Rules related to checking if the Javascript produced by the page does not throw any errors or show messages in the log

@passmarked/javascript

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:

  • alert - The page opened a alert while loading without user interaction, each occurrence is listed with the message presented.
  • log - Page had console output, which could indicate that debugging was not removed amongst others. Keeping the console clean is the big priority here.
  • error - Page encountered a Javascript error, returned is the message shown along with the file and line numbers.

The module requires the console,alerts and errors in the payload given. On Passmarked this is generated and passed.

The module expects the following properties:

{
 
  console:  [
 
    {
 
      created:  <timestamp when this happened>,
      line:     <line number>,
      message:  <message produced>,
      file:     <file of error>,
      type:     'log'
 
    },
    {
 
      created:  <timestamp when this happened>,
      message:  <Message of error>
      type:     'error'
 
    }
 
  ],
  alerts:   [
 
    { 
 
      created: <timestamp when this happened>,
      message: <message of alert> 
 
    }
 
  ]
 
}

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=javascript 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/javascript

After which the rules will be runnable using promises:

passmarked.createRunner(
  require('@passmarked/javascript'), // this package 
  require('@passmarked/ssl'), // to test SSL 
  require('@passmarked/network') // 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/javascript'),
  require('@passmarked/ssl'),
  require('@passmarked/network')
).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

This module does not need any specific external services or packages. This section will be updated if that ever changes with detailed setup steps/links.

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 git@github.com:passmarked/javascript.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.
