Mosaico - Responsive Email Template Editor

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.

Developer Notes

$3

You need NodeJS v8.0 or higher + NPM 8.3 (because of "overrides" support in package.json you need npm 8.3 if you want to change/upgrade dependencies, but it should work with older npm, too, if you rely on package-lock.json)

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
`
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 https://github.com/voidlabs/mosaico/issues/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.
