Comparing bundled vs unbundled perf

How to Run

npm run build
npm run dev

Compare localhost:4000 and localhost:4000/bundled.html

Details

Running build generates:

• 5000 modules under src/esm
• 5 levels deep import chain, with each level importing 1k modules in parallel.
• Also generates src/esm/bundled.js
• You can change the total number of modules by running e.g. npm run build -- 3000

Running dev starts a Node.js http2 server with self-signed cert, with maxConcurrentStreams set to 1,000.
