ics.createEvent(event, (error, value) => {
if (error) {
console.log(error)
}
console.log(value)

})- Write an iCalendar file:
import { writeFileSync } from 'fs'
import ics from 'ics'
ics.createEvent({
title: 'Dinner',
description: 'Nightly thing I do',
start: [2018, 1, 15, 6, 30],
duration: { minutes: 50 }
}, (error, value) => {
if (error) {
console.log(error)
}
fs.writeFileSync(`${__dirname}/event.ics`, value)
})- Write multiple iCalendar files:
ics.createEvents functionality is on the roadmap, but in the meanwhile, you can do this easily
by following this example.
Returns an iCal-compliant text string. If callback is provided, returns a Node-style callback. If callback is not provided, returns an object with error and value properties.

[2000, 1, 5, 13, 5] (January 5, 2000 at 1pm) |
| duration | How long the event lasts. Object literal having form { weeks, days, hours, minutes, seconds } Either end or duration is required, but not both. |

Optional. Node-style callback.
function (err, value) {
if (err) {
// if iCal generation fails, err is an object containing the reason
// if iCal generation succeeds, err is null
}
