NPM hangs and gets stuck on publish/pack

Question

npm publish and npm pack were both stuck for me. On the prepack step it would run indefinitely maxing out the CPU.

Answer 1

I got the same issue. The reason was that I had larges files of data (decades of Go) making packaging so slow that it looked to be stucked.

Answer 2

For me it was the registry that had issues. Make sure that everything is green at https://status.npmjs.org/!
