yarn-1.3.2-with-ignore-fix.js

Kibana ships with a vendored version of Yarn, which is used to install dependencies when preparing the production build of Kibana.

The currently vendored version of Yarn contains the bugfix in https://github.com/yarnpkg/yarn/pull/5059, which handles optional dependencies.

To build a new Yarn bundle, check out that pull request and run:

yarn build-bundle

This will create the file artifacts/yarn-1.3.2.js, which can be renamed and moved to this folder.
