lib: include ESM loader in the built-in snapshot by joyeecheung · Pull Request #61769 · nodejs/node

joyeecheung · 2026-02-11T04:52:49Z

Benchmark number from an ARM64 Linux machine: empty/minimal CJS startup is now slightly slower in worker but other metrics get a slight boost (because they all incur ESM loader initialization). In reality ESM loading is likely to happen at some point in the lifetime of an application especially with the growing adoption of ESM and require(esm), so real-world applications that are more than just an empty script should get a bit of speed up from being able to just deserialize the ESM loader instead of initializing it from scrach.

One question for my understanding: I noticed defaultResolve and defaultLoadSync are still lazy-loaded with ??= while translators was moved to pre-loading. Is this because:

These are only used when there are no custom loader hooks (less common path)?
Their dependencies are heavier and would hurt startup more?
Or is this something that could be optimized similarly in the future?

Just curious about the design rationale

I noticed defaultResolve and defaultLoadSync are still lazy-loaded with ??= while translators was moved to pre-loading.

Did you mean in esm/loader.js? I believe I've removed them. If not could you leave a pointer to the line where it still remains? Happy to update them in this PR.

My code base in my local was very old, nvm. Thank you!

Looks like this got broken by #61665 which added filtering of internal frames but the regex couldn't understand async frames. Updated the regex to handle async frames. cc @legendecas

Looks like the new regex didn't work with test runner outputs somehow. Updated. Can you take a look again? @legendecas Thanks!
