This repo simulates multiple ways how to block and not block (for a long time) event loop by "heavy" processing.

Just to try to load data from the endpoint once:

curl http://localhost:3000/process-data-async -o ./tmp/as.json
curl http://localhost:3000/process-data-stream -o ./tmp/st.json
curl http://localhost:3000/process-data-immediate -o ./tmp/i.json
curl http://localhost:3000/process-data-chunks -o ./tmp/c.json
curl http://localhost:3000/process-data-worker -o ./tmp/w.json
