Uptime check

Checks uptime status of given url and provided keyword (optional).

How it works

Makes simple curl requests, gathers data on response and if requested also is looking for a keyword inside the document body.

If http code (response) is 2xx website is considered "up". If there is a keyword given for search, but the keyword cannot be found in the document body, website is considered "down".

v4 migration

From version 4 there is no userAgent option any more. If you used this, please migrate to:

check({
  headers: {
      'User-Agent': 'Your custom UA string',
  }
});

Example usage

check({
  url: 'https://example.com',
  keyword: 'example',
  redirectsLimit: 0
})
  .then(result => {
    /*
        see index.d.ts:Result
    */
  })
  .catch((err) => {
    /*
    err = '{Error} unexpected error.';
    */
  });
