Version: 0.16.x

Release Notes

What's new in Graphback#

This file contains changes and migration steps for the Graphback project. Please follow individual releases for more information.

0.16.2#

Bug Fixes#

  • Primary key with ID ScalarType and field name different to id isn't auto-incrementable. Fixed in #1997
  • Logical OR operator is not working correctly in MongoDB query builder. (#1963), fixed by (059a0ae)

0.16.1#

Bug Fixes#

  • Correct main file and types paths of graphql-serve package (d4d918e).

0.16.0#

New Features#

  • Use any knex 0.20.x or 0.21.x version in your application (d826b6f#1903)

  • Ability to specify composite unique columns in GraphQL Migrations (#1658), fixed by (9c6f34a231e2645c34533d58ea4427ff8f8f634e)

  • Requiring _id: GraphbackObjectID primary key for MongoDB (#1769). This fixes issues below related to primary key in MongoDB:

    • #1731, #1626 Ineffecient and wrong mapping of the id field
    • #1625 Filters on "id: ID" field not working

    NOTE: If you are migrating from 0.15 or previous versions of Graphback, you may be required to update relationship fields so that their values (previous stored as String) are of type ObjectID.

  • Add a @transient field annotation to ignore fields during input type creation and migrations 4076fa26

DataSync#

  • Using a _lastUpdatedAt field with a proper GraphbackTimestamp scalar and other minor fixes (#1771) including:

    • disabling conflicts in default configuration
    • adding a limit argument to sync Queries

Bug Fixes#

Breaking Changes#

  • Use GraphbackDateTime scalar for generated createdAt updatedAt fields (#1349, fixed by #1862)

Disable filter input generation for unknown custom scalars#

Graphback disabled generation of unknown custom scalars, except for Timestamp, Time, Date, DateTime, as we cannot reliably support scalars we do not know.

See Graphback Scalars for the list of officially supported scalars.

  • Replace @db(skip: true) field annotation with @transient 85d50f3c

Changed GraphbackCRUDService findBy method signature. This also applies to all services that implement this interface.#

- findBy(filter: QueryFilter<Type>, context: GraphbackContext, page?: GraphbackPage, orderBy?: any): Promise<ResultList<Type>>;
+ findBy(args?: FindByArgs, context?: GraphbackContext, info?: GraphQLResolveInfo, path?: string): Promise<ResultList<Type>>;

args

findBy now accepts a new interface, FindByArgs, which wraps the filter, page and orderBy optional arguments.

await noteService.findBy({
filter: {
id: {
gt: 100
}
},
page: {
offset: 0,
limit: 10
},
orderBy: {
field: 'id'
}
})

context (optional)

The context parameter is now optional.

info

You can now optionally pass the GraphQLResolveInfo info object to the CRUD service, to perform extra optimizations like retrieving only the selected fields from the query.

await noteService.findBy(filter, context, info);

path (optional)

The root path of the query to get the selected fields from. For example, to get id, title, description fields from the following query, you would set the path to items.

query findNotes {
findNotes {
items {
id
title
description
}
}
}

The path variable is optional, as it will automatically resolve to the root field of the entire query.

context parameter removed from subscribeToCreate, subscribeToDelete, subscribeToUpdate methods in GraphbackCRUDService.#

This method was unused.

Removed context parameter from all GraphbackDataProvider methods. This also applies to all providers that implement this interface.#

All CRUD methods in GraphbackDataProvider had a context parameter used to get the selected fields. These have been replaced with (optional) selectedFields - you can pass a string array of the fields you want to select from the database.

await noteProvider.findBy(filter, ['id', 'name']);

Changed GraphbackDataProvider findBy method signature. This also applies to all providers that implement this interface.#

args

findBy now accepts a new interface, FindByArgs, which wraps the filter, page and orderBy optional arguments.

await noteService.findBy({
filter: {
id: {
gt: 100
}
},
page: {
offset: 0,
limit: 10
},
orderBy: {
field: 'id'
}
})

Remove resolver options from GraphbackContext#

Resolver options (context.graphback.options) was removed from the context because the count aggregation and selectedFields extraction logic was moved to the CRUDService method.

