hood. All you need to do is configure and start them.
`ConnectorPublic` acts as a gateway, accepting incoming tunnel connections from `ConnectorPrivate` instances and facilitating secure communication between the internet and your private network.
### Setting Up the Hub (Private Cluster Side)
```typescript
import { ConnectorPublic } from '@serve.zone/remoteingress';
import { RemoteIngressHub } from '@serve.zone/remoteingress';
// Initialize ConnectorPublic
const publicConnector = new ConnectorPublic({
tlsOptions: {
key: fs.readFileSync("<path-to-your-tls/key.pem>"),
cert: fs.readFileSync("<path-to-your-cert/cert.pem>"),
// Consider including 'ca' and 'passphrase' if required for your setup
},
listenPort: 443 // Example listen port; adjust based on your needs
const hub = new RemoteIngressHub();
// Listen for events
hub.on('edgeConnected', ({ edgeId }) => {
console.log(`Edge ${edgeId} connected`);
});
hub.on('edgeDisconnected', ({ edgeId }) => {
console.log(`Edge ${edgeId} disconnected`);
});
hub.on('streamOpened', ({ edgeId, streamId }) => {
console.log(`Stream ${streamId} opened from edge ${edgeId}`);
});
hub.on('streamClosed', ({ edgeId, streamId }) => {
console.log(`Stream ${streamId} closed from edge ${edgeId}`);
});
// Start the hub — it will listen for incoming edge TLS connections
await hub.start({
tunnelPort: 8443, // port edges connect to (default: 8443)
targetHost: '127.0.0.1', // SmartProxy host to forward streams to (default: 127.0.0.1)
});
// Register which edges are allowed to connect
await hub.updateAllowedEdges([
{ id: 'edge-nyc-01', secret: 'supersecrettoken1' },
{ id: 'edge-fra-02', secret: 'supersecrettoken2' },
]);
// Check status at any time
const status = await hub.getStatus();
console.log(status);
// {
// running: true,
// tunnelPort: 8443,
// connectedEdges: [
// { edgeId: 'edge-nyc-01', connectedAt: 1700000000, activeStreams: 12 }
// ]
// }
// Graceful shutdown
await hub.stop();
```
### Setting Up the Edge (Network Edge Side)
The edge can be configured in two ways: with an **opaque connection token** (recommended) or with explicit config fields.
#### Option A: Connection Token (Recommended)
A single token encodes all connection details — ideal for provisioning edges at scale:
```typescript
import { RemoteIngressEdge } from '@serve.zone/remoteingress';
const edge = new RemoteIngressEdge();
edge.on('tunnelConnected', () => console.log('Tunnel established'));
edge.on('tunnelDisconnected', () => console.log('Tunnel lost — will auto-reconnect'));
edge.on('publicIpDiscovered', ({ ip }) => console.log(`Public IP: ${ip}`));
// Single token contains hubHost, hubPort, edgeId, and secret
await edge.start({
token: 'eyJoIjoiaHViLmV4YW1wbGUuY29tIiwicCI6ODQ0MywiZSI6ImVkZ2UtbnljLTAxIiwicyI6InN1cGVyc2VjcmV0dG9rZW4xIn0',
});
```
#### Setup ConnectorPrivate
`ConnectorPrivate` establishes a secure tunnel to `ConnectorPublic`, effectively bridging your internal services with the external point of access.
#### Option B: Explicit Config
```typescript
import { ConnectorPrivate } from '@serve.zone/remoteingress';
import { RemoteIngressEdge } from '@serve.zone/remoteingress';
// Initialize ConnectorPrivate pointing to your ConnectorPublic instance
const privateConnector = new ConnectorPrivate({
publicHost: 'your.public.domain.tld',
publicPort: 443, // Ensure this matches the listening port of ConnectorPublic
tlsOptions: {
// You might want to specify TLS options here, similar to ConnectorPublic
}
const edge = new RemoteIngressEdge();
edge.on('tunnelConnected', () => console.log('Tunnel established'));
edge.on('tunnelDisconnected', () => console.log('Tunnel lost — will auto-reconnect'));
edge.on('publicIpDiscovered', ({ ip }) => console.log(`Public IP: ${ip}`));
await edge.start({
hubHost: 'hub.example.com', // hostname or IP of the hub
hubPort: 8443, // must match hub's tunnelPort (default: 8443)
edgeId: 'edge-nyc-01', // unique edge identifier
secret: 'supersecrettoken1', // must match the hub's allowed edge secret
});
// Check status at any time
const edgeStatus = await edge.getStatus();
console.log(edgeStatus);
// {
// running: true,
// connected: true,
// publicIp: '203.0.113.42',
// activeStreams: 5,
// listenPorts: [80, 443]
// }
// Graceful shutdown
await edge.stop();
```
### Secure Communication
### 🎫 Connection Tokens
It's imperative to ensure that the communication between `ConnectorPublic` and `ConnectorPrivate` is secure:
Connection tokens let you distribute a single opaque string instead of four separate config values. The hub operator generates the token; the edge operator just pastes it in.
- Always use valid TLS certificates.
- Prefer using certificates issued by recognized Certificate Authorities (CA).
- Optionally, configure mutual TLS (mTLS) by requiring client certificates for an added layer of security.
```typescript
import { encodeConnectionToken, decodeConnectionToken } from '@serve.zone/remoteingress';
### Advanced Usage
// Hub side: generate a token for a new edge
const token = encodeConnectionToken({
hubHost: 'hub.example.com',
hubPort: 8443,
edgeId: 'edge-nyc-01',
secret: 'supersecrettoken1',
});
console.log(token);
// => 'eyJoIjoiaHViLmV4YW1wbGUuY29tIiwi...'
