Release Notes

cometkim/gatsby-plugin-typegen (gatsby-plugin-typegen)

v3.1.0

Compare Source

• Added Gatsby v5 to the peerDependencies range.
• Deprecated commentDescriptions option in emitSchema in favor of GraphQL.js v16.

v3.0.0

• Added support for GatsbyImageData scalar. (See gatsbyjs/gatsby#35683)
• [BREAKING CHANGE] nullable fields are typed as T | null, instead of T | undefined (which was inaccurate).
• The output is now stable, no more dev-only fields, no more randomly-sorted definitions.
• autoFix option is renamed to autofix. Previous option will be removed in v4.
• emitPluginDocuments option is renamed to emitPluginDocument. Previous option will be removed in v4.
• Fixed bunch of bugs (#​138).
• Introduced a very predictable & debuggable scheduler built on top of XState.

However, Gatsby now has builtin feature for typegen from GraphQL queries!
