Mosaico is a JavaScript library (or maybe a single page application) supporting the editing of email templates. The great thing is that Mosaico itself does not define what you can edit or what styles you can change: this is defined by the template. This makes Mosaico very flexible.
At this time we provide a single "production ready" template to illustrate some best practice examples: more templates will come soon! Have a look at Template Language and get in touch with us if you want to make your email html template "Mosaico ready".
On https://mosaico.io you can see a live demo of Mosaico: the live deploy has a custom backend (you don't see it) and some customization (custom Moxiemanager integration for image editing, customized onboarding slideshow, contextual menu, and some other small bits), but 95% of what you see is provided by this opensource library. You will also see a second working template there (versafluid) that is not part of the opensource distribution.

You need NodeJS v6.0 or higher + ImageMagick
Download/install the dependencies (run again if you get an error, as it probably is a race issues in npm)
npm install
if you don't have it, install grunt-cli globally
npm install -g grunt-cli
compile and run a local webserver (http://127.0.0.1:9006) with incremental build and livereload
grunt
IMPORTANT in order to use image uploading/processing feature in Node you need imageMagick installed in your environment. e.g. running "convert" and "identify" on the command line should output imageMagick command line help (if you are on Windows and install imageMagick 7.x then make sure to install "legacy utilities").
NOTE we have reports that default Ubuntu node package have issues with building Mosaico via Grunt. If you see a Fatal error: watch ENOSPC then have a look at voidlabs/mosaico#82
We bundle a Dockerfile based on Alpine linux and another based on Centos 7 to test mosaico with no need to install dependencies.
docker build -t mosaico/mosaico .
docker run -p 9006:9006 mosaico/mosaico
then open a browser to point to the port 9006 of your docker machine IP.
First you have to build it using grunt, then you MUST read Serving Mosaico.
MailTrain is a full featured newsletter web application written in Node and support email editing via Mosaico since their 1.23.0 release.
GoodEnough's Mosaico born as a Mosaico fork, now have become a full web application product built around Mosaico editing targeting agencies.
