Class ResponseDeflater

java.lang.Object

services.moleculer.service.MoleculerComponent

services.moleculer.service.Service

services.moleculer.web.middleware.HttpMiddleware

services.moleculer.web.middleware.ResponseDeflater

All Implemented Interfaces:

services.moleculer.service.MoleculerLifecycle, HttpConstants

public class ResponseDeflater
extends HttpMiddleware
implements HttpConstants

Compresses body of REST responses. Do not use it with ServeStatic middleware; ServeStatic also compresses the data. Use it to compress the response of REST services. Using this middleware reduces the performance, so use it only on slow networks. Sample:

restRoute.use(new ResponseDeflater(Deflater.BEST_SPEED));
