Gatsby Days, originally planned as a virtual event, was transformed into a content series by the Gatsby team to respect the Black Lives Matter movement, allowing for the sharing of insights from scheduled speakers at a more suitable time. The series includes presentations like Trevor Blades' on Gatsby's plugin ecosystem, highlighting tools such as gatsby-plugin-ngrok-tunneling and the new gatsby-source-wordpress-experimental plugin, which enhance the local development experience by facilitating remote collaboration and providing new functionalities. Trevor Blades, a Senior Software Engineer at Apollo GraphQL, focuses on creating content to support developers using GraphQL, with all sites built using Gatsby due to its superior local development experience. His presentation and related resources, including slides and live coding sessions, are accessible online for further learning and engagement.