Both connectors can be finely tuned:
// Edge side: inspect a token (optional — start() does this automatically)
const data = decodeConnectionToken(token);
console.log(data);
// {
// hubHost: 'hub.example.com',
// hubPort: 8443,
// edgeId: 'edge-nyc-01',
// secret: 'supersecrettoken1'
// }
```
- **Logging and Monitoring:** Integrate with your existing logging and monitoring systems to keep tabs on tunnel activity, performance metrics, and potential security anomalies.
Tokens are base64url-encoded (URL-safe, no padding) — safe to pass as environment variables, CLI arguments, or store in config files.
- **Custom Handlers:** Implement custom traffic handling logic for specialized routing, filtering, or protocol-specific processing.
## 📖 API Reference
- **Automation:** Automate the deployment and scaling of both `ConnectorPublic` and `ConnectorPrivate` instances using infrastructure-as-code (IAC) tools and practices, ensuring that your tunneling infrastructure can dynamically adapt to the ever-changing needs of your services.
### `RemoteIngressHub`
### Example Scenarios
| Method / Property | Description |
|-------------------|-------------|
| `start(config?)` | Spawns the Rust binary and starts the tunnel listener. Config: `{ tunnelPort?: number, targetHost?: string }` |
| `stop()` | Gracefully shuts down the hub and kills the Rust process. |
| `updateAllowedEdges(edges)` | Dynamically update which edges are authorized. Each edge: `{ id: string, secret: string }` |
| `getStatus()` | Returns current hub status including connected edges and active stream counts. |
| `running` | `boolean` — whether the Rust binary is alive. |
1. **Securing Application APIs:** Use `@serve.zone/remoteingress` to expose private APIs to your frontend deployed on a public cloud, ensuring that only your infrastructure can access these endpoints.
**Events:** `edgeConnected`, `edgeDisconnected`, `streamOpened`, `streamClosed`
2. **Remote Database Access:** Securely access databases within a private VPC from your local development machine without opening direct access to the internet.
### `RemoteIngressEdge`
3. **Service Mesh Integration:** Integrate `@serve.zone/remoteingress` as part of a service mesh setup to securely connect services across multiple clusters with robust identity and encryption at the tunnel level.
| Method / Property | Description |
|-------------------|-------------|
| `start(config)` | Spawns the Rust binary and connects to the hub. Accepts `{ token: string }` or `IEdgeConfig`. |
| `stop()` | Gracefully shuts down the edge and kills the Rust process. |
| `getStatus()` | Returns current edge status including connection state, public IP, and active streams. |
| `running` | `boolean` — whether the Rust binary is alive. |
For detailed documentation, API references, and additional use cases, please refer to the inline documentation and source code within the package. Always prioritize security and robustness when dealing with network ingress to protect your infrastructure and data from unauthorized access and threats.
**Events:** `tunnelConnected`, `tunnelDisconnected`, `publicIpDiscovered`
### Token Utilities
| Function | Description |
|----------|-------------|
| `encodeConnectionToken(data)` | Encodes `IConnectionTokenData` into a base64url token string. |
| `decodeConnectionToken(token)` | Decodes a token back into `IConnectionTokenData`. Throws on malformed or incomplete tokens. |
### Interfaces
```typescript
interface IHubConfig {
tunnelPort?: number; // default: 8443
targetHost?: string; // default: '127.0.0.1'
}
interface IEdgeConfig {
hubHost: string;
hubPort?: number; // default: 8443
edgeId: string;
secret: string;
}
interface IConnectionTokenData {
hubHost: string;
hubPort: number;
edgeId: string;
secret: string;
}
```
## 🔌 Wire Protocol
The tunnel uses a custom binary frame protocol over TLS:
```
[stream_id: 4 bytes][type: 1 byte][length: 4 bytes][payload: N bytes]
```
| Frame Type | Value | Direction | Purpose |
|------------|-------|-----------|---------|
| `OPEN` | `0x01` | Edge → Hub | Open a new stream; payload is PROXY v1 header |
| `DATA` | `0x02` | Edge → Hub | Client data flowing upstream |
| `CLOSE` | `0x03` | Edge → Hub | Client closed the connection |
| `DATA_BACK` | `0x04` | Hub → Edge | Response data flowing downstream |
| `CLOSE_BACK` | `0x05` | Hub → Edge | Upstream (SmartProxy) closed the connection |
Max payload size per frame: **16 MB**.
## 💡 Example Scenarios
### 1. Expose a Private Kubernetes Cluster to the Internet
Deploy an Edge on a public VPS, point your DNS to the VPS IP. The Edge tunnels all traffic to the Hub running inside the cluster, which hands it off to SmartProxy/DcRouter. Your cluster stays fully private — no public-facing ports needed.
### 2. Multi-Region Edge Ingress
Run multiple Edges in different geographic regions (NYC, Frankfurt, Tokyo) all connecting to a single Hub. Use GeoDNS to route users to their nearest Edge. The Hub sees the real client IPs via PROXY protocol regardless of which edge they connected through.
### 3. Secure API Exposure
Your backend runs on a private network with no direct internet access. An Edge on a minimal cloud instance acts as the only public entry point. TLS tunnel + shared-secret auth ensure only your authorized Edge can forward traffic.
### 4. Token-Based Edge Provisioning
Generate connection tokens on the hub side and distribute them to edge operators. Each edge only needs a single token string to connect — no manual configuration of host, port, ID, and secret.
```typescript
// Hub operator generates token
const token = encodeConnectionToken({
hubHost: 'hub.prod.example.com',
hubPort: 8443,
edgeId: 'edge-tokyo-01',
secret: 'generated-secret-abc123',
});
// Send `token` to the edge operator via secure channel
// Edge operator starts with just the token
const edge = new RemoteIngressEdge();
await edge.start({ token });
```
