  • Added Jest and started adding tests with React Testing Library. Previously the project only used E2E tests with Selenium and Playwright, but we needed something that run faster during local development.
  • Added Storybook to the project to start documenting the new component library. Gradually added components to it, with props documentation and examples.
  • Created a throughout performance report of the app using Lighthouse and webpack-bundle-analyzer, which included set of suggested follow up actions to solve some of the issues (like implementing lazy loading, combining multiple GraphQL queries into a single one, and more).

  • Started the conversation on adding hot reload to improve the developer experience, which was eventually added by a team mate.
