It was kind of spooky to see people ending up with well-architected code without. In the third part of this series well expand the complexity of our system a bit. By now you have probably heard about Elm the statically typed immutable Haskell inspired polite and helpful functional reactive language for the web.
It will be worth it. A simple Todo tracker is one of the most popular entry-level projects to get started with a new language or technology. Richard explains how this project will progress from a single webpage to knowledge of how to fix bugs and to modify and maintain a real-world Elm codebase.
Well build a simple Todo list application and see how we can combine many different elements and how we pass information around. The one that worked for me is OBDSim. One of the aims of TodoMVC is to enable a fair comparison between several frameworks by providing implementations of the same application.
The first graphql query you will write will be to fetch personal todos. You will need to load the todo data from the database which belongs to the logged in user. It is an open source project available for different platforms.
We will construct a GraphQL Mutation to update a private todo and integrate it with the elm app. Its extremely FAST too. The MVU ElmElmish architecture.

Lets import the types utility functions generated by elm-graphql into our app and construct a GraphQL query. Elmish Micro Front-end Framework TDD walkthroughtutorial. Well see how.
This architecture seems to emerge naturally in Elm. Hold on do you really have a car close enough to your development environment. It is a purely functional front-end architecture commonly used in Elm a strongly typed pure functional language that compiles to JavaScript.
In part 2 of the series well get into more depth with Elms architecture. It consistently performs better than React Ember Angular and others in the TODO MVC performance tests.
