For small codebases it should be fine. For mid-large / anything serious, I'd still compile for now. We have a decent amt of perf work to do
What's the impact on static analysis based tree shaking? Doesn't it make it harder to figure out which modules are needed ahead of time?
Yes. Short term: flattened dependencies + careful use of import() + preload needed for acceptable loading story. Lots tooling can help wire.
Has anyone crafted a faster than bundling demo yet?
Bundling has the advantage of benefitting more from minification and gzip, vs lots of tiny files w/ modules. Hard to make up for that atm.
Strong agree. Chrome shipping more perf footguns feels questionable to me. I would much prefer it going through the origin trial process
After 3 benchmarks, we know 'full' ESM has IPC, compile, Blink layer costs, modules fetched at lower prio by default. Usage will req care.
I'll push for more of our data on this to be published for awareness. Agree with Sergio's position here otherwise.
The low-pri request issue seems pretty bad. Is there a crbug for it?
Addressing this _might_ already be part of on-going work into the module fetching algo. Tagged you into a comment w/Kouhei and @KenjiBaheux
