Error: too many open files in system about angular-bazel-example HOT 2 CLOSED

This should be fixed by the fine-grained npm dependencies:
https://github.com/bazelbuild/rules_nodejs#fine-grained-npm-package-dependencies

Another option under mac is to turn off the sandboxing
--genrule_strategy=standalone

(The root cause is that for each process Bazel starts, it makes an OS level sandbox where the inputs are linked, and that consumes filehandles. You either need fewer files as inputs, or disable the sandboxing feature, though the latter can mask hermeticity bugs.)

Npm fine grained deps is merged into angular-bazel-example so the number of files that need to be watched by iBazel is now much less. Only npm packages that are needed are now included as action inputs instead of all packages under node_modules.
