Graphql Sequelize Versions Save

Add missing files for previous release.

sequelize@6, graphql@16, [email protected] support via https://github.com/mickhansen/graphql-sequelize/pull/715 by @intellix

• added DateType [#621]
• typeMapper / attributeFields now converts Sequelize.DATE into DateType (used to be String) [#621]

relay.createConnection: the after callback is now always called, regardless of edges being requested or not

Fixes regressions introduced in v7.0.0

• Added support for having target in resolver/relay.sequelizeConnection being a thunk/callback
• Removed the default generated orderBy enum on connections

• dataloader-sequelize is no longer directly used by graphql-sequelize
• graphql-sequelize will now always generate N+1 queries unless

dataloader-sequelize has been removed to allow users to make their own decisions regarding batching and to avoid automatically polluting the sequelize object.

For improved performance and less database load (in terms of query count) we suggest implementing createContext from https://github.com/mickhansen/dataloader-sequelize

Internal JSON type renamed from JSON to SequelizeJSON and now exported as a reusable type:

https://github.com/mickhansen/graphql-sequelize/pull/403

resolver no longer adds context to findOptions by default as this can lead to memory leaks when Sequelize does deep cloning.

This major release changes the general philosophy of the project to rely on batching rather than includes. Almost all use cases will experience great performance improvements. There is a minor performance degradation in cases where the query is only one level deep with a single belongsTo relation.

• Removed prefetching/includes in favor of https://github.com/mickhansen/dataloader-sequelize
• Removed filterAttributes (use filter in before)
• Removed defaultAttributes
• Removed simpleAST from resolver info (use simpleAST user-side now)
