go-grpc-middleware - Golang gRPC Middlewares: interceptor chaining, auth, logging, retries and more.

•    Go

---

gRPC Go Middleware: interceptors, helpers, utilities. gRPC Go recently acquired support for Interceptors, i.e. middleware that is executed either on the gRPC Server before the request is passed onto the user's application logic, or on the gRPC client either around the user call. It is a perfect way to implement common patterns: auth, logging, message, validation, retries or monitoring.

Chuck - An in-app HTTP inspector for Android OkHttp clients

•    Java

---

Chuck is a simple in-app HTTP inspector for Android OkHttp clients. Chuck intercepts and persists all HTTP requests and responses inside your application, and provides a UI for inspecting their content. Apps using Chuck will display a notification showing a summary of ongoing HTTP activity. Tapping on the notification launches the full Chuck UI. Apps can optionally suppress the notification, and launch the Chuck UI directly from within their own interface. HTTP interactions and their contents can be exported via a share intent.

Kakapo.js - :bird: Next generation mocking framework in Javascript

•    Javascript

---

Kakapo its a full featured http mocking library, he allows you to entirely replicate your backend logic in simple and declaritive way directly in the browser.
