heads
Make parallel HEAD requests for an array of URLs and get back their HTTP status codes.
Why?
You've got a collection of URLs, and you want to make sure they're all working.
If you just need to check whether a URL is resolving, a HEAD
request is preferable
to a GET
because it only downloads the response headers instead of the whole
response body.
To keep things snappy, heads
makes multiple requests in parallel instead of one
at a time.
Installation
npm install heads --save
Usage
Heads expects an array of URL strings:
const heads = const urls = 'https://google.com' 'https://github.com' 'https://github.com/nonexistent-url'
heads(urls, [options])
urls
Type: string
, array
The URL(s) to check.
options
See the got
options.
Node-style callbacks are supported too:
If you just need to look up one URL, pass it as an argument instead of an array:
