Zeromq implementations in Typescript

## Patterns
- Dealer-Router (Brokerless Paranoid Pirate)
- Req-Rep
- Pub-Sub
- Pull-Push
## Features
- Automatic workers health-check
- Retry strategy
- Load balancing
- `async/await`
- Tracing (Zipkin integration)
## Protocol
```typescript
export type Request = {
body?: Body,
headers?: Headers,
path: Path,
};
```
```typescript
export type Response = {
body?: Body,
code: Code,
headers?: Headers,
};
```
## Dealer architecture
## Usage
Boot the server:
```typescript
import Router from "../src/Transport/Patterns/Dealer-Router/Router";
import {BatchRecorder, Tracer} from "zipkin";
import CLSContext from "zipkin-context-cls";
import {HttpLogger} from "zipkin-transport-http";
import * as zipkin from "zipkin";
import JSON_V2 = zipkin.jsonEncoder.JSON_V2;
const server: Router = new Router(
"tcp://127.0.0.1:3000",
"router",
{},
new Tracer({
ctxImpl: new CLSContext('zipkin'),
recorder: new BatchRecorder({
logger: new HttpLogger({
endpoint: 'http://localhost:9411/api/v2/spans',
jsonEncoder: JSON_V2
})
}),
localServiceName: 'customWorker',
}),
'customServer'
);
server.start(() => (
{
body: {
res: "ok",
worker: process.pid,
},
code: 0,
}
));
```
Connect with the client:
```typescript
import Dealer from "../src/Transport/Patterns/Dealer-Router/Dealer";
import {BatchRecorder, Tracer} from "zipkin";
import {HttpLogger} from "zipkin-transport-http";
import * as zipkin from "zipkin";
import JSON_V2 = zipkin.jsonEncoder.JSON_V2;
import CLSContext from "zipkin-context-cls"
import {Response} from "../src/Message/Response";
const cli: Dealer = new Dealer(
[
"tcp://127.0.0.1:3000",
"tcp://127.0.0.1:3001",
],
{},
3,
3000,
new Tracer({
ctxImpl: new CLSContext('zipkin'),
recorder: new BatchRecorder({
logger: new HttpLogger({
endpoint: 'http://localhost:9411/api/v2/spans',
jsonEncoder: JSON_V2
})
}),
localServiceName: 'client'
})
);
void (async () => {
await cli.start();
try {
const response: Response = await cli.request({
body: { wut: "????" },
path: "ping",
}, 100);
console.log(response);
} catch (e) {
console.log(e.message);
}
})();
```
Result:
