esbuild - an extremely fast JavaScript bundler and minifier
esbuild [options] [entry points]
esbuild is a JavaScript bundler and minifier. It packages
up JavaScript and TypeScript code for distribution on the web.
Why build another JavaScript build tool? The current build tools
for the web are at least an order of magnitude slower than they should be.
It is hoped that this project serves as an “existence proof”
that JavaScript tooling can be much, much faster.
