MI-AFP Homework Elm #01
Homework to practice Elm language and the basics of The Elm Architecture.
Scripts
Format elm code.
npm run format
Run tests for Part I.
npm run test
Run for Part II and open in browser.
npm run dev
Part I
The goal of this part is to practice the Elm language. There are several functions in the file src/Lib.elm
waiting for your implementation. Each function has a documentation comment with a description of what it is supposed to do. There are also unit tests for these functions in tests/LibTest.elm
which can help if something is unclear. You can run the tests using elm-test.
Most of the functions can be implemented using functions from elm/core
modules, such as List, Maybe, String or Dict. For the last one, indexOf
function, you should find appropriate package at package.elm-lang.org, install it and use it.
Part II
This part focuses on practising The Elm Architecture. The goal is to create a simple application that shows a story separated into three tabs (Introduction, Plot, Conclusion) with navigation between these tabs. When the app is opened, it should display the Introduction tab.
In the file src/Main.elm
, there is already a structure for the application prepared. Your goal is to
- Define necessary messages you need for your implementation,
- Define the type for the
Model
and implementinit
function to return initialModel
, - Implement the
update
function to update the model correctly according to the message, - Update
view
functions to- Dispatch messages when clicking on tabs,
- Display correct content based on active tab,
- Use
tabStyleActive
for active tab.
To open the application in the web browser, use elm reactor
then navigate to http://localhost:8000 and open the Main.elm
file.
