BEM Coverage

A tool to report the BEM coverage for your projects

You can use it both as cli or NodeJS module:

CLI:

npm install bem-coverage -g

You can run it as a command line tool by providing these arguments

bem-coverage --dir=/path/to/css/files --types=css,scss --output=/path/to/report/output/dir

...or run it in the current directory for css and sass extensions (the default types), like this:

cd /path/to/my/css
bem-coverage > bem-output.html

NodeJS:

// Output to folder
const bemCoverage = require('bem-coverage');
bemCoverage({
  directory: '/path/to/css/files',
  types: 'css,scss', //defaults
  output: '/path/to/report/output/dir'
});
 
//Supply callback function
bemCoverage({
  directory: '/path/to/css/files',
  types: 'css,scss'
}, function(data) {
    console.log(data.stats.BEM_RATIO, //outputs the percentage of BEM statements in your files
      data.stats.BEM, //outputs the number of BEM statements in your files
      data.report); //outputs the HTML report as a string
});
