flash-qc

App to create flashcards for anything (cualquier cosa)

Projects

• docker-compose-poc/: Docker Compose multi-service architecture demonstration with Nginx, Astro frontend, Rust backend, and PostgreSQL
• diesel-poc/: Diesel ORM exploration (Rust)

Architectural Discussion

Traditional Front-Back system. Back: Lambdas (we could have lots of users before even being close to hitting the free tier limits). Storing flashcards in S3, same format as section 1.

Tech: - Front: Astro - Back: Rust (Rocket, Diesel)

Monetization

• We could give users a given amount of free flashcards per day and charge after that. Of course, free at the beginning.

Plugins

• Inyectable javascript with a defined aplication interface.

Rust tooling

• Diesel as ORM: Tested. It does require keeping the migrations manually made with SQL, but otherwise seems to work very well.
• Rocket for HTTP engine: Tested.

Interesting ideas

• Suggest changes to card author, using git as a backend for this, and make an ui to hide it.
• Gamify: Interesting, it can be done at the card level, which allows people to modify their decks without losing the competition posibilities.
  • Deck "Leaderboards" ala Duolingo would be nice-to-have
• Automatic definition for language learning use case (by fetching from dictionary and/or LLM)
• Import decks from Anki

Weak Anki points

• Python as plugin language is not great for web
• Interface is too highly convoluted and complex.
• Phone apps dont have plugins
  • The experience in android and iOS is very different
  • Offer different features

Setup

First time ever

Running the pre-commit hook setup

Make the setup script executable and run it (this will install the project's pre-commit hooks):

chmod +x ./setup.sh && ./setup.sh

Assuming you have rust

sudo apt install libpq-dev
sudo apt install libsqlite3-dev
cargo build
cargo bininstall diesel_cli
diesel setup

On every start

diesel migration run

Adding new Migrations

diesel migration generate <migration_name>

This will create a new folder in migrations/ with up.sql and down.sql files: You have to fill those yourself. For now there will be NO alter commands, only create and drop.
