The inRequestScope feature seems to be malfunctioning and is not functioning as intended

Need help with using inRequestScope in inversifyJS For example: 

container.bind<ITransactionManager>(Types.MysqlTransactionManager).to(MysqlTransactionManager).inRequestScope()

...
container.get<ITransactionManager>(Types.MysqlTransactionManager)//calling the MysqlTransactionManager constructor and returning the instance

container.get<ITransactionManager>(Types.MysqlTransactionManager) //constructor is called again, but I want the same instance returned instead of a new one

How can I ensure that the same instance is returned when get is called for the second time?

Answer №1

To streamline your code, you should encase both the .get calls within a unified class and then proceed to resolve that class using either .get or .resolve

Summary from official documentation

Every call made to these methods will not only resolve the main dependency but also all its subordinate dependencies. InversifyJS internally creates a dependency graph, referred to as the "resolution plan". When utilizing the inRequestScope scope, it maintains a single instance for objects appearing multiple times in the resolution plan, thereby reducing the number of necessary resolutions and serving as a potential performance enhancement in certain scenarios.
