About BigInt usage

[Catutigernos]

Hi,
I am developing a module has some function get 64 bit integer as parameter, javascript side I sent as bigint, but native side I can not get the parameter with NAPI. I check lib, and BigInt is guarded in native library, and I check parameter type in native side, variable type is 9, and I cannot find the type in napi_valuetype enum. How could I get the 64 bit number? If I can't when BigInt will be published?

Thanks in advance.

Hi @Catutigernos,
if you want to use BigInt you need to define NAPI_EXPERIMENTAL macro in your code because until N-API version 5 BigInt is an experimental feature.
We are working on a new version here #689 where we support N-API version 6 that includes BigInt as stable API.

Hi @NickNaso,
Thanks for your response. I will try, but I am not sure about its reliability, because it can be unstable. Is there any estimated release date for N-API 6?

It's in 10.x and 14.x (see https://github.com/nodejs/node/blob/master/doc/api/n-api.md for the version where it was added) I think just waiting on the next SemVer minor of 12.x for it to be there.

@Catutigernos N-API 6 should now be available across all LTS versions. Please re-open this issue and/or file a new one if you still have questions!
