## Development
### Backend
Pre-requisites: `pipenv`, or whichever venv manager you prefer
```sh
# Install all dependencies. `pipenv` was used previously:
pipenv --python 3.11
pipenv install
pipenv shell
# Start dev server
pipenv shell
fastapi dev app/main.py
# Start posting data to the tracing endpoint:
traceroute git.rauhala.info -q1 | http POST localhost:8000/trace/MYHOSTNAME
```
### Frontend
Pre-requisites: `nvm`, `tsc` / `typescript`
```sh
# Install latest npm version with node version manager:
nvm install 22
# Install project packages:
npm install
# Regular usage, activate project node version & start TS compiler in watch mode:
nvm use
tsc -w
```
## URLs of interest
