Fast DNS resolution caching results for a while.

Ping an URL for getting the canonical URL and store the result into a cache, respecting a Time-to-Live (TTL) for the next lookup.

Suggested TTL could be:

• Very Short: 300 seconds (5 minutes).
• Short: 3600 seconds (1 hour).
• Long: 86400 seconds (24 hours).
• Insanity: 604800 seconds (7 days).

This library support any data storage provided by keyv.

$ npm install @microlink/ping-url --save

const createPingUrl = require('@microlink/ping-url')
const cache = new Map()
const pingUrl = createPingUrl({ store: cache, ttl: 3600 })

;(async () => {
  await pingUrl('https://example.com') // MISS, do the request
  await pingUrl('https://example.com') // HIT, serve from cache!
})()

The payload returned by pingUrl will be response but without any stream object there.

See keyv#options.

See @keyvhq/memoize.

Type: object

Any option provided here will passed to got#options.
