Using bun here over esbuild as bun generates correct esm code which works. esbuild right now outputs a weird mixture bundles which fails with cryptic "stream cannot be required dynamically" node error messages. The performance speedup here is quit substantial: (tester using hyperfine with a mocked out parser (always returning emtpy results), result files are fetched from a github gist and pushed to some webhook testing site. e.g. ```sh hyperfine --runs 25 -i 'SCAN_NAME=nmap NAMESPACE=default node --enable-source-maps parser-wrapper.js https://gist.githubusercontent.com/J12934/6440478a5005dafdf52c1236c859eed0/raw/bc212dffbdaaf03cdf119b60b0c5211533677b36/scanme-nmap-org.xml hyperfine --runs 25 -i 'SCAN_NAME=nmap NAMESPACE=default node --enable-source-maps parser-wrapper.js https://gist.githubusercontent.com/J12934/6440478a5005dafdf52c1236c859eed0/raw/bc212dffbdaaf03cdf119b60b0c5211533677b36/scanme-nmap-org.xml https://webhook.site/... ``` Results: Regular: Time (mean ± σ): 467.0 ms ± 47.2 ms [User: 443.8 ms, System: 97.7 ms] Range (min … max): 443.2 ms … 692.0 ms 25 runs Bundled: Time (mean ± σ): 246.0 ms ± 16.3 ms [User: 176.6 ms, System: 16.9 ms] Range (min … max): 232.7 ms … 319.7 ms 25 runs So total runtime dropped from 443ms to 232ms, but even more significant system time dropped from ~100ms to ~20ms. So it should require a lot less cpu cycles and resources to execute 🥳 Signed-off-by: Jannik Hollenbach <[email protected]>
