Getting started

I assume that docker is both installed and running. https://docs.docker.com/get-docker

1. Clone the repo
2. Please use Yarn as a package manager
3. Build the Docker containers
4. Access the app via Svelte http://localhost:5173/

git clone https://github.com/paulambanks/mp3-file-analyser.git
cd mp3-file-analyser

docker compose up

# API
Express Server is running on http://localhost:3000

# SVELTE FE
Svelte app is running on http://localhost:5173

Running tests

Access API codebase and run tests

cd apps/express-api
yarn test

Interacting with the API

1. Directly with the API (Curl) - with already existing sample or by passing a new filepath

curl -Ss -X POST http://localhost:3000/file-upload -F "file=@apps/express-api/fixtures/sample.mp3"

2. Front-End uploader

Successful upload:
