esbuild

Simplest possible usage of esbuild: https://gist.github.com/llimllib/6730d9d01011e4031b2f1190740d9ad4

I rewrote it as a blog entry here: https://billmill.org/bundle_d3_with_esbuild.html

Command to build a library composed of typescript files into a single library importable as an IIFE, with a given name. In this case, I'm building chessops into a javascript library that can be imported, giving a global name of chessops to the imports:

esbuild --bundle --outdir=build --global-name=chessops ./src/index.js
