ElixirTodoApp

This is my first full stack application using the Phoenix Framework. No tutorials, no YouTube follow alongs. Just me figuring out routes, functions, pattern matching, forms, error handling and how to read and debug the compiler's error messages (this is a big one for me). The application is deployed on Heroku: https://elixir-todo-list.herokuapp.com/

There are 2 templates: the homepage and a page to edit a todo item

Things to improve

Error handling

At the moment I'm just returning a generic error message when the changeset returns an error. It would be better to display the error returned from the changeset to give more useful information to the user.

Styling

The purpose of this todo list was to build my confidence in creating a full stack application with the Phoenix framework - focusing on transforming data, understanding changesets, how to display data in the templates, etc. The styling is an afterthought in this. I know it's very ugly so it's listed as a low priority improvement to make.

To start your Phoenix server:

• Run $ git clone git@github.com:zahradeenie/elixir_todo_app.git
• Run $ cd elixir_todo_app
• Install dependencies with mix deps.get
• Build the docker database container with docker-compose up -d
• Create and migrate your database with mix ecto.setup
• Install Node.js dependencies with npm install inside the assets directory
• Start Phoenix endpoint with iex -S mix phx.server

Now you can visit localhost:4000 from your browser.
