# After updating to build_bazel_rules_nodejs 0.27.0+, rollup has been updated to v1.3.1
# which tree shakes @__PURE__ annotations by default. We turn this feature off
# for ng_package as Angular bundles contain these annotations and there are
# test failures if they are removed. See comments in
# https://github.com/angular/angular/pull/29210 for more information.

# `rollup-plugin-sourcemaps`, which will require us to use rollup.config.js file instead
