Uncaught Error: Module did not self-register

[Somebi]

Getting this error... removing node_modules or npm rebuild is not helping.
This error is thrown when i'm using threads (workers)

Node version?

node addons have to explicitly support workers for them to work in that scenario. The main reason for this is that some addons can have global state which would not work for multiple threads.

But calling require not in the global scope, works without errors. Problem exists only when define module in the top most place (i.e. global scope) вс, 3 мар. 2019 г., 10:13 Denis Abramov <somebi@gmail.com>:

Can you show an example of each?

I have meet same issue when tried to require xxhash in thread (node v12.8.1, pull/30 applied). But was able to solve it by changing src/hash.cc:

11c11,13
< NODE_MODULE(addon, Init);
---
> NODE_MODULE_INIT() {
>   Init(exports);
> }

and re-build binary: cd build && make

Code to reproduce the issue:

(async () => {
  const { job, start, stop } = require('microjob');
  var XXHash = require('xxhash')
  await start();
  await job(() => {
      var XXHash = require('xxhash')
  })
})()
