Aural Training

This is the source code for the aural.training website.

Prerequistes

1. lein must be installed
2. npm must be installed
3. rollup must be installed
4. less must be installed

npm install --global rollup

Develop

Run the clojure server

lein repl
aural-training.dev=> (dev-init!)

Watch for typescript changes

rollup -c -w

Open in browser

http://localhost:3000

Connect to the websocket with wscat

wscat --connect ws://localhost:3000/ws

LESS

LESS is being used for the css. The following commands will compile and watch

npm run watch

Roadmap

1. MVP - note memorization lesson
2. Public Release to https://aural.training

Notes

https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/stroke-opacity might have some interesting ideas for making the pluck strings circles more interesting

Pipeline operator

We investigated using the pipeline operator (|>) and stash some code locally for this. see: https://babeljs.io/docs/en/babel-plugin-proposal-pipeline-operator

Problems:

1. We will lose Typescript warnings in the rollup compiliation step.
2. The lsp linter does not like parsing |>
3. It's not a R-style pipe or clojure thread, it needs a "topic token", like ^^

React

React (v18, latest) is not in a place that can be easily used with rollup/tsc. It's a configuration nightmare with no straight forward answer.

Syncing DB

The websocket on the backend needs more work. The frontend dexie db sync seems to delay connecting, or not connect at all.

Freelize Problems

We will need to use something else to process notes. We will need something that uses Fast Fourier Transform (FFT)
