Function size

Example

const Aerospike = require('aerospike')
const lists = Aerospike.lists
const key = new Aerospike.Key('test', 'demo', 'mykey1')
// INSERT HOSTNAME AND PORT NUMBER OF AEROSPIKE SERVER NODE HERE!
var config = {
  hosts: '192.168.33.10:3000',
  // Timeouts disabled, latency dependent on server location. Configure as needed.
  policies: {
    write : new Aerospike.WritePolicy({socketTimeout : 0, totalTimeout : 0}),
    operate : new Aerospike.OperatePolicy({socketTimeout : 0, totalTimeout : 0})
  }
}
var ops = [
  lists.size('tags')
]

Aerospike.client(config).connect((error, client) => {
  if (error) throw error
  client.put(key, { tags: ['blue', 'yellow', 'pink'] }, (error) => {
    if (error) throw error
    client.operate(key, ops, (error, result) => {
      if (error) throw error
      console.log(result.bins.tags) // => { 3 }
      client.close()
    })
  })
})
