Adobe I/O Events Lib

Node Javascript API wrapping the Adobe I/O Events API.

Installing

$ npm install @adobe/aio-lib-events

Usage

  1. Initialize the SDK
const sdk = require('@adobe/aio-lib-events')

async function sdkTest() {
  //initialize sdk
  const client = await sdk.init('<organization id>', 'x-api-key', '<valid auth token>', '<options>')
}
  1. Call methods using the initialized SDK
const sdk = require('@adobe/aio-lib-events')

async function sdkTest() {
  // initialize sdk
  const client = await sdk.init('<organization id>', 'x-api-key', '<valid auth token>', '<options>')

  // call methods
  try {
    // use one of the get methods
    const result = await client.getSomething({})
    console.log(result)

  } catch (e) {
    console.error(e)
  }
}
  1. Using the poller for journalling
const sdk = require('@adobe/aio-lib-events')

async function sdkTest() {
  // initialize sdk
  const client = await sdk.init('<organization id>', 'x-api-key', '<valid auth token>', '<http options>')
  // get the journalling observable
  const journalling = client.getEventsObservableFromJournal('<journal url>', '<journalling options>')
  // call methods
  const subscription = journalling.subscribe({
    next: (v) => console.log(v), // Action to be taken on event
    error: (e) => console.log(e), // Action to be taken on error
    complete: () => console.log('Complete') // Action to be taken on complete
  })
  
  // To stop receiving events from this subscription based on a timeout
  setTimeout(() => subscription.unsubscribe(), <timeout in ms>)
}

One observable can have multiple subscribers. Each subscription can be handled differently. For more details on using the poller for Journalling check getEventsObservableFromJournal
