assertIsValidModuleName()

assertIsValidModuleName(moduleName): asserts moduleName is StringKeyOf<GraphQLModules>

Assert that the iterated moduleName is of ModuleName type, otherwise it may be just string e.g. when modules are iterated over using e.g. a for loop.

configure()

configure(config): void

Provide additional configuration after the ModuleContainer was created.

Keep in mind that modules are only decorated once after they are resolved, therefore applying any configuration must happen before the first resolution.

Parameters

• config: CombinedModuleContainerConfig<GraphQLModules, GraphqlServerOptions>

Returns

void

Inherited from

ModuleContainer.configure

Defined in

packages/common/dist/config/ModuleContainer.d.ts:119

Returns

void

Inherited from

ModuleContainer.configurePartial

Defined in

packages/common/dist/config/ModuleContainer.d.ts:120

create()

create(childContainerProvider): void

This is a placeholder for individual modules to override. This method will be called whenever the underlying container fully initialized

Parameters

• childContainerProvider: ChildContainerProvider

Returns

void

Implementation of

SequencerModule.create

Overrides

ModuleContainer.create

Defined in

packages/api/src/graphql/GraphqlSequencerModule.ts:69

decorateModule()

protected decorateModule(moduleName, containedModule): void

Override this in the child class to provide custom features or module checks

Parameters

• moduleName: StringKeyOf<GraphQLModules>

• containedModule: InstanceType<GraphQLModules[StringKeyOf<GraphQLModules>]>

Returns

void

Inherited from

ModuleContainer.decorateModule

Defined in

Inject a set of dependencies using the given list of DependencyFactories This method should be called during startup

resolve()

resolve<KeyType>(moduleName): InstanceType<ResolvableModules<GraphQLModules>[KeyType]>

Resolves a module from the current module container

We have to narrow down the ModuleName type here to ResolvableModuleName, otherwise the resolved value might be any module instance, not the one specifically requested as argument.

Type Parameters

• KeyType extends string

Parameters

• moduleName: KeyType

Returns

InstanceType<ResolvableModules<GraphQLModules>[KeyType]>

Inherited from

ModuleContainer.resolve

Defined in

packages/common/dist/config/ModuleContainer.d.ts:133

resolveOrFail()

resolveOrFail<ModuleType>(moduleName, moduleType?): ModuleType

Type Parameters

• ModuleType

Parameters

• moduleName: string

• moduleType?: TypedClass<ModuleType>

Returns

ModuleType

Inherited from

ModuleContainer.resolveOrFail

Defined in

packages/common/dist/config/ModuleContainer.d.ts:134

start()

start(): Promise<void>

Start the module and all it’s functionality. The returned Promise has to resolve after initialization, since it will block in the sequencer init. That means that you mustn’t await server.start() for example.
