## Install dev server packages
docker run --rm -w /app -v $PWD:/app -u $(id -u):$(id -u) node npm install
## Start the dev server
docker run --rm --init -it -w /app -v $PWD:/app -p 8080:8080 node node dev-server.js
Visit `localhost:8080` to view.
## Run a test
You need chrome and chromedriver installed. The Dockerfile builds an image that does that. Then run the test with that image.
`--network host` gives the container internet access. Necessary if tests make outside requests.
docker run --rm -it -v $PWD:/usr/src/app --network host btroops node google_test
TODO add firefox and geckodriver
## Rough way to save the SVG map generated by JavaScript client-side
const XMLS = new XMLSerializer();
const svg_xmls = XMLS.serializeToString(svg);
let bl = new Blob([svg_xmls], {type: "text/html" });

a.href = URL.createObjectURL(bl);
a.download = "map.svg";
a.hidden = true;
document.body.appendChild(a);
a.innerHTML = "something random - nobody will see this, it doesn't matter what you put here";
a.click()
