Cross Mail Warrior

Small Class for inlined html email template cross-client responsibility.

problem

The most email mobile client apps automatically remove all className selectors from your template and responsibility won't work

solution

After inlining all basic styles by packages like 'inline-css' you need to set all styles with breakpoints inside <style></style> tag and call new instance of Cross Mail Warrior to replace all className selectors into any attributes. Also you can specify a prefix for new attributes value.

usage

Firstly, install the package

$ npm install cross-mail-warroir --save-dev

Import it to your script, which compile your email template

const CrossMailWarrior = require('cross-mail-warrior');

Call it for your source/dest folders

new CrossMailWarrior({
    /*required. Array of strings. Specify which attribute(s) you want to replace from classNames*/
	cloneToAttrs: ['data-lang', 'data-etc'],
	/*not required. String. Prefix of attribule value. 
	Default: ""
	Exapmle: <div class='block'> will replace to <div data-attr='x-block'>*/
	valuePrefix: 'x-',
	/*not required. Boolean. Directive, which found end of css rule and sets the important to reinherit inline styles*/
	setImportants: true,
	/*not required.
	Defaults:
	path.source: path.join(__dirname, 'source')
	path.dest: path.join(__dirname, 'dest')*/
	paths: {
	    source: "path/to/source",
	    dest: 'path/to/dest'
	}
})

notes

• Do not minify your code into style tag. You need to \n for !important automatical sets.
