Worked on the launchdarkly/observability-sdk repository to improve security and dependency hygiene by upgrading the @graphql-codegen/cli package from version 5.x to 6.3.1. Focused on reducing production vulnerabilities, the developer moved code generation tooling and lodash from runtime to development dependencies, ensuring lodash was no longer present in production paths. Regenerated the yarn.lock file and aligned related packages, including @graphql-codegen and Babel dependencies, across multiple modules. Verified the changes by running code generation for observability-node, confirming no impact on production code. Demonstrated skills in dependency management, npm auditing, and JSON, with a disciplined approach to secure package upgrades.
