Support save and load emails

[bwl21]

Even if the discussion on voidlabs/mosaico#50 did not come to an end, I open this issue to get support for storing/listing/retrieveing Newsletters (emails) by the mosaico-php-backend.

Yeah this is something we want to do also. Storing the emails in cookies is not portable. I'd much prefer to be able to store it in a database so it can be shared by multiple users and can be retrieved on multiple devices.

[bwl21]

Do you have an idea how to do this? Are you also using local storage for now?

[mherbold]

We are still using Mosaico's default cookies storage. I have not looked into rerouting this data into a database back end yet. I suspect it will require some modification of the Mosaico base code itself but I haven't taken a look yet.

Maybe it's not friendly, but you can do this without changes to Mosaico library: we use in production the same library and simply add our own "plugins" to deal with custom backend (salve, load, test).

localstorage is a plugin that can be replaced by calling a different initialization method.

When I click to download the HTML, it seems to goto a blank page at the dl/ folder. It would be nice if I could figure out how to pass it back to a textarea entry.

Ehi bago, can you post the plugin for save and load with backend? Thanks

[bago]

I cannot opensource that plugin, sorry.

In a workplace, I see no benefit to only providing localstorage as the method for saving. It would be much more useful to save emails to the backend.

I think we need to respect that Bago cannot open source his solution. So let us contribute something of our own.

First we need a specification of the interfaces, in particular of the server interface. I see the following usecases:

1. list available emails
2. open a particular email
3. create a new email
4. save a particular email
5. delete a particular email
6. rename a particujlar email
7. clone a particular email
