Migrating

Migrating from v4.0 to v4.1

GraphQLite follows Semantic Versioning. GraphQLite 4.1 is backward compatible with GraphQLite 4.0. See semantic versioning for more details.

There is one exception though: the ecodev/graphql-upload package (used to get support for file uploads in GraphQL input types) is now a "recommended" dependency only. If you are using GraphQL file uploads, you need to add ecodev/graphql-upload to your composer.json by running this command:

$ composer require ecodev/graphql-upload

Migrating from v3.0 to v4.0

If you are a "regular" GraphQLite user, migration to v4 should be straightforward:

• Annotations are mostly untouched. The only annotation that is changed is the @SourceField annotation.
  • Check your code for every places where you use the @SourceField annotation:
  • The "id" attribute has been remove (@SourceField(id=true)). Instead, use @SourceField(outputType="ID")
  • The "logged", "right" and "failWith" attributes have been removed (@SourceField(logged=true)). Instead, use the annotations attribute with the same annotations you use for the @Field annotation: @SourceField(annotations={@Logged, @FailWith(null)})
  • If you use magic property and were creating a getter for every magic property (to put a @Field annotation on it), you can now replace this getter with a @MagicField annotation.
• In GraphQLite v3, the default was to hide a field from the schema if a user has no access to it. In GraphQLite v4, the default is to still show this field, but to throw an error if the user makes a query on it (this way, the schema is the same for all users). If you want the old mode, use the new @HideIfUnauthorized annotation
• If you are using the Symfony bundle, the Laravel package or the Universal module, you must also upgrade those to 4.0. These package will take care of the wiring for you. Apart for upgrading the packages, you have nothing to do.
• If you are relying on the SchemaFactory to bootstrap GraphQLite, you have nothing to do.

On the other hand, if you are a power user and if you are wiring GraphQLite services yourself (without using the SchemaFactory) or if you implemented custom "TypeMappers", you will need to adapt your code:

• The FieldsBuilderFactory is gone. Directly instantiate FieldsBuilder in v4.
• The CompositeTypeMapper class has no more constructor arguments. Use the addTypeMapper method to register type mappers in it.
• The FieldsBuilder now accept an extra argument: the RootTypeMapper that you need to instantiate accordingly. Take a look at the SchemaFactory class for an example of proper configuration.
• The HydratorInterface and all implementations are gone. When returning an input object from a TypeMapper, the object must now implement the ResolvableMutableInputInterface (an input object type that contains its own resolver)

Note: we strongly recommend to use the Symfony bundle, the Laravel package, the Universal module or the SchemaManager to bootstrap GraphQLite. Wiring directly GraphQLite classes (like the FieldsBuilder) into your container is not recommended, as the signature of the constructor of those classes may vary from one minor release to another. Use the SchemaManager instead.
