This module is developed and maintained by Kewei Chen.
The goal of this module is to detect user defined SEO defects in a html text. Example of how to utilize this module to create rules and detect SEO defects is written in test.js. For quick start, run "npm test" to see the result and refer to "test.js" to help coding. Following is classes provide in this module.
Methods:
- withoutAttribute(attr_name, attr_value)
- anyThisTag()
- withoutTag(tag_rule)
- amountMoreThan(number_of_the_tag)
All the methods above provide fluent interface. That is, the returned value of any these methods is the object reference itself. Hence you can chain these methods in a more readable way.
Usage:
Create a rule to detect any <img> without alt attribute:
rule = createTagRule('img').anyThisTag().withoutAttribute('alt')
In <head>, check if <meta name='description> cannot be found:
rule = createTagRule('head').withoutTag(createTagRule(meta).withoutAttribute('name', 'description'))
Methods:
- addRule(rule)
- addRules(rule_list)
- detectByFile(file_name, output_stream)
- detectByStream(input_stream, outputstream)
- createTagRule(tag_name)
- createSEODefectsDetector()
Both of above functions do nothing but wrap the behavior of creating an object of the corresponding class. It just makes the code more readable.
