A vision for data interchange in Elm

How do you send information between clients and servers? What format should that information be in? What happens when the server changes the format, but the client has not been updated yet? What happens when the server changes the format, but the database cannot be updated?

These are difficult questions. It is not just about picking a format, but rather picking a format that can evolve as your application evolves.

Literature Review

By now there are many approaches to communicating between client and server. These approaches tend to be known within specific companies and language communities, but the techniques do not cross borders. I will outline JSON, ProtoBuf, and GraphQL here so we can learn from them all.

Should be work with 0.18

Destructuring(or pattern matching) is a way used to extract data from a data structure(tuple, list, record) that mirros the construction. Compare to other languages, Elm support much less destructuring but let's see what it got !

Tuple

myTuple = ("A", "B", "C")
myNestedTuple = ("A", "B", "C", ("X", "Y", "Z"))

#You should do all your LAMP development in a Virtual Machine

##Here's Why:

Many of us develop on Macintoshes. There are many reasons for this, but one of them is that it's based on a Unix platform of some sort. This allows us to run common server software such as Apache, Ruby, Python and Nodejs on our Macs.

Our computers become powerful develoment machines similar to the servers our apps will eventually live on.

Sometime we start our computer only to find Apache won't start, or MySQL can't create a PID file, or we've updated to Mountain Lion and Apache needs to be reconfigured. Death!