Removed graphback key from GraphbackContext#

The graphback.services property has been removed from GraphbackContext, and graphback is now the service map property.

export interface GraphbackContext {
- graphback: {
- graphback: GraphbackServiceConfigMap
- }
+ graphback: GraphbackServiceConfigMap
}

Now you can reach the Graphback service map by calling context.graphback.Note.findBy(...).

CRUDService, DataSyncCRUDService now accepts a ModelDefinition as the first constructor parameter.#

To instantiate a CRUDService you must pass the full ModelDefinition instead of the model name.

const myService = new CRUDService(modelDefinition, ...);

KeycloakCrudService now accepts a ModelDefinition as the first constructor parameter.#

To instantiate a CRUDService you must pass the full ModelDefinition instead of the model name.

const myService = new KeycloakCrudService(modelDefinition, ...);

DataSyncProvider sync method signature has been changed#

- sync(lastSync: Date, context: GraphbackContext, filter?: any, limit?: number): Promise<Type[]>;
+ sync(lastSync: Date, selectedFields?: string[], filter?: QueryFilter, limit?: number): Promise<Type[]>;

The context argument has been replaced with (optional) selectedFields.

context parameter is removed from the create method in MongoDBDataProvider and DatasyncMongoDBDataProvider providers.#

This parameter did not do anything.

0.15.1#

Bug Fixes#

  • ensure field directives are mapped to the schema on relationship fields (#1797) (e8bf5c8)

0.15.0#

New Features#

  • add in-memory subscription filtering (#1748
  • add support for common scalar types (#1749)

Bug Fixes#

  • create-graphback was not correctly creating a fullstack application (#1778) (685aa4c)
  • throw an error if relationship annotation are missing (#1766). This fixes #1604 where when no relationship annotation is defined, invalid input fields are added to input type.

0.14.1#

Bug Fixes#

0.14.0#

Migrating to 0.14.0#

Breaking Changes#

Graphback 0.14 contains a lot of breaking changes that will improve and simplify your application code.

CRUD Mutation return types are nullable#

Previously, the CRUD mutation resolvers did not allow returning null. These can now be null.

- createNote(input: CreateNoteInput!): Note!
+ createNote(input: CreateNoteInput!): Note

Changed annotation syntax#

All annotations now use a uniform syntax format: @annotation(foo 'bar') that is similar to GraphQL Directives

Examples:

@oneToMany field: 'note'

becomes:

@oneToMany(field: 'note')
@db.type: 'timestamp'

becomes:

@db(type: 'timestamp')

Removed @crud annotation#

The @crud model annotation has been removed. To specify CRUD configuration on your model use the @model annotation.

"""
@model
@crud.delete: false
@crud.update: true
"""

becomes:

"""
@model(delete: false, update: true)
"""

@graphback/runtime package is removed#

Runtime package should no longer be used in top level API. All functionalities were moved to the @graphback/core package.

NOTE: Users should never have runtime or core packages imported in their applications and interact with graphback package as aggregator

API code generation is no longer supported#

In 0.14.0 Graphback now supports runtime generation of your schema, resolvers and services.

Please manually remove your generated schema and resolver files.

Remove @graphback/codegen-resolvers from your package.json.

To use our runtime API, refer to the Runtime API documentation.

New runtime API#

We have removed the complicated multi-step runtime API so that you can create your Graphback API in a couple of lines.

If you were already using the runtime API, replace this:

const runtimeEngine = new GraphbackRuntime(model, graphbackConfig);
const models = runtimeEngine.getDataSourceModels();
const services = createKnexPGCRUDRuntimeServices(models, model, db, pubSub);
const runtime = runtimeEngine.buildRuntime(services);

With this:

import { buildGraphbackAPI } from 'graphback'
import { createKnexDbProvider, createCRUDService } from '@graphback/runtime-knex'
import { PubSub } from 'graphql-subscriptions'
const { typeDefs, resolvers, contextCreator } = buildGraphbackAPI(modelDefs, {
serviceCreator: createCRUDService({
pubSub: new PubSub()
}),
dataProviderCreator: createKnexDbProvider(dbConfig)
});

For more advanced usage, refer to the Runtime API documentation.

Client code generation now generates all GraphQL documents into one file#

  1. Replace outputPath with outputFile in your client config
  2. Delete previously generated client documents and rerun generate command
  3. Be sure to correct your documents path in your codegen config if you use GraphQL-Code-Generator

@db.primary is removed, use @id instead#

We have replaced the @db.primary annotation with @id.

