ts tips

npx tsc --init creates the tsconfig.json

• What is npx?
• npx is an utility that either executes the command and if necessary, installs it prior to execution.

npm install @types/node --save-dev allowed me to use node modules, e.g. fs

• Looks like @types comes from DefinitelyTyped

How do I use other modules, e.g. XMLDocument and XMLSerializer (default Web APIs)?

• They are built into the browser runtime, and they don't work outside of the browser (e.g. in node.js)
• Consider using something like parse5 and xmlserializer
• this was not at all nice to use. Sadly the project in question lost its TS privileges and will be written in language that can handle SVG
