Performance Optimization for Reading 3000 JS Files on Startup

[sarahlydia9868]

Hi team,

I'm working on a project that involves loading around 3000 JavaScript files at startup using QuickJS-NG. While the engine works well overall, the startup time has become a major bottleneck due to the sheer number of files being read and parsed.

I'm wondering if there are any recommended strategies or features in QuickJS-NG that could help speed up the reading and initialization of large numbers of JS files. Some ideas I’ve considered:

Precompiling scripts to bytecode ahead of time

Bundling or merging files to reduce I/O overhead

Using lazy loading or deferred execution

Parallelizing file reads (if supported)

Has anyone faced similar challenges or found effective solutions for large-scale JS file loading with QuickJS-NG?

Thanks in advance for any insights!

For my JS engine I don't quite have 3k files but a good amount, and I bundle them with esbuild and pre compile them. Works well!
