Create a calendar feed people can subscribe to.
npm install ics-service
const express = require('express')
const generateIcs = require('ics-service/generate-ics')
const aboutRoute = require('ics-service/about')
const feedRoute = require('ics-service/feed')
const TITLE = 'some calendar feed'
const GENERATOR = 'my feed generator'
const events = [{
uid: 'a', title: 'A', description: 'A.',
location: 'Alamo Square, San Francisco, CA',
url: 'https://example.org/',
geo: {lat: 37.774703, lon: -122.432642, radius: 20},
categories: ['event'],
start: [2020, 8, 8, 8, 8],
duration: {hours: 1, minutes: 30},
status: 'CONFIRMED',
sequence: 1,
productId: GENERATOR,
}, {
uid: 'b',
title: 'B', description: 'B.',
start: [2020, 9, 9, 9, 9],
duration: {hours: 0, minutes: 45},
status: 'CONFIRMED',
sequence: 2,
productId: GENERATOR,
}]
const getIcs = feedUrl => generateIcs(TITLE, events, feedUrl)
const app = express()
app.use('/feed', feedRoute(getIcs))
app.use('/', aboutRoute(TITLE))
The events
array is passed into ics@3
almost unaltered, so check ics
's docs for more information on the format.
Optionally, you can pass an options object into generateIcs
, whose fields selectively override the following defaults:
{
// Send a Cache-Control header to let clients and/or shared caches (a.k.a. CDNS)
// cache the calendar feed. If you set this option to false, it won't be sent.
// see https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control
cacheControl: true,
// The number of seconds that a the calendar-feed is allowed to be cached.
// Note: With ics-service's next major version dump, this will be increased.
maxAge: 0,
// Send an ETag header, so that clients don't have to redownload the calendar feed.
// see https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/ETag
etag: true,
}
