I think it's worth sharing the progress of my lottie compiler here: github.com/cometkim/ulo... You can test it on the demo page, which now has a live output preview in the breakdown section.

wip: AOT compiler for Lottie animations. Compiles Lottie JSON files into an optimized JS code that runs standalone without additional player runtime. So 16K of JSON + 600K of player runtime are shrunk into a few K of a single JS file. Has anyone wanted this before?

Now we have... - All ReScript's runtime types - Stdlib with dts included - External types with validation - Opaque types to ts-style branding This already provides higher-quality output than the existing genType.
