The Express integration package for loopback-next.
This module introduces Koa style cascading middleware that leverage async/await. It also enables the ability to plug in existing Express middleware as LoopBack middleware or interceptors so that they can be used at sequence/action, global interceptor, and local interceptor tiers.
This module also serves as a standalone extension to Express to provide extensibility and composability for large-scale Express applications by leveraging LoopBack’s Dependency Injection and Extension Point/Extension pattern.
Interface LoopBack 4 middleware to be executed within sequence of actions. A middleware for LoopBack is basically a generic interceptor that uses RequestContext.The signature of a middleware function is described at Middleware. It’s very much the same as Koa middleware.
