Typesafe, (almost) Zero Cost Dependency Injection in TypeScript

1. proposal-decorators

   1 73 2,957 3.3

   Decorators for ES6 classes

   

   Unlike Java and C#, when TypeScript is transpiled to JavaScript the type information gets lost, making a TypeScript interface become nothing in JS. Because of this, it's not possible to use the interface itself as a token in the IoC Container. Decorators come in handy here to configure the service metadata in the Container.

12. dataloader

    11 51 13,371 2.8 JavaScript

    DataLoader is a generic utility to be used as part of your application's data fetching layer to provide a consistent API over various backends and reduce requests to those backends via batching and caching.

    

    The one example of using Scoped dependency that comes to my mind, it's HTTP request level caching for libs like dataloader.
