NPM Build Status

Passmarked is a suite of tests that can be run against any page/website to identify issues with parity to most online tools in one package.

The Terminal Client is intended for use by developers to integrate into their workflow/CI servers but also integrate into their own application that might need to test websites and provide realtime feedback.

All of the checks on Passmarked can be voted on importance and are open-sourced, to encourage community involvement in fixing and adding new rules. We are building the living Web Standard and love any contributions.

Synopsis

The rules checked in this module are:

  • alpn - ALNP negotiation could not be performed, meaning the protocol is disabled.
  • bad - Any of the links in the HAR returned a status code other than REDIRECT/INFO/OK
  • cache.scope - The cache-control header specified that the resource is cacheable by both private and public. Which may cause unindentended behaviour.
  • cache.unknown - Unknown options configured apart from known types - developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control. This will only be triggered on "local" resources, as that is what the user can fix. And browsers will tend to ignore the other options on third parties. This is more the rule being precise.
  • cache.internal - Caching on the internal resource is not configured
  • cache.external - Caching on the external (third party domain) resource is not configured
  • expire.date - The expire header contained a invalid date
  • expire.internal - The caching duration on a local resource is configured for less than 2 days at a minimum
  • expire.external - The caching duration on a external resource is configured for less than 6 hours at a minimum
  • charset - Charset could have been set earlier in the headers of the response.
  • consistent - Any of the same assets are returned from different urls that does not allow caching.
  • favicon.size - Favicon is bigger than 10KB.
  • favicon.exists - Favicon does not exists.
  • favicon.redirect- Favicon request was redirected instead of just serving.
  • compress.images - GZIP was detected on any images on the page.
  • whitespace - The HTML returned from server was not minified and contained whitespace that could have saved some space.
  • gzip.internal - Returned if any CSS or JS assets on the same domain are not gzipped.
  • gzip.external - Returned if any CSS or JS assets on a third-party domain are not gzipped.
  • h2 - HTTP2 is not supported on server.
  • h2.blank - Blank response from HTTP2 server
  • h2.push - HTTP2 Server Push could be used on blocking resources for the page.
  • minify - Resources returned were not minified.
  • minify.empty - Resource was empty after content was minified, meaning the request could probably just be removed.
  • pagespeed.slow - Initial response took more than 3 seconds seconds to render.
  • pagespeed.warn - Initial response took more than 1 second to render.
  • redirect.count - No more than 2 initial redirects should occur.
  • redirect.clientside - Uncacheable client-side redirect using Javascript which caused the browser to load a entire new page
  • vary - Vary header was not configured on the responses of resources.

Running

The rules are checked everytime a url is run through Passmarked or our API. To run using the hosted system head to passmarked.com or our Terminal Client use:

npm install -g passmarked
passmarked --filter=network example.com

The hosted version allows free runs from our homepage and the option to register a site to check in its entirety. Using the Passmarked npm module (or directly via the API) integrations are also possible to get running reports with all the rules in a matter of seconds.

Running Locally

All rules can be run locally using our main integration library. This requires installing the package and any dependencies that the code might have such as a specific version of OpenSSL, see #dependencies

First ensure passmarked is installed:

npm install passmarked
npm install @passmarked/network

After which the rules will be runnable using promises:

passmarked.createRunner(
  require('@passmarked/network'), // this package
  require('@passmarked/ssl'), // to test SSL
  require('@passmarked/inspect') // to test network performance
).run({
  url: 'http://example.com',
  body: 'body of page here',
  har: {log: {entries: []}}
}).then(function(payload) {
  if (payload.hasRule('secure')) {
    console.log('better check that ...');
  }
  var rules = payload.getRules();
  for (var rule in rules) {
    console.log('*', rules[rule].getMessage());
  }
}).catch(console.error.bind(console));

Alternatively, callbacks are also available:

passmarked.createRunner(
  require('@passmarked/network'),
  require('@passmarked/ssl'),
  require('@passmarked/inspect')
).run({
  url: 'http://example.com',
  body: 'body of page here',
  har: {log: {entries: []}}
}, function(err, payload) {
  if (payload.hasRule('secure')) {
    console.log("better check that ...");
  }
  var rules = payload.getRules();
  for (var rule in rules) {
    console.log('*', rules[rule].getMessage());
  }
});

Dependencies

The module expects a updated version of OpenSSL, at the time of writing openssl-1.0.2h. The module expects the newest compiled excutable to present at /usr/local/ssl/bin/openssl.

# install our essentials to build openssl
apt-get install -y build-essential

# upgrade to a much newer and specific version of ssl
wget -O /tmp/openssl-1.0.2h.tar.gz https://www.openssl.org/source/openssl-1.0.2h.tar.gz
cd /tmp/ && tar -xf /tmp/openssl-1.0.2h.tar.gz
rm /tmp/openssl-1.0.2h.tar.gz
cd /tmp/openssl-1.0.2h && ./config
cd /tmp/openssl-1.0.2h && make depend
cd /tmp/openssl-1.0.2h && make
cd /tmp/openssl-1.0.2h && make install
rm -R /tmp/openssl-1.0.2h

The module also expects to see timeout from coreutils present in some form, this defaults to gtimeout on MacOS which can be installed using:

brew install coreutils

Rules

Rules represent checks that occur in this module, all of these rules have a UID which can be used to check for specific rules. For the structure and more details see the Wiki page on Rules.

Rules also include a type which could be critical, error, warning or notice giving a better view on the importance of the rule.

Contributing

git clone [email protected]:passmarked/network.git
npm install
npm test

Pull requests have a prerequisite of passing tests. If your contribution is accepted, it will be merged into develop (and then master after staging tests by the team) which will then be deployed live to passmarked.com and on NPM for everyone to download and test.
