# @passmarked/css

![NPM](https://img.shields.io/npm/dt/@passmarked/css.svg) [![Build Status](https://travis-ci.org/passmarked/css.svg)](https://travis-ci.org/passmarked/css)

[Passmarked](http://passmarked.com?source=github&repo=css) 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](http://npmjs.org/package/passmarked) 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](http://passmarked.com?source=github&repo=css) can be voted on importance and are [open-sourced](http://github.com/passmarked/suite), to encourage community involvement in fixing and adding new rules. We are building the living Web Standard and love any [contributions](#contributing).

## Synopsis

The rules checked in this module are generated by a linter that is being used. At present we don't have any specific tests to list. We've taken note to disable rules that do not apply on minified CSS for us and kept the rules that are important for compatible and predictable styles active.

All generated rules are grouped and categorised over at [passmarked.com/library/css](https://passmarked.com/library/css?source=github&repo=css) which is the best option to view the list of rules we have generated so far by looking at pages. The UID's of those rules can then be used as with any other rule to check for specific conditions if required.

## 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](http://passmarked.com?source=github&repo=css) or our [Terminal Client](http://npmjs.org/package/passmarked) use:

```bash
npm install -g passmarked
passmarked --filter=css 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](#dependencies)

First ensure `passmarked` is installed:

```bash
npm install passmarked
npm install @passmarked/css
```

After which the rules will be runnable using promises:

```css
passmarked.createRunner(
  require('@passmarked/css'), // 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:

```css
passmarked.createRunner(
  require('@passmarked/css'),
  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](https://github.com/passmarked/passmarked/wiki) page on [Rules](https://github.com/passmarked/passmarked/wiki/Create).

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

## Contributing

```bash
git clone git@github.com:passmarked/css.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](http://passmarked.com?source=github&repo=css) and on NPM for everyone to download and test.
