Gatsby Plugins There are two ways to inject external data into a Gatsby website: 🛠 At build-time (GraphQL) * At runtime (React, fetch…) & /phacks

Gatsby Plugins 🛠 What kind of data are suitable for build time injection? Static data (e.g. blog posts) or weakly dynamic data (where one can wait ~1 minute for them to deploy to production, e.g. e-commerce catalog updates). & /phacks

What kind of data are suitable for runtime injection? Highly dynamic data (e.g. real-time notifications, data controlled by users). & /phacks
