QuickJSContext had no callback with id error when newFunction was called many times about quickjs-emscripten HOT 4 CLOSED

The limitation is due to QuickJS internally having only a uint_16 for "magic" on each function we create. I recently merged an improvement to this, but I didn't release it: #94

from quickjs-emscripten.

With #94 released, you'll have a limit of 65535 functions. Beyond that you'll need to do indirection in user-space. Meaning, if you've created 65534 functions (limit - 1), you should create a function that takes a function ID as a JS Number value, and maps that to a host function by reading the number.

Thank you for reply.

I also got that idea and implemented it in quickjs-emscripten-sync.

reearth/quickjs-emscripten-sync#21

It calls newFunction only once and it saves all funcImpl to the map with a number. I will try it and confirm if it works in our environment.

Sounds good 😄