@db.default is removed, use @default instead#

We have replaced the @db.default annotation with @default. Now you can provide default values like this:

"""
@default(value: 'default value')
"""

instead of

"""
@db.default 'default value'
"""

Removed graphback db CLI command to migrate database#

We have removed the graphback db command. Database migrations can be only executed from the codebase when application is started.

See Database Migrations on how to use the code-based migrations in your API.

Removed graphback init CLI command#

We have removed the graphback init command, this has been replaced by a newly added micro-cli create-graphback.

Removed helper method to create CRUD services#

Previously you would have done this to create your context and a CRUD service for every model:

const context = createMongoCRUDRuntimeContext(models, schema, db, pubSub)

Now you can create your services and data providers with like this:

import { buildGraphbackAPI } from 'graphback'
import { createKnexDbProvider, createCRUDService } from '@graphback/runtime-knex'
import { PubSub } from 'graphql-subscriptions'
const { typeDefs, resolvers, services } = buildGraphbackAPI(modelDefs, {
serviceCreator: createCRUDService({
pubSub: new PubSub()
}),
dataProviderCreator: createKnexDbProvider(dbConfig)
});

For more advanced usage, refer to the Runtime API documentation.

Removed graphback openapi CLI command.#

We have removed the graphback openapi CLI command, but you can still use OpenAPI-to-GraphQL to create a GraphQL schema from your OpenAPI specification.

graphl-config is not supported in graphql-serve#

To use graphql-serve now you must use a model file:

gqlserve serve ./path/to/models/*.graphql --port 8080

SchemaCRUDPlugin only has a single configuration option#

We have removed the fileName and format options from SchemaCRUDPlugin. These can be inferred from the outputPath:

const schemaPlugin = new SchemaCRUDPlugin({
outputPath: './path/to/my/schema.js'
});

Remove format option from ClientCRUDPlugin#

The format option has been removed as you can specify the file extension in outputFile.

Deprecated#

  • PgKnexDBDataProvider has been deprecated in favour of KnexDBDataProvider.
New Features#
  • All client documents are now generated in a single file. The file's path is specified by the outputFile field in client config
  • outputPath in client config has been removed
  • Added new templates to graphback init commands. All templates now giving ability to add client side application.
  • Added a new, simpler runtime API
  • GraphbackPluginEngine accepts now object instead of arguments. new GraphbackPluginEngine({schema})

0.10.2#

graphql-migrations#

It's now possible to create database relationships from the 1:M side of your data model!

type User {
id: ID!
messages: [Message]
}
```openapi
This creates a `userId` foreign key column in the `message` table. Visit the [relationships documentation](../relationships#OneToMany) for more examples.
# 0.10.1
### Graphback-Codegen-Client
- Generate relationship variables in mutations, fragment, subscriptions, queries.
# 0.10.0
BREAKING changes for CLI/ and runtime.
### Graphback
- Added runtime layer
Runtime layer gives developers ability to run GraphQL server basing on input model
without code generation. All resolvers are created at runtime giving developers ability to update applications
on the fly. For more information please check official documentation for runtime layer.
- Deprecating graphback as way to interact with the Graphback ecosystem
Graphback package offers multiple helpers however to fully configure all generators and other capabilities
developers can use individual packages:

@graphback/codegen-client @graphback/codegen-resolvers @graphback/codegen-schema @graphback/core @graphback/runtime graphql-migrations

### GraphQL-Migrations
- Added a new library [`graphql-migrations`](https://github.com/aerogear/graphback/tree/master/packages/graphql-migrations) for executing database migrations.
- `migrateDB` directly compares the input model with the current database and uses the generated diff to update the database structure. This mode does not generate any migration metadata.
- `migrateDBUsingSchema` updates the database by comparing the input model with the previous model. This mode generates migration metadata which is persisted to the local filesystem and to the database.
# 0.9.1
### Templates
Removed REST template from official list of templates
# 0.9.0
### Graphback-cli
#### Breaking changes
Templates rely on `graphback.json` file. Please rename your `config.json` to `graphback.json` and add additional configuration entries
```json
"folders": {
"model": "./model",
"resolvers": "./src/resolvers/",
"schema": "./src/schema",
"client": "./client/src/graphql"
}
