All methods return a promise, the underlying promise library we use is Bluebird. Methods can be used seperately, or chained together using the .then method. If you're not familiar with promises, instead of using a callback, you chain a .then method to get the results.
Inlines css from embedded or external styles. It'll automatically remove any link or style tags unless one of the data attributes below are used. View test fixtures to see examples.
Arguments
file - String containing path to file
string - String of HTML
buffer - Buffer of HTML
HTML data attributes
There are two supported data attributes that you can apply to <style> or <link> tags that have special meaning:
data-embed
- use on <style> or <link> tags if you want styles to be embedded in the <head> of the final output. Does not inline css
data-embed-ignore
- use on <link> tags to preserve them in the <head>. Does not inline or embed css
Example:
emailBuilder.inlineCss('path/to/file.html')
.then(function(html){
console.log(html);
});Send tests to Litmus.
Arguments
html - String/Buffer of HTML
Example:
var fs = require('fs');
var file = fs.readFileSync('path/to/file.html');
emailBuilder.sendLitmusTest(file)

});Send email tests to yourself

</html>gulp test - Runs jshint and mocha tests
gulp inline - Inlines css from test/fixtures/input directory and creates the test/fixtures/output directory. Run if you add/update any fixtures in the test/fixtures/input directory.
If you're having issues with Litmus taking forever to load a test or the title of the test is showing up as "No Subject", it is most likely an issue with the Litmus API. You can check the Litmus status page to find out if their having any issues. If that's not the case, submit an issue and we'll look into further.
