What does it mean You are running the esm-bundler build of vue-i18n?

Question

Vue.js

Warning code

You are running the esm-bundler build of vue-i18n. It is recommended to configure your bundler to explicitly replace feature flag globals with boolean literals to get proper tree-shaking in the final bundle.

How exactly do I need to set up the bundler... right...
