We couldn't even stand 6 months let alone a year. Broken pack depts make it hard to CI, poor performance, memory leaks, huge docker base images due to deps, lots of single cpu only tasks that were too hard to scale out, an ugly language compared to ruby or Python and on top of all that how poor the package management with NPM has been. We've just ditched it and gone back to Python/Django/flask and ruby for the ops tooling.
