@actyx/os-sdk

This is a JavaScript and TypeScript SDK for building ActyxOS apps. Currently, it wraps the ActyxOS Event Service and Console Service APIs in a simple client that can be used from within JavaScript and TypeScript apps.

Examples

Event Service

Subscribe to event streams

import { Client, Subscription } from '@actyx/os-sdk'

const ActyxOS = Client()

// callback style
ActyxOS.eventService.subscribe({
  subscriptions: Subscription.everything(),
  onEvent: event => {
    console.log('got event', event)
  }
})

// stream style
const eventStream = ActyxOS.eventService.subscribeStream({
  subscriptions: Subscription.everything(),
})
for await (const event of eventStream) {
  console.log('got event', event)
}

Publish events

import { Client, EventDraft } from '@actyx/os-sdk'

const ActyxOS = Client()

// callback style
ActyxOS.eventService.publish({
  eventDrafts: EventDraft.make('mySemantics', 'myName', { foo: 'bar' }),
  onDone: () => {
    console.log(`Published`)
  }
})

// promise style
await ActyxOS.eventService.publishPromise({
  eventDrafts: EventDraft.make('mySemantics', 'myName', { foo: 'bar' }),
})

Console Service

Simple logging

For simple logging needs, use the SimpleLogger which you can configure once and then use to log messages and, optionally, additional data:

import { Client } from '@actyx/os-sdk'

const ActyxOS = Client()

const logger: SimpleLogger = ActyxOS.consoleService.SimpleLogger({
  logName: 'myLogger',
  producerName: 'com.example.app1',
  producerVersion: '1.0.0'
})

logger.debug('this is a DEBUG message')
logger.warn('this is a WARNING message')
logger.info('this is an INFO message')
logger.error('this is an ERROR message')

logger.debug('This is a message with additional data', {foo: 'bar'})

Advanced (custom) logging

For more advanced, custom logging needs, use the log function directly:

import { Client } from '@actyx/os-sdk'

const ActyxOS = Client()

ActyxOS.consoleService.log({
  entry: {
    logName: 'myCustomLogger',
    message: 'this is a WARNING message',
    severity: LogSeverity.WARN,
    producer: {
      name: 'com.example.app1',
      version: '1.0.0'
    },
    additionalData: {
      foo: 'bar',
      bar: {
        foo: true,
      }
    },
    labels: {
      'com.example.app1.auth.username': 'john.doe',
      'com.example.app1.model.events': '10000',
    }
  },
  // Callback on successful logging
  onLogged: () => {
    // Do something
  },
  // Callback on error logging
  onError: err => {
    console.error(`error logging: ${err}`)
  }
})

There also is a corresponding version that returns a Promise:

import { Client } from '@actyx/os-sdk'

const ActyxOS = Client()

await ActyxOS.consoleService.logPromise({ /* log entry */ })

Advanced

Overriding the default client options

You can override the default client options by passing options (ApiClientOpts) when creating the client. If you only want to override specific options, use the default options (DefaultClientOpts) as shown in the following example:

import { Client, DefaultClientOpts } from '@actyx/os-sdk'

const clientOpts = DefaultClientOpts()
clientOpts.Endpoints.EventService.BaseUrl = 'http://10.2.3.23:4454/api'

const CustomActyxOS = Client(clientOpts)
