Khaled Garbaya, a Contentful developer and Gatsby contributor, has created a 4-part video tutorial series aimed at helping users build a high-performance website using Gatsby and Contentful, which begins by converting Gatsby's starter example into a Contentful-powered site. The series covers various aspects of website production, including automated deployment with CircleCI and the integration of Contentful webhooks, serving as documentation for those interested in leveraging the combination of Gatsby and Contentful. This synergy is highlighted through Gatsby's component-based React integration and Contentful's content-as-components approach, which provides a seamless match for rendering content types across a website. Additionally, the series underscores the efficiency gained from Contentful's sync endpoint, which only processes changed entries, and Gatsby's use of GraphQL schemas for data querying. The video tutorials, available on YouTube, are complemented by accessible source code on GitHub and a ready-to-use Contentful + Gatsby blog starter repo for quick project initiation.
