nodejs package deepspeech crashes (using node v16.0.0)

[solyarisoftware]

My program: deepSpeechTranscriptNative.js, part of a simple project DeepSpeechJs I made to use/test DeepSpeech nodejs bindings APIs, crashes when using latest nodejs version.
Below all details.

My configuration:

Notes:

• it seems to me that the issue is related to NodeJs version 16.0 and previouses?).

• I see that some updates has been done recently in the DeepSpeech project: https://github.com/mozilla/DeepSpeech/tree/master/native_client/javascript

• I have the same issue if I install deepspech package 0.10.0-alpha.3 instead of 0.9.3

• Maybe is the problem related to the deepspeech npm package (last update is 5 months ago) that has to be republished to include updates?

Thanks

@solyarisoftware There is no support for NodeJS v16 on the uploaded packages. Current packages on master have it but:

• GitHub Actions support only covers linux (amd64, armv7, aarch64), windows (amd64), macOS (amd64)
• Unfortunaly, unlike TaskCluster, we don't have the ability to access unauthenticated to the build artifacts
• There is no support for publishing new releases (Handle tag event on GitHub Actions #3606)
• TaskCluster infra has been completely decomissionned, so producing a 0.9.4 is impossible.

If you are willing to try and help, you are more than welcome. A good first item would be #3606 in your case.

Try and see if you can get deepspeech-tf.tgz or deepspeech-tflite.tgz from the last run: https://github.com/mozilla/DeepSpeech/actions/runs/793741932

@solyarisoftware The move to GitHub Actions was to make it easier for contributor to actually contribute, please read https://mozilla.github.io/deepspeech-playbook/CONTINUOUS_INTEGRATION.html

Hi @lissyx
I see your points / thanks for details.
I left the issue open. At least I propose to update this doc https://github.com/mozilla/DeepSpeech/blob/master/native_client/javascript/README.md with a reference to the current issue. Or I'd update the current public npm package version 0.9.3
