Sample code

const ieee1888 = require('ieee1888')
const moment = ieee1888.moment
const client = new ieee1888.Client('http://sample.org/axis2/services/FIAPStorage')

// callback
client.write([
    { id: 'http://test.io/path/id', value: 27, time: moment() },
    { id: 'http://test.io/path/id', value: 88.88, time: moment() },
    { id: 'http://test.io/test/value', value: 88.88, time: moment() }
], (err, rs) => {
    if (err) console.error(err)
    console.log(rs)
})

// promise
client.write([
    { id: 'http://test.io/path/id', value: 27, time: moment() },
    { id: 'http://test.io/path/id', value: 88.88, time: moment() },
    { id: 'http://test.io/test/value', value: 88.88, time: moment() }
])
.then(rs => {
    console.log(rs)
}).catch(err => {
    console.log(err)
})

// async await
(async () => {
    try {
        const rs = await client.write([
            { id: 'http://test.io/path/id', value: 27, time: moment() },
            { id: 'http://test.io/path/id', value: 88.88, time: moment() },
            { id: 'http://test.io/test/value', value: 88.88, time: moment() }
        ])
        console.log(rs);
    } catch (err) {
        console.log(err)
    }
})()

// fetch latest

    'http://test.io/path/id',
    'http://test.io/test/value'
])
.then(rs => {
