premailer.js Fixing code consistency issues Apr 25, 2016


A simple api wrapper for, a great tool for inlining css before you send an email.

node-premailer simplifies api integration by calling the Premailer API to inline css styles (and other options such as removing comments, classes and ids), then retrieving the generated html and text from their respective URLs before passing them to your callback.


  npm install premailer-api

Or from source:

  git clone git://
  cd node-premailer
  npm link


var premailer = require('premailer-api');

var emailTemplate = `
      <title>My Email</title>
      <style type="text/css">
        a { color: #336699; }
      Styles inlined with
      <a href="">Premailer</a> via
      <a href="">node-premailer</a>.

premailer.prepare({ html: emailTemplate }, function (err, email) {
  if (err) throw err;
